Signs It’s Time
Match the symptom to the usual next step. We’ll confirm on site before any work begins.
No hot water
Often a repair: a pilot, igniter, heating element, thermostat or tripped breaker. Call us first.
Hot water runs out fast
Could be sediment or a failing element, or a tank that is now too small for the household.
Water around the tank
A leaking fitting or valve can usually be fixed. A leak from the tank itself usually means replacement.
Rusty or smelly water
Often a worn anode rod, which can be replaced. Rust coming from the tank points to replacement.
Popping or rumbling
Usually sediment. Flushing can help, but heavy buildup in an older tank may mean it is near the end.
10+ years old
Tank water heaters typically last 8–12 years. A planned replacement beats an emergency one.

Sizing & Replacement AdviceHelp choosing the right type and size before you buy.Repair or Replacement
We diagnose first, then tell you honestly which makes more sense for your unit.
Repair
When a repair usually makes sense
Most problems with a younger unit come down to one part. We repair:
Replacement
When replacement is the better choice
Planning a replacement before the old unit fails avoids a flooded floor and a rushed decision.
Installation
Size it
We look at household size, peak hot-water demand, fuel type, venting and your electrical panel.
Choose and price
We explain the tank, tankless and heat pump options that fit and give you the price before any work begins.
Install
We remove the old unit and connect the new one to water, gas or electric, and venting where needed.
Test and walk through
We check for leaks, test the relief valve and set the temperature before we leave.
Standard tank replacements can often be done the same or next day when technicians are available; tankless and heat pump installs may take 1–2 days. We serve homes in Calhoun, Adairsville, Dalton, Rome, Cartersville and across Northwest Georgia.
Choosing a New One
Each type fits a different home and budget. Here is how they compare in general terms.
| Compare | Tank | Tankless | Heat pump |
|---|---|---|---|
| Upfront cost | Lowest | Higher, plus any gas, venting or electrical upgrades | Higher |
| Typical lifespan | 8–12 years | 15–20+ years | Varies by model; ask about the one you’re considering |
| Operating cost | Highest for electric tanks | Lower: heats water only when you use it | Lower than a standard electric tank |
| Hot water supply | Limited to the tank size | Continuous, limited by flow rate | Limited to the tank size; slower recovery at high demand |
| Space needs | Standard closet or garage | Compact, wall-mounted | Needs room and surrounding air; garages and basements often work well |
| Best fit | Simple swaps and tighter budgets | Homes with gas and high, steady demand | Electric homes looking to cut water-heating costs |
How we size it: household size, peak hot-water demand, fuel type, venting and your electrical panel. We explain the trade-offs before you choose.
Our Approach
When your water heater fails, you need fast, honest service from a company that stands behind its work. Anderson Heating, Air & Insulation has been keeping homes in Calhoun and Northwest Georgia supplied with hot water since 1978.
As a BPI-certified home-energy contractor, we treat your water heater as part of your home's comfort and energy system, not a stand-alone appliance. That means sizing the unit to your household and recommending a heat pump water heater only when it fits the home.
"We treat every home like it's our own, because that's how we want our neighbors to feel." The Anderson Difference
Rebates
Water heater incentives have changed. The federal energy-efficiency tax credit ended for equipment installed after December 31, 2025, and Georgia stopped accepting new HEAR applications on August 14, 2026. An efficient water heater may still count toward the savings in a whole-home project under Georgia's HER program.
We'll tell you what currently applies before you decide. See our Georgia energy rebates guide for the current program status.

FAQ
Traditional tank water heaters typically last 8–12 years. Tankless units often last 15–20 years or more. Water quality and maintenance make a big difference, and we help you choose the right system for your home and usage.
Repair usually makes sense for a younger unit with a failed part, such as a thermostat, element, igniter or valve. Replacement usually makes sense when the tank itself is leaking, the unit is around 10 years old or more, or repairs keep adding up. You get the price before any work begins.
It depends on how many people live in the home, how much hot water you use at the same time and the fuel type. Tank units are sized by capacity and recovery; tankless units by flow rate. We size the unit to your household rather than just matching the old one.
