AirMaster Heating & Cooling holds NH HVAC licence MBE2401615, active on the state registry. Its website lists heating installation and repair, furnaces, heat pumps, ductwork installation, boiler installation and repair, air conditioning repair and installation, and thermostat installation, and says it has been in business 7 years. On its Thumbtack profile it describes itself as a small, two-person team. A recent customer says AirMaster installed the entire system in less than 9 hours, from removal to up and running with the new system. Another recent customer says Val made suggestions on where to place the indoor and outdoor units of a mini split system bought for their basement, and walked them through the installation process. In a 2026 review, a customer whose tenant had no hot water found a third-floor water heater leaking; that customer said Val came the same day after sending an itemized breakdown. The same 2026 reviewer said Val steered them away from a more expensive water heater at their own request. A 2025 reviewer said two local companies quoted the exact same hardware and Air Master was almost $8k less. In a 2019 review, a Durham customer said Val and his helper laid a concrete pad, installed the outside condenser and connected two wall-mounted and one ceiling-mounted Mitsubishi mini-splits; that 2019 reviewer added that Val made sure they took advantage of a rebate on the mini-splits. A 2020 review says Val installed a new Bosch boiler and a heat pump water tank. In a 2018 review, a customer with no ductwork said Val gave several suggestions for installing A.C. in their multi level home and crawled through a crawl space in the attic to be sure he could place the master bedroom unit where they wanted it. The Better Business Bureau gives AirMaster a B- grade and shows 1 complaint on file.
Airmaster heating and cooling responded promptly, Quoted me a reasonable rate quote, followed through on every statement and request and installed the entire system in less than 9 hours from removal to up and running with the new system. The technician was very understanding and answered all my questions! I would gladly recommend this company to anyone that needs a heating and HW system replaced! Very professional!
Val responded to our request for installing a mini split system that we bought for our basement. He made great suggestions in where to place the indoor and outdoor units, and walked us through the installation process. The price estimate breakdown was nice and clear. It was a great solid work by Val, will definitely hire him again for any future HVAC jobs that we need!
Val is the man! I am so happy I got in contact with Airmaster Heating and Cooling. A few days ago I woke up to my tenant calling me to tell me that she had no hot water. I raced down to the basement to find, indeed, my third floor water heater was leaking profusely. Clearly, it was time for replacement. I had called around for plumbers and everyone was telling me they could only visit in the next couple days. Perusing on thumbtack, I found Val of Airmaster Heating and Cooling. He was recommended as "exceptional" and could not find a bad thing about him. Now I know why. He was the first to answer my call for help directly without going through a receptionist. He offered to come the same day after sending me an itemized breakdown (I am sure he cannot always come same day but on this occasion he could, I was lucky) and he brought everything he needed within hours. He steered me away from a more expensive water heater at my own request. I have worked years in sales so I know what a sign of integrity that is: to guide someone through a world they know little about. How people act in that asymmetry is a sign of character. He worked efficiently and pointed out some knowledge about what will happen next. This day of repair could have gone so much worse. Could have been dragged out, could have been upsold and charged more than necessary, could have had additional headaches. Thanks to Val and his company Airmaster, it was simple. Good to know another trustworthy person around here.
He responded to my query quick and very clear and professional on his communication and work quality. His pric8ng was very affordable. he came on time as committed and got the water replaced in my apartment. I had few question on next day when I saw water dripping because of condensation and he was very prompt to answer them. I'd recommend AirMaster and going repeat for my other plumbing need.
I highly recommend Val. He is a no nonesense, hard worker and someone you can definitely trust to show up on time and do the job as promised. I was quoted the exact same hardware from two local companies and Air Master was almost $8k less. HIGHLY RECOMMEND
