Frequently Asked Questions

Common questions our Orange County neighbors ask about water heater repair & maintenance services

How long does a water heater usually last?

Traditional tank water heaters typically last 8–12 years. Tankless units can last up to 20 years with proper annual maintenance.

Should I repair my water heater or replace it?

If your tank is leaking, rusty, or over 10 years old, replacement is usually the most economical option. If it's a minor part failure and the unit is under 8 years old, repair is often the best choice. We'll give you an honest recommendation.

What is the benefit of a tankless water heater?

Tankless units save energy by only heating water on demand, provide endless hot water, and take up significantly less space than a traditional tank.

Do you haul away the old water heater?

Yes. Our service includes the safe removal and environmentally responsible disposal of your old unit.

How often should a water heater be serviced?

Most water heaters should be professionally serviced once a year. Annual maintenance helps remove sediment buildup, improve efficiency, extend the unit’s lifespan, and catch small issues before they turn into costly repairs.
