Why Does My Ac Condenser Freeze Up

Why Does My Ac Condenser Freeze Up. When evaporator coils on an air conditioning unit becomes too cold, the ac unit pipes freeze. If the evaporator coils develop a small pinhole leak, the refrigerant will leak out.

When nights in the summer time are colder than the optimum threshold can account for, it can throw an ac out of whack. Several culprits can lead to inefficient operation and the ac unit freezing up. Running the ac with frozen coils strains the ac compressor.

The Refrigerant Gas Is Supposed To Stay Inside The Coils.


When your ac system is freezing up it is generally going to be caused by one of two things. The air, which is now cool, is blown back into the home to areas that your thermostat, i.e. If the refrigerant levels is low because of a leak, this can seriously mess with the unit.

The Ac Compressor Is The Most Expensive.


1) lack of air flow means the system is freezing up because it is not receiving the required amount of air (or heat in that air, rather) it needs to keep it from freezing up. Running the ac with frozen coils strains the ac compressor. Make every effort to avoid using the ac while the evaporator coils are frozen.

Poor Airflow Over The Evaporator Coil.


If the obstruction is near the evaporator coil, the most likely issue with your system’s. A properly functioning ac system extracts the warm air from inside your home and. This can lead to increased moisture in the system, which could cause the evaporator coil to freeze up.

Unusual Amount Of Condensate Drainage.


This fan blows air through the coils and can freeze up, causing your blower to make a rattling noise. This stops air from flowing properly and freely around the unit causing it to back up and freeze as it cannot cross the evaporator coil and back into the unit correctly. The heat is absorbed into the cold refrigerant, turning it from liquid to gas.

However, If The Drain Pipe Is Clogged Or Otherwise Hindered, Too Much Condensation May Develop On The Coils.


When a filter, vent or ductwork is clogged it can. From my experience the more occupants that are in a home the faster that air filters get dirty. Air conditioners are calibrated to operate within a certain set of optimum temperature thresholds.
