Our Water Heater Replacement Process
Diagnosis
We assess your current water heater — age, condition, fuel type, and capacity — to determine whether repair or replacement is the right call.
Recommendation & Quote
We recommend the right unit for your household size and budget, and provide a detailed quote including all parts, labor, and disposal.
Same-Day or Scheduled Install
We stock common water heater sizes and can often complete same-day replacement for urgent no-hot-water situations.
Removal & Disposal
We disconnect and haul away your old unit — no disposal fees or trips to the dump for you.
Installation & Code Compliance
We install the new unit, connect gas or electrical, install the expansion tank, and verify all connections meet current plumbing code.
Testing & Walkthrough
We test the unit for proper temperature, pressure relief, and leak-free connections, then walk you through maintenance and warranty.
Water Heater Related Services
A leaking water heater can cause significant water damage if not addressed quickly. If you notice water pooling around your unit, our leak detection team can determine the source. San Antonio's hard water accelerates tank corrosion — installing a water softener can extend your water heater's lifespan. Gas water heaters require proper gas line connections, and electric models may need a dedicated circuit or panel upgrade — both of which we handle in-house.
