When your water heater starts leaking, stops heating, or just isn't keeping up with your household's demand, AJM Plumbing & Heating is your South Shore solution. We install and service both tank and tankless water heaters across Rockland, Quincy, Braintree, Hingham, Weymouth, Scituate, and all surrounding communities.

Tank Water Heater Installation & Repair

Traditional tank water heaters are the most common choice for South Shore homes. We carry and install top brands including Bradford White, Rheem, and A.O. Smith. Every tank water heater installation through AJM includes:

  • 10-year manufacturer warranty on the unit
  • 2-year parts & labor warranty through AJM Plumbing & Heating
  • Full removal and disposal of your old unit
  • Code-compliant installation with all required permits
  • Same-day or next-day availability in most South Shore areas

Tankless Water Heater Installation

Tankless (on-demand) water heaters heat water only when you need it — eliminating standby heat loss and delivering endless hot water. They're more energy efficient and last significantly longer than tank units. AJM installs Navien and Rinnai tankless systems with exceptional warranty coverage:

  • 15-year heat exchanger warranty
  • 5-year parts warranty
  • 2-year labor warranty through AJM
  • Expert sizing and installation for your home's specific demand
  • Available for natural gas, propane, and electric applications

Water Heater Repair

Not sure if you need a repair or a full replacement? We'll give you an honest assessment — no upsells. Common water heater problems we fix across the South Shore include:

  • No hot water or insufficient hot water
  • Leaking tank or pressure relief valve
  • Discolored or rusty water
  • Unusual popping, rumbling, or banging sounds
  • Pilot light issues on gas units
  • Tripped circuit breakers on electric units

If your water heater is under 10 years old, repair is often the right call. If it's older or failing repeatedly, replacement usually makes more financial sense. We'll tell you honestly which path is right for your situation.
