"Jason completed the repair of 7 Oil heaters, full blower wheel replacements, nozzle head replacements, tune up and more. For the first time in 15 years all heaters run SILENT and they are 18 feet in the air in a mechanic shop of a dealership. He then served all 5 A/C units on the roof of the dealership. Ever since we hired him it has been seamless and very fairly priced. I would highly recommend him and his company. He's always available for any emergency we've had regarding the units."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

"Excellent. Very nice man, very polite. It's nice and cool in our house. He installed it properly and it's working well."

"Extremely satisfied & pleased with the work performed by Elm. Eric, Rob & Jesse were great on the installation – on time, neat, careful to show us the status as they went through the job. Have already recommended Elm to neighbors who expressed interest. Scott was great on the initial review & estimate & Cathy in the office was extremely helpful as well. Thank you to the whole Elm Team!"

"They came as promised and solved my problem immediately would definitely recommend fair and honest"

"Varsity installed a new high efficiency gas combi boiler (heat and hot water) for our home. Working with them has been one of the best contractor experiences I have ever had in all my years of home ownership. They are very responsive, care a lot about the quality of their work, use well qualified technicians, and follow through on all their commitments. They follow up on all calls, come when they promise, get the job done and really seem to care about their reputation and work quality. They are a little bit more expensive than some of their competitors, but they are worth the price. Just to be clear - I am not a paid shill. I almost never give such good reviews, and I have been maintaining a home now for a long time."

"Kevin and Sal did a phenomenal job installing our new state-of-the-art HVAC system. This father-and-son team is incredibly hardworking, professional, efficient, reliable and accommodating. Kevin, who has worked in this business for many years and is extremely knowledgeable about energy-efficiency and environmental improvements, shares his expertise with his son, and it’s a pleasure to see them work side by side. We were referred to Kevin and Sal by our nephew, who had found them on Angi’s list when he needed a new boiler. He had told us they are customer-focused and strive to do the best possible job from start to finish—and he was right! What's more, after completing our HVAC installation right on schedule and reviewing every aspect of the new system with us, they left our home cleaner than it was before. We couldn’t be more impressed with all of their high-quality work."

"Joe responded to my online "request for quote" within an hour of me posting it. He offered to come the next morning and arrived exactly on time. He assessed within 10 minutes that a capacitor in one of our units had blown, probably due to a line surge from a lightning storm, and had a replacement capacitor in his truck. The capacitor was replaced and the repair completed in 30 minutes. He then a quick review of our entire system to assess its overall health. My experience with Joe was so good that I have asked him to send me a service contract to maintain my AC system going forward."
