Air Conditioning Repair Tip: Causes of Frozen Coils

Tuesday, June 4th, 2013 at 10:06 am

You depend upon the integrity and solid working condition of your AC to ensure that you stay cool and comfortable no matter what the outside temperature is, but a frozen evaporator coil tells you that your cooling is not nearly as effective or efficient as it could be. Make sure to get this checked out immediately by a qualified professional. Call Next Generation for comprehensive air conditioning repair in Melbourne, FL.

Here are some common causes of frozen coils that you may encounter this summer.

  • Clogged air filter: Your air filter prevents the accumulation of dust and debris on sensitive mechanical components. It should be checked about once a month during the cooling season, depending on where you live and the surrounding air quality, as well as the condition of your ductwork. But if it goes neglected, it’s subject to clogging. This significantly limits the amount of air that can pass through your system, and can block cool air inside the evaporator coil, leading to frozen coils.
  • Low refrigerant: When it was professionally installed, your AC was given a certain amount of refrigerant “charge,” and this level should always remain the same. But over time, your AC may encounter physical damage or corrosion that can lead to a puncture in the coils. When this occurs, refrigerant may leak out of the circuit of coils and devices, and even minor leaks can lead to inadequate cooling and energy inefficiency. This also can disrupt the ability of your evaporator to operate, which can lead to it freezing over.
  • Blower motor malfunction: Your blower motor extracts warm indoor from your home and sends it through the evaporator where it is cooled with the cool liquid refrigerant. But if the blower motor is not working properly, then this entire process is disrupted, which can lead to frozen coils.

Make sure that all aspects of your AC are working well before summer arrives. Call Next Generation today for exceptional air conditioning repair in Melbourne, FL.
