Air conditioners require yearly maintenance to stay operating in tip-top condition. Professional maintenance helps ensure that your heating and air conditioning system will continue to run economically and dependably for years.

 
There is very little doubt that an HVAC system consumes a large amount of a home’s monthly energy use. It is estimated that an air conditioner loses 5 percent of its energy efficiency per year if it does not receive regular maintenance. The Environmental Protection Agency (EPA) states that having your unit’s dirty filter replaced lowers the air conditioner’s energy consumption by 5 to 15 percent.

 
The coils of an air conditioner naturally collect dirt. The collection of debris on the unit’s coils obstructs airflow. The debris further reduces the coil’s ability to absorb heat. During regular maintenance, the debris and dirt are cleaned away.

 
Outdoor condenser coils — especially in dusty areas of the country — become dirty quickly. During a professional HVAC maintenance, the outdoor condenser coils are cleaned. You can also further help prevent debris from falling into the unit by cutting back any foliage around the unit. Ideally there should be no vegetation near the unit so it can receive adequate airflow. Keep landscape trimmed back at least two feet from the unit’s exterior.

 
During a professional air conditioning maintenance, an HVAC technician checks the unit’s coil fins to make sure they are not bent or chipped. They will also clean out the condensate drains.

 
Ideally you should have your HVAC system serviced twice a year — in the spring and fall. In addition to the key maintenance requirements listed above, an HVAC technician measures the unit’s amount of refrigerant and looks for any leaks. If a leak is detected, he will seal the leakage. He also measures the airflow through the evaporator coil to ensure that the unit is functioning properly. All electric terminals will be checked, the motor oiled and belts inspected for wear.

 
Regular air conditioning maintenance helps the HVAC unit recover lost efficiency and may save valuable energy consumption. If your system needs some maintenance, give us a call – we’re happy to help!

    This is some really helpful information for any homeowner with an AC system they are interested in keeping. Far too many people ignore their HVAC systems until they are already broken, which could easily be avoided most of the time with regular maintenance by a professional. I agree that twice a year is a safe regularity with which to have your system serviced, just before you start heavily using either the heating or cooling part of the system. Thanks so much for writing!

    Losing 5% a year on efficiency can add up, and 5% will show up on your bills. I agree that it’s important to get your system checked our regularly because it would be to bad if it died on you when you need it. I’m also one for saving as much money as possible, so that’s another good reason.

    You make a good point about how condenser coils would become dirty very quickly when they are outside. My husband and I have an AC unit in our backyard, but we haven’t even thought about cleaning the coils! I think it might be time ofr us to call a professional to take a look at the unit. Hopefully it’s in good condition!

    Important of maintaining Air Conditioning should be kept in mind. Half yearly AC service should be done to make them better working for long life.

    As you said above, the coils can collect dirt naturally. The HVAC technician should make sure that during tune-ups or inspection the coils are serviced as well. This can double the effeciency of your unit.
