Detecting and Fixing an Air Conditioning Coolant Leak

When your air conditioning system is no longer cooling properly, it may have an air conditioning coolant leak. Air conditioners built since 2010 use a coolant called R-410a, and older units used Freon. The U.S. EPA phased out the use of Freon because of environmental dangers when the substance leaks into the atmosphere. If your air conditioner is not sufficiently cooling your home, a service technician can find the leak, determine which coolant your system uses, and properly address the problem.

Detecting and Repairing an Air Conditioning Coolant Leak

Finding and fixing an air conditioning coolant leak requires a certified technician with the right equipment.Finding Leaks

To find an air conditioning coolant leak, the air conditioner technician uses a pressure gauge. This gauge measures how much coolant is present and determines the pressure level of the air conditioner. If the charge of coolant is too low, your air conditioner cannot effectively cool your home.

Determining the Type of Coolant

It is important to know whether your air conditioner uses Freon or R-410a. This is because a system that uses Freon cannot be refilled with R-410a. Different equipment is also needed for different lubricants in the repair process. Most air conditioners have a label on them that indicates what type of coolant the system uses. If it does not, the technician can check the A/C model’s age, and manufacturer or serial number to determine the coolant it uses.

Fixing Air Conditioning Coolant Leaks

HVAC technicians will find the source of the leak, such as a cracked gasket, that causes a small leak over time. The hoses that transfer the coolant may also have deteriorated and need to be replaced. If your air conditioner has other problems, such as an aged motor or malfunctioning circuit board, and the unit is more than 10 years old, the technician may suggest replacing the system with newer equipment that uses R-410a.
