Do These Four Things To Fight A/C Freeze
It’s Monday. Work was a bear, your boss was a jerk, and you missed a deadline you’d been working toward for a month. You got into your hot car and started the long commute home. When you hit your driveway, you wanted nothing more than to take off your too tight clothes and relax in your cool, comfortable home with an even cooler beverage. But your A/C had other plans. When you got home, the house was an oven.
A/C freeze up can happen on the hottest days. It’s a fairly common condition cause by a couple of potential problems that you can alleviate with some simple maintenance.
Common Causes of A/C Freeze Up
Probably the most common cause of air conditioning freeze up is that the airflow to the unit has gotten blocked. When the air gets blocked, that allows the condensation that naturally forms on the unit coil to freeze up. Unblocking the air can be as simple as changing your furnace filter.
The second most common cause of air conditioning freeze up is refrigerant leaks. This is potentially bad news for homeowners especially if your unit is older and still uses R22 refrigerant as this is very expensive. Topping of your coolant and may get your system back up and running, but it is likely a temporary fix. The key is to keep your system maintained all year long. Here are some easy tips to follow.
Easy Maintenance to Stop the A/C Freeze
Let’s tackle the A/C freeze up first. If you look at your unit, and it’s obviously frozen, here are some troubleshooting tips:
- ———-Check the furnace filter. If it is obviously dirty, change it. Make sure you set a note to yourself to change it more regularly in the future. Big box retailers like Home Depot sell furnace filters. It is usually best to purchase the more expensive filters unless you’re planning on changing it once a month.
- ———-Next, switch the thermostat to OFF and the fan to ON. This will begin to defrost the unit. It’s going to take a few hours for the unit to thaw out.
- ———-While you’re waiting, check your condensate pan to be sure it is draining properly. If everything looks solid, simply check on the unit periodically over the next few hours.
- ———-Finally, turn your a/c back over to COOL. If the air coming out feels cooler than your house, you’re back in business.
- ———-Start by putting your unit to a higher temperature and working your way down. Older units may not be able to cool as efficiently and you may need to run at a higher temperature to avoid additional freezes ups.
