Why Is My Air Conditioner Frozen?

While your air conditioner probably has the capability to make your home feel like the inside of an ice box, the AC unit itself should never actually freeze. However, it’s not uncommon for it to happen occasionally throughout the life of your air conditioner. A frozen air conditioner requires immediate attention from an HVAC professional, but homeowner should also have at least a knowledge of why and how air conditioners freeze, as it may help them prevent the problem from occurring again. 

Air conditioners can freeze for a variety of reasons, but it most commonly occurs when there is a blockage within the system that prevents air from properly flowing through the various AC components, as well as when Freon levels are too low. 

Obstructions

When an obstruction in the system prevents air from properly flowing through the components, the evaporator coils collect moisture from the air, which causes droplets of water to settle and freeze to the coils. The more humid it is outside, the faster the ice will accumulate, which is why homeowners often notice this problem on particularly hot and humid days. 

Low Freon 

Your air conditioner requires a certain amount of Freon for the system to function properly, so when it begins to leak out (which is a common problem), the unit will lose efficiency. When this happens, the air in the system cannot get pushed through with the required amount of force, which gives moisture from the air enough time to settle on the coils and freeze.
