Air Conditioner Maintenance Affects Whole-House Performance

Posted by Paul Wadsworth on Mon, May 14, 2012 @ 01:09 PM

The simplest, most cost-effective way to make sure you're getting the most out of your air conditioner is by scheduling routine maintenance. Regularly scheduled professional air conditioner maintenance, along with some easy homeowner-done upkeep tasks, will make sure your home comfort system works efficiently and well — saving you money and keeping your home comfortable.

Maintenance also extends the life of the heating and cooling equipment in your greater-Cleveland-area home, delaying the cost and inconvenience of replacing the system in the future.

Homeowners can keep their air conditioning systems in top shape between professional visits by:

  • Replacing the air filter monthly or whenever it appears dirty.
  • Keeping vents clear of rugs and furniture.
  • Cleaning the outside A/C condenser unit with a water hose as needed. NOTE: Make sure to kill the power to the unit before attempting this task and then remember to turn it on again when finished!
  • Making sure lawn clippings and shrubs are cleared away from the unit.

Schedule a maintenance visit from your local HVAC expert in spring, to prepare your system for upcoming heavy use in summer.

Your technician will provide a thorough inspection and take care of these tasks:

  • Test controls, electrical wiring and connections.
  • Check refrigerant level, adjusting if necessary.
  • Clean any debris from inside the cabinet (outdoors).
  • Clear any obstructions from the outside drain.
  • Inspect coil, fan motor and blades, lubricating if necessary.
  • Clean evaporator coil, drain pan and lines.
  • Examine compressor and tubing for leaks.
  • Clean blower housing.
  • Lubricate and clean motor.
  • Replace fan belt if worn.
  • Replace/clean air filter.
  • Inspect the duct system, checking for leaks or debris buildup.

Air conditioner maintenance while the A/C is running:

  • Monitor system start-up.
  • Investigate any excess noise or odor.
  • Measure refrigerant pressure.
  • Adjust air circulation rate as needed.
  • Check vents for obstructions if indicated.
  • Test electrical system.
  • Provide a system condition report, noting any needed repairs or parts.
