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
You 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.
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.
