If you live in Phoenix, it can be difficult maintaining low cooling costs. However, there are some things you can do to enhance your home’s comfort while remaining energy-efficient. One highly important component of your semi-annual maintenance is having your HVAC technician clean your air conditioner’s evaporator coils.

Even though you do not normally see them, evaporator coils are crucial components of your home’s cooling system. They are located inside your air conditioner, and they are essential to the equipment’s ability to create cool air.

Your air conditioning system  works like this:

  • Refrigerant is compressed by the compressor, then delivered to the outdoor condenser which converts it from a hot gas into a high-temperature liquid.
  • The liquid is delivered to the evaporator coil while a fan draws air across the coil. When the warm air is passed over the low-temperature evaporator coils, heat is removed from the air. This causes the liquid within the coils to return to a gaseous state.
  • The air which has been cooled is delivered into your home through the duct system.
  • The refrigerant gas is returned back to the compressor and the process repeats itself.

When you understand this process, it becomes evident that the evaporator coil is a major component of your home’s air conditioning system that is responsible for cooling the air. The process of moving air over the coils causes dirt and dust to be deposited on the coil. As a result, efficiency is reduced which means that your unit needs to work harder. This translates into an increase in your utility bills.

The outdoor condenser can be cleaned easily with a common garden hose, but it is more difficult to access the evaporator coil for cleaning. For this reason, a licensed professional should be utilized to ensure that the cleaning is done properly performed. Your current HVAC contractor may not include this cleaning as a part of the regular maintenance, so the recommendation is to ask.
