How To Build A Filter Box To Go Over In A Coil Air Conditioning Unit

Air Conditioning System Installation Process From Start to Finish

I am the Install manager at Fire & Ice, since 2017. I accept spent 28 years in this business and have experienced well-nigh every aspect of HVAC from Industrial, commercial, and residential buildings. From design, install, service, or sales, if it moves air, I've worked on it.

About This Article

An in-depth air conditioner installation procedure guide. Learn how installation procedures dramatically affect the lifespan and effectiveness of your air conditioner.

I'k non going to lie, the installation process for a new air conditioner is complicated. When customers enquire me what's involved in the process, they're often shocked to learn how much goes into it.

The more worrying fact is that in that location are many HVAC companies and air conditioner installers who don't know all the steps that should be part of a good installation. Information technology's like shooting fish in a barrel to cutting corners so that an A/C system runs "adept enough." But "good enough" often means losing thousands of dollars in energy costs over the life of your system, and decreased comfort for you and your family unit. This is unacceptable.

Practice you want a sleek, efficient motorcar powering your ac, or a comfort-robbing trashcan outside your home? I'm guessing yous'd prefer the old. Well, you're in luck.

In this commodity, we are going to cover the entire air conditioner installation procedure in detail, from starting time to finish! If you lot're committed to getting the most from your ac system, read on. Past the end, you'll have the peace of mind that comes with agreement each pace. Information technology will also allow y'all to selection a visitor whose installation process is up to snuff.

Importantly, this is non a DIY guide. Air workout installation should e'er be handled by a licensed professional. Once you read each pace involved, it should exist easy to run across why.

Planning the Replacement or New Installation of Your Key Air Conditioner

The world has changed so much in just the by few years. So imagine how much has changed in 10 years. Or 20. Or 30.

Virtually existing air conditioners that are replaced today are betwixt the ages of viii to xxx years sometime.

Mod air conditioners are 20-50% larger in height, length, and width. This allows for a larger coil which, in turn, makes the air conditioner more than efficient. Because of the larger size of mod air conditioners, the current location of your existing air conditioner may not accommodate the new ane. Sometimes the air conditioner must be relocated, particularly if at that place are state or manufacturer regulations on space clearances surrounding your unit. Others crave that unit to be within a certain distance to the utility meter. In some cases, this creates additional costs.

This is the first consideration for a homeowner, because it may require moving equipment or modifying your abode's ductwork.

So what's the adept news? Modern air conditioners are significantly quieter and more efficient than their predecessors, so your costs are often offset by these benefits.

Collecting A/C Information During the Domicile Estimate

During your initial in-dwelling visit, the figurer has the responsibility of reviewing the existing ac system. Important data needs to be collected so they tin can provide you an accurate proposal. This information is so passed to the installation squad.

Depending on the job, specialized equipment may be needed, which the installation team can bring with them because of this pace.

Having the proper information earlier the twenty-four hour period of installation increases the chances of the job being completed successfully and promptly.

The Arrival of the Install Squad, Review, and Safety

Before your installation team arrives, you should receive a call or text letting you know they're on their way.

Many good HVAC Companies will too send pictures accompanied by bios of the installation team that will exist working at your home ahead of time. This is an boosted condom and condolement factor before a stranger enters your habitation.

Once they arrive, the lead installer will share and review the chore information with you lot. This is often included in a packet that includes details of the job. This bundle contains the equipment information, accessories to be installed, and any special instructions given by you to the reckoner earlier the sale.

It'southward of import to permit a few moments for this review. This will forestall costly and aggravating mistakes from happening during the installation. Advice is a key component to a successful installation.

While you are reviewing the chore details with the pb installer, the other member(south) on the team will employ this fourth dimension to showtime laying downwards flooring protection and getting tools and equipment in place. They will likewise start a rubber process that includes turning off electrical circuits and gas supply to the existing HVAC equipment.

Removing Your Existing Fundamental Air Conditioner

Your existing air conditioner contains a refrigerant that needs to be removed before a new one can be installed. According to the EPA standards, it is unlawful to openly vent this refrigerant into the temper.

