How To Bend Ac Line Set
Air Conditioning System Installation Process From Commencement to Stop
I am the Install manager at Fire & Ice, since 2022. I take spent 28 years in this business and take experienced nearly every aspect of HVAC from Industrial, commercial, and residential buildings. From blueprint, install, service, or sales, if it moves air, I've worked on it.
An in-depth air conditioner installation process guide. Larn how installation procedures dramatically affect the lifespan and effectiveness of your air conditioner.
I'thousand not going to lie, the installation process for a new air conditioner is complicated. When customers ask me what's involved in the process, they're often shocked to learn how much goes into information technology.
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. It's easy to cut corners so that an A/C system runs "good plenty." But "good plenty" often means losing thousands of dollars in energy costs over the life of your organisation, and decreased comfort for you lot and your family. This is unacceptable.
Practise y'all want a sleek, efficient auto powering your air conditioning, or a comfort-robbing trashcan outside your home? I'm guessing you lot'd prefer the former. Well, you're in luck.
In this article, we are going to embrace the unabridged air conditioner installation process in detail, from get-go to end! If you're committed to getting the near from your ac system, read on. By the end, you'll accept the peace of mind that comes with understanding each step. It will also permit y'all to option a visitor whose installation process is up to snuff.
Importantly, this is non a DIY guide. Ac installation should ever exist handled by a licensed professional person. In one case you read each step involved, it should be easy to see why.
Planning the Replacement or New Installation of Your Primal Air Conditioner
The world has changed then much in merely the past few years. So imagine how much has changed in ten years. Or 20. Or 30.
About existing air conditioners that are replaced today are betwixt the ages of 8 to 30 years former.
Modern air conditioners are 20-50% larger in tiptop, length, and width. This allows for a larger coil which, in turn, makes the air conditioner more efficient. Considering of the larger size of modernistic air conditioners, the current location of your existing air conditioner may non arrange the new one. Sometimes the air conditioner must be relocated, specially if there are state or manufacturer regulations on space clearances surrounding your unit. Others require that unit of measurement to be within a certain altitude to the utility meter. In some cases, this creates boosted costs.
This is the commencement consideration for a homeowner, because it may require moving equipment or modifying your abode's ductwork.
So what's the good news? Modern air conditioners are significantly quieter and more than efficient than their predecessors, and so your costs are often offset by these benefits.
Collecting A/C Information During the Abode Estimate
During your initial in-habitation visit, the estimator has the responsibility of reviewing the existing air conditioning system. Important data needs to be collected so they can provide you an authentic proposal. This information is then passed to the installation team.
Depending on the job, specialized equipment may be needed, which the installation team can bring with them because of this step.
Having the proper information earlier the day of installation increases the chances of the job being completed successfully and promptly.
The Inflow of the Install Squad, Review, and Safety
Earlier your installation squad arrives, you should receive a call or text letting you know they're on their fashion.
Many good HVAC Companies volition also send pictures accompanied by bios of the installation team that will be working at your home ahead of time. This is an additional prophylactic and comfort factor before a stranger enters your home.
One time they make it, the pb installer will share and review the job information with you. This is often included in a packet that includes details of the job. This packet contains the equipment data, accessories to exist installed, and any special instructions given by you lot to the estimator before the auction.
It's important to allow a few moments for this review. This will prevent costly and aggravating mistakes from happening during the installation. Advice is a fundamental component to a successful installation.
While yous are reviewing the chore details with the lead installer, the other fellow member(south) on the team will use this fourth dimension to start laying down flooring protection and getting tools and equipment in place. They will also start a safe procedure that includes turning off electrical circuits and gas supply to the existing HVAC equipment.
Removing Your Existing Central Air Conditioner
Your existing air conditioner contains a refrigerant that needs to be removed before a new ane tin exist installed. Co-ordinate to the EPA standards, it is unlawful to openly vent this refrigerant into the atmosphere.
A device known equally a recovery automobile must be used along with a recovery tank to safely and legally remove the refrigerant in the existing central air conditioner system. This is the only process that allows for the safety removal and proper treatment of the refrigerant.
Any individual handling any refrigerant or equipment containing refrigerant must take an individual EPA certification. An EPA certification just certifies the name listed on the certification. Therefore, each member of the installation squad, service team, or anyone who might handle refrigerant or equipment containing refrigerant are required by law to have their own individual EPA certification.
