    I just had a new furnace installed by Top Comfort Heating and Cooling. I almost canceled the free in person estimate and go with another company that had given a competitive quote. HOWEVER, i decided to go through with the visit anyway. Joel came by and was very professional, easy going, informative and punctual. He just felt trustworthy and honest to me. I explained all that i wanted and did not want. Nothing was an issue. 2 other companies wanted me to get a furnace and A/C which i did not need. He gave me an estimate that was about $700 less than the company i was going to choose..Now i wondered how far out they were scheduling installs.Joel came yesterday around 1030am . By 1:30 today, my new furnace and thermostat are in.and working. The install team of Chris ( lead installer).and his associate Mark.were outstanding. I am big on professionalism, respect and manners. They excelled in all 3 not to mention the speed of work. I tipped them moreso because of the type of professionals they were. I always like to encourage/ reward good work, especially from young men and women. I fully expect that this company will stand by their product. I thoroughly recommend them and will have them install an air conditioning unit when needed. Kudos to Joel and his company.

    I had to get someone to checky boiler, expeditiously before turning it on for the winter months. I was able to schedule an appointment with Top Comfort Heating and Air Conditioning. My service person Joel was nice, courtesy and knowledgeable about my boiler. He checked it and everything was good. He was also able to measure the space in one of my bedrooms for a new radiator. I highly recommend this company, for your heating needs.
