Your Boiler Works Hard All Winter. Universe Keeps It Ready.

A boiler that gets serviced every year is one you do not have to think about when the temperature drops.

Boiler maintenance on Long Island belongs to technicians who know hydronic heating systems and what a Nassau County winter asks of them. Universe Home Services has been doing that work since 1954.

A Local Partner to Maintain Your Boiler

A boiler is the quiet workhorse of the home, and homeowners who maintain it want a local company that treats the annual visit with the same care.

Universe has been the boiler company for Nassau and Suffolk County households for decades, across every fuel type and configuration found in these homes.

A maintenance visit with Universe looks like a technician who arrives on time, moves through the mechanical room without disrupting your day, and leaves you with a clear picture of where the boiler stands heading into winter. The annual rhythm stays simple because the company handling it makes it simple.

What Consistent Boiler Maintenance Delivers

A boiler that is serviced every year performs differently than one that is not. The difference shows up in your heating bills, your comfort, and how long the system lasts.

A boiler running on a fouled burner, a partially blocked heat exchanger, or a circulator pump losing efficiency cannot distribute heat the way it was designed to. Rooms that have always been slightly cold get colder. The thermostat takes longer to satisfy. Annual maintenance keeps every component performing at spec so your home reaches temperature and holds it.

A boiler that is burning fuel cleanly and moving heat effectively through your baseboards or radiators uses less fuel per BTU of output than one that is fighting against buildup, wear, or calibration drift. On Long Island, where heating oil prices and gas rates are among the highest in the region, that efficiency difference adds up across an entire heating season.

A pressure relief valve showing early wear. A circulator pump that is running louder than it should. An expansion tank that has lost its charge. None of these cause a breakdown the day they are found. Left unaddressed, all of them eventually do. A maintenance visit is when a technician is looking specifically for what is developing, not just what has already failed.

Consistent maintenance reduces cumulative wear on the components that carry the most load: the burner, the heat exchanger, the circulator. A boiler that has been serviced annually arrives at year 20 in better condition than one that has not. The difference between a system that needs replacement at 18 years and one that runs reliably to 28 is often maintenance history.

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!

Why Nassau and Suffolk County Homeowners Trust Universe With Their Boiler

Boiler work requires a technician who knows hydronic heating systems specifically, and not every HVAC company does. Universe has been servicing boilers across Nassau and Suffolk County since 1954, and the technicians who handle boiler service understand what Long Island winters demand from hydronic equipment.

Gas boilers, oil boilers, cast iron systems, steam systems in older homes: Universe technicians have serviced all of it across Nassau and Suffolk County. The older homes on Long Island run unusual configurations, and your technician has encountered them before.

A significant share of Nassau County homes still heat with oil. Oil burner service requires specific knowledge: combustion analysis, nozzle and electrodes, heat exchanger inspection, flue condition. Universe technicians perform complete oil burner tune-ups as part of annual maintenance, not as a separate service.

Universe is a BBB Accredited Business that has been doing boiler and plumbing work across Long Island since 1954. Boiler maintenance is not a seasonal add-on. Hydronic heating has been part of Universe’s service in these homes for decades.

If your circulator is in good shape, you hear that. If the expansion tank has another season in it, it stays. Your technician tells you what the system actually needs, explains why, and lets you decide. Universe does not manufacture urgency around components that are not failing.

Boiler maintenance sometimes surfaces related issues beyond the heating system: a zone valve tied to electrical wiring, a plumbing connection at the system drain, or an exhaust flue concern. Universe handles electrical, plumbing, and HVAC in-house. When a maintenance visit turns up something outside the boiler itself, one call is still all it takes.

Other Boiler Services Universe Handles Across Long Island

Maintenance keeps your boiler running. These are the other boiler services Universe handles across Nassau and Suffolk County.

When a boiler fails or loses performance, Universe diagnoses the cause and repairs it. Pressure issues, ignition failures, zone problems, and circulator pump failures are all within scope.

Boiler repair requires a technician who knows hydronic systems, and Universe has been doing this work in Long Island homes for decades, including 24/7 emergency service when a boiler fails mid-winter.

When repair costs approach replacement value or a system has reached the end of its service life, Universe manages the full replacement. Removal of the old system, installation to code, and full startup and balancing.

For Nassau County homeowners still on oil, replacement time is the practical moment to evaluate oil-to-gas conversion, and Universe handles the full scope of that work as well.

A significant share of Nassau County homes still heat with oil, and oil boilers require service beyond what a standard gas boiler tune-up covers. Universe technicians handle complete oil boiler service including burner tune-ups, nozzle and electrode replacement, combustion analysis, heat exchanger cleaning, and flue inspection. When a homeowner is ready to evaluate converting from oil to gas, Universe handles the full conversion scope as well.

Cooling is the other half of the year on Long Island, and boiler households still need reliable air conditioning through Nassau and Suffolk County summers. Universe handles central AC installation, repair, maintenance, and replacement across the region, along with ductless mini splits for homes without existing ductwork. One company covers both the heat that carries you through winter and the cooling that carries you through summer.

A boiler is one part of a whole HVAC system. Universe handles heating and cooling across Nassau and Suffolk County, including central AC, furnaces, heat pumps, ductless mini splits, and the controls that tie the system together. When it is time to evaluate the rest of the home’s comfort equipment, one company covers the full scope.

Boiler Maintenance Questions

How often should a boiler be serviced?

Once a year, before the heating season begins. For oil boilers, annual service includes a full burner tune-up: nozzle and electrode inspection, combustion analysis, and heat exchanger cleaning. Gas boilers require less intensive burner service but still benefit from annual inspection of the heat exchanger, controls, expansion tank, and circulator. Scheduling in late summer or early fall puts the system through service before it is needed.

What does a boiler tune-up actually include?

For an oil boiler, a tune-up covers the burner assembly, nozzle, electrodes, combustion analysis, heat exchanger inspection, flue condition, and controls. For a gas boiler, it covers the burner, heat exchanger, venting, expansion tank, pressure relief valve, circulator, and zone controls. Universe technicians also inspect the distribution system for air pockets, corroded zones, and balance issues that affect how well the boiler heats the home.

My boiler seems to be working fine. Do I still need annual service?

Yes. The components most likely to cause a mid-winter failure: the pressure relief valve, the expansion tank, the igniter. None of them give visible warning before they fail. A boiler that appears to be working normally can have developing issues that only surface under sustained load during cold weather. Annual maintenance is what catches those before they become an emergency.

How does Long Island’s hard water affect my boiler?

Nassau County water has high mineral content. Over time, scale accumulates inside the boiler and in the distribution piping, reducing heat transfer efficiency and increasing wear on the system. A maintenance visit includes checking for scale-related issues and evaluating whether water treatment makes sense for your system. Homeowners on particularly hard water may benefit from a water treatment solution that protects the boiler and extends its life.
