An inefficient air conditioner can become very expensive to run. Many people think that their AC is no longer working just because it is too old. However, there are other factors in an HVAC system that can also decrease the efficiency of your AC unit. These small problems are usually things that you can fix on your own. With a few simple maintenance and cleaning tasks, you can greatly improve your AC system. Here are a few things you can do on your own time, without any special tools.
Clean your Condenser Coils
The condenser coils are the aluminum ridges that line the outside of the AC unit. They are usually protected by the unit's cage. The cage protects the coils and prevents them from getting damaged. However, the coils can still get dirty and clogged. Wind can blow leaves, dust, dirt, and other debris into the coils. If the coils are clogged, the AC unit will have a difficult time sucking air into the unit. With less air being sucked into the unit, your AC will not be able to blow out as much cold air. Clogged coils are a common reason for reduced air flow and improperly cooled air.
To clean your condenser coils you should first unplug the power supply. Then, just spray down the coils with a hose. Don't spray them with too much pressure because it could bend the coils. And, definitely don't use a pressure washer! Wait a few hours for your unit to dry before you plug it back in and test it.
Clean the Air Registers
Some people dust off their air registers on a regular basis. However, this usually just pushes the dust into the duct system. To properly clean your registers, you should remove them from the wall first. Remove the screws with a flathead screwdriver and clean the backside of the vents. A wet rag is usually enough to get the job done, but you might need to clean between the vents with a rag or dusting feather. If the vents are adjustable, you should move them around a bit while you are cleaning them. You want to make sure there is no dust in the hinges.
With clean air registers and condenser coils your AC unit will be much more efficient. You can save money on your bills and enjoy a cooler home during the hot summer months. For assistance, talk to an air conditioning repair professional.
