Why Is Your AC Freezing Up?

AC Freezing UpAir conditioning is a must during the summer months, and when it malfunctions it can feel as though it’s the end of the world. With your AC freezing up, you want to get it back in working order as quickly as possible. In order for that to happen, you need to know why it’s freezing up in the first place. Brown Service Co. is here to offer an explanation as to why your AC might be on the fritz.

Improper Air Flow

Air conditioners need the right air flow in order to keep the cold coil heated. Without warm air from your home, the coils freeze up before the condensed water has a chance to properly drain away. Closed air registers and dirty air filters can block the flow of air, which is why you want to make sure that your registers are open and clean.

Your Fort Worth HVAC system may freeze up whenever the fan isn’t working as it should or when there isn’t enough refrigerant. Improper refrigerant levels freeze up the coils, and a bad fan can keep the air from moving as it should.

Blame It on the Thermostat

Your AC freezing up could also be caused by bad thermostats or drainage problems. As it cools, AC units condense the vapor from water into a liquid that drains away outside. Whenever the coils freeze up, a buildup of ice can keep the drain hole from draining as it should. Your unit will still work, but your home won’t be cooled correctly and your AC will also use more power than it absolutely has to. You can use a hair dryer to take care of the ice if you have a window unit, and you might also want to check for blockages in the drainpipe.

Now that you know the reason behind your AC freezing up, you’re ready to get it taken care of. Contact the experts of Brown Service Co. at 817-284-9204 for superior HVAC service at a fair price.
