Home Maintenance & Efficient AC Performance for Air Conditioner Columbus, Ohio

Your Home Air Conditioner Maintenance

Home air conditioner maintenance will not only help in lowering your energy bill, but will also extend the life of your AC unit. It will also save you from costly repairs with just more diligent care of your AC. Before doing any preventive maintenance, remember to shut off electrical supply to your unit. This will ensure safety when working around the air conditioner’s moving parts.

Air Conditioner Filters

Filters Home Air Conditioner MaintenanceYou should change filters, or clean reusable filters, at least twice a year.  Ideally, this should be once before the cooling season begins and then before the heating season as well. Having dirty filters make your AC unit work harder since this reduces air flow and thus lower its efficiency.  If your location is in a dusty, populated area, you may need to change or clean your filter more often. A regular, monthly inspection of your AC’s filters will give you an idea whether you need cleaning or replacement twice a year or every two months. See a related article in preventative maintenance.

Condenser and Evaporator Coils

The filters help prevent dust, dirt, and debris from getting into your AC unit.  However, your AC’s condenser and evaporator coils will still gather dust over months and years of service.  The outdoor condenser unit collects dust and debris because a central fan sucks air from around it. This pulls dust all sorts of debris such as dead grass, dead leaves, and those floating “cotton” from dandelions and cottonwood trees.

With all these blocking the air flow into your unit, it lowers your AC’s cooling efficiency.  You can further help your unit by cleaning debris around the condenser and cutting foliage by at least 2 feet to allow enough air circulation around the condenser. Keeping the coils clean will help in the cooling efficiency and years of service of your AC.

Coil Fins

The coil fins are the fine metallic blades on the coils. These are fragile and can bend easily, and thus block air flow.  In such a case, there is a tool easily available in hardware stores called the “fin comb” which will straighten them back to nearly original condition.

Regular Check Up of Your AC Professional

Other than the ones mentioned above, there are some tasks that only your AC professional can do. Checking the refrigerant level is one.  Regular home air conditioner maintenance by your licensed AC technician will help in maintaining the efficiency and prolonging the years of service of your unit.



Tips to Avoid Costly Service Calls

Before Any Service Calls:

  • Be sure that the thermostat is in the correct position. We run numerous service calls every year when the season changes where the thermostat is set in the wrong position. For example, they may have it set for cool, and the air conditioner hasn’t been running because the house has been relatively cool. They then turn up the set point, expecting the furnace to come on. If it’s still in the “cooling” mode, the furnace will not come on. Also, make sure that the thermostat is at a temperature that’s higher than it is currently reading.
  • Check your furnace filter. If it’s dirty, it will cause a limit in the furnace to trip, causing a situation where you’ll have no heat. If you find that it’s dirty, remove and replace it, turn the furnace off at the breaker, leave it off for 30 minutes, and then turn it back on. This should re-set it.
  • Check circuit breakers. If the breaker trips, the furnace won’t come on. Even if it doesn’t appear to be tripped, it doesn’t hurt to reset it if you’re having a problem with the furnace.
  • Be sure that the bottom door of the furnace is on properly. There is a built-in door switch that won’t allow the furnace to operate if it’s not on correctly.
  • If you have a heat pump, keep if free of snow buildup. This may cause the unit to defrost improperly in the heating cycle.
  • On a side note, make sure that you check your carbon monoxide detectors and smoke detectors at least annually!
  • It is always a good idea to have your furnace checked annually for safety, by a licensed professional. This will help to ensure that it’s running at peak efficiency and it will keep any applicable manufacturer’s warranties in effect.
