Water heater repair and installation in Duval

Tank or tankless, gas or electric — we repair what's worth repairing and we replace what isn't, with a free written estimate before either decision gets made.

Anything to do with the appliance that makes your hot water. Tank, tankless, gas, electric — repair what’s worth repairing, replace what isn’t, with a free written estimate before either decision. A water heater’s average lifespan in Florida is 8 to 12 years for tank-style, longer for tankless. We don’t push the bigger job. We don’t push the smaller job either. We tell you what we’d do if it were our house.

Typical symptoms

  • No hot water at all (thermocouple, gas valve, element, breaker)
  • Not enough hot water (dip tube, sediment, undersized tank)
  • Brown or rust-colored hot water (anode rod gone, corrosion starting)
  • Water around the base of the tank (fitting failure, or the tank itself)
  • Banging or popping sounds (sediment baked onto the bottom element)
  • Hot water that smells like rotten eggs (bacterial reaction with anode)

Scope of work

  • Tank-style heater repair (40, 50, 75-gallon, gas or electric)
  • Tankless heater repair and descaling
  • Same-day tank replacement (most standard sizes)
  • Tankless retrofit installs (gas-line or electrical-panel upgrades handled)
  • Power-vent and direct-vent installs
  • Anode rod replacement (the maintenance most homeowners skip)
  • Manufacturer warranty registration on a new install
FAQ

Frequently asked

Six common questions for water heater repair & installation.

How long does a water heater last?

In Duval, tank-style water heaters average 8 to 12 years — sometimes longer with regular flushing, sometimes shorter on a well or with hard water. Tankless heaters last 15 to 20 years if you keep up with annual descaling. The single biggest factor is whether the anode rod has been replaced once or twice over the tank's life — most homeowners don't know that's a thing, and it's why most tanks die at 10 instead of 15.

How do I know if I should repair or replace it?

Three signals push toward replace: the tank is leaking from the body (not a fitting), the tank is over 10 years old, or the repair cost is more than half what a new tank would cost. Three signals push toward repair: the tank is under 8 years old, the symptom is a part (thermocouple, element, thermostat, gas valve), and the tank itself shows no rust or sweating. We'll quote both options when it's borderline and let you pick.

Tankless or tank — which one should I get?

Tankless if you're staying in the house long enough to earn back the higher install cost (usually 7+ years), if you have the gas-line capacity or electrical panel headroom, and if you want the floor space or the longer service life. Tank if you want the lower up-front cost, faster install (usually same day), and easier future repair. For a household of two-to-four people in a typical Duval home, a 50-gallon tank does the job and costs roughly half what a tankless retrofit costs.

What brands do you install?

We install most major brands — Rheem, A.O. Smith, Bradford White, State, Navien (tankless), Rinnai (tankless). We're not a single-brand exclusive dealer. What we recommend depends on your situation — household size, gas vs. electric, install location, budget — not on which brand pays us the most.

Do I need a permit to replace my water heater?

In Duval County, yes — a permit is required for any water heater installation, repair-only is usually not. We pull the permit and coordinate the inspection so you don't have to. Permit cost is on the written estimate, not added at the end.

How long does a typical install take?

A standard tank replacement (same fuel type, same location, no code upgrades needed) is usually done in 2 to 4 hours. A tankless retrofit takes longer — usually a full day, sometimes two if a gas-line upsize or a venting reroute is needed. We tell you the realistic timeline on the estimate, not the marketing version.
