New HVAC System Requirements and A2L Refrigerants

New Systems:

All new residential and light commercial air conditioners and heat pumps manufactured after January 1, 2025, must use A2L refrigerants. ( R-32 and R454B )

Existing Systems:

While current R-410A systems are not immediately required to be replaced, the availability of R-410A will decrease, leading to higher repair costs and potential difficulties finding compatible replacement parts.

Retrofitting:

Retrofitting an existing system to use new refrigerants is often not feasible due to compatibility issues and the costs involved.

A2L Refrigerants:

These new refrigerants are mildly flammable, requiring updated safety protocols and standards for installation and maintenance.

Price Increases:

The transition to new refrigerants has lead to increased prices for new systems, potentially impacting homeowners who need to replace their HVAC units. This is due to a RFID sensor that is required in all units with more than 3.9 lbs of A2L refrigerant.
