Refrigerant Charge

To be properly calibrated, the refrigerant charge of your home’s air conditioning system must remain in a “goldilocks zone” – neither too low, nor too high, but just right. A low or high refrigerant charge reduces the capacity and efficiency of the system, leads to increased operating costs, and can cause compressor damage and shutdown. Our technicians assess the question of the system’s refrigerant charge by comparing temperature and pressure readings in a two-pronged approach: measuring the super-heat of the evaporator and the sub-cooling of the condenser.

Pledge: We will gauge the refrigerant charge using super-heat and sub-cooling measurements, and optimize the charge accordingly.
