You’re in your home on a hot day with the air conditioning on full blast, but you notice that it can’t possibly be working efficiently because you’re still sweating. You go to have a look at your unit and you see ice. What’s the deal here? Why is your air conditioner frozen while you’re inside sweating?
There could be a number of different causes for this, but there are things that you can do to diagnose your frozen air conditioner and get your home back to your desired temperature:
Luckily, a frozen air conditioner isn’t a difficult thing to spot. First, you’ll probably notice that it’s warmer in the house than you’d like so you turn down the thermostat. You wait a while, but discover that your home still isn’t cooling down.
You decide to take a look at your air conditioner to see if something is wrong and find a buildup of ice. That’s all there is to it in most cases.
Another way to find this problem is by placing your hands over the air registers to see if the air is coming out cool as it’s supposed to. If not, you’ll want to take a closer look at your unit. If you can’t easily see the ice, you should use your system diagram to find out how to unscrew the panel to the evaporator and see if ice is present.
You could potentially find ice on the panel, ice on the coils inside, or you may notice the refrigerant is reading below 32 degrees.
Now that you’ve determined you have a frozen air conditioner what should you do?
In many cases, fixing a frozen air conditioner is something that a professional HVAC technician will need to do. However, there are some things you can try first, if you want to:
If you’ve tried the above steps and find out that your air conditioner is still frozen, you’ll want to contact a professional air conditioning repair service and have them come out and inspect and repair you’re A/C system.
Having a frozen air conditioner is not something you’ll want to try to let go and ignore, hoping it will get better. Troubleshoot if you can, but don’t be afraid to call for help.
