No hot water at ANY fixture — sinks, showers, tubs all cold. Here's what to do about hot water problems in Houston — including the local factors that change the advice.
Do this right now
Check the breaker (electric heaters)
A tripped breaker is the #1 'mystery' cause. Flip it fully off, then on. If it trips again immediately, stop — that's an electrical fault for a pro.
Check the pilot light (gas heaters)
If the pilot is out, follow the lighting instructions printed on the heater. If it won't stay lit, the thermocouple is likely bad — a quick pro fix.
Check the thermostat setting
It should read around 120°F. If someone bumped it down — or it's maxed and water is still cold — the thermostat or element may have failed.
Note the heater's age
Find the serial number label: the first digits usually encode the manufacture date. Tank heaters last 8–12 years; past that, replacement usually beats repair.
Call for diagnosis
Call (844) 699-1165. Tell us gas or electric, tank or tankless, the age, and exactly what the water is doing — a pro can often diagnose by phone and arrive with the right parts.

What makes hot water problems different in Houston
- Hard water with high mineral content — which means sediment buildup kills heaters faster here than the national average.
- In Houston, hurricanes, tropical storms, and intense Gulf humidity — garages and attics where heaters often sit see real temperature swings.
- slab-on-grade homes across flat bayou country, many built from the 1960s–90s
- Flat terrain and high water table mean flooding, not basements — storm drainage overwhelms systems fast
Neighborhoods
If you're in The Heights, Montrose, River Oaks, Galleria, Katy, Sugar Land, The Woodlands, Pasadena, Midtown, Energy Corridor, or anywhere across the Houston metro — Houston, Pasadena, Baytown, Sugar Land, The Woodlands — the steps above apply. Call (844) 699-1165 and mention your neighborhood so we match you with a pro who knows the area.
What to tell the pro when you call
- Gas or electric, tank or tankless, and the approximate age
- Exactly what the water does: fully cold, lukewarm, runs out fast, rusty, smelly
- Any error codes on the display (tankless units)
- Whether the breaker trips or the pilot won't stay lit
- Where the heater sits — garage, closet, attic, basement (affects replacement logistics)
