Connor Tomaszewski is one of the best technicians out there and the only one who truly knows Navien boilers inside and out. His work is outstanding, and he is always professional, knowledgeable, and reliable. I highly recommend him to anyone looking for top-quality service!
We recently hired Universe for our oil to gas conversion, along with some related work. Everyone who worked on these projects was professional and a pleasure to deal with. In particular, Nikki LaCava did a wonderful job coordinating the work and assisting with our permits and other required paperwork. Brian Gerle and Hayden Muttee did a fantastic job installing the gas piping for the project, while Sal Tarantino and his crew (Hayden Muttee and Nick DiGiacomo) also did fantastic and efficient work removing our old furnace and hot water heater and installing the new equipment. Additionally, Christopher Martin did a great job fixing an interim problem with our old hot water heater before the final conversion was completed. Thanks to you all for a job very well done – each one of you deserves a five-star review! Thank you again for everything, Craig and Claudine Livingston

June 2026 The pump from my washing machine decided to stop working a few nights ago. What a disaster! Thank goodness I had the gizmo on the floor that starts beeping when water hits it because it could have been a lot worse. The water in the pump kept pouring out until it was empty. I called Universe and Melanie F. came over. She evaluated the situation and made plans to come back the following day to install a new pump. I was so impressed with Melanie. Her recommendations on the new pump worked out great. I was so pleased with Melanie's professionalism and knowledge that she's coming back soon to install the automatic water main shut off when it senses a leak. Once again I highly recommend Universe and Melanie F.! April 2026 Nick S. came to do the yearly service for my air conditioning. Nick is great and very up front which I like. After almost 17 years I need a new system. Ugh! He brought me outside and showed me all the reasons why it should be replaced. I could wait & see but didnโ€™t want to risk it so Saturday Iโ€™ll be getting a new system. It just needs to be done. I was very happy Nick explained everything to me. Heโ€™s very knowledgeable & friendly. I would also like to acknowledge the following employees from Universe who all had some part of the installation of my furnace, compressor and humidifier. Everyone who came to my house were so friendly and respectful. The guys all explained what was being done. They also installed an Air Scrubber which purifies my system of spores, etc. The employees are Tommy Ercolano, Matt Drury, Carlos Caceros, Justin Quan-Soon, Jamell Smith and Karl Rindfleisch. All were fabulous. And I can't forget Chester Sacknievich who came back to fix an issue I was having and figured out the solution. Chester is great. I highly recommend Universe. Their employees go above and beyond!!

Our water heater unexpectedly had to be replaced after National Grid identified it as a safety concern before reconnecting our gas service. Needless to say, it was a very stressful and completely unexpected situation. From my very first phone call, everyone at Universe Home Services was kind, patient, and incredibly helpful. They understood the urgency and had a technician at my home much sooner than I expected. Jeff Madonia was outstanding. He took the time to thoroughly inspect everything, patiently answered every question I had, and never made me feel rushed or like I was inconveniencing him. He explained my options clearly, walked me through the estimates on his tablet, and made sure I understood everything before moving forward. Initially, it looked like the installation might have to wait until the following morning. I asked if there was any chance it could be done the same day, and Jeff immediately went to see what he could do. A few minutes later, he came back and told me they were going to make it happen that day. That level of customer service meant so much during a stressful situation. I also appreciated how respectful Jeff was while working in my home. Even when I had left the door unlocked while he was moving equipment in and out, he always knocked before coming back inside. That level of professionalism and respect stood out to me and made a stressful situation much easier. The entire experience, from the first phone call through the completed installation, was professional, efficient, and reassuring. Jeffโ€™s kindness, knowledge, and willingness to go the extra mile made all the difference. Thank you, Jeff, and thank you to the Universe Home Services team.
I had an issue with my HVAC, and Universal was able to send someone out very quickly. Both Chester and Dawid were knowledgeable, professional, efficient, and very respectful of my home. They diagnosed and fixed the problem promptly, and the entire experience was smooth from start to finish. Thank you for your excellent service! I will definitely use Universal again in the future and highly recommend them.

I had a great experience with Universe Home Services. I initially left a message on their call system and received a call back with 30 minutes from Laurie. I explained my concern and issue we were having with out Central AC and she was able to schedule service for that same day. I received text messages with arrival time, when the technician was on their way, and when they arrived at my home. Our service technician was Bob Grillo. He was super personable, kind and very thorough in his process. He answered all my questions and explained exactly what he was doing as he was troubleshooting. I had a great experience overall with the customer service as well as the job completion and would highly recommend Universe Home Services and Bob as the technician.
Danny Sutton from Sales was amazing.without him this was not possible.so kind and empathetic towards customer amazing service From the crew who was here to install the air condition Sean Dany Jared Brian Very professional polite and extremely knowledgeable They worked so efficiently and kept the area clean that you could not feel that a big job was completed after they left. I will recommend Universe home service to everyone out there who is looking for a reliable company.

