"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 called Varsity on a Sunday night when I realized I had no hot water . It was the day we had the snow storm. The next morning Sean arrived to access the issue with my very old hot water heater. He was extremely knowledgeable and gave me my options. Within a short time Jake and Anthony joined and my new water heater was installed and working. No mess , no stress. They were amazing. Sean even shoveled the skirt of my driveway when the plows came and blocked me in as I was trying to get to work. This team went above and beyond to help any way they could. My utility room look clean and the work done right. I highly recommend Varsity. I feel comfortable knowing the technicians had the right training and were really nice guys to deal with. Thanks to Erica for taking my call so late and to Christine for getting the men out so quickly the next morning. They kept me informed every step of the way. I appreciated that."

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

"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."