One time 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 safety device in case of emergencies. It can close down your A/C unit of measurement.
From the disconnect box, a "whip" (flexible electrical conduit) carries the power to the air conditioner. Skillful HVAC companies replace the disconnect and the whip when replacing an air conditioner, to ensure system safety.
In cases where an old organization lacks a disconnect box, a new 1 is required by safety codes to exist 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 electric panel before whatsoever work is to be done inside the service disconnect. One time all the existing connections are safely removed, the existing air conditioner is set up to be removed.
Preparing the Area for the New Central Air Conditioner
In most cases, the existing location of the air conditioner volition require some prep work earlier the new air conditioner tin can be set in place. This prep work includes replacing the pad that the new air conditioner volition set on.
New air conditioners are larger and taller than their predecessors. There are also times when the ground has sunk. Earlier the new pad can be prepare, the ground must be leveled. Good HVAC companies use a gravel base to level out or build up the expanse where the new air conditioner will exist placed.
Some people retrieve it is better to have a concrete pad poured for the new air conditioner to assault. A concrete pad is not necessary and tin cleft and shift drastically. When this happens, it is very difficult to repair or remedy. Instead, a composite pad is recommended. The composite pad is purposely designed to be outside and last the lifetime of the new air conditioner. Additionally, it'due south oft amend equipped than physical to absorb vibrations from the machine, which can reduce noise and shaking.
In one case the new air conditioner is installed, it cannot exist moved or lifted safely without harm in most cases. Many internal elements are rigid and pressurized. Moving information technology later on information technology is connected could permanently damage the system. A composite pad can avert damage to the air conditioner if information technology needs to be leveled in the future.
Removing the Existing Indoor Evaporator Curlicue
The indoor evaporator whorl is the other half of your air-conditioning system that sits above the furnace, though in some cases it will sit beneath the furnace. This is what the other end of the refrigerant lines are continued to.
The indoor evaporator coil has two variations. One is cased and the other is uncased. In either awarding, the canvass metal plenum must exist disconnected earlier the new coil tin be installed. This procedure tin be complicated when access to the coil is restricted.
The most common restrictions are rooms congenital around the organization such as closets or finished basements. This prevents access to all sides of the gyre or plenum. An boosted charge may be added to the cost of the job based on difficulty. Considering near indoor coils are more efficient, they are taller. Additional prep work to the supply plenum may be required before the new coil can be installed.
Removing the Existing Copper Refrigerant Lines (Line Set)
Next, the existing refrigerant line prepare can exist removed. This is a gear up of two copper lines through which the refrigerant travels from the outdoor condenser, so back into the indoor evaporator ringlet.
The refrigerant line set is ordinarily strapped to the bottom of the floor joists. These straps are removed, and the line set is taken downwards. It'due south recommended that the line set be 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 set is different from the oil constitute in the new air conditioner. These oils cannot be mixed without damaging the new air conditioning system.
Sometimes the line set is curtained by a ceiling or in a wall, or it is cached underground or in concrete. Sometimes providing access is not an option or possible. In these cases, yous have the option of finding a new location to run a new line set up or reusing the existing line set remains. If the existing line ready must be reused, information technology must be flushed and cleaned properly, then pressure tested. It is never recommended to continue an existing line set if it can exist replaced.
Installation of the New Indoor Evaporator Coil
There are 2 options when installing a new evaporator curlicue for whatever new air conditioner arrangement: cased and uncased. The preferred choice is a cased ringlet, considering it comes in an insulated cabinet with removable panels on the front that allow access to the whorl inside.
The cased curl is likewise designed to sit on top of the furnace without any modifications, which makes repairs and modifications like shooting fish in a barrel. In most cases, it will be painted to match the color of the furnace. The biggest benefit of using a cased coil is that it comes pre-cased past the manufacturer. This makes failure from an improper installation highly unlikely, regardless of the skill level of the installer.
When using a cased coil, information technology is already "installed" by the manufacturer and only needs to be placed on the top of the furnace. The final step at that bespeak is to connect and seal information technology to the existing sheet metal plenum.
An uncased curlicue is the coil without an insulated cabinet. They have more than installation requirements and longer preparation time. They are available in the same variations every bit the cased coil.
Uncased coils are typically more difficult to install. However, an uncased coil will provide the aforementioned comfort and be just as efficient as a cased scroll when installed properly.