A device known as a recovery machine must be used along with a recovery tank to safely and legally remove the refrigerant in the existing key air conditioner organization. This is the only process that allows for the rubber removal and proper handling of the refrigerant.

Any individual treatment any refrigerant or equipment containing refrigerant must have an individual EPA certification. An EPA certification just certifies the name listed on the certification. Therefore, each member of the installation team, service squad, or anyone who might handle refrigerant or equipment containing refrigerant are required past law to have their ain private EPA certification.

Once the refrigerant is recovered properly, electrical wiring is disconnected from the existing air conditioner. Near the air conditioner is a disconnect box, which is a condom device in case of emergencies. It can shut downwardly your A/C unit of measurement.

From the disconnect box, a "whip" (flexible electric conduit) carries the ability to the air conditioner. Good HVAC companies replace the disconnect and the whip when replacing an air conditioner, to ensure system safety.

In cases where an old system lacks a disconnect box, a new one is required by rubber codes to be installed with the new air conditioner. There are specific installation guidelines for sizing and wiring the disconnect properly.

The circuit breaker should be turned off in the electrical panel before any work is to exist done inside the service disconnect. Once all the existing connections are safely removed, the existing air conditioner is gear up to be removed.

Preparing the Expanse for the New Key Air Conditioner

In most cases, the existing location of the air conditioner will require some prep work earlier the new air conditioner can be set up in identify. This prep work includes replacing the pad that the new air conditioner will set on.

New air conditioners are larger and taller than their predecessors. There are also times when the ground has sunk. Before the new pad can be set, the ground must be leveled. Good HVAC companies utilize a gravel base to level out or build up the area where the new air conditioner will be placed.

Some people call up information technology is ameliorate to accept a concrete pad poured for the new air conditioner to set up on. A concrete pad is not necessary and tin can cleft and shift drastically. When this happens, information technology is very difficult to repair or remedy. Instead, a composite pad is recommended. The blended pad is purposely designed to be exterior and last the lifetime of the new air conditioner. Additionally, information technology'due south often amend equipped than physical to absorb vibrations from the machine, which tin reduce noise and shaking.

Air Conditioner Sitting On Unleveled Concrete Block Air Conditioner Sitting On Leveled Composite Pad

Once the new air conditioner is installed, it cannot exist moved or lifted safely without damage in near cases. Many internal elements are rigid and pressurized. Moving it subsequently it is connected could permanently damage the system. A composite pad can avert damage to the air conditioner if it needs to be leveled in the time to come.

Removing the Existing Indoor Evaporator Coil

The indoor evaporator scroll is the other half of your air-conditioning organisation that sits above the furnace, though in some cases it volition sit below the furnace. This is what the other stop of the refrigerant lines are connected to.

The indoor evaporator gyre has two variations. I is cased and the other is uncased. In either awarding, the sheet metallic plenum must be disconnected before the new coil can be installed. This process can be complicated when access to the coil is restricted.

Furnace, Cased Evaporator Coil, and Plenum

The most common restrictions are rooms built around the arrangement such every bit closets or finished basements. This prevents access to all sides of the coil or plenum. An additional accuse may be added to the toll of the job based on difficulty. Because most indoor coils are more efficient, they are taller. Boosted prep work to the supply plenum may be required earlier the new scroll can be installed.

Removing the Existing Copper Refrigerant Lines (Line Gear up)

Next, the existing refrigerant line set can be removed. This is a gear up of 2 copper lines through which the refrigerant travels from the outdoor condenser, then back into the indoor evaporator curl.

The refrigerant line set is unremarkably strapped to the bottom of the floor joists. These straps are removed, and the line set is taken down. It'southward recommended that the line set exist replaced in every case that it is exposed and accessible.

Refrigerant travels through the lines along with oil. In older air conditioning systems, the oil in the existing line ready is different from the oil found in the new air conditioner. These oils cannot be mixed without damaging the new air-conditioning system.

