General HVAC Cost Questions
How much does HVAC installation cost in the Bay Area?
HVAC installation in the Bay Area typically costs $8,500–$22,000 depending on the system type, home size, and whether ductwork is needed. A basic central AC system for a 1,500 sq ft home starts around $8,500; a premium variable-speed heat pump for a 3,000 sq ft home can reach $18,000–$22,000. Our online estimator gives you a detailed, itemized quote in under 2 minutes with no personal information required.
What's included in your HVAC installation price?
Our all-inclusive prices cover equipment (the system you select), labor (our EPA-certified installation crew), all city and county permits, refrigerant, thermostat, electrical disconnect, lineset, and startup commissioning. There are no hidden fees — the price you see in our estimator is the price you pay.
Why is HVAC installation more expensive in the Bay Area than the national average?
Bay Area HVAC costs are 20–35% higher than the national average due to higher labor rates, Title 24 California energy code compliance requirements, higher permit fees (especially in San Francisco and Santa Clara County cities), and the additional cost of properly sizing systems for the Bay Area's microclimates. The good news: Bay Area utility rebates through PCE, SVCE, MCE, and EBCE/Ava — plus our $3,000 seasonal discount — can meaningfully reduce your net cost.
How long does HVAC installation take?
Most standard HVAC installations take 1–2 days. A simple furnace swap or AC replacement with existing ductwork is usually completed in a single day. A full heat pump installation (replacing both furnace and AC) typically takes 1.5–2 days. New ductwork, panel upgrades, or complex multi-zone ductless systems can take 2–3 days. We pull permits before scheduling and schedule the city inspection for the day of or the day after installation.
Do you pull permits for HVAC installation?
Yes — we pull all required city and county permits as part of every installation. HVAC permits are legally required in all Bay Area cities and are included in our quoted price. We handle the permit application, city inspection scheduling, and final sign-off. You receive a copy of the finaled permit for your records, which is important for home resale and insurance.
What brands of HVAC equipment do you install?
We install Carrier, American Standard, Lennox, Daikin, Rheem, Bosch, and Mitsubishi equipment. As a Carrier Authorized Dealer and American Standard Authorized Dealer, we offer factory-backed warranties on those brands. Our estimator shows pricing for multiple tiers so you can compare efficiency levels and brands side by side.
How do I know what size HVAC system I need?
System size (measured in tons for AC/heat pumps, BTU for furnaces) is determined by a Manual J load calculation that accounts for your home's square footage, ceiling height, insulation, window area, and local climate data. A 1,500 sq ft Bay Area home typically needs a 2–2.5 ton system; a 2,500 sq ft home usually needs 3–3.5 tons. Our estimator uses your square footage as a starting point; our technician performs a full Manual J during the on-site assessment.
Heat Pump Installation FAQs
How much does heat pump installation cost in the Bay Area?
Heat pump installation in the Bay Area costs $9,000–$18,000 installed. A standard 14.5 SEER2 system for a 1,500 sq ft home starts around $9,500; a premium 20+ SEER2 variable-speed system for a larger home runs $14,000–$18,000. After utility rebates (PCE, SVCE, MCE, or EBCE/Ava depending on your county) and our $3,000 seasonal discount, your net cost can be $3,000–$5,000 less than the sticker price.
Is a heat pump worth it in the Bay Area?
Yes — the Bay Area's mild climate is ideal for heat pumps. They provide both heating and cooling from a single system and operate at 200–300% efficiency (vs. 90–98% for gas furnaces). Most Bay Area heat pump owners see 25–50% reductions in combined heating and cooling costs. Combined with utility rebates through your local clean energy provider and our $3,000 seasonal discount, the payback period is typically 4–6 years.
Can a heat pump handle Bay Area winters?
Yes. Modern cold-climate heat pumps operate efficiently down to 5°F and remain effective in the 40–55°F range common in Bay Area winters. For inland areas that occasionally see frost (Livermore, Walnut Creek, San Ramon), we recommend a dual fuel system or a cold-climate heat pump rated for low-temperature performance. Coastal areas rarely need any backup heat.
What is a dual fuel heat pump system?
A dual fuel system pairs a heat pump with a gas furnace. The heat pump handles 90–95% of your heating and all of your cooling; the gas furnace activates only when outdoor temperatures drop below the heat pump's efficient range (typically below 35–40°F). This gives you the best of both worlds: electric efficiency in mild weather, gas reliability in the coldest snaps. Dual fuel is a popular choice in inland Bay Area cities.
How do I qualify for heat pump rebates?
Qualifying for rebates requires purchasing a system that meets minimum efficiency standards (typically 15+ SEER2, 8.8+ HSPF2), having it installed by a licensed HVAC contractor, and submitting a rebate application within the required window. Utility rebates (PCE, SVCE, MCE, EBCE/Ava) are available based on your service territory; HEEHRA rebates are income-based. See our full Rebate Guide for current amounts and eligibility requirements.
AC Installation FAQs
How much does central AC installation cost in the Bay Area?
Central air conditioning installation in the Bay Area typically costs $7,500–$14,000, depending on system size, efficiency rating, and whether existing ductwork is being reused. A 16 SEER2 system for a 1,500 sq ft home with existing ducts starts around $7,500–$9,000. Replacing both the AC and furnace at the same time saves $1,500–$2,500 compared to doing them separately.
What SEER2 rating should I choose?
