Air conditioners can have all sorts of issues. Some are easier than others to troubleshoot. If your air conditioner is having trouble blowing air, it could be frozen. If you’re not sure what that means, or if you do know what that means and don’t understand why it’s happening, check below for popular reasons why this could be happening to your air conditioner.
- Lack of Freon is one of the top reasons why your air conditioner could be freezing up. You have to be certified to add Freon to your air conditioner and it will take a special set of gauges to check the levels.
- An air flow problem could also be causing your air conditioner to freeze up. The first thing you’ll want to check is your filter. If your filter is clogged, it will cause your unit to freeze. Your filter should be changed a minimum of two times a year. You should be changing it more than that if possible.
- Check the evaporator coil also known as the A-coil to see if it’s dirty. The evaporator coil is shaped like an A and is actually located in your furnace. If it’s clogged or dirty, it will cause loss of air flow which will in turn cause your air conditioner to freeze up. The coil can be cleaned with a stiff scrub brush or wire brush. Brush across it lightly to remove the dirt and debris carefully. You can also purchase a coil cleaner from your local home improvement store.
- A dirty fan blade on the blower in your furnace can also cause lack of air flow which, as stated earlier, can in turn cause your air conditioner to freeze. Also, if your blower motor isn’t working at all, it will cause your air conditioner to freeze.
Note: If you are unsure of what could be wrong with your air conditioner, please ask a professional for safety reasons. You could also save yourself money in the long run by asking before trying to fix it yourself.
