Most homeowners are baffled when they encounter a frozen air conditioner in the middle of summer. While it seems to go against common sense, air conditioning repair specialists field dozens of these HVAC repair calls during the summer months. How is this possible, and why does a heating and air unit freeze when it’s warm outside? Hunter Heating and Air Conditioning has been providing residential HVAC services for North Carolina residents in the Guildford area for years and understands the causes. If you’re looking to prevent frozen pipes, then read on to learn the top three reasons a system freezes and the preventative steps you can take.

Air Conditioning Repair Technicians Spotlight the Top Reasons Your AC Unit Freezes 

Condensation Prevents the Evaporator Coil From Doing Its Job

As the warm sun beats down on your home, your HVAC unit kicks into high gear to counteract the heat. This causes condensation to form on the system’s evaporator coil. If too much condensation accumulates on the coil, then it can’t keep the water at a warm enough temperature. Once this happens, a small portion of the water will freeze. This, in turn, will create a blockage that causes further freezing.

The System Is Running Low on Coolant

The other most common reason for frozen units is a lack of Freon in the system. Without this chemical, your HVAC system simply will not cool your home. Freon is the most commonly used coolant in home HVAC systems, and air conditioning repair specialists warn that a shortage of coolant could be an indication of a leak that can cause blockages and increase the likelihood of frozen water. If you suspect this is the case, a repair specialist should be called in immediately.
