"Rene and Maurico installed a new air conditioning unit in my home. They negotiated fairly and were responsive to my questions. A team of five arrived for the installation. They worked together like a well tuned machine. Everyone knew what they had to do and when to do it. There were no mistakes. They were here by 8:00 am and were finished by 4:30. They answered all my questioned and responded to my phone calls. They were polite and respectful. They cleaned up after themselves and left nothing damaged. More companies should operate like them. I would highly recommend them"

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."

Since 1954, Universe Home Services has been proudly serving the Nassau County community and customers throughout the entire region. With Universe Home Services, one call solves it all! Their highly trained technicians offer everything from heating and air conditioning to plumbing to appliance repair and electrical services on Long Island and beyond. Whether you are dealing with an inefficient heating system, a noisy air conditioner, clogged toilet, broken dishwasher, or outdated electrical service panel, you can get the fast, affordable service you need with Universe Home Services. They go above and beyond to ensure that you are completely satisfied with the quality of their work, offering service guarantees and parts and labor guarantees on new HVAC installations.

"Over the weekend, my heater failed, and because I had previously used Universal Home Services, I called them again in good faith, expecting honesty and fair treatment. Instead, I was met with a shocking display of greed and predatory pricing that the public absolutely deserves to know about. The technician diagnosed the issue as a faulty circuit board. When I asked for the repair cost, I was told it would be $1,100 for the part alone, plus additional labor charges. My eyes nearly popped out of my head. Something felt off, so I did my own research while the tech was still here, and I discovered the exact same part retails for approximately $170. That's not a markup, that's exploitation. I confronted the technician about the outrageous price and immediately declined the service. I fully understand companies need to make profit, and I respect the value of skilled labor. But charging nearly seven times the cost of a part, without transparency, justification, or any attempt at fairness, "

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 56 years of exceeding customer expectations. All Weather provides sales, installation, service and maintenance of residential and commercial heating, air conditioning & water filtration systems.

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

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."
