View Full Estimate →Every AC installation we do starts with a Manual J load calculation. It is the only accurate way to determine the correct system capacity for a specific home. Insulation level, window area, ceiling height, sun exposure, and duct condition all factor in. A system sized by square footage alone will either underperform or cost too much to run.
For homes with existing ductwork in good condition, central air installation is usually the most cost-effective cooling solution. The licensed HVAC contractor assesses duct condition, sizes the system correctly for the existing distribution, and installs with a mechanical permit and Title 24 inspection. Central AC installation runs $3,500 to $8,000.
A significant share of the pre-1975 housing stock across the service area was built without central ductwork. Ductless mini split installation bypasses the $5,000 to $8,000 duct retrofit entirely. A 3-inch wall penetration, a wall-mounted air handler, and an outdoor unit are all that is needed. Single-zone systems start at $2,500 to $4,500 installed.
Every AC installation in California requires a mechanical permit and a Title 24 Part 6 energy compliance inspection. A system installed without a permit is not covered by manufacturer warranty and may create issues at resale. We handle both as part of the standard installation process.
