Whether you are replacing a tired system or adding cooling to a west-side original, Onzone handles AC installation across Dublin, sized right and permitted.
We install across Dublin, including West Dublin, Dublin Ranch, Emerald Glen, and the east side toward Wallis Ranch and Tassajara Hills. Manual J load calculation on every job, permits pulled, and a written line-item proposal before anything is ordered.
Dublin splits between West Dublin, where the first tracts date to 1960 and many homes are on an aging first or second system, and the newer east side. The two call for very different installs, and being 10 minutes away means fast site visits.
Dublin runs the hot dry Tri-Valley summer pattern, so cooling load is real. We size by Manual J so a West Dublin ranch and a new Wallis Ranch build each get the right tonnage, not a copy-paste number.
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, both are included and scheduled by us. You approve the proposal, we handle the city.
Yes. We evaluate the existing ducts and electrical, run the load calc, and quote a full ducted install. Older 1960s homes sometimes need duct or panel work, and that is in the written proposal, not a surprise.
Most residential replacements finish in a day. Adding ductwork or electrical service adds time, and the exact timeline is in the proposal before we start.
If your system is over 12 years old and facing a major repair, replacement usually wins. Not sure yet? Start with AC repair in Dublin and we will tell you honestly.
