Why is Preferred Air different from other HVAC contractors?

Preferred Air Inc. has been servicing homes on Boston’s North Shore and surrounding areas since 1991. Through years of diligent effort and a focus on customer service, we have earned a community-wide reputation for honesty and professionalism.

Our company prides itself on using the latest in heating, cooling and comfort technology. There is more to your furnace, boiler, radiant, geothermal, ductless, heat pump or central air conditioning system than meets the eye. We will help you get the most from your existing system in comfort, safety, and energy savings. Our service technicians are factory-trained and on call 24-hours-each-day. Our service technicians all have neat appearances, are careful of their speech, and have respect for your property. They are all at the top of their field, and we are very proud to have them as part of our team.

Call us at 978-750-8282 or

While there are other well-established and conscientious HVAC companies on the North Shore, there are also companies with lesser credentials. We ask our homeowners to check the licenses and reputation of any contractor for which they do business. (Why is this important?). We are happy to provide references from other customers, or start by visiting our Testimonials page.

Preferred Air Inc. also offers a full-service sheet metal department, including a custom duct fabrication division. We specialize in custom ductwork for homes and businesses. Whenever the ductwork needs to fit and whatever size and shape it needs to be, our sheet metal team can do small change-outs to full-scale commercial jobs. We design/build everything we do and offer engineering services to meet unique needs.

Call today for your free professional system evaluation and estimate for upgrading or replacing your current heating and/or cooling system.

Celebrating Serving the North Shore Since 1991

These guys were awesome! I had Rob come out for my yearly maintenance on my furnace before the cold weather set in. He was professional and explained things well. He was on time too! They were about $100 less the other people I got quotes from and it included a new filter! So pleased.

Brian just left and he is a Godsend! He made several calls to clear the work with my working husband and myself, all of which he did with great patience and professionalism. He was easy to talk with and showed me respect... I would refer this company to my best friend and family anytime!

We have been using PREFERRED AIR for a number of years. I have nothing but praise for them. Our technician Louis is very professional, courteous and always takes the time to explain whats wrong in layman's terms. Thumbs up to a great company, who has top notch people working for them.
Margaret M, Beverly MA
Preferred Air has done countless jobs for me. Installations, maintenance, repairs, you name it. There is a reason you continue going back to a company time and time again, quality, service and knowledge, each and every time the folks at Preferred Air have exhibited all three.

I found a puddle of water around my HVAC and was very worried. I called them at 7am hoping to only leave a voice message. Louis answered the phone and he was professional and compassionate. I really appreciate his help. Preferred Air will be my go-to company for any future issues!
Danielli T, Frederick, MD
This is a great company that installed a new system in our home. They did a great job and I highly recommend them to anyone who needs a replacement system. They were quick, friendly and professional. The cost was reasonable and we were very happy with the end result.
Ronald C, Peabody MA
Luis was awesome!! He was extremely professional and it was obvious from the outset that he knew exactly what he was talking about. He checked everything thoroughly and advised me on the things that I could do on my own to fix any future issues. Highly recommend!! A++++++++
