Same-day repair, with the parts already on the truck.
It's 4pm on the third day of a heat wave and the condenser stopped. The call that ends with us walking back to the parts house at 6pm doesn't happen here.

What we do
Three jobs, done by the same crew.
Annual service that catches the failures before July.
A failed condenser fan motor in summer costs four times what catching it in spring does. We check the components that fail predictably — capacitors, contactors, blower motors — and replace them before they take the system with them on the worst day of the year.
Carrier-authorized installs, sized to the actual house.
When the repair bill keeps creeping up and the system is past its warranty, we'll tell you. Manual J load calculation on every install, equipment sized to the house you actually live in, and one fixed quote with parts, labor, and warranty terms broken out separately.
Method
What gets fixed today gets fixed once.
Most HVAC calls go four days. Technician arrives, names a part, doesn't have the part, schedules a return visit, sends a written quote tomorrow, parts arrive Thursday, return visit Friday. By Friday you've called three other companies.
Our trucks roll out loaded. Capacitors, contactors, blower motors, refrigerant, the common board failures — the parts that account for most of what fails in Sonoma County residential systems. We diagnose on site, we explain what we found, we quote off the diagnosis, we install the part the same visit. If the failure mode isn't on the truck, we tell you immediately what we need and how fast it gets here.
Same-day dispatch is a scheduling promise. Same-day repair is an inventory and diagnostic discipline.

Credentials
The license, the certifications, and what they actually mean.
Northbay Heating & Air has serviced Sonoma County since 2012. We hold a California C-20 contractor license, employ NATE-certified technicians, and carry EPA Section 608 universal certification for every refrigerant we touch. Carrier named us a Factory Authorized Dealer, which means warranty work, factory parts, and equipment sized correctly the first time.
Diamond Certified — the rating is based on a statistically significant sample of our actual customers, not an internal average. If you'd like to see the report, it's public.
What customers say
“Our condenser fan motor failed the second day of a heat wave. Northbay had a tech at the house in eighty minutes with the part on the truck — the same failure mode they'd warned us about during last year's maintenance visit. Charged us the same flat repair rate as a non-emergency call.”
— Robert and Carol Hammond, Petaluma

Most repairs close on the first visit.
If the part is on the truck, it goes in. If we need to source something, you'll know immediately what's needed and the realistic timeline.
