Spring is the ideal time to tune up that home central air-conditioning unit. A little time and money spent early can help avoid major repairs during the summer when that A/C unit must be a workhorse. Many companies like Atlanta AC Maintenance offer affordable packages for this type of service. For the do-it-yourselfer, here are some additional air-conditioning unit maintenance tips.
· Check the Freon level. Chances are your air conditioning unit should never need Freon filling or changing. If the Freon level is low t is indicative of a leak in the system. Most newer air conditioning systems have welded system connections, which minimize leaks. Older units that have flared fittings can develop leak caused by vibrations as a result of the units normal operation. These leaks should be repaired before adding new Freon. Low Freon levels can reduce the unit efficiency, freeze the evaporator coil or cause the compressor to overheat.
· Check all the electrical components, controls and connections.
· Clean the evaporator of dust, leaves and other foreign matter
· Also, remove any foreign matter from the condenser coils.
· Check the condenser operation.
· Check, clean and replace filters as needed.
· Oil electrical motors as necessary.
· Calibrate the thermostat for proper operation.
· Make sure the area around the central unit is clear. The air conditioning unit needs to draw air into it to properly cool your house. If you have lawn furniture or other summer equipment stored near the central air unit it should be removed to insure proper operation of the air conditioner.
· Check to ensure that all access panels are in place and properly secured.
· Give the air conditioner a test run early in the season so if there are problems, you’ll be able to repair them before the weather becomes unbearable.
· Check the thermostat for proper operation and make sure it is set to the cool mode.
· Inspect the heat exchanger for cracks.
Following these tips early in the spring can help to reduce the risk of a breakdown and an expensive repair and can help to prevent your house from a loss of cooling during the hot summer season.
Follow these basic tips and your ac unit will be running properly for many years to come. For even more tips on maintaining your heating and cooling unit, check out the Heating and Air Guide.
