Common Water Heater Questions
Frequently Asked Questions About Water Heater Services
Find quick answers to the most common questions we hear about water heater repair, replacement, and installation.
How long does a typical water heater last?
A traditional tank water heater generally lasts between 8 and 12 years with proper maintenance. Tankless water heaters can last up to 20 years or more. Regular maintenance and timely repairs help extend the life of your unit.
What are the signs that my water heater needs to be replaced?
Common signs include age over 10 years, rust colored water, strange noises, leaks around the tank, inconsistent water temperatures, and rising energy bills. If you notice any of these, we can help you determine if repair or replacement is the better option.
Should I choose a tank or tankless water heater?
Tank water heaters are typically more affordable and easier to install, while tankless water heaters offer endless hot water and better energy efficiency. The best choice depends on your budget, household size, and hot water usage. We can help you evaluate both options.
How often should I have my water heater maintained?
We recommend professional maintenance once a year. Annual maintenance includes flushing the tank to remove sediment, inspecting the anode rod, checking pressure relief valves, and testing heating elements to keep your system running efficiently.
