"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 needed two boilers and a hot water heater replaced. Billy and his crew did a beautiful job, everything done perfectly, neatly and quickly. I was very impressed. His fees are reasonable, no ripoff. This is a definite five plus stars. Highly recommended ."

Kept me informed throughout the entire process and quickly got me a new water heater installed in less than 3 hours at half the price, half the time and zero problems my friend had 2 months ago! I will sing their praises and will refer them forever! They left me 100% satisfied with their clean up and efficiency! Do not hesitate to use them, they are wonderful!!!"

"Used Aces on three separate occasions to replace my water heater, unclog my kitchen drain and for a frozen pipe. Both Andre and Anthony were professional and friendly. All three problems were resolved on the first visit. I would definitely call them for any plumbing problems I encounter and recommend them to friends and family ."

"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. "

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"I am very happy with the service I received from Varsity Home Service today. I was given an arrival time and the installation team showed up on time and worked neatly with respect for my home. I had two Fujitsu Air Conditioners/Heaters installed and it has changed the level of comfort in my home instantly. Kevin, Tom and Colin were friendly, engaged and did an amazing job. I barely knew they were here. Before they left they showed everything I needed to know about my new units. I highly recommend Varsity Home Service and the Fujitsu Air Conditioning Unit."
