Keep Your Air Conditioner From Freezing Up

Figuring out what is causing your air conditioner to ice up can be frustrating, but it is not an uncommon problem. There are a number of reasons for an air conditioner to freeze up, and it really doesn’t matter whether it is a window AC unit or a central air conditioner – the causes of, and solutions to, an air conditioner that keeps freezing up are exactly the same.

It is important to address this issue – a frozen air conditioner will not only cool improperly, but can actually be severely damaged if it keeps freezing up. If you have this problem, you have to address it immediately – it won’t solve itself. Here are some common causes:

1. Insufficient air flow across your air conditioner’s evaporator coil can cause it to freeze up.

2. If your air conditioner is low on refrigerant, then your air conditioner can freeze up. 

3. Air conditioners are designed to function in a very specific temperature range.

4. Mechanical failures can cause your air conditioner to freeze up.

In order to troubleshoot a frozen air conditioner, I’d recommend you do the following steps:

1. Check your air conditioner’s air filter, if your AC is freezing up. If your air conditioning filter gets clogged, then the restricted air flow can cause your system’s temperature to drop below optimal levels, causing your air conditioner to freeze up.

2. Check your evaporator coil if your air conditioner is freezing up. A dirty evaporator coil (the inside one) can cause a lack of airflow across it, dropping the temperature and causing your air conditioner to freeze up.

3. Check for restriction in air flow from your ductwork. Start by opening all air conditioning registers (the vents in your ceiling). Any restriction in air flow can cause your air conditioner to freeze over, so make sure that you also inspect your ductwork for leaks, bends or disconnected portions.

4. Check for extremely dirty ductwork if your air conditioner is freezing up (as in so dirty that it blocks air flow – a little dust is okay).

If you’ve performed the steps above to no avail, then it may, unfortunately, be time to think about getting a new air conditioner.
