A freon leak can happen from a variety of different methods. I’ll cover the most common ones here.

  • My experience with Freon leaks has been entirely with refrigerants R-22 and R-12 used for household and automotive cooling. This article deals mostly with R-22, but touches briefly on the new refrigerants.

    How to Add Freon to the Air Conditioner. Air conditioners, in a perfect world, don't run out of freon. This substance is in a sealed area of the unit where it cannot evaporate, and it is constantly reused in the system. The reason that freon levels get low is because, over time, leaks develop. If you have a leak in a unit and repairs are not affordable at the moment, refilling the freon will normally get you through another season.

    Hold a thermometer up to the air vent to take a reading on the cool air. Take another temperature reading of the air being pulled into the unit and the air return. Do this while the unit is running. Take note of the temperatures and subtract one from the other to get the difference. If the number is lower than 15, then the unit needs to be charged with freon.

If you think your system is low on freon or is leaking, look at the repair history of the unit. Often times your air conditioner will have oil stains around the service ports outside if it is leaking freon. If the freon leak is in a tough spot, it can sometimes cost $1000’s to have the issue resolved. That being said, we guarantee to provide you with options for getting your system resolved for what works for your budget.
