Customer Reviews


My entire unit went out unexpectedly and I received several quotes that were outrageous. McMasters came over and gave me a reasonable price. I was highly impressed with the professionalism of all people. The installation guys were great and the whole process was easy. Great company that is honest and trustworthy.

I would like to thank you, and the entire McMaster Air & Heat Company in their professional manner, and installation of our Furnace\AC Unit. Although we haven't use the AC Unit yet, the Furnace heats the house so fast that we've only need to run it for about 5 minutes, and we're good. . .

I recently had McMaster Heating and Air installed the Carrier Infinity HVAC system in my house. I did my research and compare the cost and product specifications with different Carrier Authorized Dealers. I chose McMaster not only for great cost savings, but also for the reputations since they also installed . . .

What a great company! Thorough, attentive, polite, and knowledgeable. They installed a complete new HVAC system, including new duct work, in my 66 year old home. Everything is great! Had an issue during our recent 10-day extreme heat event and they came to service the A/C unit in less than 4 hours. . .

Custom-Designed Residential Heating System Solutions

We pride ourselves on our ability to custom design home heating systems that are correctly sized for maximum efficiency, cost savings, and superior indoor comfort. Our whole-home approach to heating system design is based on a thorough evaluation of our client's current HVAC system performance, indoor comfort preferences, and budget. Before designing a new or replacement heating system for your home, we evaluate a number of factors such as energy efficiency ratings, humidity levels, temperature control, noise reduction, and utility costs. When necessary, we can also complete benchmarking load calculations and leakage testing for clients who desire to downsize to a more cost-effective heating system. Every system we sell also comes with an official AHRI Efficiency Certificate that details the exact efficiency rating for your specific combination of HVAC equipment.
