How to check for freon leak in home AC?

The chemicals that cool the air within your air conditioner are called refrigerants or freons. The refrigerants R-22 and R-410A are commonly used. Even though these chemicals are enclosed inside the system, corrosion, physical harm, or poor installation can cause leaks. I can share a few ways that can help you with how to check for freon leak in home AC.

How to Check Freon Leak in Home AC?

Some of the common ways by which you can detect a freon leakage are:

1. Weak Airflow: As your air conditioner tries to efficiently cool the air, a decrease in airflow from the vents can be a sign of a refrigerant leak.

2. Warm Air: A leak in the refrigerant can be the reason that your air conditioner is unable to generate cold air.

3. Unusual Sounds: The presence of unusual sounds coming out from your air conditioner, including hissing or bubbling sounds, can be a sign of a refrigerant leak.

4. Ice Buildup: When the refrigerant flow is reduced, the evaporator coils freeze, causing excessive ice buildup on the coils or refrigerant lines to indicate a leak.

5. Increasing Energy Bills: An ineffective air conditioning system caused by a refrigerant leak can be indicated by an abrupt spike in energy bills without a matching rise in usage.

If you observe any of these issues, then there’s a chance that there is a freon leak from your AC unit, and it is crucial to get it resolved.
