Great job
The service provided by Alex was excellent. He explained everything he did in detail and taught me something about our split unit that I did not know. I would welcome him back to do our service any time.
This company provides good service… The technicians are competent, courteous and prompt… I highly recommend this company.
Brandon was able to install a PVB for my irrigation system to keep me in compliance with Federal law and I sure liberty water did not turn off my system. Brandon showed up the next day after I called, he completed the work in less than two hours. He was polite and explained what he was doing, even took the time to install extra hose bibs to ensure it was easier for me to blow out the system. I will ask for him again if I have a plumbing issue.
Prompt response and solved the problem.
Neat and tidy installation and clean up. Excellent job!
Nick was very knowledgeable & personable.
Universe is lucky ๐Ÿ€ to have such a great employee
We had a serviceman come to our house to check into our heating issues. Our burner is showing corrosion due to living near the ocean. We could either repair or replace. We are going to replace the system. The serviceman, Anthony was knowledgeable and not pushy.
This edit is in regards to a recent appt for my AC tune up. The fact that I keep getting rescheduled the day before my appt and after confirming is highly unprofessional. You also need to come up with a better response as to why you are rescheduling as your reps use the same line verbatim. Like everyone else my AC requires maintenance. I had to take days off of work to accommodate YOUR availability only to be cancelled each time, now twice! Its highly inappropriate and unprofessional. Do not bother making appts with this company!

April.2026 update. Alex came and did my tune up. He was very knowledgeable and professional. Thank you for all your time and help. Much appreciated!
Frank N was wonderful. He explained everything thoroughly.
Barney R 3 is wonderful, knowledgeable and professional person. I am very happy to work with him.
Called Universe for a maintenance of our central air. They sent Nick Samson and he did a great job. He was courteous and professional. I highly recommend both Nick and Universe. They always make good on their promises.
Bob was extremely knowledgeable and professional. Outstanding service.
I called at 1:15 in the morning due to my oil burner leaking oil. Dylan was at my home by 8:00 a.m to fix the problem. He knew what the problem was right away and fixed it. He was efficient and clean.
Jake was very professional and provided great details regarding services. I really appreciate the time and attention to details that he took.
The service was great and friendly, doesnt seem like there is any bull. A little expensive but worth it for the service.
Chester, the Universe Home Services HVAC technician, and Anthony the plumber, did an excellent job. These folks are highly recommended.
Just had new HVAC system and water heater installed by Universe home services. It was a very smooth process. Frank from sales gave us different options for installation. Explaining everything clearly. Ms. Tara answered all my follow up questions over the phone. They gave us a date for the job within couple of days of signing the contract. Keith and his crew arrived on time and explained how the process will go. They did a clean job and halled away the old equipment . Trevor the electrician inspected all the electrical work before leaving. They finished in one day as promised. I will recommend them
David was great. Explained everything that had to be done . Also gave me several options and a honest opinion. Thanks Dave
Great service!! Jason was very nice and I felt confident with the service he did and the price was very reasonable.
I will absolutely use this service again!!
Chris did a great job. Very efficient and neat.
Jamie did an evaluation of my home for the purpose of installing an HVAC Ductless system – he was very thorough and professional- I recommend him to anyone who is looking for a new system
Alex riviera was fantastic. Super knowledgeable and was a great help. Definitely recommend! Marc Thompson- comfort advisor explained our options with knowledge and patience.The installation technicians John Mahnken, Matt Drury and Bryan Fiddler did a very good job. Cleaned everything after the job.
Both Melanie and Nick very professional. Hard workers, know their stuff. Iโ€™m very happy with them and will be calling them back for more work.
We are really happy with our service contract with Universe, it keeps our systems humming and costs reasonable. They come right away and are very clean and professional. It seems all plumbers make that claim but these guys actually are.

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.
