Air Conditioner Cleaning in St. Louis

Air conditioner cleaning in St. Louis by a qualified HVAC technician directly impacts the operating costs, cooling performance and expected service life of your central AC. When your air conditioner was new, it came with manufacturer’s specifications that express the designed energy efficiency and expected performance of the unit. These figures, however, are all based on the assumption of regular maintenance including air conditioner cleaning by a professional.

It’s best to schedule your St. Louis air conditioning cleaning services in the springtime before the heat and humidity returns and you need your AC unit to cool your home.

Our Air Conditioner Cleaning Process for St. Louis Homes

Here’s why AC cleaning is critical to restore your system to manufacturer’s specs and ensure both household comfort and efficiency.

Evaporator Coil

Sealed inside the indoor air handler, the evaporator coil extracts heat from household air. The entire air volume in your house circulates through the evaporator coil multiple times each day. Airborne dust, lint and even microorganisms like mold spores accumulate on coil surfaces. A dirty evaporator coil triggers a variety of A/C dysfunctions, up to and including total system failure.

  • Dirt reduces coil heat extraction.  The air conditioner runs longer cycles to produce cooling and monthly utility bills increase.
  • A dirty coil cools less effectively, impacting household comfort, particularly on hot summer days.
  • As airflow and heat extraction decrease, a dirty coil may drop below the freezing point and ice may form. Coil icing may totally obstruct airflow and trigger a system shutdown.
  • Extended “on” cycles over-stresses system components, leading to early failure.
  • A dirty evaporator coil is a breeding ground for mold and other bacteria, circulating toxic spores into household airflow.

Condensate Drip Pan

On a humid summer day here in Missouri, a central air conditioner can produce over 20 gallons of condensate per day. Situated beneath the indoor air handler, the drip pan collects and diverts A/C condensate down a drain line.  If dirt, algae growth or other debris clogs the pan or drain, overflow happens rapidly. Water damage to the structure of the house and/or belongings may result. A qualified air conditioner technician will clean the pan, install time-release biocide tablets to prevent algae or mold and verify that the condensate drain line is open.

Condenser Coil

Located behind or beside your house, the condenser coil disperses heat extracted inside the house.  Exposed to outdoor elements, condenser coil surfaces get dusty. Leaves, grass clippings and other debris may also infiltrate the unit.

  • A dirty condenser coil disperses heat less effectively.  A coil covered with as little as 0.040 inch of dust or dirt can typically reduce system cooling performance by over 20%.
  • Energy efficiency declines and the monthly expense of keeping the home cool rises.
  • Expected service life of air conditioner components is shortened. The compressor—the most expensive part in the system—may overheat and fail.
