Livermore runs the hottest summers in the Tri-Valley and real winters too, so a whole-system HVAC installation has to handle both. Onzone sizes and installs the full system here.
We install across Livermore, including downtown, North Livermore, Springtown, and the South Livermore wine country: furnace, AC, heat pump, and mini-split. Manual J sizing on every job, permits pulled, and a written proposal before anything is ordered.
Livermore tripled between 1970 and 2000, so a huge share of the housing carries 70s-through-90s furnaces and AC now due together. We do whole-system replacements and heat pump conversions across that older stock and the newer south side.
A heat pump handles Livermore heat and cool winters on one electric system and qualifies for BayREN, PG and E, and BAAQMD rebates. We size it to real peak load, map the rebates, and compare it to a gas-and-AC swap.
You get a line-item proposal covering equipment, labor, permit, and disposal before anything is ordered. We pull the permit, handle the city inspection, and map any rebate you qualify for, so the price you approve is the price you pay.
Often yes, because Livermore works both hard. Matching them as a system gets sizing right for the hottest afternoons and the cool winters. We quote both paths.
Yes, sized correctly. We run a Manual J for the real peak load rather than a mild-day average. See heat pump installation.
Yes, permit, inspection, and the rebate paperwork are all handled by us.
