Is your central air conditioner forming ice? Are you concerned about freezing in the interior unit or the outdoor lineset? Do you want to know why before you call an Orlando area AC company? It helps to do a check yourself, so you know what kind of air conditioning repair service is in order. Before you do, let’s go over what you might find, and what, if anything, you can do about it.
Here are some common things that can cause ice to form inside your air conditioner.
First: you’re experiencing refrigerant issues. Low refrigerant or an incorrect charge can cause problems with your AC. This is because refrigerant is the part of your air conditioner that actually … you know … conditions the air. It collects the heat in your home and gets rid of it. Over time, leaks in your system, poor maintenance, and just old-fashioned wear can drop your refrigerant levels below the optimum, which can cause your air conditioner to form ice. It develops on the evaporator coils. If they are dirty or it is particularly humid, the problem can worsen quickly.
What do you do? If you live in Orlando, call an air conditioning repair service and have them inspect your refrigerant levels. They’ll check for leaks, charge your system properly, and get it all going again.
Second: improper airflow. If air isn’t flowing through your system properly, you’ll see ice forming on the coils before long. It’s a bit like suffocating your system – it’s choking on too much air, which causes the air to drop below freezing, which in turn causes the condensate on the coils to freeze over. It gets worse the longer it is left unchecked. The root cause of this kind of freeze is usually a dirty air filter. Those are supposed to be changed every month or two – check out your specific manufacturer’s guidelines for that.
The obvious solution is to change the air filter, of course, but if you’ve gone too long without doing that, it could have dirtied or damaged other parts of your system, in
There are a few other things that can cause ice to form in your unit, most of which are related to the two we’ve already gone over. You might not have enough return ducts, or your ductwork could be too small, too large, or damaged. Your evaporator coils could have gotten dirty. No matter what the root cause, it’s important to attend to it as quickly as possible. Do what you can on your own, but have your Orlando AC company phone number handy, just in case.
