FAQs

Cost depends on the system type — central AC, ductless mini split, or a window/wall unit — plus your home’s square footage and current ductwork. California’s Title 24 energy code also affects which equipment qualifies for installation. We provide a clear, itemized quote after a free on-site assessment anywhere in the Bay Area. Call (408) 733-2000 to get your exact price.

Both work well across California’s varied climate zones. Central AC delivers even cooling through existing ductwork and suits larger homes, while ductless mini splits reach higher SEER2 ratings, skip duct losses entirely, and let you cool individual rooms independently — a common choice for older Bay Area homes without ducting. We size both options for your space and budget during a free consultation.

Most central AC replacements take 4–8 hours, and a ductless mini split installation runs 3–6 hours per zone, so cooling is typically restored the same day. Projects that include new air duct installation or a full system upgrade may take 2–3 days. We confirm your exact timeline during the on-site visit and schedule the work to minimize disruption.

Yes. California requires a permit for new AC unit installation and most system replacements, along with compliance with Title 24 energy standards. As a licensed contractor (License #901246), we handle permit filing, inspections, and code compliance for you, so your installation is fully documented from start to finish.

Sizing depends on square footage, ceiling height, insulation, window exposure, and local climate — a rough per-square-foot estimate is never reliable. An undersized unit runs constantly without properly cooling your home, while an oversized one cycles too often and wastes energy. We perform a full load calculation before recommending equipment, whether you’re in a coastal or inland part of California.
