Routine Air Conditioning Maintenance Can Prevent Costly AC Repair

By Melissa Wilson


When the warmer days of spring arrive, residents know they only have a few weeks before they need to turn on their air conditioning to remain comfortable in a home. Just like with an automobile, regular maintenance for these cooling systems is the best way to keep them working correctly. Maintenance can prevent much more expensive needs for AC repair.

Operating dirty systems can stop air from flowing through the cooling coils and result in a warm house. Dirty coils cause other components to work more to maintain the temperature set at the thermostat. The additional strain may eventually cause premature failure of the air conditioner.

Air conditioners use coolant that is commonly called Freon to transfer heat. If the Freon levels are low, systems become less efficient and must work much harder. Eventually, they might not cool at all. In addition, these low coolant levels may cause the compressor to freeze and be permanently damaged.

Each time the AC system turns on the electrical contacts make a small arc, which can over time, cause the contacts to become pitted. Eventually, this little switch no longer makes proper contact, causing the air conditioning to fail to function as it should. In some cases, the pitting can cause the cooling system to no longer cool at all.

The air handler for the system is connected to the various rooms it cools through ducts. Leaks in the ducts allow warm air from the attic or other spaces that are not cooled to be pulled into the device. This lowers the efficiency of the system and increases the dust and particulate matter that must be removed from the air.

One of the keys to prevent ac repair is regular maintenance. Small problems can be discovered and fixed before the unit fails. Having the unit inspected and maintained is a key to efficient operation.
