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.

Brian and his team got our hot water back up and running as soon as they could. And they're one of the only contractors around who seem to know about heat pump waterheaters. They were professionals and would definitely call them again if needed.

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.

Brian and the team did a great of getting an estimate to me in a timely manner and coming out the very next day to make the repairs. The guys did quality work and made sure all concerns were addressed. Great experience with them, highly recommend and will be using again in the future.

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.

After 40 years (maybe more) I found myself in need of a new furnace. I had contacted Al's Cooling and Heating earlier in the year when it first started acting up. They repaired as well as they could considering it's age but I knew the end was near. So a couple of weeks ago I knew it probably wouldn't make another winter so I called Al's. Brian came out the next day to give me a quote which I thought was fair and now I have a shiny new furnace. It turned out to be a bigger job than I thought, (LOTS of rusty duct work) but the price stayed the same. I particularly appreciated the fact that unlike some contractors, Brian never "talked down" to me because I'm a woman and when they were done he helped me with the financing to make sure I got a good rate and a reasonable monthly payment. I cannot say enough good things about the whole experience and about Al's Heating and Cooling. I have already recommended them to a couple of people. When my AC finally bites the dust (it's almost as old as the old furnace), I will be calling A's Heating and Cooling, knowing that I'll have another worry free experience. Thanks Brian.

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

They did an excellent job at an amazing price! The owner even followed up to make sure I was satisfied with their work and to see if I had any questions! Thanks for everything! I'll be referring you to anyone I know who needs HVAC work!

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.

Brian McCarthy was fantastic. Came out on same day as call, 30 minutes later our compressor was fixed. He did not try to sell us a new unit, he will be getting all of our heating and cooling work! Laura Murphy
