From single-family homes to Rossmoor condos, Onzone handles AC installation across Walnut Creek, sized to the space and permitted.
We install across Walnut Creek, including downtown, Northgate, Saranap, Walnut Heights, and Rossmoor. Manual J load calculation on every job, permits pulled, and a written line-item proposal before anything is ordered.
Walnut Creek mixes mid-century single-family homes with condo communities like Rossmoor, a 55 plus community of about 10,000 residents. Condo installs mean tight mechanical spaces and HOA coordination, and we are set up for both.
Walnut Creek summers sit in the 80s under long stretches of sun. We size by Manual J, which matters especially in condos where an oversized unit is loud, inefficient, and hard to fit.
You get a line-item proposal covering equipment, labor, permit, and disposal before anything is ordered. We pull the permit and handle the city inspection, so the price you approve is the price you pay.
Yes, permit and inspection are included and coordinated by us.
Yes, Rossmoor is a regular stop. We work within the tight mechanical closets and the community access rules, and size the unit to the space.
