Preventative Maintenance For A Central Air Conditioner

Posted on: 7 December 2016

Do you constantly have to spend money on repairs to keep your central air conditioning system working in a satisfactory manner? If you are ready to go longer periods without the need for the system being repaired, investing in professional maintenance on occasion might resolve the problem. Unless you simply have an old system that is about to go out altogether, preventative maintenance is a wise investment. This article will give you an idea about the most important types of maintenance that should be done for better operation from the air conditioning system.

Get the Air Handler Inspected

The air handler is important for a central air conditioning system to function to the fullest extent. You won't even feel air in your house from the system if the handler is out of order. It is wise to get the fan in the handler inspected sometimes to make sure it is able to rotate. Sometimes cleaning or lubing the fan up is needed to keep it in good shape. Make sure maintenance is done for the motor in the air handler as well, such as by getting it inspected for rust and wear.

Don't Allow Dirt to Accumulate

You should never allow your central air conditioning system to accumulate large amounts of dirt. You can end up with many areas of the system not being able to do their job. For example, if there is a large amount of dirt in the duct system, air might not be able to fully flow out of the vents. When dirt is in the air handler, it can cause the motor to stall or become less powerful. Dirt on the fan can reduce the amount of air being produced, which causes the system to not be energy efficient.

Make Sure the Evaporator Coil Works

The evaporator coil is the most important part that should receive occasional maintenance from a professional. You must understand that the coil is necessary because it is how the system is able to cool down warm air. The coil must be without rust or debris in order for it to perform as it should. Basically, it must be possible for warm air to make full contact with the metal on the coil in order to cool down. Keep in mind that an evaporator coil is able to become extremely cold from coolant, which is why it can cool down the warm air that passes through and touches it.
