Heating & Air Conditioning Contractors in Londonderry, NH
Average rating: 5 out of 5 stars24 August 2016
“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.
Heating & Air Conditioning Contractors in Londonderry, NH
Average rating: 5 out of 5 stars10 December 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.”

“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.”

Brooks & Brooks Hvac
Heating & Air Conditioning Contractors in Londonderry, NH
Average rating: 5 out of 5 stars14 December 2015
“Quick responsiveness to a lack of heat in my household. Mr Madden came inbetween his other jobs (in the area) and I was very appreciative of his time and promptness. He fixed both a lose wire and a not fully attached wall thermostat (work, by the way, done by another company who failed to respond to follow-up on their work). He even talked me through an over-the-phone attempt to mitigate the problem but when that failed his arrival soon after the call earned my respect and trust. Mr. Madden has my vote for a professional who is knowledgable, courteous and fair.”
