How to Replace Evaporator Coil in the Air Conditioner?

The evaporator coil is found in the heat exchanger unit. It is an inside part of the air conditioner and a major component of the air conditioner. The evaporator coil contains the refrigerant. It is made with copper or steel material. 

How does the evaporator coil work in an air conditioner?

The air conditioner unit pulls the warm air from an enclosed area, and the warm air is transferred to the evaporator coil. Hot liquid refrigerant interacts with warm air particles, and warm air is converted into cool air. This process happens in the evaporator coil. Cool air passes towards the blower fan unit. A blower fan transfers the cool air inside your room. 

Why does the evaporator coil fail?

1. Frozen evaporator coils: Damaged or Dirty air filters: Dirt, dust, and other particles are stuck in between the air filter holes. This dust creates a clog in the air filters. Dirty filters create many problems in any heating, ventilation, and cooling equipment parts. Replace your damaged air filters. PartsHnC delivers the best quality air filter at a reasonable price.
2. Less amount of airflow: The evaporation coil needs enough warm air to absorb warmness from the air. Because of less air condensation on the evaporator coil, it freezes the coil. 
3. Dirty Evaporator Coils: When the evaporator fills with dirt or debris, obstacles are created in the heat exchange process. The dirty evaporator coil is unable to absorb the heat from the warm air properly.
4. Low/ High refrigerant amount: Less amount of refrigerant puts a load on the heat exchange process. It may freeze your evaporator coil.
5. Low outside temperature: Cold temperature freezes the evaporator coil. In cold temperatures, the air is cool, but less warm air freezes the evaporator coil.
6. Clog in drain pipe: Do not worry about the clog development in the drain pipe. Clean the clog. The clog is made in the drainpipe because of the condensation process. 
7. Dirt in condenser coil: The condenser is the outdoor part of an air conditioner, and it directly contacts the dust, dirt, debris, and other particles. The fan motor expels the heat of the refrigerant and collects cool air inside the condenser unit. A dirty condenser coil may indirectly create problems in the evaporator coil.
8. Refrigerant leaks: Refrigerant leakage means wastage of refrigerant. A low level of the refrigerant increases the load on an evaporator coil. 

What are the signs of a failed air conditioner evaporator coil?

• Warm air is coming from air conditioner vents.
• Ice build-up in the evaporator coil.
• Reduced heat transferring capacity.
• Reduced the cooling capacity of an air conditioner. 
• Your air conditioner continuously starts and then stops or does not completely start.
• Refrigerant leakage in the air conditioner.
• Suddenly, the air conditioner consumes high energy.
• The air conditioner creates unusual noises like hissing or banging.

How to replace the evaporator coil?

• Switch off the power supply of the air conditioner.
• Switch off the power refrigerant liquid line of the air compressor.
• Do not change the evaporator coil without the HVAC technical experience. 
• Replacing an Evaporator Coil is tough for a single person. So, take the help of someone.
• Disconnect the exit and inbound tubes.
• Aware of the gas leakage. 
• Dispose of refrigerant gas carefully. If you do not know about refrigerant gas disposal, then take the help of an HVAC expert. 
• Replace the old evaporator coil with a new one. Buy the best quality evaporator coil at the lowest price range from the PartsHnC website.
• Clean the refrigerant lines with the help of a vacuum machine. After cleaning, Fill the refrigerant on the top level. See the manual to determine how much refrigerant is needed for your evaporator coil.
• Start the power connection.
• Observe if your air conditioner works properly or not
• If your air conditioner creates any unusual noise, produces a different smell, or does not work properly, then turn off the air conditioner and call a technician.
• If it is working properly, then you do not need to replace your evaporator coil for up to 10 years.
• Proper maintenance of your HVAC system extends its life.

How to clean the evaporator coil?

• Spray the air in the opposite direction of normal airflow.
• If some dirt is not cleaned with compressed air, put your air nozzle close to the soil and clean it with high pressure. 
• But take care of the evaporator coil. High-pressure air may damage your evaporator coil.
• You can use a smooth brush to clean dust, dirt, or debris. 
• Or use water and mild detergent to clean up the evaporator coil.
