3 Reasons Your Home’s Air Conditioning Unit Keeps Freezing Up

Air Conditioning

In the warmer months, you probably rely on your home’s HVAC system to keep your living quarters cool and comfortable. While a problem with your air conditioner may not pose a life-threatening problem, you still want to avoid any downtime. Getting a seasonal checkup of your system by an experienced HVAC company in Kilmarnock can help you extend the life of your air conditioner. In addition, knowing what might cause your AC unit to freeze over can help you avoid that frustrating situation.

Low Refrigerant
The refrigerant is a cooling chemical that’s used to treat the air as it passes through the evaporator. However, an insufficient supply of refrigerant will prevent the air from being properly cooled. As a result, the moisture in the air will coat the evaporator, where it will begin to freeze. If you don’t catch the problem, the untreated air will continue to freeze and form ice crystals over the evaporator coils.

Dirty Air Filters
If the air filter in your AC unit is dirty, it will slow the flow of air through the system. The air that does go through the system will freeze as it passes over the evaporator instead of just getting cooled. You can easily correct this problem by cleaning or replacing the air filter.

Damaged Blower Fan
If your blower fan isn’t working properly, it won’t be drawing in enough warm air to keep the flow of cool air moving through the system. As a result, the air will freeze as it passes over the evaporator. You’ll have to have an HVAC company in Kilmarnock replace the blower fan to correct the issue.
