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 hired a pro to fix my heating issue and the tech came 2 days and couldn't resolve the issue . Charged me $100 day one for the visit and charged me $165 day two for a part that was replaced which was working fine. The issue was not with that part and pro replaced it with no reason. Spend couple of hours day two without any resolution . Today I hired a licensed installed and he came and fix the problem within 3 hrs . I wasted 2 half day of my time and also $365"

"We had an ac unit put in two years ago. It never worked quite right. He came to check situation a couple times last summer - being it was a new unit - said to leave on auto/70 and should be fine. Still would not work correctly, hot days wouldn't work at all. This year was not working at all, only HOT air would come out. Once again came this summer, added more freon, stating there must be a leak somewhere. They couldn't find leak, told us we need to replace all the copper piping to fix the not even found leak. Wanted to charge insane amount money to fix a recent unit they installed that never worked in the first place! I tried calling the business a few times with not a single call back to speak with me. Thankfully i was forced to get it checked by someone else - it was an EASY fix! The flares were never tightened and there was a welded area that we were never told was done in first place. Do not trust this place; horrible customer service, unreliable, and afraid i was almost scammed!"
