"Chris replaced gas water heater, re-plumbed washing machine discharge, replaced all sink water supply valves and hoses in home and apartment. He was completely professional, on time, very good communication and did an excellent job for a fair price. I would definitely use him exclusively and I have already recommended him to others"

"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 that I hired Patience HVAC to replace my hot water heater. I have an oil burner and oil hot water heater. The 18 year old heater was making crackling noises and I was advised by the oil company to replace it. I wanted to convert to a gas hot water heater and tried going through Lowes. However, they only do swap outs if the existing heater is already set up for gas. So I contacted several companies for a quote. Out of all of them, Anthony was the most professional, down to earth and reasonably priced. First, he suggested to explore correcting the issue on the old heater and save me money which was impressive. I decided to proceed with a new gas heater. The quote he gave me was $800 less than the next lowest quote. Anthony sent his workers Caesar and Matt the next day which I greatly appreciated. They were both very polite and wore covers on their shoes so to avoid dirtying my house more than necessary. Anthony came later in the day to ensure everything was done correctly. He then offered to call him with any questions even if they were not pertinent to the work they performed. I am extremely impressed with patience HVAC honesty, professionalism and reasonable prices. I will be sure to recommend them to friends and family. When I am ready to install a ductless air conditioner, I will definitely contact Patience HVAC."

"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."
