With summer in full swing and plenty of hot weather in the forecast, it’s essential to ensure that your air conditioner is operating as effectively and efficiently as possible. Unfortunately, AC units don’t always operate the way they’re supposed to after initial air conditioning installation in Oregon City, OR, for a variety of reasons. One of the most common issues home and business owners experience with their AC is freezing. Read on to find out more about why freeze-ups occur, what you can do to prevent this from happening and how you can address this problem when you encounter it.

Why freezing occurs

Residential and commercial air conditioning units require proper airflow to operate effectively. When air is obstructed or isn’t flowing freely through your air conditioning unit, the condenser coil might accumulate excess moisture and freeze up. A little bit of frost likely won’t cause major complications for your unit, but this frost can spread and lead to problems with the efficiency and performance of your air conditioner.

One of the most common causes of a freeze-up is a dirty air filter. If you don’t change your air filter regularly, airflow into and out of your unit will be restricted. Another common cause of freeze-ups is low refrigerant and malfunctioning fans.

Preventing and addressing freezing

No matter what kind of air conditioning unit you have, it’s essential to take the proper maintenance and care steps. There are several things that you can do to prevent freezing from occurring and to get your AC unit back to normal after it freezes:

  • Change your air filter: You should change your air filter regularly to ensure that air can flow properly through your unit. Filters need to be replaced every one to six months, depending on the type of filter and a variety of circumstances in your home, including the size of the house, the presence of pets, the age of the HVAC system and more.
  • Check refrigerant: Check your AC unit’s refrigerant levels and refill the refrigerant as necessary to promote proper cooling.
  • Unfreeze the coils: Once you’ve found the source of the airflow problem and fixed the issue, you will need to unfreeze the coils. You can do this with a hair dryer on a low setting or contact a professional technician for help.
  • Invest in regular maintenance: The best way to prevent freezing and to improve the overall longevity, efficiency and performance of your AC unit is to have regular maintenance performed by a professional.
  • Consider replacement: If you are dealing with consistent, ongoing problems with your AC unit, including frequent freezing, it might be time to consider replacement. Contact a professional who specializes in air conditioning installation in Oregon City, OR to find out whether this is the right option for your home or business.
