Water Heater Replacement – Charleston, SC
A failing water heater can disrupt your entire day—no hot showers, no clean dishes, and no comfort. If your system is no longer performing like it used to, it may be time for an upgrade. At Simply Plumbing and Gas, we provide professional water heater replacement services across Charleston, SC. Whether your unit is leaking, inefficient, or completely out of commission, our licensed plumbers will help you find and install the right solution for your home or business.
When to Replace Your Water Heater
Most water heaters are built to last between 8 to 12 years. As they age, their efficiency declines, and the risk of leaks and other issues increases. If you’ve been dealing with inconsistent hot water or frequent repairs, it may be more cost-effective to replace your unit.
Common signs it’s time for a replacement:
- Little to no hot water
- Water that is rusty or discolored
- Strange noises coming from the tank
- Leaking or pooling water around the base
- An increase in utility bills
- A unit that is 10+ years old and failing repeatedly
If any of these symptoms sound familiar, our team can inspect your unit and walk you through the best replacement options available.