Sometimes the line set up is concealed by a ceiling or in a wall, or it is buried clandestine or in concrete. Sometimes providing access is non an choice or possible. In these cases, you have the option of finding a new location to run a new line gear up or reusing the existing line set remains. If the existing line set up must be reused, it must be flushed and cleaned properly, then pressure tested. It is never recommended to keep an existing line set if it can exist replaced.

Installation of the New Indoor Evaporator Gyre

In that location are 2 options when installing a new evaporator coil for any new air conditioner organisation: cased and uncased. The preferred option is a cased coil, because it comes in an insulated cabinet with removable panels on the front that let access to the coil within.

The cased coil is too designed to sit on top of the furnace without whatsoever modifications, which makes repairs and modifications easy. In virtually cases, information technology will exist painted to match the color of the furnace. The biggest do good of using a cased curl is that it comes pre-cased by the manufacturer. This makes failure from an improper installation highly unlikely, regardless of the skill level of the installer.

When using a cased ringlet, it is already "installed" by the manufacturer and simply needs to be placed on the top of the furnace. The final pace at that bespeak is to connect and seal it to the existing sheet metallic plenum.

Cased Evaporator Coil Cut-Out

An uncased roll is the coil without an insulated cabinet. They have more installation requirements and longer preparation fourth dimension. They are available in the same variations as the cased coil.

Uncased coils are typically more difficult to install. However, an uncased coil will provide the aforementioned comfort and be merely as efficient as a cased coil when installed properly.

Before the curlicue can exist built into the existing sheet metal supply plenum, at that place is specific grooming required. These requirements are specified by the manufacturer. Failure to follow the installation transmission's guidelines may upshot in damage to the furnace as well as the coil.

The drain pan on the coil is plastic, so track need to be fabricated by the installer to make sure the coil is sitting the proper altitude in a higher place the furnace heat exchanger. This keeps the drain pan from melting. If the drain pan melts into the furnace, it could permanently damage the furnace or cause a fire.

Once the rails are built and installed, the scroll tin be installed into the supply plenum. If the plenum is larger than the coil, a sheet metallic pan must be built with an opening provided below the curl. This opening needs to mirror the bottom opening of the coil for proper airflow from the furnace going through the gyre.

If the opening is not big enough, or too much air goes effectually the coil instead of through it, the coil will freeze into a block of ice. This can damage the coil and crusade a refrigerant leak by cracking the tubing conveying the refrigerant.

Once those are installed, the final footstep is building the front end of the plenum. It is possible to build an admission panel door into the plenum to cover the curlicue. This is not required by any code or manufacture specification, so it would exist upwardly to the installer. In all scenarios, the cover must have holes provided for the refrigerant lines, so also for the condensation lines to be continued.

The type of curlicue chosen is mostly based on the details of the installation. Some won't permit for a cased curlicue due to sizing restrictions, for instance. Regardless, if the coil is installed per code and manufacture specifications to the existing duct system, can drain properly, and is sealed from air leaks, you lot volition bask the same level of comfort. There is no difference in warranty or life expectancy between either type of gyre.

Installation of the New Copper Refrigerant Lines (Line Set)

The new refrigerant line set is a combination of two individual copper lines. Ane line is always bigger than the other and is insulated. The bigger line is called the suction line, and the little i is called the liquid line. They come up packaged together, rolled in a coil. Information technology is available in multiple selections of lengths, from xv-l feet. You lot will rarely demand more than 50 feet in a residential home.

The primal is installing the line with as few bends and turns every bit possible. When these bends are necessary, the soft copper can exist bent by hand or a tubing bender.

It's mutual to install the line set as close to your home'south beams and ductwork as possible. Information technology's besides recommended that you secure the line every four-6 feet. Plastic or copper strapping is common. Metal straps or clamps can be used, but information technology's important to protect the copper wiring if the clamps bear on them.

If y'all don't properly protect the line, it can corrode. Galvanic corrosion (too called bimetallic corrosion) is the breakup of metal when two dissimilar metals come into contact. This does take some time to occur. Withal, if allowed to occur, it could eventually reduce the integrity of the copper refrigerant line over fourth dimension until it causes a leak.

