We bought from and had Al's install a new 50 gallon Rheem gas water heater. We were very pleased with the professionalism and competence of Brian McCarthy. The service crew was also excellent throughout our experience. We recommend Al's Cooling and Heating without reservation.

Best value and excellent installation. Very responsive to customer needs. Included items like a condensate neutralizer that otherâ s who quoted did not. I highly recommend.

An absolute pleasure to deal with from start to finish. A++ service and a company that cares for their customers. A company that doesn’t try to upsell you, but rather focuses on fixing the immediate problem economically. Integrity! A rarity nowadays. We are now a customer for life for all our furnace and air conditioning concerns.

Had an issue with my heating system Saturday morning (10/7), Brian talked me through what potentially could be wrong. He suggested he comes to take a look Monday morning(10/9), he came out, fixed what needed to be fixed and for a reasonable price. Will use AL's Cooling & Heating for all of my future HVAC needs

The crew was quick and courteous. I had three estimates, and Alâ s was the best value by far.

Brian & Geno did excellent work auditing my install of the furnace and AC before completing the lineset connections and system charging for both of my AC systems. They located a lineset breach (a failed solder joint) deep in a wall and repaired with a new braised joint. Everything is working great and, although the final cost was considerably higher than the quote, was still very reasonable for the additional work performed. I couldn't ve more pleased. Al's will be my go-to team from now on and will direct my contractors to use them as well.

These guys get it done. We initially called a couple different vendors to address a tenant cooling issue in the middle of a state wide heat wave. The second vendor we called to the location on two different days produced no results. These guys got it done before noon on the first try! Make them your first and last call.
