DiPietro Heating • Cooling • Plumbing
Londonderry, NH Air Conditioning and Heating Companies
Oct 10, 2016
“We had been running our units constantly really really cold and they are old (about 8-10 years). When DiPietro Heating, Cooling, Plumbing & Electrical first came out they initially thought we might need new units, but one of the guys came back a few days later after the unit was thawed out and educated us on how we should be using them and they were fine. They were so honest, they could have easily replaced them and we wouldn't have known. They saved us so much money and I really appreciate how honest and ethical they were.”

MacDougall Plumbing and Mechanical LLC
Londonderry, NH Air Conditioning and Heating Companies
Jul 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.”
A. Fagundes Plumbing & Heating Inc.
Londonderry, NH Air Conditioning and Heating Companies
Dec 28, 2017
“We have used Fagundes Pluming & Heating for the following: -3rd Floor Bathroom (Sink/Toilet/Shower) -3rd Floor Ductless (1 Unit) -2nd Floor Ductless (3 Units) -1st Floor Heating -Basement Heating -Water Heater Replacement (Tankless) I have never worked with a company that has more top notch people than Al's team. Period. Peter who comes to your house and walks you through your options Sam that runs his team and is involved in every step Sammy, Nick and Ron who are the most polite hard workers in their field Danielle in the office who holds down the fort and answers any questions you have and takes on Mass Save and the rebates Al who is absolutely involved in his business and stands behind everything that his team does. My husband and I moved into Lowell, MA from out of the area and purchased a home that we knew needed some work. Hiring a "professional" without any personal recommendations is a stressful task. At the minimum you hope the people are fair and know what they are actually doing. If I can be the personal recommendation for Al or any member of his team I would be more then happy to tell you what an amazing team he has. They are a hard working, polite and the top of their field. All their work is top notch. We liked the job they were doing and trusted Al and his team so much that we took recommendations from him for an electrician and a contractor. If you need any work done on your home at ALL you need to call Al Fagundes first. You will not be disappointed! Thank you Al and team for your amazing job in our home!”

“We hired Key Heating & Air Conditioning to be the HVAC Subcontractor for our 23-unit condominium project known as Coastal Woods located in Kennebunk, Maine. The quality of the work, the competitive pricing, the response from the technicians and the education sessions conducted by the President of Key Heating has been outstanding. We highly recommended Key Heating & Air Conditioning.”

Jul 25, 2015
“What a phenomenal company!! We had a serious leak on a Friday night. Within 15 minutes, the truck was in the driveway and problem solved. And we didn't get ripped off. As a homeowner, it's great to know you can have prompt, trustworthy, fairly priced, and courteous service when you need it. Highly recommend Steve and his team for any project, big or small.”
ET Radiant, LLC
Londonderry, NH Air Conditioning and Heating Companies
Jan 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.”
Net Zero Heating & Air Conditioning
Londonderry, NH Air Conditioning and Heating Companies
Dec 21, 2017
“I received quotes/estimates from 5 local vendors and Net Zero was the least expensive of the lot. Excellent service and will use again if needed.”
Obie Comfort Solutions
Londonderry, NH Air Conditioning and Heating Companies
May 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.”
