It’s the time of year in southwest Oklahoma when homeowners should be scheduling their annual air conditioner maintenance. An HVAC technician will check the refrigerant charge, capacitor, airflow, controls, thermostat and electrical settings. However, there are tasks a homeowner can perform on the A/C prior to the arrival of the licensed professional.
Clear Away Debris
Clear all leaves, grass clippings and other debris around the outdoor condenser and compressor. Make sure there’s at least a two-foot area around the compressor that’s clear of weeds, shrubs and clutter.
Check the Coils
After turning off the switch to the outdoor unit, open up the housing to gain access to the condenser. If the condenser coil, which is a series of copper tubes in an aluminum framework, appears dirty, clean it by spraying on foaming cleanser or by spraying it lightly with a garden hose. Using a fin comb, straighten bent aluminum fins. You can also check the indoor evaporator coil. Usually you will have to remove an access panel to get to it. The evaporator coil may be an A-shaped aluminum framework with copper tubing inside. Clean it with foaming condenser cleanser, which will drain away.
Check the condensate drain (it’s in the inside unit of the A/C). This is where condensation from the evaporator coil drains away. Make sure it is unplugged by running a wire through the channels to break up clogs. Check the drain pan to make sure there are no holes.
Change the Filter
A clean filter is a must for your A/C. If you don’t already change the filter every month, then start today. Use a good quality pleated filter. If you use washable filters, make sure they are clean.
Don’t skip your annual maintenance. By replacing worn-out parts or making sure controls, settings and measurements are set as they should be, you’ll reduce wear on your system and it will last much longer.
