Water Heater Installation, Repair & Maintenance
Gas, electric, tank, tankless and heat pump water heaters for homes and businesses in Montclair and nearby Inland Empire cities, 24 hours a day.
Which type of water heater is right for you?
There's no single best water heater. The right one depends on how much hot water your household uses, what fuel you have, and how long you plan to stay. Here's how the four main types compare in a typical Inland Empire home.
| Type | Typical life here | Approx. yearly energy cost* | Best for |
|---|---|---|---|
| Gas tank | 8–12 years | About $440 | Most homes; lowest upfront cost |
| Electric tank | 10–13 years | About $1,420 | Homes without gas |
| Gas tankless | 15–20 years | About $300 | Larger families, endless hot water, saving space |
| Heat pump (hybrid electric) | 10–15 years | About $380 | All-electric homes, garages, rebate seekers |
*Rough estimates for a family using 64 gallons of hot water a day at 2026 rates (Edison about 34.5¢/kWh, SoCalGas about $2.10/therm). See our water heater guide for the details.
Repair or replace?
We'll always tell you which one makes sense, and why. As a rule of thumb:
- Repair when the unit is under about 8 years old and the problem is a part: a thermostat, gas valve, igniter, thermocouple, heating element or relief valve.
- Replace when the tank itself is leaking, the unit is 10–12+ years old, or repairs are adding up. A leaking tank can't be repaired.

Questions we hear a lot
How long do water heaters last in the Inland Empire?
Most tank water heaters here last 8–12 years. Hard water builds sediment in the tank, and garage heat in the summer wears on parts, so tanks often fail sooner than the national average. Tankless units typically last 15–20 years with regular descaling.
How long does a water heater replacement take?
Most tank-to-tank replacements are finished in a few hours. Converting from a tank to tankless, or adding a heat pump unit, can take longer because of new venting, gas or electrical work.
Do you work on all brands?
Yes. We're factory-authorized by A.O. Smith and service every major brand, including Rheem, Bradford White, Rinnai, Navien, Noritz and Takagi.
