3 Common Evaporator Unit Problems

The standard “split” central air conditioning system consists of two units: The outdoor unit is known as the condenser, where the AC releases and vents heat to the outside air. The condenser also contains the vital component of the compressor. The indoor unit is called the evaporator, where the evaporator coil absorbs heat from the air, and a blower fan sends it into the ventilation system to the rooms of the house.

The evaporator unit can run into a number of problems that will reduce the cooling ability of the AC and impair its airflow, possibly leading to a full breakdown. Should you notice any trouble with your air conditioner’s operation, contact a company like ACI Northwest immediately and let our trained technicians handle the issue. For more than 85 years, we have delivered excellent air conditioning repairs in Spokane, WA that has kept customers returning to us.

Three of the More Common Evaporator Unit Problems

  1. Ice on the evaporator coil: People often shrug off the appearance of a layer of frost along the indoor coil because they assume it’s a natural part of the cooling process. But any ice on the evaporator coil means serious trouble occurring within the system. It could be a refrigerant leak, a clogged air filter, or grime across the coil. Call for technicians to look into the trouble immediately to discover what is wrong, fix it, and then defrost the coil. If left without repair, the ice will continue to grow until it blocks the coil from performing heat exchange.
  2. Blower motor malfunction: The blower fan is essential both for sending conditioned air into the ventilation system and for running warm air across the evaporator coil to remove its heat. If the blower fan motor starts to fail due to wear, loss of lubrication, or electrical issues, it could cause the blower to stop entirely and prevent the AC from cooling. Major mechanical issues like this always require a technician to fix.
  3. Clogged air filter: The evaporator unit draws air into it through the return vents, and these vents can carry large amounts of dust, dander, and fibers that may damage the interior of the AC. To prevent these contaminants from entering the evaporator, an air filter traps the particles. But unless the air filter is changed regularly, it will become clogged and eventually begin to impede airflow into the system, leading to excess strain and higher AC bills. Make sure to change the filter once a month during air conditioning season, and call for technicians if a clogged filter has triggered a malfunction inside the AC.

Aside from routinely changing the filter, do not attempt to repair an AC on your own. Always call for professionally trained air conditioning repair in Spokane, WA from an experienced company with a long history.
