Water Heater Repair & Installation in Chattanooga, TN
Cold showers and lukewarm dishwater are usually the first sign that a water heater is on its way out, but by the time you notice, the unit may already be leaking or failing outright. South East Total Service repairs, replaces, and installs gas, electric, and tankless water heaters for homes and businesses across Chattanooga, and our technicians will tell you honestly whether a repair makes sense or whether replacement is the smarter long-term call.
Signs Your Water Heater Needs Attention
- Inconsistent hot water, or hot water that runs out much faster than it used to
- Rusty or discolored water coming from hot water taps
- Rumbling, popping, or banging noises from the tank
- Water pooling around the base of the unit
- A tank that's approaching or past its typical 10 to 15 year service life
- A pilot light that won't stay lit or repeated tripped breakers on an electric unit

Water Heater Repair
Not every water heater problem calls for replacement. We diagnose and repair thermostats, heating elements, gas valves, igniters, and pressure relief valves on both tank and tankless systems, and we’ll always tell you upfront if a repair is likely to hold or if the unit is close enough to end-of-life that replacement is the better investment.

Water Heater Installation & Replacement
When it’s time for a new unit, we install gas, electric, and tankless water heaters sized correctly for your household’s hot water demand. Tankless systems in particular have become a popular upgrade for Chattanooga homeowners looking to cut standby energy loss and free up space once taken by a large storage tank, and we handle the venting, gas line, and electrical work each installation type requires.

Tankless Water Heater Conversion
Switching from a traditional tank to a tankless system is one of the most requested upgrades we install. Tankless units heat water on demand instead of storing and reheating it continuously, which can lower utility costs and provide a steadier hot water supply for larger households. We evaluate your home’s gas line, venting, and electrical capacity before recommending a conversion, so the finished installation performs the way it’s supposed to from day one.

Frequently Asked Questions
How do I know if my water heater needs to be repaired or replaced?
Age is the biggest factor: most tank water heaters last 10 to 15 years, and a unit near or past that mark is often better replaced than repaired. Active leaks, rust-colored water, and a tank that’s rusting from the outside are also signs replacement is the safer choice. We’ll inspect the unit and give you an honest recommendation either way.
How long does a water heater installation take?
A straightforward tank-to-tank replacement typically takes a few hours. A conversion to tankless, or an installation that requires new venting, gas line, or electrical work, takes longer. We’ll give you a time estimate specific to your home before starting.
Is a tankless water heater worth the upgrade?
Tankless units can lower energy costs by heating water only on demand instead of continuously, and they provide a steadier hot water supply for larger households. Whether it’s worth it depends on your household’s hot water usage and your home’s existing gas, venting, and electrical setup, which we evaluate before recommending a conversion.
What size water heater do I need?
Sizing depends on the number of people in the household, the number of bathrooms, and peak hot water demand. We size each installation to your household’s actual usage rather than defaulting to a one-size-fits-all replacement.
Do you repair tankless water heaters as well as traditional tanks?
Yes. We diagnose and repair both traditional tank water heaters and tankless systems, including issues with heating elements, gas valves, igniters, and control components.
