HVAC Installation in California

Central air conditioning installation typically runs $5,000–$12,000, while a ductless mini split ranges from $3,000–$8,000 per unit. The final number depends on home size, system efficiency, and whether new ductwork is needed. We provide an itemized, upfront estimate after a free home assessment — no hidden fees. Call (408) 733-2000 for an exact quote.

Yes on both counts. California offers rebates for energy-efficient HVAC installations — especially heat pumps — and we help you navigate the paperwork to reduce out-of-pocket costs. Ask about current programs when you call (408) 733-2000.

We install Carrier (SEER2 up to 21, up to 10-year compressor warranty), Trane (SEER2 up to 22, industry-leading build quality), and Daikin (SEER2 up to 24, ultra-quiet — a favorite for ductless installations). As an authorized Carrier dealer, we get factory-direct equipment and warranty support.

Six steps: a comprehensive home assessment, load calculation and system sizing, site preparation (electrical, refrigerant lines, duct routes), professional installation to manufacturer specs and California codes, full testing and commissioning, and a walkthrough with training on your new system. Most installations are completed in one day; projects with new ductwork take 2–3 days.

An undersized system runs nonstop and never quite cools the house; an oversized one short-cycles, wears out faster, and dehumidifies poorly. Both waste energy and shorten equipment life. That’s why we use industry-standard load calculations — measuring your home’s square footage, insulation, windows, and orientation — instead of guessing by “tons per square foot.”

Yes — every installation complies with California’s Title 24 energy codes and local safety regulations, including duct sealing and efficiency standards (the state minimum for most new AC installations is 14.3 SEER2).

Same-day assessments are usually available across our Bay Area service territory, and once you approve the quote, most installations are scheduled within days — not weeks. If your old system has failed completely, tell the dispatcher: replacement projects for homes without any cooling or heating get priority scheduling. Call (408) 733-2000 to book your assessment.
