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.

I'm very happy I found HVAC Unlimited. I have an oil heating system and a number of companies I called won't service it. Despite having my furnace conk out overnight and calling Sunday morning, HVAC Unlimited sent a tech (thanks Jeremy!) by that afternoon. Before coming out he tried to talk me through potential problems on the phone to see both whether it was a fix he could walk me through, or whether it was a fix that he definitely couldn't make on a weekend, in order to save me time/money. After a few minutes he diagnosed the likely cause and headed out. The ETA was accurate, he showed up promptly and was friendly, professional, and courteous. He talked me through the issue, explained the potential problems, diagnosed the cause, and fixed the blown low-voltage fuse in less time than I believed possible, all while being considerate of my napping toddler. There's no doubt I'll call HVAC Unlimited next time I have an issue, and I'll hope Jeremy shows up. Thanks!