After the hangers are installed, the line ready can now be put in place. Typically, an installer will start with the suction line and curlicue out one end a few feet, leaving the residuum of the roll in a coil. They and then push the unrolled section through a hole drilled through the band board of the house to the outside, near the air conditioner. Plenty of the line is pushed out to reach the service valve of the air conditioner.

Eventually, the installer will connect this line to the air conditioner itself. The hole size volition be betwixt 2-2.5" in diameter, depending on the type of line gear up being used.

Later the line is outside by the air conditioner, the line is secured past hangers almost the hole and so another hanger back a couple of anxiety. The line is and then advisedly uncoiled and formed along the floor joists up against the trunk line ductwork or a axle, as straight as possible until long radius turns or bends are needed. Along the style, it gets put into the hangers that have been installed previously, securing it in place.

The line set will run from the air conditioner outside to the new indoor evaporator roll on height of the furnace. After the suction line has been installed and secured, the smaller, liquid line is run along the suction line, secured in the aforementioned hangers.

A line prepare should be new, installed every bit one piece, free from whatever sharp bends or kinks, and secured with an advisable hanging system.

There will besides be a pocket-sized, depression-voltage control wire that runs from the furnace along the line set to the air conditioner exterior. The small existing wire coming from the thermostat to the furnace sends a low voltage indicate to the air conditioner to plough on and off when a call for cooling is needed or has been satisfied.

Setting the New Air Conditioner Condenser

So far, we've set the pad, leveled it, and our refrigeration lines and electric disconnect are set up to be wired into the new air conditioner condenser.

Removing the new air conditioner and setting information technology on the pad is step one. Later uncrating the unit, a good installer volition inspect for any damage. Sometimes panels or coils will get damaged in transit. Any damage should be reported to you immediately.

Fire & Ice Heating and Air Conditioning runs multiple inspections on equipment, both when it arrives and when information technology's installed, to ensure it is in working club.

If there is a dent, that doesn't necessarily mean there is any damage that will affect performance. However, you always have the right as a customer to not accept the damaged unit and inquire for another one.

The line set that was installed in the previous step is and so formed and fitted to the appropriate service valve on the new air conditioner. The service valve is a connection point for the line set, and also isolates the refrigerant contained within the unit. Service valves also allow for the outdoor condenser portion of the air conditioner to exist isolated from the indoor scroll and line ready for futurity service or repair needs when needed.

Isolating the refrigerant keeps you from having to replace it with all new refrigerant in instance of a repair in the future.

Later the line set is fitted to the service valves, they must be brazed in. Brazing, a class of welding, is a procedure using 2 gases (oxygen and acetylene) and a filler rod made of an alloy metallic and argent to join the copper line fix and service valves. The valves are heated to a minimum of 1200 degrees Fahrenheit or until the filler rod will menses to weld the connectedness.

If this process is completed properly, the copper line set, the filler rod, and the service valve are all melted together for a tight, leak-complimentary connection.

Filter Dryer Installation

Filter driers are a key component in the refrigerant system. They serve 2 main functions. The most important role of a filter drier is to absorb moisture. The second is to provide physical filtration.

When installing a new air conditioner condenser, you lot must always install a liquid line filter drier into the refrigeration system. Nearly new air conditioner condensers come with a liquid line filter drier for yous to install.

Manufacturers recommend the filter drier exist installed close to the expansion valve (TXV) at the indoor coil, equally often as possible. This keeps the TXV protected and keeps the filter drier from beingness exposed to weather where information technology could rust.

There is too an arrow for menstruation direction. This arrow must ever exist in the direction that is going into the indoor coil.

Whatever contaminants in the refrigeration system are harmful. Water or wet is the worst.

Wet enters the system in different ways. If a system is non evacuated properly, wet will exist in it. Moisture can also come from leaks or motor windings. The h2o can cause corrosion and create failure in metallic parts.

Water or moisture tin also react with the oil in the refrigerant system. This is called hydrolysis, which forms acids in the system. Acids, wet, or any other contamination in the lines will be extremely dangerous to the integrity of your new air conditioning system.