Before the coil tin can be built into the existing sheet metal supply plenum, there is specific preparation required. These requirements are specified by the manufacturer. Failure to follow the installation manual's guidelines may result in damage to the furnace too as the coil.
The drain pan on the gyre is plastic, so track need to be fabricated by the installer to make sure the coil is sitting the proper distance higher up the furnace oestrus exchanger. This keeps the drain pan from melting. If the drain pan melts into the furnace, it could permanently harm the furnace or cause a burn.
One time the rails are built and installed, the coil can exist installed into the supply plenum. If the plenum is larger than the scroll, a sheet metal pan must be built with an opening provided below the whorl. This opening needs to mirror the bottom opening of the ringlet for proper airflow from the furnace going through the roll.
If the opening is not large enough, or as well much air goes around the whorl instead of through it, the whorl will freeze into a block of ice. This can damage the coil and crusade a refrigerant leak by swell the tubing conveying the refrigerant.
Once those are installed, the final step is building the front of the plenum. It is possible to build an admission console door into the plenum to embrace the coil. This is not required past any code or manufacture specification, so it would be up to the installer. In all scenarios, the embrace must have holes provided for the refrigerant lines, and then also for the condensation lines to be connected.
The blazon of coil called is mostly based on the details of the installation. Some won't allow for a cased gyre due to sizing restrictions, for example. Regardless, if the coil is installed per code and manufacture specifications to the existing duct system, can bleed properly, and is sealed from air leaks, y'all will bask the same level of comfort. There is no difference in warranty or life expectancy between either type of coil.
Installation of the New Copper Refrigerant Lines (Line Set)
The new refrigerant line set is a combination of two private copper lines. One line is always bigger than the other and is insulated. The bigger line is chosen the suction line, and the lilliputian one is called the liquid line. They come packaged together, rolled in a coil. It is bachelor in multiple selections of lengths, from xv-50 feet. You will rarely need more than than 50 feet in a residential home.
The key is installing the line with as few bends and turns equally possible. When these bends are necessary, the soft copper tin can exist bent by mitt or a tubing bender.
It's common to install the line set up every bit close to your home'due south beams and ductwork as possible. It'south too recommended that you secure the line every 4-half-dozen feet. Plastic or copper strapping is common. Metal straps or clamps can be used, but it'due south important to protect the copper wiring if the clamps touch them.
If you don't properly protect the line, it can corrode. Galvanic corrosion (also chosen bimetallic corrosion) is the breakdown of metal when 2 dissimilar metals come into contact. This does have some fourth dimension to occur. Withal, if allowed to occur, it could eventually reduce the integrity of the copper refrigerant line over time until it causes a leak.
Later on the hangers are installed, the line set up can at present be put in place. Typically, an installer volition start with the suction line and whorl out one finish a few feet, leaving the balance of the ringlet in a curl. They then button the unrolled department through a pigsty drilled through the band board of the house to the outside, nigh the air conditioner. Enough of the line is pushed out to reach the service valve of the air conditioner.
Somewhen, the installer will connect this line to the air conditioner itself. The hole size volition be between two-2.5" in diameter, depending on the type of line set being used.
Subsequently the line is outside by the air conditioner, the line is secured by hangers near the hole and and so another hanger back a couple of feet. The line is and so carefully uncoiled and formed forth the floor joists up against the torso line ductwork or a beam, as straight as possible until long radius turns or bends are needed. Along the way, it gets put into the hangers that have been installed previously, securing it in place.
The line fix will run from the air conditioner exterior to the new indoor evaporator coil on top 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 set should be new, installed as one piece, free from any precipitous bends or kinks, and secured with an appropriate hanging system.
In that location volition besides be a small, 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 betoken to the air conditioner to turn on and off when a telephone call for cooling is needed or has been satisfied.
Setting the New Air Conditioner Condenser
So far, nosotros've ready the pad, leveled information technology, and our refrigeration lines and electrical disconnect are ready to be wired into the new air conditioner condenser.
Removing the new air conditioner and setting information technology on the pad is step 1. After uncrating the unit of measurement, a skilful installer will 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 information technology arrives and when it's installed, to ensure it is in working order.
If there is a dent, that doesn't necessarily hateful there is any damage that volition impact operation. Nevertheless, you ever have the correct as a customer to non accept the damaged unit and enquire for another ane.
