I called Steve after a lightning strike caused damage to the control board on my air handler. Steve and Mike came to the house, diagnosed the problem and within one hour returned with a replacement part and fixed the issue. Very responsive, polite and professional.
I strongly recommend Steve Buy Heating & Cooling. I started using Steve last year for AC issues. Steve is dedicated, professional and courteous. He always responds to me immediately..(which is unheard of in the Lakes Region).Steve will be replacing our entire AC system in the fall. I trust his pricing, knowledge and I am extremely pleased with the quality of work Steve provides.
We have hired Steve Buy when we built our house three years ago. Steve was very professional then and recently we had to make a call for our furnace not performing properly during that very cold spell. Of course Steve came by with his helper and a very timely fashion. Diagnosed and fixed! Beautiful! Thank you two for your hard,professional work. We love you! Kindly, Anita& Steve Fuchs
1 star is too many. In an effort to support a local business we called Steve Buy. Steve came out on Nov. 16 th and took the time to go over what we needed in a new heating system and hot water heater. When he left he said he would have the numbers to us in a few days. It is now Jan. 8th and we are still waiting! So much for his word. If he was not interested in the job he should have just said so. Now not only will he not get a good reccomendation he gets a HUGE THUMBS DOWN. We went with another local contractor and are very happy with the FINISHED product.
Using Steve Buy Furnace was an excellent experience for me. It's hard to get people up to Sandwich, NH, but Steve was willing to come even though it meant fitting me into his schedule which was already pretty full. For comparison, the only other business that was able to respond to my call would only have been able to schedule me an "emergency" appointment. In three days. On the call, Steve was extremely professional and knowledgeable, explaining exactly what I needed to know at an inexpensive price an excellent follow-up. I cannot recommend him enough. Best experience I have had since moving to NH.
