Call us
(650) 540-7205. The emergency line is open 24/7, and we speak English and Spanish.
Call rather than book online when something is failing right now: no heat on a cold night, no cooling in a heat wave, a burning smell, a breaker that trips when the system starts, or water leaking from an indoor unit. Same-day service is available for urgent repairs. See also emergency HVAC.
If you smell gas, do not use light switches or the phone inside the house. Leave first, then call your gas utility or 911 from outside. If a carbon monoxide alarm sounds, get everyone outside and call 911.
Book online

Mention the symptom and the type of equipment in the request so the technician arrives ready for it.