The line set that was installed in the previous step is then formed and fitted to the appropriate service valve on the new air conditioner. The service valve is a connection point for the line fix, and also isolates the refrigerant independent inside the unit. Service valves also permit for the outdoor condenser portion of the air conditioner to be isolated from the indoor coil and line set for futurity service or repair needs when needed.
Isolating the refrigerant keeps you from having to replace it with all new refrigerant in case of a repair in the future.
Later the line set is fitted to the service valves, they must be brazed in. Brazing, a form of welding, is a process using two gases (oxygen and acetylene) and a filler rod made of an alloy metal and argent to join the copper line set and service valves. The valves are heated to a minimum of 1200 degrees Fahrenheit or until the filler rod will flow to weld the connectedness.
If this process is completed properly, the copper line fix, the filler rod, and the service valve are all melted together for a tight, leak-free connection.
Filter Dryer Installation
Filter driers are a key component in the refrigerant organization. They serve two main functions. The most important role of a filter drier is to blot moisture. The second is to provide physical filtration.
When installing a new air conditioner condenser, you must always install a liquid line filter drier into the refrigeration system. Most new air conditioner condensers come with a liquid line filter drier for yous to install.
Manufacturers recommend the filter drier be installed close to the expansion valve (TXV) at the indoor curlicue, as often as possible. This keeps the TXV protected and keeps the filter drier from being exposed to weather where information technology could rust.
There is also an pointer for period management. This arrow must always be in the management that is going into the indoor roll.
Whatsoever contaminants in the refrigeration organization are harmful. Water or wet is the worst.
Wet enters the organization in different ways. If a arrangement is not evacuated properly, moisture will be in information technology. Wet can besides come from leaks or motor windings. The water can cause corrosion and create failure in metallic parts.
Water or moisture can also react with the oil in the refrigerant organization. This is called hydrolysis, which forms acids in the system. Acids, moisture, or any other contagion in the lines will be extremely unsafe to the integrity of your new air conditioning system.
All good HVAC companies have strict processes in place for their install teams to prevent failure as much as possible. Any time a refrigerant line is open to the temper, it is vital to install a new filter drier. This is true of installations likewise as service repairs.
This brazing procedure is the same for connection to the indoor evaporator coil. This, again, involves open up flames and should just be performed by a trained professional.
The gases used in the process are explosive. There is an open flame outside and inside the habitation. It tin can exist dangerous to the installer, the homeowner, and the abode, causing permanent damage without proper training. Following manufacturer and safety guidelines is key.
Preparing the line set for refrigerant in this style is the most important footstep in ensuring the prophylactic and efficiency of your air conditioner.
Sadly, this process is unknown or not followed to most install teams. Not all companies are equal in training or processes, and many contractors lack the proper equipment. A expert HVAC company will take 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 gyre, heat protection needs to be applied. Heat protection can be a heat-arresting paste, wet towels, or rags. Annihilation that would go along the rut spreading into either of the coils is acceptable. The service valves on the outdoor condenser comprise condom O-rings that will melt 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 fix, losing the manufacturing plant charge.
From the factory, the air conditioner condenser is prepared, cleaned, and the refrigerant is added. If the refrigerant is exposed before the process is completed, information technology becomes contaminated, forth with the condenser roll. If this footstep is performed improperly, all the refrigerant would need to be recovered and the condenser curl would demand cleaned and prepared again before any refrigerant could be added.
Most indoor coils accept a metering device called an expansion valve that will be damaged if not protected from the heat during brazing. If these go likewise hot, or any contaminants are introduced, the expansion valve will exist compromised and fail to operate.
Once the heat protection is completed, a tank containing a gas called dry nitrogen is hooked upwards to a regulator and possibly a manifold approximate set. 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 e'er be nowadays immediately.
The HVAC industry requires brazing with nitrogen every time to forestall this damage.
Brazing with nitrogen, when done properly, volition give the system maximum opportunity for performance, reliability, and dependability. After the organisation is brazed in both the indoor and the outdoor components, it must be checked for leaks using the same dry nitrogen, upward to a specific corporeality of pressure. Using the dry nitrogen to pressure test the arrangement achieves three things:
- It's a preliminary leak test.
- The dry out nitrogen will pick upwards moisture.
- It volition also purge some contaminants out of the arrangement upon its release.
It is very important to verify with the installation manual provided past the manufacturer what they recommend for pressure. Most systems are designed for 150 PSI when testing.