For most Bay Area homes, a 16–18 SEER2 unit offers the best balance of efficiency and cost. Coastal areas with mild summers (San Francisco, Daly City, South San Francisco) typically run AC only 20–40 days per year; a 16 SEER2 unit is usually sufficient. Inland areas that run AC 90–120 days per year (Walnut Creek, Livermore, San Jose) benefit more from 18–20 SEER2 units that pay off faster with heavier use.
Do Bay Area homes need air conditioning?
More than ever. While traditional Bay Area wisdom held that AC was unnecessary, several factors have changed that calculus: heat waves are becoming longer and more intense, climate change is extending summer heat into October, and many Bay Area homes — especially newly built or renovated — have poor ventilation. About 70% of our installations now include AC (up from 45% five years ago).
How often does AC equipment need to be replaced?
Well-maintained central AC equipment lasts 15–20 years in the Bay Area. Signs it's time to replace: your unit is over 15 years old, you're spending $500+ per year on repairs, the system uses R-22 refrigerant (now illegal to manufacture), or you're seeing a significant drop in efficiency. New systems are 30–50% more efficient than 15-year-old units, and the energy savings alone can justify replacement.
Furnace Installation FAQs
How much does furnace installation cost in the Bay Area?
Furnace installation in the Bay Area typically costs $4,500–$9,500 for a gas furnace replacement, or $7,000–$12,000 for a furnace+AC combo. A standard 80% AFUE furnace starts around $4,500 installed; a two-stage 96% AFUE variable-speed furnace runs $6,500–$8,500. We currently offer $3,000 off Furnace+AC system replacements (already reflected in our estimator pricing).
What AFUE rating should I choose for a Bay Area furnace?
For most Bay Area homes, a 96% AFUE furnace is the right choice. California Title 24 now requires 80% AFUE minimum for new installations, but upgrading to 96% AFUE typically adds only $400–$600 to the installation cost while saving $150–$250 per year in gas costs. Two-stage and variable-speed furnaces also run quieter and provide more even heating throughout your home.
Can I still install a gas furnace in California?
Yes — gas furnace installation is permitted in California (including the Bay Area) as of 2025. While some Bay Area cities have adopted local ordinances restricting new gas appliances in newly constructed buildings, gas furnace replacement in existing homes remains legal throughout the region. California's building codes continue to evolve; if you're replacing an existing gas furnace, you remain free to use gas.
How long does a furnace last?
Gas furnaces typically last 18–25 years with annual maintenance. Signs it's time to replace: the furnace is over 18 years old, you're making frequent repairs, your heating bills have increased significantly, you're seeing uneven heating between rooms, or the heat exchanger has cracks (a safety concern). Annual tune-ups extend furnace life and maintain efficiency.
Ductless Mini Split FAQs
How much does ductless mini split installation cost?
Single-zone ductless mini split installation in the Bay Area costs $3,800–$6,500 installed. Multi-zone systems (2–5 indoor units on one outdoor compressor) run $6,500–$14,000 depending on the number of zones. We install Mitsubishi, Daikin, Carrier, and LG ductless systems with 10–12 year compressor warranties.
Where are ductless mini splits used?
Ductless systems are ideal for: garage conversions and ADUs (where running new ductwork is expensive), home additions that aren't connected to the central HVAC system, older homes with no existing ductwork, bonus rooms or bedrooms that are always too hot or too cold, and server rooms or home offices that need independent temperature control.
How efficient are ductless mini splits?
Ductless mini splits are among the most efficient HVAC systems available, with SEER2 ratings of 18–33. They have no duct losses (which account for 20–30% of energy waste in central systems), variable-speed compressors that match output precisely to demand, and individual zone control so you're only conditioning occupied spaces. Most homeowners see 30–50% energy savings compared to window units.
Rebates & Financing FAQs
What HVAC rebates are available in the Bay Area?
Bay Area homeowners can access six programs: the BAAQMD Wood Stove Replacement Program (up to $6,500 for replacing a wood-burning stove or fireplace insert with a heat pump; apply before July 14, 2026); HEEHRA income-qualified rebates (up to $8,000 for low-income, up to $4,000 for moderate-income households) through the California Energy Commission; and utility electrification rebates from MCE (Marin/Contra Costa, up to $400/ton), PCE (San Mateo County), SVCE (Santa Clara County), and EBCE/Ava (Alameda County). Our $3,000 seasonal discount stacks on top. See our Rebate Guide for details.
Can I stack multiple HVAC rebates?
Yes — Bay Area homeowners can stack multiple programs. For example, a San Jose homeowner who removes a wood-burning fireplace insert could combine the BAAQMD Wood Stove Replacement rebate (up to $6,500) + an SVCE utility rebate (up to $2,500) + our $3,000 seasonal discount = up to $12,000 in total savings. Income-qualified households can stack HEEHRA rebates (up to $8,000) on top of that. Our team helps identify all programs you qualify for before installation.
Do you offer HVAC financing?
Yes. We offer multiple financing options including GoGreen Home Energy Financing (low-interest loans through participating California lenders), Peninsula Clean Energy and SVCE financing programs for qualified customers, and 0% interest financing for 12 months on qualifying system installations. See our Financing page for current options and qualification requirements.
Installation Process FAQs
What is the HVAC installation process?
Our installation process: (1) Use our online estimator to get instant pricing. (2) Schedule a free on-site assessment — our technician visits to confirm sizing, assess ductwork, and verify the quote.
