Water Heater Replacement
THE SHORT ANSWER
Most water heaters in Lafayette and Youngsville last 8 to 15 years. If yours is leaking, rusting, making popping noises, or running out of hot water halfway through a shower, replacement is usually cheaper than another repair. Hargrave's replaces tank and tankless units across south Louisiana, most of them same day.

The honest rule of thumb
Repair it, or replace it?
We'll tell you straight before any work starts. Here's the rule we use in Acadiana homes.
REPAIR
Under 8 years old, no tank leak, and the failure is a part: element, thermostat, valve, thermocouple.
REPLACE
Tank is leaking or rusted, unit is 10+ years old, or the repair costs more than half a new install.
UPGRADE
Running out of hot water with a growing family, or you want the attic tank gone. Tankless is worth pricing.

Why Acadiana is hard on water heaters
Attic installs
Common in Lafayette and Youngsville builds, where a failed tank up there becomes a ceiling repair. We install with proper pans, drain lines and shutoffs.
Hard water and sediment
Local mineral content builds up fast, which is what causes the popping noise and kills efficiency years early. An annual flush is included with our Assurance Plan.
Storm-season power cycling
Repeated outages are rough on electric elements and tankless control boards. We check both when we're out.

BOOK ONLINEWater heater questions we get every week in Lafayette and Youngsville
How long does a replacement take?
Two to four hours for a standard tank swap. Attic installs, tankless conversions and code corrections take longer. We'll tell you which before we start.
What size do I need?
Most Acadiana families are right with a 40 or 50 gallon tank. Bigger households, garden tubs, or more than 2.5 bathrooms usually mean two tankless units or two tanks. We size it before we quote it.
Is tankless worth it here?
Often yes: endless hot water, no tank in the attic, lower bills. It costs more up front and it needs descaling with our water. We'll price both and let you choose.
Do you replace on nights and weekends?
Yes, 24/7. A weekend call costs what a weekday call costs. Night and holiday work can price differently, and we tell you the number before we start.
What does it cost?
It depends on size, fuel type, location and what the code requires, which is why we price it in front of you before any work begins. Financing is available.
Do you cover both Lafayette and Youngsville?
Yes. We run trucks out of both shops, 3138 Johnston St in Lafayette and 511 Shore Dr Ste 5 in Youngsville, plus the towns around them: Broussard, Milton, Maurice and the rest of the service area. Same-day replacement applies on most calls from either shop.
