Where is the evaporator coil located on a split system?

Located inside the blower compartment or air handler, the evaporator coil holds the chilled refrigerant that the compressor moves into it. As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from your home’s air.

How do I change an AC evaporator coil?

While we suggest hiring a professional to replace evaporator coils, here’s an idea of what you can expect, if you want to try it yourself.

Park any remaining Freon in your air compressor.
Cut off compressor.
Cut tubing.
Remove the old evaporator coil.
Install new evaporator coil.
Braze the lines.

Is the evaporator coil the same as the A coil?

The condenser coil is of similar design to the indoor evaporator coil. However, the difference between A/C evaporator and condenser coil is exactly reversed. While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air.

Can an AC evaporator coil be repaired?

What is the Process of Replacing the Coil? In order to replace the coil and fix your evaporator coil leak, a technician will need to recover the remaining refrigerant gas, and solder in a new coil after dismantling the air conditioner. A filter / drier must also be added or replaced to absorb moister and contaminants.

How do I know if my AC coil is dirty?

Symptoms of a Dirty Coil

Air Conditioning Loses Cooling Capacity. One thing that will be noticeable when the evaporator coil is dirty is that your AC won’t produce air that’s as cold as it should be.
Air Conditioning Runs Longer.
Coil Develops Frost During Operation.
Have an HVAC Professional Clean Your Coils.

Where does the evaporator coil go in an AC unit?

If your air conditioner is going to have a refrigerant leak, there’s a good chance it will happen on the indoor coil. Also known as the evaporator coil, this air conditioner component lives inside your HVAC system’s indoor unit.

How does the expansion valve in an AC evaporator work?

The expansion valve plays a very important role, as it reduces the pressure of the refrigerant. During this process the liquid is cooled, which allows it to absorb the heat and thus cool the air. The blower fan draws hot air from your house over the evaporator coil. As the air passes over, the refrigerant within the copper tubing absorbs the heat.

Is it possible to replace an evaporator coil?

You should probably replace your air conditioner. As we’ve explored before, R-22 refrigerant is scarce, expensive, and practically obsolete at this point. While it’s usually possible to replace an evaporator coil in an R-22 system, it’s typically not in your best financial interest.

What causes condensation to freeze on an evaporator coil?

Without adequate airflow blowing over the evaporator coil, the condensation on the coil will freeze because there isn’t enough heat to be absorbed. Clogged Air Filter – Air filters are designed to filter out the dust and debris from the air as it passes through your system.

How to connect multiple evaporator coils in a single split?

Once the coil is in place, screw it into position tightly by turning the connection with your wrench. Make sure that you have all of the necessary wires on the outside of the coil. You will now need to take the coil, and connect it up to the main evaporator coil.

How does an evaporator coil work in a heat exchanger?

The evaporator coil is filled with refrigerant. As the HVAC blower draws air from inside your home across the coil, the refrigerant evaporates as it absorbs the heat from the air. The coil is a heat exchanger, giving you hot or cold air depending on the time of year.

Why do you need an evaporator coil in Your House?

The evaporator coil is filled with refrigerant. As your HVAC system draws air from inside your home across the coil, the refrigerant evaporates it and absorbs the heat from the air. During the summer months, the coil gives you cool air and serves as a dehumidifier, getting rid of any unnecessary moisture from the air.
