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!
