How much does it cost to add Freon to a heat pump?

The cost to add refrigerant to a residential heat pump typically ranges from two hundred to six hundred dollars or more, depending heavily on the type of refrigerant your system uses, how many pounds are required, and labor rates charged by your local HVAC company. Older systems using R-22 Freon are significantly more expensive to service due to supply phase-outs, whereas modern R-410A refrigerant is more affordable. It is crucial to remember that refrigerant does not get consumed during normal operation; therefore, adding Freon without first locating and repairing the underlying leak is a temporary fix that will quickly leak out again. You can verify the value of the service by ensuring the technician performs a thorough leak search and pressure test before recharging the system to manufacturer specifications.
