Symptoms of a Dirty Coil

We often tell our customers that cleanliness equals longevity when it comes to remaining energy efficient during the cooling season. In addition to cleaning and changing the air filter, the evaporator coil is another critical component that must be regularly cleaned. The following signs suggest the need to have your evaporator coil professionally cleaned.

Your Home Remains Warm When Running the AC

An air conditioner that blows out warm air is likely to be the first sign you notice if you have a dirty coil. When dirt collects on the coil, your air conditioner’s ability to remove heat from the air can be substantially limited. To avoid buildup collecting on your evaporator coil, we recommend:

  • Evaporator coil cleaning
  • Air filter cleaning/replacement
  • Duct cleaning

Your Evaporator Coil Freezes

A frozen coil is the direct result of dust and debris accumulating over time. When a dust-covered evaporator coil is no longer effective at drawing heat from the air, condensation may accumulate on the coil. If the condensation freezes, you should immediately turn your air conditioner off and contact a licensed HVAC technician in Kirkland.

Your System Is Working Harder Than Usual

Because a dirty coil can’t effectively remove heat from the air, your system will work harder, which ultimately places more wear and tear on its parts. If left unattended, your system will likely break down and require repair.

Your Energy Bill Increases

Long before a dirty coil causes mechanical breakdown, you will also likely notice an increase in your energy bill. Accumulated dust causes your system to work harder and consume more energy. The extra energy consumption will increase your bill.
