Roughly 84% of American homes have some kind of air conditioning unit.
With so many people using air conditioners it is surprising how few people actually know how to maintain them. Many common problems stem from a lack of AC maintenance, including HVAC systems freezing up during the summer.
But if you don’t know how to take care of your air conditioner, that’s ok, there’s always time to learn! In this post, we’ll go over some of the most important AC maintenance tips that will help you keep your ac system from freezing up this summer.

Check Your Air Filter
The most common reason that an AC system will freeze up in the summer is airflow issues caused by a clogged air filter.
Clogged air filters are less effective and aren’t able to catch all of the particles and dirt that they’re meant to. Eventually, these particles will begin to build up on the coils of your HVAC unit, making it so they can’t work properly. Not to mention lowering the air quality in your home.
Then can then cause the temperature of the unit and coils to get too low, causing it to freeze up.
To avoid this happening, be sure to check your air filter regularly. Depending on the season and weather they may get clogged faster than expected, so checking them regularly is critical. When you notice it is clogged be sure to change it as soon as possible.
Check Your Condensate Drain Line
Your air conditioner dehumidifies the air and catches the resulting condensed water. It then keeps some of the water to help with cooling your home and pushes the rest out of the house through the condensate drain line at the back of the unit.
If any of this system gets clogged, then the tray that catches the water can end up overflowing. This excess moisture hits the evaporator coil and makes it more likely to freeze.
Check for blockages in this system, or have a professional HVAC technician come out to do it for you. If any are found, try and suction them out with a wet/dry shop vacuum.
To avoid the system freezing up you also need to be sure that it is positioned in a way that will allow the water to drain. If it’s not already in a good position, try and tip it so that the water can flow freely out the back and out of the house.
Make Sure Your Vents Aren’t Blocked
Closed or blocked vents can also contribute to airflow issues that end with your air conditioning unit freezing up. While you may think you’re saving money or energy by keeping some vents closed and only cooling some parts of the house, it can do more harm than good.
Make sure that all of your vents are open and that there isn’t any furniture or decor blocking them and their airflow.
AC Maintenance to Avoid Freezing Up This Summer
There is nothing better than having an air-conditioned home to go into after a long, hot summer day. But without the proper ac maintenance, you could wind up having a host of problems with your HVAC system.
