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 polite, courteous and professional. Dawid gets a two thumbs up.

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.
