"Home Comfort Systems did a fantastic job with the replacement of my furnace (and my A/C five years ago). Steve is a highly reputable person and explains things easily for people not in the Heating & A/C industry. He is very straight-forward with his quote and doesn't try to pressure or scare you into purchasing something you do not need. Their 10-year labor warranty is also very impressive, and they stand behind their work. A couple of weeks prior, they were able to take a look at my old furnace right away despite having tons of calls due to the first cold snap of the year. The furnace install only took about three hours and was smooth as can be. The installer took great care in making sure floors were protected when hauling equipment in and out of the house. He also made sure to repair some ductwork that extended off the furnace. My suggestion is to make sure you call Home Comfort Systems if you need service or replacement of your furnace and/or air conditioning."

"I've been using Shavitz for maintenance on both my HVAC systems for three years, and they've been great in every aspect. Because of my trust in their work, I'm now on a service contract. A while back, Shavitz also replaced my A/C coil in one of the furnaces that failed due to the installing company's poor installation. That repair was also perfect."

"Tim and his assistant worked rapidly, but carefully, to remove the old furnace, install the new one, test it and then clean up the furnace area in the basement. In addition they were able to put the furnace-mounted humidifier back in operation. Not only was Tim and his assistant prompt, courteous and professional, they explained everything clearly and exceeded my expectations by installing a new furnace on a Sunday morning!"

"Water heater needed replaced asap. They were able to come out the following morning to provide quote and install/complete the next day. Easy, straightforward process and I appreciate only two mornings without hot water."

"Amer was absolutely top notch. He came out in 30 mins on a Saturday morning to take a look at the project- rewire barn, new panel box, pool pump set up. He then came out as the pool was being installed, on his own, to make sure it was going well and to find out info about the pump for his part of the job. He came out a few days later and completed everything perfectly, went above and beyond and made everything aesthetically pleasing. After the job was completed, he then proceeded to walk me through everything he had done and explained why, and even going so far as to explain how my home generator works (weâ re new home owners), as well as upgrade our old dingy barn lights. We already have another project set up with him in for late summer/early fall. Amer communicated wonderfully, completed the job perfectly and went above and beyond. I canâ t recommend him any higher!"

"Edward responded right away and came out first thing the next morning. It was nice watching his detective work in locating the problem; he found it and fixed it quickly. I will use him for sure next time I have a problem -- or when it's time to replace the furnace (soon)."

"These guys did a great job replacing my 25 year old furnace with a new high-efficiency one. Donnie came out and explained to me the features of the new furnaces as well as how to reduce the noise from the blower fans. My old one was deafening. He explained all of my options and then let me decide what I wanted. He quoted a good price and was true to the estimated cost. He kept me informed of the day they would come to do the job. He and his assistant worked a full day in pretty adverse conditions. (My basement has a low ceiling and is very cramped and dusty.) They never complained and worked to completion. I couldn't be more pleased with the quality of their work and their customer service. I will definitely be hiring them for future work, including a new water heater, my next project. These guys are real pros."
