When you need it
- Rusty or discolored hot water, or popping and rumbling sounds from the tank
- Water pooling around the base of the heater
- Unit is over 10 years old or you're running out of hot water faster than before
What's required
We assess the existing setup, confirm gas line size, electrical capacity, and venting, and pull the permit San Antonio typically requires. Tank replacements are usually same-day; tankless conversions can take 1-2 days.
