"On a quiet Sunday morning our 25-year-old water heater started leaking. Jen answered in two rings and gave a detailed, very fair quote immediately. In about 60 minutes, on a Sunday, a tech arrived and had the new water heater installed with a drain pan, expansion tank and earthquake straps in under two hours. HOTCO turned a disastrous weekend surprise into a non-event."
"Jen responded quickly, over Labor Day weekend, answered all my questions about tank vs tankless and recirculation systems, and got me on the schedule first thing Tuesday. Fast, efficient, knowledgeable and friendly. HOTCO deserves their 5-star rating for great service, pricing and stellar staff!"
"Called and got scheduled for the same afternoon! They also indicated it may still be under warranty. The tech came out and troubleshot the issue fast. Knowledgeable, super polite and friendly. Highly recommend."

Shut off the cold water supply valve on top of the tank. For gas units, turn the gas control knob to "Pilot" or "Off". For electric units, switch off the breaker. Then call us. If you smell gas, leave the house and call PG&E or 911 first.
We always look at repair first. Thermocouples, igniters, gas valves, elements, flushing and tankless descaling are often a fast fix. If the tank itself is leaking or the unit is near the end of its life, we give you honest replacement options with upfront pricing.
Yes. We install, repair, flush and descale tankless units from Navien, Rinnai and more, and we handle tank-to-tankless conversions including gas line and venting upgrades.
