For qualifying households (under 150% of Area Median Income):
- Heat pump HVAC: Up to $8,000
- Heat pump water heater: Up to $1,750
- Electrical panel upgrade: Up to $4,000
Money-Saving Strategies
1. Maximize Available Rebates
A heat pump installation that costs $20,000 upfront might net:
- Federal tax credit: -$2,000
- TECH rebate: -$2,000
- PG&E rebate: -$1,000
- Net cost: $15,000
2. Install During Off-Season
| Season | Typical Wait Time | Pricing |
|---|---|---|
| Winter (Emergency) | 1–3 days | Premium (+10–25%) |
| Summer (Peak) | 1–2 weeks | Standard |
| Spring/Fall | 2–5 days | Best deals available |
Best time: March–May or September–October. Less demand means better scheduling and sometimes lower prices.
3. Keep Existing Ductwork If Possible
New ductwork adds $5,000–$12,000+ to any project. If your ducts are in reasonable condition, having them sealed and cleaned is much more cost-effective.
4. Consider the Total Cost of Ownership
A $16,000 system with 14 SEER2 vs. a $19,000 system with 18 SEER2:
- The higher-efficiency system saves ~$200–$400/year on energy
- Over 15 years: $3,000–$6,000 in savings
- Plus: Qualifies for higher rebates

Why Bay Area Costs Are Higher Than National Averages
If you've searched "HVAC cost" online, you've probably seen national averages of $5,000–$10,000. Those numbers don't apply to the Bay Area. Here's why:
1. Mandatory Permits & Inspections
Every HVAC installation in California must be permitted. Cities charge $200–$500 for permits and require inspections. This adds cost but protects you—unpermitted work causes problems when selling.
2. California Licensing Requirements
California requires a C-20 HVAC license for all heating and cooling work. This means properly trained, insured, and bonded contractors—not handymen.
3. Title24 Energy Compliance
California's strict energy code requires documentation, specific equipment ratings, and verification testing. This is extra work, but it ensures your system is efficient.
4. Higher Labor Costs
Bay Area cost of living means technicians earn more than in other regions. Quality technicians are worth it—poor installation causes years of problems.
5. Seismic Requirements
Earthquake bracing and proper installation methods are required in California. This adds modest cost but provides important safety.
6. Environmental Regulations
California has stricter refrigerant and emissions standards than most states. Compliance requires specific equipment and procedures.
Bottom line: Higher costs reflect professional, permitted, code-compliant work. It's not overpriced—it's the real cost of doing it right.
Frequently Asked Questions
Q: How long does HVAC installation take?
Most installations complete in 1–2 days. Complex installations with new ductwork or electrical upgrades may take 3–5 days. Learn about installation preparation →
Q: Should I replace my furnace and AC at the same time?
If both systems are 15+ years old, yes. Matched systems work better together, you save on labor costs, and you avoid disruption from two separate installations.
Q: Can I finance an HVAC system?
Yes. Most contractors offer 0% financing for 12–60 months. PACE financing is available for energy-efficient upgrades. HVAC financing options →
Q: How do I know if I'm getting a fair quote?
Get 3 quotes for the same equipment. Compare what's included—permits, warranty, equipment brand/model, electrical work. The lowest quote isn't always the best value. How to compare HVAC quotes →
Q: What's the difference between SEER and SEER2?
SEER2 is the newer efficiency rating standard (started 2023). It uses more realistic testing conditions and produces lower numbers. A SEER2 15 is roughly equivalent to the old SEER 16. SEER2 explained →
Q: Is it worth getting a heat pump instead of a furnace + AC?
For most Bay Area homes, yes. Heat pumps provide both heating and cooling, qualify for larger rebates, and have lower operating costs. Heat pump comparison guide →
Q: How long should an HVAC system last?
Quality systems typically last 15–20 years with proper maintenance. Budget systems may last 12–15 years. When to replace your HVAC →
Q: What maintenance does a new system need?
Annual professional tune-ups (fall for heating, spring for cooling) and monthly filter changes. Most manufacturers require annual maintenance to keep warranties valid. Air filter guide →
