Should You Repair or Replace?

A key factor is the age of your current unit. Many hot water heaters last around 10 years, and older tanks can carry a higher risk of failure. If your unit is nearing that point, it may be time to compare repair costs against replacement options.

GOOD TO KNOW

In some cases, home insurance companies may not cover damage caused by an older water heater. It is worth checking with your insurer and asking what warning signs to watch for.

water heater options we install

The best water heater depends on your home’s layout, venting, and how much hot water your household uses at the same time.

conventional water heaters

A dependable option for many homes using a standard tank setup.

Power Vent Water Heaters

A strong option when venting requirements differ from a natural draft setup.

Tankless Water Heaters

On-demand hot water without storing gallons in a tank

Electric Water Heaters

An alternative option depending on the home and utility setup.

Heat Pump / Hybrid Water Heaters

Designed to improve efficiency with heat pump technology and electric backup.

Thinking about tankless? Here’s when it makes sense

Tankless water heaters heat water on demand instead of storing it in a tank. They can be a great fit for some homes, but they are not the right solution for everyone.

Good fit when

  • Space is limited
  • Your household uses a lot of hot water
  • You want a long-term upgrade option

May not be the best fit when

  • You want the most budget-friendly option
  • Space is not an issue
  • Your hot water delay is caused by plumbing distance rather than the unit itself

Water Heater FAQs

How do I know what size I need?

It depends on how many people live in the home, peak usage (showers/laundry), and your setup. We’ll confirm this during your free quote.

What affects whether I can go power vent or natural draft?

Your venting and layout. We’ll recommend the safest, code-appropriate option after we assess your home.

Do you offer rentals?

Yes — on select models, with easy-to-understand buyout options. Rentals on AO Smith tanked water heaters only.

Is it better to replace before it fails?

If it’s near or past ~10 years, proactive replacement can help avoid water damage risks.
