Water Heater Installation & Repair in Aiken, SC
Aiken homes run on a mix of gas and electric tank water heaters, with a growing number of tankless units going into newer builds and remodels. This category covers the full range: replacing a failing tank, installing a new unit in a house that never had one, converting from electric to gas (or the reverse), and repair calls for things like a pilot light that won't stay lit, a leaking tank, a broken heating element, or a unit that just isn't keeping up with a full household anymore. We've identified 26 businesses in the Aiken area that do this work.
What to look for before you hire
Water heater work touches gas lines, electrical circuits, and pressure relief systems, so licensing and permit compliance matter more here than on a lot of plumbing jobs. Ask whether the company pulls a permit for installs (Aiken County requires this for most water heater replacements), whether they carry the right size and type for your household's demand, and whether the quoted price includes haul-away of the old unit, a new expansion tank if code requires one, and updated venting. A same-day or next-day repair response also matters, since a failed water heater rarely happens at a convenient time.

Common questions about water heater installation & repair
- How much does water heater installation cost in Aiken?
- A standard 40-50 gallon electric tank replacement typically runs in the $1,000-$2,200 range including labor, with gas units often a few hundred dollars more due to venting work. Tankless installs cost more upfront, generally $2,500-$4,500, because of the retrofitting often needed for gas lines or electrical service. Get a firm quote before work starts, since permit fees and code-required upgrades (like an expansion tank) can add to the base price.
- How often does a water heater need to be replaced?
- Tank water heaters generally last 8-12 years, a bit less in areas with harder water since sediment builds up faster in the tank. Tankless units can last 15-20 years with regular descaling maintenance. If yours is past the 10-year mark and showing rust-colored water, rumbling noises, or inconsistent temperatures, it's worth getting a professional opinion rather than waiting for a full failure.
- What should I expect during a water heater installation?
- A same-day tank swap usually takes 2-4 hours: draining and disconnecting the old unit, checking that venting and connections meet current code, setting the new tank, and testing for leaks and proper temperature. Gas conversions or tankless installs take longer, often a full day, because of the extra gas line, venting, or electrical work involved.
- How can I tell if a plumber does quality water heater work?
- Look for a company that pulls permits rather than skipping them, explains sizing based on your household's actual usage rather than just swapping in the same size unit, and stands behind the install with a labor warranty separate from the manufacturer's tank warranty. Reviews that specifically mention water heater jobs (not just leak repairs or drain cleaning) are a better signal than general star ratings.
