Freezing AC units during the summer is an all-too-common problem for homeowners today. Let’s look at why this issue occurs and what you can do to prevent this from happening.
Why Does My AC Freeze Up In The Summer?
Hot weather puts stress on your AC system. If the evaporator coils become too cold, the system can start to freeze under a few conditions. Let’s look at a few issues and how you can avoid your AC freezing up during the warmer months.
Low Refrigerant Levels
Low refrigerant levels may be to blame when a unit freezes up in the summer. An AC unit requires a certain amount of refrigerant in order to maintain optimal performance. When levels fall below the recommended amount, it can result in the AC freezing.
Frozen coils can be a sign of low refrigerant levels. This issue needs to be addressed as soon as it is noticed. It’s strongly recommended to contact the HVAC professionals at this time.
Blocked Vents Or Dirty Air Filters
AC systems can freeze because of a buildup of dirt or blocked air filters and vents. Ultimately, blocked vents or dirty air filters are the common reasons why freezing occurs.
Air filters can collect dust from the environment in a few different ways. If your line vents are not cleaned or vacuumed regularly, freezing can result. Homeowners can take preventative steps like cleaning vents and changing filters regularly.
Damaged Wiring
It’s crucial to check all wiring from the thermostat, furnace, and outside condenser unit to prevent any freezing. If any electrical wiring appears to be burnt or torn, it should be inspected by the professionals.
Performing regular maintenance needs for your AC unit each and every year can save homeowners lots of headaches and money.
Condensate Drain Line Blockage
Condensate drain lines are necessary within an AC unit. The lines are responsible for removing any water that is generated by the cooling system. They will ultimately prevent it from back flowing into the unit or escaping into the home.
If the line gets blocked with a buildup of dirt or mold, it can lead to a backup of excess moisture. This can lead to damage of the system and/or your home. Get your drain line inspected by a professional HVAC company to prevent any issues.
