The size should be based on load, duct condition, insulation, windows, sun exposure, and local climate. Square footage alone is not enough, especially in Bay Area homes where fog, hillside exposure, and inland heat can change the room-by-room load.
New AC installation costs range from $5,000-$15,000+ depending on system size (tons), efficiency rating (SEER2), brand, and installation complexity. Bay Area installations may be higher due to permitting requirements and labor costs.
AC sizing depends on square footage, ceiling height, insulation, window orientation, and local climate. A general rule is 1 ton per 500-600 sq ft, but Bay Area microclimates vary significantly. We perform Manual J load calculations for accurate sizing.
