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!

"After receiving several quotes, I contracted with Varsity to replace my aged out system. John worked the numbers with me to come up with an acceptable cost factor and worked with me on the install schedule. I needed to do it in two separate phases as I was getting other work done. The install sup reviewed the job and made recommendations tweaking the job. They removed the old units and came back a couple days later for a full day of install with a crew of five tecs. The tecs were very thorough and knowledgeable and willing to answer any questions I had to make sure I was satisfied on completion. A system check was done verifying all was good. Then they left the site cleaner than they found it. The sup reviewed my warranty and how to register my units. Varsity is worth receiving an estimate for AC install or replacement if you’re in the market."

Full service remodeling, roofing and siding contractors serving Long Island. Whether you are in need of new roof installation, roof restoration, or roof repairs; new siding installation, siding repairs; new windows & doors installation; kitchen remodeling; bathroom remodeling; we are the Long Island home remodeling contractors to call, due to our professionalism and affordability.

"The initial meeting with John was promising. He was straightforward, easy to talk to, and quickly provided a quote without being pushy. I appreciated that he offered light recommendations without trying to upsell us. After that first meeting, I felt comfortable moving forward. I had John come out one more time so my boyfriend could meet him, ask a few more questions, and finalize the siding and color choices. The next morning, John texted early, saying he’d be by within the hour to pick up the $10,000 deposit. We were told materials would be ordered right away and the project would begin by the end of the month. However, as that date approached, we hadn’t heard anything. When we reached out, we were told it would be delayed by another week — and then again, another week. We were okay with some delays, but the complete lack of communication was extremely frustrating, especially since we needed to coordinate our work schedules. We were also told the work wouldn’t involve anything on the inside, but that turned out not to be true — which was a big issue since we have two pets. During the project, our flower beds and garden were completely destroyed. While some wear and tear is expected, there was no reason for a large boxwood bush to be crushed with a cinder block when there was clearly space to work around it. Several things were damaged, including blinds, window sills, a shelf, and part of the entrance flooring. While I understand that accidents happen during construction, what bothered us most was the lack of accountability. None of these issues were addressed until we specifically called them back out to deal with them. John never showed up for a single walkthrough, and to our surprise, the entire job was done by a different company altogether — not his own crew. That was something we hadn't anticipated, and unfortunately, we didn’t think to confirm it beforehand again our fault. The windows installed were low quality and very off-brand compared to what we expected. We had also discussed having decorative grills/grid lines in the windows, which were completely left out. In the end, while everything listed in the contract was technically delivered, the overall experience left a lot to be desired. The workmanship felt sloppy, communication was almost nonexistent, and the lack of oversight from the owner was disappointing. We definitely feel we overpaid for what we received. It’s partly on us for not being more proactive during the process, but someone who takes pride in their business would have at least done one final inspection or walkthrough."

FAQs for water heater repair or service projects in Deer Park, NY

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
