Amazing experience! Before i bought my house Universe had installed two mini splits.This is a large company that stands by its work. Joanne navigated me through the permit process. She answered all of my questions. Scheduled all of my appointments and even sent an electrician to make sure I was up to code and that it would pass. The electrician Jimmy that showed up was friendly, professional and on time. He worked with me when it came to scheduling. He corrected an issue so I would be able to pass inspection and helped label my circuit breaker correctly. When he was done I didn't even know he was there because he left his work area very clean. They even had someone come to my house when the town was doing its final inspection. This made everything go smoothly.I highly recommend this company. It was a pleasue working with every person that I had to deal with.

Very professional and honest. Justin took tge time to explain the problem and provided several options that I can choose from. I felt really comfortable with my decision.
Marc came out to go over our options for adding central air or a hybrid ductless system. He took the time to walk through the entire house, inspect everything thoroughly, and explain all of our options in a way that was easy to understand. He was incredibly friendly, even taking the time to interact with our dog, which we appreciated. After the walkthrough, he sat down with us and carefully explained each system, even drawing a diagram to help us better understand how one of the options would work. We absolutely loved working with Marc and could immediately tell how knowledgeable and experienced he is. We never felt rushed and left the consultation feeling informed and confident about our next steps. Highly recommend!

With a plumbing emergency on a Saturday, finding a good plumber is impossible…. except for Universal Home Services. From the time I called to Brian's arrival was less than 30 minutes. He immediately put me at ease and knew exactly what needed to be done. I had a washing machine delivered but during installation, a pipe snapped and they were not qualified to fix it. Brian fixed everything within 20 minutes, then installed the washing machine and stayed to run through a cycle to make sure everything worked perfectly. Some might say the price was high but for a Saturday emergency….. and so promptly and efficiently, I can't complain.
The technician was very knowledgeable and helpful

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.
