Is Your Air Conditioner Freezing Up? Consider These Possible Causes

Summer heat waves make your air conditioner a necessity rather than a luxury. When the air conditioner freezing up keeps your house from cooling down, the entire family suffers. Here are a couple possible causes that may be making your A/C malfunction.

  • Obstructed airflow: One of the most common causes for your air conditioner freezing up is a clogged air filter. When there’s not enough airflow to warm the A/C coil and keep it from freezing, the condensed water will freeze before it can drain away. Make sure you check your air filter once a month and replace it as soon as you see the first signs of dirt. Another area to check: the vents in your home. Even if you do not use certain rooms, it is best to make sure all vents are open and air flows freely to ensure your air conditioner doesn’t freeze up.
  • Low or leaky refrigerant: Another common reason for your air conditioner freezing up is a refrigerant leak or low refrigerant levels. This issue will require a call to an experienced service technician who can inspect your A/C unit and determine the precise problem. Once the leak’s been sealed, the technician will charge the unit with refrigerant and your home will begin cooling down quickly. Always make sure the water is dripping outside the unit especially on hot days.  As soon as you notice a problem, call for service before you damage the expensive condenser unit.

When the comfort of your family is on the line, it pays to contact professionals who will make sure your air conditioning unit is working when you need it the most.

Heater went out Friday, late afternoon. I placed an email with the company and called back Saturday morning to confirm the company had received email. I was able to get Jeremy to fix the problem before I had to leave the house for a previously scheduled engagement. Jeremy was very professional and explained the service he was working on.
