Did you know that the air conditioner in your Fletcher, NC home doesn’t actually produce cold air? Instead, it uses refrigerant to absorb heat from the air inside your home and then distributes the air – that was cooled by releasing heat – back into your house. The evaporator coil is the vital component of your HVAC system where heat is absorbed and released.

Evaporator Coil Vs. Condenser Coil

The evaporator coil is one of two coils in your HVAC system. The other is the condenser coil. These two coils work together to remove heat from your home. Simply put, your HVAC system sends refrigerant to the evaporator coil to remove heat and humidity from the air. The refrigerant is then sent back outside to the condenser coil. From there, the refrigerant is cooled and sent back to the evaporator coil. This cycle repeats itself every time you use your air conditioner.

Maintenance

Evaporator coils must be well maintained to efficiently cool your home. When outdoor air is drawn inside, dirt and debris sometimes come, too. This debris can collect on the evaporator coil and make it harder for the coil to remove heat and humidity from the air. A technician will clean the coil to help prevent this problem during your annual maintenance visit.

Design

You’ll find your HVAC unit’s evaporator coil inside your home close to your air handler. The coil is made from aluminum, copper, or steel because these metals conduct heat well. The evaporator coil is protected by fins that allow air to pass through.

Repairs

Like any piece of machinery, your evaporator coil may need to be repaired occasionally. Condensation is more likely to accumulate on a dirty coil and freeze. A frozen evaporator coil can cause your system to overheat. Regular servicing and changing your filter are the best ways to prevent this from happening.
