Tankless Installation
Tankless water heaters provide hot water on demand and last significantly longer than tank units. We install gas and electric tankless systems and handle any gas line or electrical upgrades needed.

Heat Pump Water Heaters
Heat pump water heaters are 2–3x more efficient than standard electric units and can qualify for federal tax credits. We install and service these systems throughout the north Atlanta metro.
Common Water Heater Problems We Fix
Most water heater service calls fall into a handful of categories. No hot water at all usually points to a failed heating element, a tripped breaker on electric units, or a failed thermocouple or gas valve on gas units — most of these are same-day repairs. A leaking tank is a more urgent situation, especially if water is pooling around the base, which typically means the tank itself has failed and replacement is necessary. Discolored or rust-colored water often indicates corrosion inside the tank or a failing anode rod. Inconsistent hot water — running out faster than usual or getting water that’s too hot — is usually a thermostat or sediment buildup issue. We flush and descale tanks as part of our service process.
Tank vs. Tankless: What’s Right for Your Home?
Traditional tank water heaters are less expensive upfront and straightforward to replace. A 40–50 gallon gas unit is typically sufficient for a family of four. The downside is standby heat loss — the unit constantly reheats water in the tank even when you’re not using it, which adds to your energy bill. Tank units generally last 8–12 years.
Tankless water heaters heat water on demand, which eliminates standby loss entirely. They’re more expensive upfront but last 15–20 years and cost significantly less to operate. The main consideration is flow rate — a gas tankless unit handles simultaneous demand much better than an electric one, which matters in larger households. If you’re consistently running out of hot water or replacing an aging tank unit, a tankless upgrade is worth considering. We’ll walk you through the numbers before you decide.
Frequently Asked Questions
How long does water heater replacement take?
Most standard tank replacements take 2–3 hours including removal of the old unit. Tankless installations can take longer depending on whether gas line or venting modifications are needed. We’ll give you a time estimate when we quote the job.
My water heater is 8 years old. Should I repair or replace it?
At 8 years, a tank water heater is approaching the end of its typical lifespan. If the repair is minor — a thermostat or element — it may be worth fixing. If the tank is leaking or the repair cost is significant, replacement is usually the smarter investment. We’ll give you both options and let you decide.
