Expert Water Heater Replacement in Long Island, NY

When your water heater starts leaking, producing rusty water, or struggling to keep up with your household, it is time to call A. Monte Services Corp. for water heater replacement on Long Island. We assess your current unit, help you choose the right replacement based on your home's fuel source, available space, and household demand, and handle all gas, electrical, and plumbing connections correctly. Long Island's water supply draws from the Magothy and Upper Glacial aquifers. That water is naturally soft but slightly acidic, which accelerates anode rod corrosion inside tank-style units. Many older Nassau and Suffolk County homes also lack current venting or expansion tank setups that code now requires. We account for both during every installation. Whether you are replacing a standard tank unit in a basement utility room or upgrading to a tankless system in a tighter space, we size the unit to your home and install it to New York State and county code. Call A. Monte Services Corp. to schedule your water heater replacement on Long Island.

Our boiler stopped working on a weekend and they came out without hesitation. It is rare to find a company that actually shows up when you need them most.

They installed a whole-home water filtration system and walked me through exactly how it works. You can tell they genuinely care about the job and the customer.
