Why Is My Air Conditioner Frozen?

If you turn on your air conditioner only to find that it is blowing warm air, your first reaction will be to look around for the potential problem. Sometimes, as you search for the problem, you’ll find that there is, quite literally, ice on your unit. If this is the case, don’t fear! This does not mean your system is ruined. Often, a frozen air conditioner has a simple fix. Here’s what you need to know about this common problem and how to solve it.

Causes of a Frozen Air Conditioner

The most common reason an air conditioning unit will freeze is because of a problem with the unit’s refrigerant. This collects the heat from your home and moves it outside. Over time, leaks can develop, causing the system to lose refrigerant. Without enough refrigerant, the coils become too cold, creating the ice buildup you can see. Add a humid Rockford day or dirty coils, and you have an even greater chance of having this problem.

The second cause for a frozen air conditioner is improper airflow. If the air filter is dirty or you have some other obstruction preventing proper air flow, then the air conditioner cannot function properly. Without proper air flow, the temperate in the coils will drop below freezing, and any humidity in the air will collect on them and freeze.

How to Fix a Frozen Air Conditioner

If your air conditioner is frozen, the first step is to check your air filter. If it is dirty or if you are using the wrong type for your system, then change the filter. This may fix the problem.

Of course, if that doesn’t solve the issue, give the team at Axberg a call. We have the tools to check your refrigerant levels and inspect your system for other blockages.

Axberg Reviews
I woke up this morning to a very cold house. Unfortunately I don't already have a "Furnace Guy" that I usually call. So I made 2 calls to local HVAC companies before calling Axberg. The first one said some thing like "We can get someone today, but it will be after 4 pm which is overtime, so there will be an extra charge" The negative response to my call made me feel like I was troubling them, and that I would be silly to pay the extra fee to have them come out, so I declined. My next call was answered by a machine, so I hung up. I couldn't take a chance on wasting time waiting for a callback. My call to Axberg was answered by a very helpful voice. She indicated that she would get someone to me as soon as possible, but they were very busy with the cold weather, so it might be between 5 -7 pm. I agreed but about an hour later I was surprised to received a call letting me know Ryan would be knocking on my door within 45 minutes or so. I found Ryan to be very friendly, knowledgeable, and professional. He was able to quickly diagnose the problem and I had heat again within the hour. I could not have asked for a better experience. The price of the repair was very reasonable. During the repair process, Ryan was able to answer all of my "layperson" questions concerning my furnace and gave me some ideas of how to get the most from my furnace to heat and cool my home. I was impressed by the fact he put the shoe coverings on upon entering the house, his tools were all kept clean and orderly and he seemed to have all the special tools he needed to maintain my furnace. I am very happy to have chosen Axberg to service my furnace today!!
