Universe responded promptly to my service call and the technician was very friendly and knowledgeable. We had to wait a few days for the parts, but when it arrived (new sewage ejector pump) the repair was done quickly and everything worked perfectly.

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.

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

Water Heater Brands We Service

Universe installs and services top-of-the-line products from the industry’s most trusted water heater brands.

Whether you need fast repairs or a new installation, we have the tools and expertise to install, repair, or tune up most major makes and models.

Bradford White is widely regarded as one of the most reliable residential water heater brands on the market, with a reputation for durability and long service life in both standard and high-efficiency configurations.

Rheem manufactures a full range of tank and tankless water heaters for residential use, including gas, electric, and high-efficiency models that fit a wide variety of Long Island homes.

A.O. Smith offers residential water heaters across the full spectrum of fuel types and configurations, with a strong presence in both standard tank and tankless categories.

We service water heaters from other major manufacturers beyond the brands listed above. If you have a unit from a brand we have not named, contact us and we will tell you whether we cover it.

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.
