A lot of air conditioners and heat pumps sold around the world use a refrigerant called Freon R-22. Emissions of R-22 are considered by some experts to be a significant factor in depleting the ozone layer that protects animals and people from harmful rays from the sun.

Consumers now have the choice to ask for an air conditioner or heat pump that uses a more efficient and environmentally friendlier refrigerant such as R-410A. As R-22 is replaced with safer refrigerants, the cost of maintaining equipment using R-22 may increase dramatically. That’s why Brennan offers R-410A so that you can avoid the rising costs associated with R-22. We’ll analyze your home comfort needs and recommend the system that makes sense for you.