If there is too much pressure added, problems can occur. If the pressure is too high for the O-ring seal, for example, the nitrogen will bleed into the refrigerant, contaminating it.
In this scenario, all the refrigerant independent in the condenser from the factory volition be compromised and will have to exist recovered, then the coil cleaned and prepped for more refrigerant.
If the preliminary leak test with nitrogen holds for a minimum of x minutes, then it's time to movement on to the side by side crucial step: vacuuming the system.
Typically a system is vacuumed to a minimum of 500 microns. The manufacturer's recommended vacuum is constitute in the installation manual. Refrigeration systems are designed to operate with only oil and refrigerant flowing through them.
Our temper is made upward of oxygen, nitrogen, and wet. These are enemies to the system's performance and may enter the organization during installation or servicing. Removal of these, forth with air or other non-condensable products, is required. This is accomplished through the vacuum procedure when installing the air conditioner. The vacuum procedure can accept no less than xxx minutes and upward to an hour or more depending on the size of equipment coils and length of line set.
Failure to provide a dry out, moisture-free atmosphere before introducing the refrigerant into the rest of the organisation will in all cases promote an inconsistent operation, and eventually permanent failure of the organization.
To attain 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 organisation and hold the vacuum for this to exist successful. This is besides the second and final leak test. If a system does not hold a vacuum, then there is a leak somewhere.
Once a proper vacuum is achieved and has proven to concur, the organisation is ready to have refrigerant introduced to it. Refrigerant is the only product that tin can "intermission" the vacuum. If hoses are disconnected from the system earlier the refrigerant has been released into the system, the atmosphere will break the vacuum. If this happens, the vacuum process must be redone before refrigerant can be introduced.
With the hoses still continued to the service valves of the air conditioner, the refrigerant is released into the system, breaking the vacuum by opening the suction-side service valve first followed by the liquid side 2nd.
Installation of the New Loftier- and Low-Voltage Wiring
For the air workout system to operate, the high- and low-voltage wiring must be reconnected. Using the existing power supply from the electrical panel inside the domicile, the installer will mount a new service disconnect box. The disconnect is mounted deeply to the side of the house using appropriate fasteners, based on the type of surface it is being mounted to.
In that location are 2 main types of disconnect boxes. Ane is fused and the other is not-fused. They are both appropriate to utilise outdoors. A fused disconnect allows the proper overcurrent protection required by the manufacturer. This type is most common and required when the main circuit from the console exceeds the maximum required overcurrent protection. It too allows for additional safety to the air conditioner condenser.
A non-fused disconnect may be 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. Yous must be within these guidelines. The organisation will not pass the code requirements if they are not.
For example, if you have an existing 40-amp circuit that supplies the disconnect, but the listed overcurrent protection is only 30 amps, you must use the fused disconnect and install 30-amp fuses with information technology to properly protect the ac condenser. If the amperage from the billow 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 ability to become to the air conditioner itself through the electric whip. They are identified as "Line" (wiring from the electrical panel) and "Load" (the whip that takes power to the air conditioner). This allows the pull inside the service disconnect to pause or disconnect the power supply to the air conditioner without having to shut the breaker off from the main console.
Considering the air conditioner is exterior, information technology would be cumbersome to run in and out of the firm to turn the ability on or off in case of emergency or servicing. The service disconnect is required by land and local code requirements.
There are likewise requirements for placement of the air conditioning condenser. It boils downwards to making sure there is proper accessibility. All the electrical connections should be made according to the NEC (National Electrical Code). The low-voltage control wire is connected directly into the air conditioning condenser at the proper locations co-ordinate to the air workout condenser installation instructions.
This is the "bespeak" from the control board in the furnace sent through the wire to the air conditioner when the thermostat calls for cooling. The low-voltage control wire is what allows the air conditioner to bike according to the parameters set up regarding temperature and humidity inside the domicile. The low voltage wiring is connected to the control board inside the furnace on designated terminals.
Installation of the Condensate Bleed Line
The moisture removed from the home during the cooling procedure travels downward a plastic PVC pipage. It must be connected to the primary side of the evaporator scroll. The evaporator coil has a primary and a secondary drain location. The primary condensate drain line will travel from the indoor evaporator coil to an advisable floor bleed or condensation pump.
A condensation pump is used where a proper flooring drain does not exist in the home. In that location are also other reasons where a condensate pump is required or is beneficial to install. The important thing to remember if a condensate pump is used is that it must exist serviced a minimum of twice a twelvemonth to maintain proper performance.