All skilful HVAC companies have strict processes in place for their install teams to preclude failure equally much every bit possible. Any time a refrigerant line is open up to the atmosphere, information technology is vital to install a new filter drier. This is true of installations equally well as service repairs.

This brazing process is the same for connexion to the indoor evaporator scroll. This, again, involves open flames and should only be performed by a trained professional.

The gases used in the process are explosive. There is an open flame exterior and inside the home. It can be dangerous to the installer, the homeowner, and the dwelling house, causing permanent impairment without proper training. Post-obit manufacturer and condom guidelines is key.

Preparing the line set up for refrigerant in this manner is the nigh important pace in ensuring the safety and efficiency of your air conditioner.

Sadly, this process is unknown or not followed to most install teams. Not all companies are equal in grooming or processes, and many contractors lack the proper equipment. A good HVAC company will have all the tools and processes needed to install the air conditioner professionally and thoroughly.

After the line set is fitted properly into the service valves and indoor roll, heat protection needs to be applied. Heat protection can be a oestrus-absorbing paste, wet towels, or rags. Anything that would keep the rut spreading into either of the coils is acceptable. The service valves on the outdoor condenser incorporate rubber O-rings that will cook if they aren't protected. If the valves are overheated and the O-rings are damaged, the refrigerant will leak past the valve into the line prepare, losing the factory accuse.

From the factory, the air conditioner condenser is prepared, cleaned, and the refrigerant is added. If the refrigerant is exposed before the procedure is completed, it becomes contaminated, forth with the condenser coil. If this footstep is performed improperly, all the refrigerant would demand to be recovered and the condenser coil would need cleaned and prepared again before any refrigerant could be added.

Most indoor coils take a metering device called an expansion valve that will be damaged if not protected from the oestrus during brazing. If these become besides hot, or any contaminants are introduced, the expansion valve will be compromised and neglect to operate.

Once the oestrus protection is completed, a tank containing a gas chosen dry nitrogen is hooked upwardly to a regulator and possibly a manifold estimate ready. This allows the nitrogen to be purged while brazing. The nitrogen protects the inside of the copper tubing from oxidizing during brazing. The damage will not always be present immediately.

The HVAC manufacture requires brazing with nitrogen every time to prevent this impairment.

Brazing with nitrogen, when done properly, volition give the organization maximum opportunity for operation, reliability, and dependability. Later on the system is brazed in both the indoor and the outdoor components, it must be checked for leaks using the same dry nitrogen, up to a specific amount of pressure. Using the dry out nitrogen to pressure level examination the arrangement achieves three things:

It's a preliminary leak test.
The dry out nitrogen volition pick upwards moisture.
It will also purge some contaminants out of the arrangement upon its release.

It is very of import to verify with the installation manual provided by the manufacturer what they recommend for pressure. Most systems are designed for 150 PSI when testing.

If there is as well much pressure added, problems tin occur. If the pressure is likewise high for the O-ring seal, for instance, the nitrogen will bleed into the refrigerant, contaminating it.

In this scenario, all the refrigerant contained in the condenser from the factory will exist compromised and will have to be recovered, then the gyre cleaned and prepped for more than refrigerant.

If the preliminary leak test with nitrogen holds for a minimum of 10 minutes, then it's time to move on to the next crucial step: vacuuming the system.

Typically a system is vacuumed to a minimum of 500 microns. The manufacturer's recommended vacuum is found in the installation manual. Refrigeration systems are designed to operate with only oil and refrigerant flowing through them.

Our temper is fabricated up of oxygen, nitrogen, and wet. These are enemies to the system's operation and may enter the organisation during installation or servicing. Removal of these, forth with air or other non-condensable products, is required. This is achieved through the vacuum process when installing the air conditioner. The vacuum process can take no less than 30 minutes and up to an hour or more depending on the size of equipment coils and length of line ready.

Failure to provide a dry, wet-free temper before introducing the refrigerant into the rest of the system will in all cases promote an inconsistent operation, and eventually permanent failure of the arrangement.

