"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."

Ron came in, accessed the situation and installed an entirely new system in 3 days at a very fair price I would trust him completely with any heating or air conditioning issues. He is beyond trustworthy"

"Pristine Air Heating & Cooling gave me direct answers to my questions including price. There were no games with them. I had my boiler replaced in the SAME DAY! They also cleaned up behind themselves I couldn't tell that they were even there. I'm definitely calling them in the summer time for my central air to be installed."
