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.

Our Tankless Water Heater Services

Tankless water heaters heat water on demand, which means endless hot water and no stored tank taking up basement space.

At Universe Home Services, we offer comprehensive tankless water heater services across Long Island, with the same licensed plumbers and same-day availability as our standard tank work.

We help you find the right tankless unit to meet your household’s demand, then professionally install and test it to confirm it is working correctly before we leave.

Whether it is a leak, an ignition issue, or a heating problem, our skilled plumbers diagnose and repair tankless water heater issues across Nassau and Suffolk County.

When an existing tankless unit has reached the end of its service life, we help you choose a new system and handle a seamless replacement that keeps downtime short.

Tankless maintenance includes flushing the unit, cleaning or replacing filters, and other tasks that keep the system efficient, prevent issues, and extend its service life.

Signs You Need to Replace Your Water Heater

Sometimes a few simple repairs are enough to get a water heater back up and running, and sometimes replacement is the right call.

Call Universe Home Services at the first sign of trouble and we help you determine which direction makes sense for your home. Waiting on a failing water heater can turn a planned replacement into a plumbing emergency. We can help with:

Age is the most reliable predictor of water heater replacement. Most tank water heaters reach the end of their service life between 10 and 12 years, and a unit in that range showing any other warning signs is a strong replacement candidate.

A water heater that keeps needing service is usually telling you something bigger is coming. When repair costs start adding up, replacement is often the more economical choice over the long term.

A tank that used to meet the household’s demand and now falls short has usually lost capacity to sediment, corrosion, or a failing heating source. Efficiency decline is often a leading indicator of a tank reaching the end of its service life.

Water at the base of the tank is rarely a problem that waits. Once the tank itself is leaking, repair is typically off the table, and replacement is the path forward.

How Often Should You Flush a Water Heater?

Most water heater manufacturers and plumbers recommend flushing a water heater once a year.

Over time, water heaters build up sediment, calcium, and minerals in the bottom of the tank. These can keep the unit from properly heating the water and cause leaking from the base of the tank. Annual flushing prevents that buildup and avoids the problems that come with it. Nassau County’s hard water makes the case for annual flushing even stronger.

Sediment settles at the bottom of the tank and insulates the burner or heating elements from the water above it. The unit ends up working harder for less hot water, which shows up as higher utility bills and shorter service life.

Minerals that sit at the base of the tank accelerate corrosion on the interior of the tank and the anode rod. Flushing removes the accumulation before it starts eating away at the tank itself.

Tankless water heaters benefit from periodic descaling, which removes the mineral buildup that can restrict flow and reduce heating efficiency. We handle tankless flushing as part of routine maintenance.

Our Home Comfort Club membership includes annual water heater flushing as part of the plumbing inspection, which keeps the system on the maintenance schedule it needs without the homeowner having to remember to book it.

Water Heater FAQs

How long does a water heater last?

Tank water heaters typically last 10 to 12 years. Tankless water heaters often last more than 20 years with proper maintenance. Water chemistry, usage patterns, and maintenance history all affect the actual service life.

Should I choose a tank or tankless water heater?

It depends on household size, hot water demand, available space, and budget. Tankless water heaters offer longer lifespan and efficiency gains, while tank water heaters have lower upfront costs and straightforward installation. We help homeowners weigh the tradeoffs during the consultation.

What water heater brands does Universe service?

We service all major water heater brands, including Bradford White, Rheem, A.O. Smith, and more. We have the tools and expertise to install, repair, or tune up most major makes and models.

How do I flush a tankless water heater?

Tankless flushing involves turning off power and water, closing the isolation valves, connecting hoses to the service ports, running a descaling solution through the unit, flushing with clean water, and restoring power and water. Most homeowners leave this to a licensed plumber as part of annual maintenance, since doing it correctly protects the manufacturer warranty.
