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!

"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."

"I called Jim for a frozen pipe, and I’m so glad i did. They responded quickly, diagnosed the issue right away, and had it repaired before it caused any further damage. The plumber was professional, courteous, and took the time to explain what caused the problem and how to prevent it in the future. Fair pricing and great service - highly recommend."
