What to expect after you reach out

Phone calls. Every call is answered at any hour, 7 days a week, by our AI phone assistant. A team member calls back to confirm the appointment, within 10 minutes during business hours (7AM – 7PM · 7 days). After hours, we call back as soon as we can, or first thing next morning. No overtime charges.

Online form and HCP booking reviewed within one hour during business hours, next-morning for overnight submissions. You receive an SMS confirmation as soon as we have your address and equipment details.

Genuine emergencies (cooling failure during a heat wave, heating failure during a cold snap, water leak from a unit), call directly, do not submit the form. We prioritize cooling emergencies in summer and heating emergencies in winter.

Smell gas? Leave the building and surrounding area immediately. From a safe location, call 911 and your gas utility. Do not use electrical switches, phones, or anything that could create a spark while near the suspected leak. Contact us for equipment service only after emergency responders or the gas utility confirm it is safe.

Before you call

What information should I have ready?
Your address, the equipment brand (check the label on your furnace or AC), approximate age of the system, and what is happening. Photos help if you can take them, you can text them to (925) 999-4095 after we connect.

Can you give me a rough price over the phone?
For common repairs, yes: ballpark ranges. For installations, we need to see the home. Bay Area homes vary too much for reliable phone quotes. Our $99 diagnostic is credited toward the repair.

Do you offer financing?
Financing available on approved credit. We go over the options at the installation assessment.

What happens after I submit the form?
You get an SMS confirmation immediately. Andrew reviews your submission within one hour during business hours. You will hear from us by phone or text with an estimated visit time and any clarifying questions.
