When the weather is hot the last thing you want is a malfunctioning air conditioner. To avoid this, it is recommended to get your air conditioning checked by a professional technician. When your unit runs efficiently, it will use less electricity. When the filter and coils are clean, the unit doesn’t have to work as hard to produce the same amount of cool air.
Keeping the filter clean is the most important task a homeowner can do to help keep the unit running efficiently. When the filter is dirty, it obstructs the air flow, and the air that does make it in usually brings dirt to the evaporator coil, impairing the coil’s ability to absorb heat. According to the U.S. Department of Energy, a clean A/C filter will reduce your energy consumption by five to 15 percent.
A clean filter will slow the process, but the evaporator coil and condenser coil will eventually become dirty. The evaporator coil should be cleaned at least once a year. The condenser coil may be outside. It can be kept cleaner longer if there is no foliage nearby or other debris such as lawn clippings.
Evaporator drains carry out the excess moisture from your indoor air. If the drain is blocked with mold or mildew, you may find water spots on your walls, floor or ceiling. You can occasionally pass a wire through the drain’s channels to make sure it isn’t clogged.
Optimum air flow throughout your home or office is also important for reducing energy consumption. If an area of the house doesn’t receive cool air, it will raise the overall temperature of the space. This causes the thermostat to read the room as hot, which in turn causes the unit to unnecessarily overwork.
