Practice makes perfect, and Varsity has been at it for over half a century! What began with a Navy veteran’s simple dream — to teach the value of honest, hands-on work to his children — has grown into one of Long Island’s most trusted resource for plumbing, heating and air conditioning services. Varsity’s mission has always been clear: to serve our neighbors with integrity, solve home service challenges with innovative solutions, and provide lasting results. Our dedicated crew is background-checked, rigorously trained in the latest technology, and excited to exceed your expectations. Above all Varsity is here to EARN your trust—not just for today, but for years to come. Let’s tackle your home service needs with the quality and care you deserve!

"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. "

"We had an emergency after a power surge that fried our furnace. Varsity was at our home first thing in the morning. Ralph went through a thorough diagnostic process with us, went over all of our options with prices, and we ultimately replaced our entire unit. The work was done efficiently within hours. No mess to clean up afterwards, and the techs at Varsity returned our home to the safe, warm environment we needed in preparation for a large winter storm. The techs took proper precautions when entering our home, even going so far as to wearing shoe coverings to protect our floors. The service manager communicated the entire process with us before it was happening, keeping us informed every step of the way. The employees at Varsity treated our family like their family. They made our urgency their priority. Every employee we spoke with was kind, respectful, and thoroughly educated on the situation, even the customer service representatives. This company will continue to serve us through the years. They’ve earned our trust from day one."

We are a family owned and operated business with several years of HVAC experience. We pride ourselves on providing an honest and accurate quote and stand behind our work. We have outstanding ratings and provide superior customer service. Feel free to check us out and give us a call for more information.

"TLDR: safe, thorough, educational. 10/10 would call again. - My in-unit residential heater has been rattling and the filter light has been going off since I moved in (2 years). I've taken it apart (as much as I could) to do superficial cleanings, but to be safe I asked my landlord if I could find a Rinnai-certified technician to complete a professional servicing. I found Mazgan on Google and chose them due to their 4.7 rating. My landlord's initial concerns with outsourcing from the super was that companies tend to tack on hidden fees/charges. Mazgan did not do this. In advance of our appointment, Mazgan assured me that they were only booking me for a professional servicing appointment (which included opening up the unit, completing a comprehensive cleaning, and diagnostic), and that any issues found would not be addressed in that appointment but rather a 2nd appointment would be recommended if necessary. Thankfully, nothing was wrong with the unit (besides the fact that it has literally never been cleaned 🙃). Zaki, the technician, was extremely thorough. He cleaned the unit for nearly 2 hours, was very quiet and gave me a heads up when something would be noisy (which enabled me to work-from-home in peace), showed me photos of how clogged the vents were with dust/grime, and provided a lengthly and clear explanation of how the machine works and the importance of cleaning/how accidents can happen if not. They showed up when they said, charged what they said, and completed what they said. First things I did once Zaki left were to save Mazgan's number, purchase a carbon monoxide detector, and leave this review."