To achieve a successful vacuum on an air conditioning system there are several key tools and equipment that must be used:

A reliable vacuum pump
A micron gauge
Manifold and hoses
Vacuum rated core removal tool

The vacuum must achieve 500 microns or less in the system and concord the vacuum for this to be successful. This is also the second and terminal leak exam. If a system does not hold a vacuum, then there is a leak somewhere.

Once a proper vacuum is accomplished and has proven to concur, the arrangement is ready to have refrigerant introduced to information technology. Refrigerant is the just product that can "break" the vacuum. If hoses are asunder from the system earlier the refrigerant has been released into the system, the atmosphere will interruption the vacuum. If this happens, the vacuum process must be redone before refrigerant can be introduced.

With the hoses still connected to the service valves of the air conditioner, the refrigerant is released into the organisation, breaking the vacuum past opening the suction-side service valve first followed by the liquid side second.

Installation of the New High- and Low-Voltage Wiring

For the air conditioning system to operate, the high- and low-voltage wiring must exist reconnected. Using the existing power supply from the electrical panel within the habitation, the installer will mount a new service disconnect box. The disconnect is mounted securely to the side of the business firm using advisable fasteners, based on the type of surface information technology is beingness mounted to.

In that location are 2 main types of disconnect boxes. One is fused and the other is non-fused. They are both appropriate to use outdoors. A fused disconnect allows the proper overcurrent protection required by the manufacturer. This blazon is nigh common and required when the primary circuit from the panel exceeds the maximum required overcurrent protection. It also allows for additional safety to the air conditioner condenser.

A non-fused disconnect may exist used only in cases where the breaker matches identically to the manufactures listed maximum overcurrent protection. There is a minimum and a maximum required overcurrent protection. You must be within these guidelines. The system will not pass the code requirements if they are not.

For example, if you have an existing xl-amp circuit that supplies the disconnect, only the listed overcurrent protection is just 30 amps, y'all must utilize the fused disconnect and install 30-amp fuses with it to properly protect the air conditioning condenser. If the amperage from the breaker matches the maximum or the minimum overcurrent protection, a non-fused disconnect is acceptable.

The service disconnect has specific locations for the high voltage circuit from the panel to be connected and specific locations for the power to get to the air conditioner itself through the electric whip. They are identified as "Line" (wiring from the electric console) and "Load" (the whip that takes power to the air conditioner). This allows the pull inside the service disconnect to interruption or disconnect the power supply to the air conditioner without having to close the billow off from the main panel.

Because the air conditioner is outside, it would be cumbersome to run in and out of the house to plough the power on or off in instance of emergency or servicing. The service disconnect is required by state and local code requirements.

At that place are as well requirements for placement of the air conditioning condenser. Information technology boils down to making certain there is proper accessibility. All the electric connections should be made according to the NEC (National Electrical Lawmaking). The depression-voltage control wire is connected direct into the air conditioning condenser at the proper locations according to the air conditioning condenser installation instructions.

This is the "signal" from the control lath in the furnace sent through the wire to the air conditioner when the thermostat calls for cooling. The low-voltage command wire is what allows the air conditioner to cycle according to the parameters set regarding temperature and humidity inside the domicile. The low voltage wiring is continued to the command board inside the furnace on designated terminals.

AC Line Installation

Installation of the Condensate Drain Line

The moisture removed from the habitation during the cooling procedure travels down a plastic PVC pipe. It must exist continued to the primary side of the evaporator coil. The evaporator coil has a main and a secondary bleed location. The master condensate drain line will travel from the indoor evaporator curlicue to an appropriate floor drain or condensation pump.

A condensation pump is used where a proper flooring bleed does not exist in the home. In that location are also other reasons where a condensate pump is required or is benign to install. The important affair to remember if a condensate pump is used is that it must be serviced a minimum of twice a year to maintain proper performance.

Any condensate tubing or pipe should be secured and glued with the proper cement. A trap and an overflow safety switch must also be installed in the condensate system. This is to protect the equipment and the area from flooding due to a brake. The safety overflow switch is connected to the secondary port on the indoor evaporator roll and wired into the furnace command to close down the system when it is tripped.

