Hot Water That
Never Runs Out

Whether your tank water heater is on its last legs or you're ready to upgrade to tankless, RO handles the full job — removal, installation, gas or electric hookup, and code-compliant venting. We install Bradford White, Rheem, Rinnai, and Navien units with honest sizing recommendations and no upselling.

Everything You Need to Know

Water Heater Services
Guide

01

Tank Water Heaters

Traditional tank heaters store 40–80 gallons of pre-heated water. They're reliable and they're the simplest swap on the list — same footprint, same water and fuel connections, and in most cases no venting or electrical changes at all. Standard tank efficiency is 0.60–0.65 EF (energy factor). Lifespan is 8–12 years with proper maintenance. The main drawback: when the tank empties during heavy use (multiple showers, laundry, dishwasher), you wait 30–60 minutes for recovery.

02

Tankless Water Heaters

Tankless units heat water on demand — no tank, no standby heat loss, no running out. Efficiency ratings of 0.90–0.98 EF mean 24–34% energy savings over standard tanks. They last 20+ years with proper maintenance. Rinnai, Navien, and Rheem are the brands we install. The scope is driven by what surrounds the unit, not the unit itself: gas tankless needs a 3/4" gas line minimum, and if your existing line was sized for a tank it usually needs upsizing back toward the meter. It also needs its own venting — concentric or dual-pipe, cut through a wall or roof — because the old tank's flue almost never carries over. Where the unit lands and how far it sits from the meter sets the rest.

03

Heat Pump Water Heaters

The efficiency leader. Heat pump (hybrid) water heaters use ambient air to heat water — 2–3x more efficient than standard electric tanks. Energy Factor ratings of 3.0–4.0 mean a dramatically smaller electric bill every month, and the units qualify for federal energy tax credits. The trade-offs are physical, and they're what set the install: the unit needs 700+ cubic feet of surrounding air space, a condensate drain it didn't need before, and it blows cold exhaust air — so a tight interior closet usually won't work while a garage or basement will. Relocating the heater to make that happen means extending water lines and running a new circuit. They work best in warm climates, and the Southeast gives them about as good a run as they get.

04

Why It Matters Here

Water heating is the second-largest energy expense in most homes (14–18% of your utility bill). The long warm season across the Carolinas and north Georgia makes heat pump water heaters exceptionally efficient — the ambient warmth they pull out of the surrounding air is free and abundant here ten months of the year. Between energy savings and available tax credits, upgrading from a standard tank to a heat pump unit often pays for itself in 3–5 years.

Warning
Signs

Your water heater is more than 10 years old

Average tank lifespan is 8–12 years. After 10, failure risk increases significantly. Check the manufacture date on the rating plate — the first two digits of the serial number are often the year.

Rust-colored hot water

Rusty hot water (but clear cold water) means the anode rod has failed and the tank itself is corroding. Once the tank starts rusting, replacement is the only permanent fix.

Rumbling, popping, or banging sounds

Sediment buildup on the tank bottom hardens and traps water beneath it. The popping sound is trapped water boiling through the sediment layer. This reduces efficiency and accelerates tank failure.

Water pooling around the base

Any water on the floor near the heater means either a leaking fitting (fixable) or a cracked tank (replacement needed). Check the T&P relief valve, supply connections, and the tank bottom.

Hot water doesn't last as long as it used to

Sediment displaces water volume inside the tank. A 50-gallon tank with heavy sediment may only hold 30 gallons of usable hot water. Flushing helps if caught early; replacement if the buildup is severe.

Your energy bills have increased without explanation

An inefficient water heater working harder to maintain temperature draws more energy. Sediment insulates the burner from the water, forcing longer run cycles.

How We Do It

Our
Process

01

Assessment & Sizing

We evaluate your current setup, measure hot water demand (household size, fixtures, simultaneous usage), and recommend the right type and size. Oversizing wastes money; undersizing leaves you cold.

02

Unit Selection

We walk you through options — tank, tankless, or heat pump — with honest comparisons of upfront cost, operating cost, and payback period. We carry Bradford White, Rheem, Rinnai, and Navien.

03

Removal & Prep

We disconnect and remove the old unit (including disposal), verify gas/electric supply sizing, check venting requirements, and prepare the installation area. If gas line upgrades are needed, we handle that too.

04

Installation

New unit is set, connected to supply and return lines, gas/electric hooked up, and venting installed or modified. Tankless units require specific venting (concentric or dual-pipe) and may need electrical for controls.

05

Testing & Walkthrough

We fire up the unit, verify proper operation, check for leaks, measure output temperature, and walk you through the controls — temperature setting, vacation mode, and maintenance schedule.

Scope & Longevity

What Drives the Number

What Moves It
Lifespan
Tank Water Heater (40–50 gal)
Straight swap unless the pan, expansion tank, or shutoff has to change
8–12 years
Tank Water Heater (75–80 gal)
Bigger footprint — doorways, stairs, and closet clearance set the labor
8–12 years
Tankless Water Heater (installed)
Gas line sizing and new venting, not the unit, set the scope
20+ years
Heat Pump Water Heater (installed)
Needs air volume, a condensate drain, and often a new location
12–15 years
Anode Rod Replacement
Headroom above the tank; a low ceiling means a segmented rod
3–5 years