We have used Universe now for a few installations, Anthony recently swapped out a toilet for us, cleared out a major blockage on a sewer line and Vidal just installed a whole house filtration system for us after our previous system failed on our 1929 house. They have been very polite, knowledgeable and efficient and have always given us fair and tiered options with pricing. We would highly recommend their services.

Kevin came to my home, evacuated the problem and detailed the situation to me. He ordered the new ductless equipment and installed it the next day. Kevin was professional, honest, neat and made sure the air conditioning was working properly. For my air conditioning units and repairs, I wouldnโ€™t go anyplace else.
The team was incredibly professional, friendly and worked efficiently to get the job done. I had a great experience

I canโ€™t say enough good things about Universe home services and repairs. We have been a customer of Universe for years. Recently we had a plumbing issue and they were wonderful. Jeff the plumber was very professional and a pleasure to work with. We have also worked with Marc on a gas conversion. He was very knowledgeable, professional, and helpful. Great company with quality people! Update June 2026 – another 5 stars for Universe Home Services and electrician Dawid Boroch. Dawid was very professional, knowledgeable, and his work is exceptional. He explained the scope of the job and answered our questions before beginning his work and walked us through the results afterwards. Dawid was an absolute pleasure to work with and we highly recommend him!

Boiler Installation

Installing a new boiler is a significant step in making sure your home stays warm and efficient through the winter.

Universe installs boilers across Nassau and Suffolk County, sized and configured for your home’s heating needs.

Choosing the right size boiler is essential for comfort and efficiency. A system that is too small will not keep up with demand, while an oversized unit wastes fuel and wears out faster.

Modern boilers are designed to be more efficient than older models. Selecting a high-efficiency system helps reduce fuel consumption and lowers long-term heating costs.

A new boiler has to work with the piping, radiators, or baseboards already in the home. We evaluate the distribution system to make sure the new equipment integrates correctly.

Proper installation goes beyond setting the unit in place. Ventilation, clearances, gas or oil connections, and safety standards all have to be met before the boiler is commissioned.

Boiler Replacement

If your current boiler is outdated or no longer performing efficiently, a replacement improves comfort and energy use.

Universe handles boiler replacement across Nassau and Suffolk County, removing the old system and installing the new.

Newer boilers use fuel more effectively, which means more heat with less waste. That shows up as noticeable savings on heating bills over time.

An older boiler is more likely to break down or struggle to keep up with demand. A new system provides consistent, dependable heat, especially during the coldest months.

Frequent repairs add up quickly with an aging system. Replacing the boiler reduces the need for ongoing fixes and provides a fresh service life.

By far the most common upgrade we perform when it comes to boilers is oil-to-gas conversion. When we replace your boiler, we can help you evaluate whether converting to gas makes sense for your home.

Boiler Repair

Even well-maintained boilers break down and eventually reach the end of their lifespan.

Universe diagnoses and repairs boiler problems across Nassau and Suffolk County, including issues that can lead to no heat in the middle of winter. We can help with:

A sudden increase in heating costs without a change in usage indicates your boiler is working harder than it should due to an underlying problem. We identify the cause and restore efficiency.

Banging, clanking, or whistling sounds often point to air in the system, sediment buildup, or failing components. These issues are worth addressing before they become a shutdown.

If some rooms are colder than others or the system is not producing enough heat, a boiler component or the distribution system needs attention. We diagnose the full loop, not just the boiler.

A leak at the boiler, the piping, or a valve is a problem that does not get better on its own. We locate the source and complete the repair to current code.

Boiler Maintenance

A well-maintained boiler delivers consistent, comfortable warmth, operates more efficiently, and has a longer lifespan. A boiler can typically last 15 to 30 years with proper care.

Universe provides boiler maintenance across Nassau and Suffolk County.

Annual maintenance before the heating season catches wear and calibration issues before they affect performance. A tuned boiler runs efficiently from the first cold night through the last.

Over time, soot and debris build up and reduce efficiency. Cleaning the burner and heat exchanger restores performance and extends the life of the equipment.

Safety testing is a core part of every boiler maintenance visit. We verify pressure, safety controls, and combustion to confirm the system is operating within spec.

Hydronic boilers depend on correct system pressure and water level to circulate heat properly. Routine checks catch drift in either before it becomes a performance or safety issue.

Boiler FAQs

How often should I service my boiler?

We recommend having your boiler serviced once a year, ideally before the heating season begins. Regular maintenance improves efficiency and prevents unexpected breakdowns.

How long does a boiler typically last?

Most boilers last between 15 and 30 years, depending on usage and maintenance. Routine service extends the lifespan and keeps the system running efficiently across that window.

Are newer boilers more efficient than older ones?

Yes. Modern high-efficiency boilers convert a larger percentage of fuel into usable heat compared to older equipment. That shows up as meaningful savings on monthly heating bills.

Can I convert my oil boiler to gas?

Yes. Oil-to-gas conversion is one of the most common boiler upgrades we perform. We evaluate your home, coordinate the gas line connection, and install the new system end to end.
