AC Installation Cost in the Bay Area
Central AC installation (AC-only) in the Bay Area typically ranges from $7,500–$15,000, depending on equipment tier, home size, and duct condition. If you're replacing both a furnace and AC, see our Furnace + AC page for combined pricing.
Inland Bay Area cities — Walnut Creek, Concord, Livermore, Pleasanton, San Jose, Brentwood, Antioch, and the East Bay foothills — regularly hit 100°F+ during summer. A properly sized, high-efficiency AC system pays for itself in comfort and energy savings within a few years.
All our installations include permits, a free UV Air Scrubber ($800 value), a 10-year manufacturer warranty registration, and a 5-year labor warranty.

Factors That Affect AC Installation Cost
- Home Size & Tonnage: Most Bay Area homes need 2–4 tons. Undersizing causes constant cycling; oversizing causes humidity problems and higher bills.
- SEER2 Efficiency: A 14.5 SEER2 unit is code-minimum and affordable; a 22 SEER2 variable-speed unit can cut cooling bills by 30–40%.
- Duct Condition: Leaky or undersized ducts reduce efficiency and airflow. Duct sealing adds $500–$1,500; duct replacement is more.
- Lineset: If no existing copper refrigerant lines, or existing ones are damaged, replacement adds $600–$1,200.
- Electrical Panel: If panel upgrade needed (200A), adds $3,000+.
- Permits: $975–$1,675 depending on city. Always included in your final quote.

AC Installation FAQs
How much does AC installation cost in the Bay Area?
Central AC installation in the Bay Area typically costs $7,500–$15,000 installed, depending on the brand, SEER2 efficiency rating, and your home's ductwork condition. A basic 14.5 SEER2 system for a 1,500 sq ft home starts around $7,500; a premium 20+ SEER2 variable-speed unit for a larger home can reach $14,000–$15,000. Permits ($975–$1,675) are always included in our final quote.
Do I need AC in the Bay Area?
Increasingly, yes. While coastal areas like San Francisco stay mild, inland Bay Area cities — Walnut Creek, Concord, Livermore, Pleasanton, San Jose, and the East Bay foothills — regularly hit 95–110°F during summer heat waves. Climate change has made these events more frequent and severe. Central AC is now a standard upgrade for most Bay Area homeowners east of the coast.
What is SEER2 and why does it matter?
SEER2 (Seasonal Energy Efficiency Ratio 2) measures how efficiently an AC converts electricity into cooling. Higher SEER2 = lower monthly electric bills. In the Bay Area, where cooling seasons are moderate, a 16–18 SEER2 unit often offers the best payback. Variable-speed 20+ SEER2 systems cost more upfront but can cut cooling costs by 30–40% annually.
How long does AC installation take?
A standard AC installation — replacing an existing system with existing ductwork — takes 4–8 hours in a single day. New AC installations that require running a lineset, adding a disconnect, or modifying ductwork may take 1–2 days. We pull all permits and coordinate city inspections.
Is my existing ductwork compatible with a new AC?
Usually yes, if the ducts are in reasonable condition. We do a duct blaster test during our in-home assessment to check for leaks and sizing. If ducts need sealing or resizing, that's quoted separately — typically $500–$2,000 for sealing; more for major modifications.
What brands of AC do you install?
We install Carrier (Comfort, Performance, and Infinity lines), American Standard (Silver, Gold, and Platinum lines), Lennox, Trane, Rheem, Daikin, and Bosch air conditioners. We'll recommend the best brand and model for your home size, usage patterns, and budget during your free in-home consultation.
What Our Customers Say
We got a Lennox furnace and AC combo for our 2,400 sq ft home. The online estimator gave us an accurate quote and there were zero surprises on install day. They pulled permits, handled everything with the city, and even helped us understand the HEEHRA rebate process.

Furnace & AC InstallationOur old AC died during a 105° heat wave. They had a new American Standard 16 SEER2 system installed the next day. Fast response, fair pricing, and the new unit cools our 1,800 sq ft home evenly. Highly recommend for AC installation in the East Bay.

Furnace & AC InstallationThird time using them — first for our AC, then our rental property, and now a Carrier furnace for my parents' home in Fremont. Consistent quality every time. They handle permits and inspections so we don't have to worry about anything.

Furnace InstallationReplaced our 18-year-old Lennox AC with a new Carrier 18 SEER2 unit just before summer. The installation crew was in and out in under 5 hours. Our home cools down in half the time it used to, and the new system is whisper quiet. The online estimate was spot-on.
