Water Heater Installation & Replacement

A water heater is one of the hardest-working appliances in your home — it runs every single day, often for a decade or more, and you rarely think about it until the hot water runs out or you find a puddle on the basement floor. When that day comes, replacing it promptly with the right unit, sized correctly and installed properly, restores reliable hot water and protects your home from the kind of water damage a failing tank can cause.

Quality Home Heating & Air has installed and replaced water heaters across the South Shore and South Coast since 1988. We install gas and electric tank water heaters, including high-efficiency models, and we'll match the unit to how your household actually uses hot water — not just swap in whatever size happened to be there before. Every installation is done to code, with proper connections, venting, and safety devices, and tested before we leave.

Most homeowners call us because an aging tank finally started leaking, hot water is running out faster than it used to, or repair costs no longer make sense on a unit well past its prime. Whatever brought you here, we'll give you honest options — including a high-efficiency tank or, if it's a better fit for your home, a tankless system — and we offer flexible financing so a sudden water heater failure doesn't have to strain your budget.

Tank water heaters typically last 8–12 years. Over time, sediment from our local water settles to the bottom of the tank, where it bakes onto the heating surface — that's the popping and rumbling you hear, and it forces the unit to work harder and burn more energy to deliver the same amount of hot water. Once efficiency drops and the tank is well into its second decade, you're usually paying more to run a unit that's nearing the end of its life.

The bigger concern is corrosion. The sacrificial anode rod inside the tank protects the steel from rusting, but it wears out over time. Once it's gone, the tank itself begins to corrode from the inside out — and a leak from the tank body (not the fittings) can't be repaired. When the steel fails, replacement is the only fix, which is why a leak at the base of the tank means the unit needs to come out before it causes water damage.

Sizing and demand matter too. A water heater that was fine when the house had fewer people, or before an addition or a new soaking tub, may simply be undersized for how you use hot water today. If you're consistently running out, the answer is often a larger tank or a higher first-hour rating — not nursing the existing unit along.