Whatever condensate tubing or piping should be secured and glued with the proper cement. A trap and an overflow prophylactic switch must besides exist installed in the condensate system. This is to protect the equipment and the surface area from flooding due to a restriction. The safety overflow switch is connected to the secondary port on the indoor evaporator ringlet and wired into the furnace control to shut down the system when it is tripped.
Startup Commissioning Procedure
The startup and commissioning (testing) process is done later on the system is completely installed and ready to operate. The arrangement is turned on and must run for 15-20 minutes. This will allow the refrigerant to catamenia through the organisation and beginning the ac process.
Upon initial startup of the new air conditioning system, the business firm should be very warm or have a "load" with a warm enough temperature inside the home to allow for the minimum potential to charge the organization accurately. A temperature higher up 75 degrees Fahrenheit is recommended in most cases. This allows the components in the air conditioning arrangement to be in total operation to permit maximum cooling potential during charging.
Sometimes running the furnace to estrus the business firm is a mutual practise to provide the necessary load on the dwelling. After 15-20 minutes of operation, the arrangement tin can now be deputed.
A practiced installer volition check the thermostat operation, arrangement sequence of operation, and multiple other areas. While the system is operating, the following data is of import 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 bulb temperature
- Indoor wet bulb temperature
- Return air temperature
- Supply air temperature
- Static pressure level from return side, supply-side, and total static readings
- Temperature drop calculated
- High voltage current reading
- Amperage on the blower motor, outdoor fan motor, and compressor
- Depression voltage electric current reading
- Line set length
- Amount of refrigerant, if whatsoever, added to the system
- Altitude above or below the outdoor unit is in relation to the indoor curlicue
- Blower speed tap/CFM recorded
This is the bones list of the proper data that should be known and recorded. This is the only way to know for sure how the organisation is operating and if information technology is within manufacturing specifications. If any of these exercise not autumn within manufacturer specifications, your system may not be warrantied by the manufacturer.
Commissioning is of import for several reasons. For you lot, the peace of mind that y'all are receiving a properly set and adjusted system for maximum condolement, efficiency, and dependability. Information technology also ensures the manufacturer's warranty will be in full effect. The benefit to the company installing the organization is that it gives a baseline of operational performance in example any issues arise later.
It also gives the installing team confidence that before they leave, your system is in perfect performance. It is very common for systems to be installed and started up without much consideration for proper commissioning.
Unfortunately, many companies turn information technology on and walk away the moment cold air is coming through the vents.
Proper commissioning is a specific process that requires training and special equipment to perform the process correctly. Information technology also requires additional time and labor on a job site. Commissioning is the just fashion to know for sure exactly how well your system is operating.
Why would a company skip this step, so? In a word: cost. Skipping this procedure costs a company less, which in turn might lower your initial investment slightly. This is a long-term run a risk, though, with your money, your safety, and your condolement.
A good HVAC contractor will have trained installation teams that will properly committee your air conditioner before they leave the job.
Clean upwards and Closing Process
The cleanup process is comparatively simple. All fabric and erstwhile equipment should be loaded up and taken away from the home. The floor protection should be rolled up last, keeping all debris from the installation inside the drib material and out of your domicile.
All areas should be swept and free of any materials or debris. You should expect to see the surface area in the same status in which it was institute.
A walkthrough of what was washed during the installation should exist completed with you. Going over rubber, maintenance, warranty, and all special instructions are expected.
As a final mechanical step, a locking cap should be placed on the outdoor portion of the unit. This cap can only be unlocked with the correct fundamental. This is to prevent tampering with your equipment, and also to forbid theft of the refrigerant. This cap is frequently a specific colour, which volition let a technician know which type of refrigerant your organisation uses.
A visual inspection of the work completed should likewise be offered. Finally, a review of the commissioning and thermostat operation. After the final walkthrough, terminal signatures and payments are collected.
Installation Completed Professionally
The job is now complete!
The procedure may seem long and complicated, simply in the hands of a skilled installation team, the entire process should be second nature.
Don't cut corners with installation. Your coin and comfort are at risk if any of these steps are skipped. Knowing the full procedure will allow you to hold companies accountable when you make up one's mind to invest in a new air-conditioning system. The issue volition be a comfortable, efficient, long-lasting product.
