FAQs

Yes — Union City is part of our regular Bay Area service area. We install and repair tank and heat pump water heaters throughout the city, from neighborhoods near the BART station to homes closer to the hills. Call (408) 733-2000 to schedule a free consultation.

Pricing depends on the type of unit — standard tank or heat pump — and your home’s plumbing and electrical setup. Rather than a rough number over the phone, we visit the property and put together a written, itemized estimate so you know the full cost before anything is scheduled.

It depends on your household’s hot water usage and how much you want to save on energy costs long-term. A heat pump water heater uses significantly less energy and often pays for its higher upfront cost over time, while a standard tank is simpler and cheaper to install if you’re just replacing an existing unit. We’ll walk through the numbers with you during a free consultation.

A musty smell can point to trapped moisture around the unit from a small, ongoing leak, or condensation buildup in a poorly ventilated space. It’s worth checking the area around the tank for dampness and having a technician take a look before mold becomes an issue in the surrounding space.

Often, yes — we treat leaks as priority calls, and same-day service is usually available if you call earlier in the day. Reach us at (408) 733-2000 and we’ll get a technician headed your way.
