Water heaters are the most common call we get. Northeast Florida’s hard water builds scale inside tanks and tankless units, which shortens their life and drives up energy bills. Whether yours needs a quick part, a full replacement or an upgrade to tankless, the owner comes out, and explains your options in plain language.

Water Heaters FAQ

How long does a water heater last in Florida?

A tank water heater typically lasts about 8–12 years here. Hard water and skipped maintenance shorten that. A well-maintained tankless unit can last around 20 years.

Can you replace my water heater the same day?

Usually, yes. We stock common tank sizes, so most replacements are done the same or next day.

Do you work on gas and electric units?

Yes: gas, electric, and tankless units from major brands including Rheem and A.O. Smith.

Do I need a permit to replace a water heater?

In most Florida jurisdictions, yes. We handle the permit when one is required, so the job is done to code.

What brands do you install?

We install trusted brands such as Rheem and A.O. Smith. We’ll recommend the right size and fuel type for your home.
