When Every Minute Counts
A heating failure at midnight in January or an AC breakdown during an East Bay heat wave is more than an inconvenience — for elderly residents, infants, or people with health conditions, it can be dangerous.
Hi-Tech HVAC’s emergency response team covers the full Bay Area around the clock. When you call, a live dispatcher answers — not a voicemail. We’ll have a licensed technician en route within the hour in most cases, with parts stocked for your system type.

Emergency Support FAQ
True emergencies include: complete heating failure during a cold snap (especially for elderly or infant households), AC failure during a heat advisory, suspected gas leaks or CO alarm triggers, water flooding from a failed condensate line, and electrical burning smells from HVAC equipment.
Our average response time for dispatched emergency calls is 2–4 hours. San Francisco, Oakland, and San Jose typically see faster response. We always provide a text ETA when we dispatch.
Yes. After-hours, weekend, and holiday calls include an additional dispatch fee (from $149–$175), disclosed before we send anyone. You can always decline and wait for regular hours.
If parts need to be ordered, we implement a temporary solution where possible and provide a firm timeline for the follow-up repair. We never leave a home unsafe or without a clear resolution path.
If you smell gas: turn off the system, leave the building, and call PG&E (1-800-743-5000) before calling us. For electrical burning smells, turn off the system at the breaker. For all other issues, we'll advise on safety during your initial call.
