H & M Heating and Cooling did an excellent job installing my new heating and cooling system. From start to finish, their team was professional, knowledgeable, and easy to work with. The installation was done efficiently, and they took the time to explain everything clearly. The system is running perfectly, and I’m very satisfied with the results. I highly recommend H & M Heating and Cooling for anyone looking for reliable and high-quality HVAC service.

I had a great experience with H & M heating and cooling. Unlike others others in the market that immediately recommend replacing expensive parts. He did a diagnosis based plan to resolve the issue with carefully thinking what is right for the home. He patiently answers all My questions and explained what he was doing with fair quotes.

H&M Heating and Cooling Company saved my day. Right from the time of the first phone call, Vishnu came across as a genuine and trustworthy professional that can deliver to the promise . Our heating system went out, and had heat and hot water . When approached with an outside Heating company the Tech came up with an exorbitant quote. However, Vishnu was able to get it up and running quickly at a reasonable cost. He squeezed in time in his schedule and was accommodate the unplanned work. Professional, punctual, and very knowledgeable. I had a great experience! Highly recommend him for his expertise and service quality.

Vishnu was awesome. He was very helpful, and responded immediately when I had a furnace failure. Diagnosed the problem over FaceTime after hours and fixed it the next day. Could not have asked for a better service.

I cannot recommend H&M Heating and Cooling highly enough. Based out of Newington and serving the Greater Hartford area, Vishnu and his team are the definition of professional, honest, and skilled services. ​We recently used them for a full HVAC system maintenance (both heating and central air), and the entire experience was outstanding from start to finish. Vishnu was incredibly responsive and came out promptly to give us an estimate. What impressed me most was his honesty, he gave us a clear, detailed quote with no hidden fees and explained what we genuinely needed without trying to oversell us on things we didn't. It's rare to find that kind of integrity, and the pricing was excellent for the high quality of work and equipment we received. ​If you're looking for any HVAC work, from annual servicing and maintenance to a full installation, look no further. H&M provides exceptional service at a great price. It's fantastic value for money, and we now have peace of mind knowing the job was done right. We will be customers for life!

Very thankful to have got referred to H&M Heating and Cooling LLC by a friend after our central AC stopped working in the peak of summer this July. The first company we called gave us a wrong diagnosis with an exorbitant estimate that would have just been the beginning of a series of replacing good parts. H&M saved us a lot of money by immediately identifying the problem, got our AC running with limited control until the the right part arrived. Once the part arrived two days later (it was the beginning of the weekend when we called them), we were up and running fully and have had no trouble with our AC.
