    "Had an excellent experience. He replaced my boiler and water heater and did a flawless job from start to finish. Super professional, showed up on time, explained everything clearly, and the work was clean and efficient. The new system runs perfectly, and the installation looks great. Pricing was fair and there were no surprises. It’s hard to find tradespeople this reliable—highly recommend and would 100% use him again."

    "I am not a dramatic person, but Cole is a godsend!! He was on time and diagnosed and fixed our issue quickly!! He was friendly, professional and BRILLIANT. Don’t let his young age fool you. This guy knows what he’s doing. My mom’s front porch light blew out from an overzealous space heater. And it wasn’t just the front porch light. None of the outlets on the entire front wall of the house were working! Thank you, space heater. So we saw the great reviews for Cole and decided to call him. BEST. DECISION. EVER. Cole arrived ON TIME and found the issue almost immediately. If you saw my mom’s house (bless her heart) you would know this was no easy feat. So thank you, Cole, for smashing the stereotype of the expensive electrician who milks the clock. You are, and always will be, our first call for all of our electrical needs. From the bottom of our hearts, thank you!!"

    "Really happy with the GREE mini-split heat pump system installed by Elite Heating and Cooling. They had the best prices for the same units others quoted me higher for, so big thumbs up for value. The team was super professional with the documentation and communication. Plus, they got it all done right on schedule, which was a huge relief. Definitely recommend them if you are looking to get HVAC work done without any fuss or over-spending."

    "Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

    "My name is Irving Francis. I got in touch with Professor Pipes when my radiators got clogged in my house. After paying $225 to another techy from another company who claimed I needed new bleeders and getting the run around by 3 others so call heating experts.Professor Pipes reached out to me and I told him the problem and Mike diagnosed it as a simple line bleed. He fixed the problem and Im sitting in a nice warm home tonight. I highly recommend Professor Pipes to anyone having a heating problem. Mike is honest and fair when it comes to pricing. I highly recommend Professir Pipes."

    "Billy and his crew were an absolutely pleasure to work with. They exceeded my expectation to replace my boiler and hot water heater along with associated piping in record time working in concert with the GC to complete all work in 3 days. The finished work was neat and clean correcting errors with my original installation. All debris was removed each day. He ensured I was satisfied, kept me informed of the progress and what to expect. Upon leaving he made recommendations to have all my air valves replaced in my radiators and encouraged me to call with any questions. I appreciate the care he and his crew took with my home."
