AC Installation for Granite Bay's Larger Homes
Granite Bay has some of the region's largest homes. Estate homes here often need a 4-ton or 5-ton unit. Some need multi-zone setups for different wings or bonus rooms. The wrong size creates hot spots no thermostat can fix. Fresh Air does a free load calc on every estimate. We match the unit to your actual home. We are licensed (CSLB #945361), insured, and have done 900-plus installs since 2009.
Milestone Billing for Large Projects
A large new unit is a big cost. Our milestone billing splits payments into stages: materials, install, and final startup. You never pay past what is done.
Zoned AC for Multi-Wing Homes
Large Granite Bay homes often need separate control for each area. We spec and install zoned units — duct dampers or multi-zone mini-splits — based on your layout.

- Free Manual J load calc scaled for large square footage and multiple zones.

AC Installation Costs in Granite Bay
AC install for a large Granite Bay home starts around $8,000. Full swap can reach $15,000 or more for big tonnage with zoning. A 4- or 5-ton unit costs more than a 3-ton. The gear is larger. Wiring needs are higher. Install time grows. Our rough guide is $3,000 to $7,000 per ton installed. We give you a firm price after the free visit.
Granite Bay is in PG&E territory, not SMUD. GoGreen Home financing offers low-rate options for qualifying high-SEER2 gear. Our milestone billing is a plus for large projects. You pay in stages as work finishes, not all at once. Most swaps take about 48 hours. Zoned projects may run two to three days.
