New AC Installation in San Jose: Sized Right, Installed Right

San Jose’s inland location means summer temperatures regularly hit 95–100°F in neighborhoods like Almaden Valley, Evergreen, and Silver Creek. Homes in these areas need properly sized cooling systems — not the generic “one ton per 500 sq ft” formula that many installers still use. We perform a Manual J load calculation on every installation, accounting for your home’s insulation, window orientation, ceiling height, ductwork condition, and the number of occupants.

Many older San Jose homes in Willow Glen, Rose Garden, and Cambrian Park still run original or second-generation AC systems from the early 2000s using R-22 refrigerant. With R-22 production ended and prices climbing, replacing these systems with a modern R-410A or R-454B unit pays for itself through lower energy bills and eliminated refrigerant costs.

System Types We Install

Central split systems: Outdoor condenser + indoor evaporator coil paired with your existing furnace and ductwork. The standard replacement for most San Jose homes. Brands: Carrier, Lennox, Trane, Rheem, Goodman, Daikin, Bryant, American Standard.

Heat pump systems: One unit handles both heating and cooling. Increasingly popular in San Jose as California pushes electrification. Eligible for federal tax credits and local utility rebates. Learn about heat pump installation.

Ductless mini-splits: Ideal for home additions, converted garages, older homes without ductwork, and rooms the central system can’t reach. Wall-mounted indoor units with individual zone control. Brands: Mitsubishi, Fujitsu, Daikin, LG.

Package units: All-in-one systems that sit outside, common in San Jose homes with limited interior space for a furnace and coil. Heating and cooling in a single cabinet.

Our Installation Process

Step 1: In-home assessment and Manual J load calculation. We measure your home, inspect ductwork, evaluate insulation, and determine the exact BTU capacity needed.

Step 2: Written proposal with equipment options at 2–3 price points (good / better / best). No pressure — we explain the differences and let you choose.

Step 3: Permit pulled with the City of San Jose. We handle all paperwork.

Step 4: Installation by our own technicians (no subcontractors). Typical installation: 1 day for a straight replacement, 2 days if ductwork modifications are needed.

Step 5: City inspection, system commissioning, homeowner walkthrough on thermostat operation and filter maintenance.

FAQ

AC Installation San Jose — Common Questions

A central AC replacement in San Jose typically costs $5,500–$9,000 for the condenser and coil, installed with permit. If you’re replacing both the AC and furnace together, expect $8,000–$14,000. Heat pump systems that handle both heating and cooling run $7,000–$15,000 but may qualify for federal tax credits up to $2,000 and local utility rebates. We provide free in-home estimates with 2–3 options at different price points.
A straightforward replacement (new condenser + coil on existing ductwork) takes 1 day. If we’re adding or modifying ductwork, it’s typically 2 days. A full ductless mini-split installation (single zone) takes half a day. Multi-zone systems take 1–2 days depending on the number of indoor units.
If your furnace is less than 10 years old and running well, replacing just the AC is fine — we’ll match the new condenser to your existing furnace’s coil and blower. If the furnace is 15+ years old, doing both at once saves on labor (one installation instead of two) and ensures the components are matched for maximum efficiency. We’ll give you pricing for both scenarios so you can decide.
