A twelve-hour weekday window means the appointment can happen before work or after work — not "sometime Tuesday between ten and two." Royale Air installs, repairs and services residential heating and air conditioning, cleans air ducts, and holds a current California C-20 license with a bond and workers’ comp on file.

Straight off their own service description, plus the two jobs customers wrote up in detail.
New residential heating and air conditioning systems, listed on their own service description alongside service and repair.
Heating and AC repair on units already in the house. Angela L. wrote about technicians arriving right away on a very hot day.
The last item in their own description, and a real part of the business rather than an upsell — one review describes new ducting run out to a roof vent.
One thermostat in an upstairs hallway cannot run a whole house. Amine C. called Royale Air about exactly that problem in a two-storey home.
Royale Air works out of 1797 Shattuck Avenue, just off Delaware Street. The California Contractors State License Board lists license #1025922 — classification C-20, warm-air heating, ventilating and air-conditioning — issued 19 April 2017 and current and active today, with a $25,000 contractor’s bond and a workers’ compensation policy on file. Those are checkable against the state’s own database in under a minute, which is more than most HVAC websites can say.
“Newly Servicing Contra Costa County as we have Technicians Whom are located here. Residential HVAC Service, Repair Service, Installation Air Duct Cleaning”
That last line is their own, and it matters: the technicians covering Contra Costa live there. A call from the far side of the tunnel is not a ninety-minute drive from Berkeley — it is somebody local.
