I would give this place a 5 +. From the estimate to the install, everything went exceptionally well!! Our first contact was with James R for an estimate. Instead of just providing an estimate for a new heating system he discussed what our needs were and also thoroughly explained our options and what would be best with our circumstances! The system he said would be best was indeed the best and he explained why a more costly option I had read about would not work for us. The installation crew was just as helpful, knowledgeable and professional. They left everything cleaner than when they started and removed all the debris from the old system and even an old water heater another company had left behind. When the next day the thermostat was not working properly James R came back and fixed it and reprogrammed it according to our current needs!!! This is an absolutely Outstanding Company from start to finish!!!!!

Pat was great. He rewired our thermostat and ran the wire from the basement to outside, up to our attic, and down to the thermostat to avoid putting holes in our ceiling. And he hid the wires outside under corner caps so they can’t be seen. He worked quickly and the price was reasonable.

Advantages of Gas Water Heaters

Gas water heaters deliver benefits that standard electric models cannot match, especially in homes with existing gas service.

Standard and tankless gas water heaters both take advantage of natural gas for faster heating, lower operating costs, and continued operation during power outages.

Gas water heaters heat water faster than electric models, which means quicker recovery times and a steady supply of hot water for busy households that run multiple fixtures at once.

Natural gas typically costs less than electricity on a monthly basis for water heating, which means a gas unit often costs less to run over time and shows up as lower utility bills across the life of the system.

Standard gas water heaters do not rely on electricity to operate, so they continue to deliver hot water when the utility goes down. That matters on Long Island, where nor’easters and summer storms can take the power out for extended stretches.

If your home already has a gas line, installing a gas water heater is typically quick and less disruptive than you might expect, especially when replacing an existing gas unit with a new one of the same type.

Signs You Need a New Gas Water Heater

Most gas water heaters last 8 to 12 years, and the unit usually tells you it is nearing the end of its service life before it fails completely.

Recognizing the signs of a failing water heater helps you replace it on your schedule instead of during an emergency.

Unusual noises during operation typically indicate sediment buildup at the bottom of the tank, which reduces efficiency and stresses the burner. A quiet water heater that has started making noise is telling you something has changed.

Water at the base of the tank, at the fittings, or from the relief valve points to either a plumbing-side repair or a tank failure. A leaking tank is rarely something to defer, and confirming the source quickly is how a small repair stays small.

Hot water that runs out faster than it used to, takes longer to recover, or arrives at an inconsistent temperature points to a failing burner, a worn thermocouple, or sediment that is insulating the tank from the heat source.

Rust-colored or cloudy hot water usually means the tank’s interior is corroding or the anode rod has failed. Once corrosion reaches this stage, replacement is typically the right call.

Other Types of Water Heaters

If you are considering a switch from gas, Universe installs and services electric and tankless water heaters across Long Island, Rockland County & Bergen County.

Gas is the right answer for many homes, but electric and tankless systems have their own advantages that may fit your home better depending on your hot water demand, fuel availability, and installation space.

Electric water heaters are a strong option for homes without a gas connection or for homeowners who want to avoid combustion equipment entirely. We handle electric water heater installation, replacement, and repair across Long Island, Rockland County & Bergen County.

Tankless water heaters heat water only when you need it, which means endless hot water and no stored tank taking up basement space. Tankless is available in both gas and electric configurations, and we help homeowners evaluate which fits the home’s demand and infrastructure.

Gas Water Heater FAQs

How long does a gas water heater last?

A gas water heater typically lasts between 8 and 12 years, depending on maintenance and water quality. On Long Island’s hard water, scale buildup inside the tank shortens that life at the bottom of the range, which is why we recommend periodic flushing for standard tank units.

How do I turn off a gas water heater?

To turn off a gas water heater, set the thermostat to off and shut off the gas supply valve near the unit. If you smell gas or have any other safety concern, leave the home and call the gas company and a licensed plumber.

Does a gas water heater need electricity?

Most standard gas water heaters do not need electricity to operate, which is why they continue working during power outages. Some newer models use electricity for ignition or digital displays but still operate through short outages on their own.

How can I tell if I have a gas or electric water heater?

Check for a gas line and burner at the bottom of the unit. If you see a gas line running to the unit and a burner assembly underneath, it is a gas unit. If there is no gas line and you see heating elements with a power cord instead, it is electric.