Commissioning a new air conditioner

Startup Commissioning Process

The startup and commissioning (testing) process is done later on the organization is completely installed and gear up to operate. The organization is turned on and must run for 15-twenty minutes. This will allow the refrigerant to period through the system and first the air conditioning process.

Upon initial startup of the new air-conditioning system, the house should exist very warm or have a "load" with a warm enough temperature inside the domicile to permit for the minimum potential to charge the organisation accurately. A temperature to a higher place 75 degrees Fahrenheit is recommended in most cases. This allows the components in the air conditioning arrangement to be in full operation to allow maximum cooling potential during charging.

Sometimes running the furnace to heat the firm is a mutual practice to provide the necessary load on the home. After 15-xx minutes of operation, the system can now be commissioned.

A good installer will check the thermostat functioning, system sequence of operation, and multiple other areas. While the arrangement is operating, the post-obit data is important to collect to ensure proper operation within manufacturers' specifications:

Suction and liquid line pressure
Suction and liquid line temperature
Superheat
Subcooling
Outdoor ambient dry out bulb temperature
Indoor ambient dry seedling temperature
Indoor moisture bulb temperature
Return air temperature
Supply air temperature
Static force per unit area from return side, supply-side, and total static readings
Temperature driblet calculated
High voltage electric current reading
Amperage on the blower motor, outdoor fan motor, and compressor
Low voltage electric current reading
Line set length
Amount of refrigerant, if whatsoever, added to the system
Distance above or below the outdoor unit is in relation to the indoor coil
Blower speed tap/CFM recorded

This is the basic list of the proper information that should be known and recorded. This is the only fashion to know for sure how the system is operating and if it is within manufacturing specifications. If whatever of these do not fall within manufacturer specifications, your system may non exist warrantied past the manufacturer.

Commissioning is important for several reasons. For you, the peace of mind that you are receiving a properly set up and adapted arrangement for maximum condolement, efficiency, and dependability. It too ensures the manufacturer'southward warranty volition exist in full effect. The benefit to the company installing the system is that it gives a baseline of operational functioning in case whatever issues ascend later.

Information technology also gives the installing team confidence that before they leave, your arrangement is in perfect performance. It is very common for systems to exist installed and started upwardly without much consideration for proper commissioning.

Unfortunately, many companies turn it on and walk away the moment cold air is coming through the vents.

Proper commissioning is a specific procedure that requires training and special equipment to perform the process correctly. It also requires additional time and labor on a job site. Commissioning is the but way to know for certain exactly how well your system is operating.

Why would a company skip this pace, and so? In a word: cost. Skipping this procedure costs a company less, which in plow might lower your initial investment slightly. This is a long-term gamble, though, with your coin, your safe, and your comfort.

A adept HVAC contractor will take trained installation teams that will properly commission your air conditioner before they go out the job.

Clean up and Closing Process

The cleanup process is comparatively uncomplicated. All fabric and erstwhile equipment should be loaded upwards and taken away from the habitation. The floor protection should be rolled up concluding, keeping all debris from the installation within the drop cloth and out of your home.

All areas should be swept and free of whatever materials or droppings. Y'all should expect to see the area in the same condition in which it was plant.

A walkthrough of what was done during the installation should be completed with y'all. Going over safety, maintenance, warranty, and all special instructions are expected.

As a terminal mechanical step, a locking cap should be placed on the outdoor portion of the unit. This cap can simply be unlocked with the correct key. This is to forestall tampering with your equipment, and also to prevent theft of the refrigerant. This cap is ofttimes a specific color, which volition let a technician know which blazon of refrigerant your system uses.

A visual inspection of the work completed should also exist offered. Finally, a review of the commissioning and thermostat operation. After the final walkthrough, last signatures and payments are nerveless.

Installation Completed Professionally

The task is now complete!

The process may seem long and complicated, merely in the hands of a skilled installation team, the entire process should be second nature.

Don't cutting corners with installation. Your money and comfort are at risk if any of these steps are skipped. Knowing the total procedure will let yous to agree companies answerable when you decide to invest in a new air conditioning system. The result will be a comfy, efficient, long-lasting product.
