“Really impressive. I was well informed, work was quick and very tidy. I guess what I liked most, was that I felt comfortable in my own home. I am usually tip toeing around when contractors are in my house.”
Rich Mathews & Son Inc.
A/C Repair & HVAC Contractors in Derry
Average rating: 5 out of 5 starsDecember 10, 2016
“I contracted Rich to replace a forced hot water boiler and electric hot water heater. He was an absolute pleasure to work with, focused on doing the right thing for a very reasonable price. I had tenants that had no heat and cold weather fast approaching. Rich was responsive, and took the time to make sure he was doing things right. While on the phone, Rich looked at the property on Google maps to understand how he was going to get the new boiler in, came over after hours to check over things and take measurements. I got multiple bids from other contractors, and Rich was the only one to provide open, honest recommendations that had my best interests in mind. He pulled permits, showed proof of insurance and was accommodating around my work schedule. Not only that, but his relationships with others in the industry proved immensely helpful, including a referral for a very competent electrician, and being on first name basis with the inspector. I have no doubt my job was done right. His knowledge and attention to detail are top notch and I would highly recommend him.”

Obie Comfort Solutions
A/C Repair & HVAC Contractors in Derry
Average rating: 5 out of 5 starsMay 12, 2016
“I had Obie come in for a weekend rush service and they were able to come by only a few hours later, and had the issue fixed relatively quickly. The fee was reasonable and they were more than happy to talk to me about heating systems, and even though we talked for at least 45 min, they didn't charge me for the info, and didn't even really try to sell me on the product; frankly, they told me that it probably wasn't worth it for me. I would absolutely use Obie again.”
ET Radiant, LLC
A/C Repair & HVAC Contractors in Derry
Average rating: 5 out of 5 starsJanuary 29, 2018
“Eamon is an excellent professional and a highly responsive and responsible person. He installed radiant heating in our basement six years ago. Since then he helped us with a number of smaller projects. Recently there was a plumbing problem with the heating circuit; Eamon responded immediately and fixed the problem the same day. I highly recommend his service.”
MacDougall Plumbing and Mechanical LLC
A/C Repair & HVAC Contractors in Derry
Average rating: 5 out of 5 starsJuly 11, 2014
“We had to call on an emergency basis and under very difficult conditions. We had just brought my Dad home with hospice, and were coping with the reality that we were in the final days. With my Dad only feet away the downstairs toilet began spewing water into the kitchen - and it wouldn't stop. Mr. McDougal arrived quickly and handled the situation - inevitably discovering that the problem was a pipe a distance from the house - and arranging for additional professional support to solve the problem. It took hours, it was late and we were already overwhelmed. He managed a difficult situation and solved our plumbing problem under difficult conditions and circumstances. We were very grateful.”

Average rating: 5 out of 5 starsNovember 6, 2014

What do HVAC contractors do? HVAC stands for heating, ventilation and air conditioning. An HVAC technician or contractor specializes in heating systems, air duct cleaning and repairs, insulation and air conditioning for your Derry, NH home and other homes.

When should you hire local HVAC companies?


Generally, Derry HVAC contractors or HVAC installers work with or run companies that repair or install heating systems and a/c services for homes.

Local air conditioning companies can help with a wide variety of air conditioning services, including both a/c installation and a/c repair. Air conditioning contractors, also known as a/c contractors, get extremely busy in the summer when temperatures are highest. For larger jobs, like installation, you might want to hire a/c installers during the off season like spring or fall. You should also try to do the same for heating services. Heating installers and heating contractors might be more available in the summer or fall for larger projects.

Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)

Find HVAC contractors, heating companies and air conditioning installers on Houzz. Look in the Professionals section of our website and search for New Hampshire HVAC contractors. Read reviews and see how an HVAC contractor might approach your Derry, NH home’s heating and cooling challenges.
