Your AC runs nonstop, blows warm air, or will not start during a hot Bay Area evening.
The furnace or heat pump fails after business hours, leaving rooms cold and the thermostat calling without response.
You smell gas near the furnace, meter, or mechanical room and need urgent guidance before any HVAC restart.
A walk-in cooler or freezer is warming up after hours, putting food, product, or inventory at risk.
A real person answers. No phone tree, no “press 9 for emergencies.” Holidays, weekends, 2am. Same line, same answer.
If you smell gas or suspect CO, get out of the building and call 911 or PG&E first. Then call us so we can be moving while you are safe.
If you are on our annual maintenance plan, emergency calls get priority dispatch and a discounted after-hours rate.
Anything safety-related (gas smell, CO concerns, electrical smell, water leak ruining ceilings) is always an emergency. Comfort failures (no heat in winter, no AC in a heat event) are emergencies when there are vulnerable people in the house or when the indoor temperature is heading past safe limits.
After-hours service carries a flat trip premium on top of the standard diagnostic fee. The premium is quoted on the phone before we dispatch so there are no surprises. Maintenance plan customers get a reduced premium.
Leave the building. Do not turn on lights or appliances on the way out. From outside, call 911 first and PG&E’s gas leak line at 800-743-5000. Then call us at (650) 698-7979 so we can be ready to come in once PG&E clears the property.
Yes. Restaurants with down walk-ins, retail with HVAC out during open hours, commercial refrigeration with inventory at stake. We have a separate dispatch path for commercial. Details here.
