Keeping your air conditioner clean is important in the summer. Dirt, in the form of grass clippings, pet hair or mud will block the air flow. When this happens, you will notice a decrease in performance. Condenser coils need to be cleaned because they are exposed to the out door elements. You can maintain condenser coil efficiency by simply washing the unit. Turn off any electrical power first to your system. The evaporator coils are harder to get at. The visual check is not as simple as the condenser coils. But they are in need of maintenance as well. Since the evaporator coil is continuously exposed to airflow circulated by the blower, it’s susceptible to buildup of dust or dirt. When airborne particles form a layer on coil surfaces, efficiency of the heat transfer from the air to the refrigerant is diminished.
If your system seems to never shut off, there may be an issue with your thermostat. It may be that your home has reached the correct temperature, but the thermostat is not registering the conditions in the home. In this case, your air conditioner unit will continue running. One way to check the thermostat is to place another thermometer near the location of the thermostat. After an hour or two, check the reading. If it is at or near your desired home temperature, there may be a problem with your thermostat. Make sure to contact us so we can inspect the thermostat for you.
Poor sealing or insufficient insulation is another common culprit, which can cause your unit to run constantly and inefficiently. If your home is not closed up tight while your air conditioning system is in use, you may be losing cool air that you need during the summer through small holes or non-insulated walls or roof. If there are air leaks in your basement, the air is forced out. This can negatively impact your summer cooling bills.
