Tank or tankless, gas or electric — we diagnose, repair, and install water heaters across San Antonio with same-day availability and honest quotes.
Not sure if you have a problem? Look for these common indicators.
Complete loss of hot water usually means a failed heating element, dead pilot light, or a thermostat problem.
Lukewarm water or running out quickly often points to sediment buildup, a failing element, or a unit that is undersized for your household.
Brown or rusty water from hot taps means the anode rod is spent and the tank is corroding internally. Replacement is usually needed soon.
Sediment at the bottom of the tank hardens and traps water underneath. When it heats, steam bubbles pop through the sediment layer — the banging sound you hear.
Water pooling around the bottom of the tank typically means internal corrosion has created a crack. This cannot be repaired — the unit needs replacement before it floods.
An inefficient heater works harder and runs longer. If your gas or electric bill spiked without other changes, the water heater is a likely culprit.
We test thermostats, elements, gas valves, anode rods, and venting before recommending any work.
Honest recommendation: if repair costs more than 50% of a new unit, we tell you.
All installations include required City of San Antonio permits and pass inspection.
We haul away your old water heater at no extra charge.
A water heater works harder in San Antonio than most places. Our notoriously hard water (15–25 grains per gallon) accelerates sediment buildup inside the tank, reducing efficiency and shortening the unit's life by 2–4 years. If your heater is 8+ years old and you've never flushed it, you're likely heating through inches of mineral scale.
TruFlo repairs all major brands — Rheem, A.O. Smith, Bradford White, Rinnai, Navien, and more. When repair isn't cost-effective, we'll give you honest options for replacement, including energy-efficient tankless systems that can cut your water heating bill by 30–40%.
We handle everything: gas and electric tank heaters, tankless on-demand systems, point-of-use units, and recirculation pumps. All installations include permits, code-compliant venting, and a written warranty.
