Considering an HVAC or AC replacement in South San Francisco? You’re likely looking at a project costing between $8,000 and $16,000 for a full system replacement. This significant range is due to several factors, including the size of your home, the type of system you choose (more on that below!), efficiency ratings, ductwork condition, and the contractor you hire.

Material Prices: Understanding Your Options (and the Heat Pump Advantage)
While traditional AC systems and gas furnaces were the norm, California’s pushing hard for electrification. In 2026, the best choice is usually a heat pump. Heat pumps offer both heating and cooling, and the state is offering serious incentives to switch!
| System Type | Average Cost (Installed) | Notes |
|---|---|---|
| Heat Pump (Full System) | $9,000 – $16,000 | Highly efficient, qualifies for rebates. Best option for 2026. Consider SEER2 ratings for maximum savings. |
| Central AC + Gas Furnace (Split System) | $8,000 – $14,000 | Less efficient than heat pumps; may not qualify for as many rebates. Less future-proof. |
| Ductless Mini-Split (Single Zone) | $3,000 – $6,000 | Good for additions or rooms without existing ductwork. Heat pump models available. |
Local Factors: South San Francisco Considerations
- Permits: San Mateo County requires permits for HVAC replacements and installations. Your contractor should handle this process. Failure to obtain permits can result in fines and delays.
- Installation Labor Rates: Labor costs in the Bay Area are high. Expect to pay a premium for experienced and licensed HVAC technicians. Be sure to get multiple quotes.
- CSLB Licensing: It is crucial to verify your contractor’s license at the California Contractors State License Board (CSLB). Unlicensed contractors can lead to shoddy work and hefty fines.
- Title 24 Compliance: All new HVAC systems MUST comply with California’s Title 24 energy efficiency standards. This includes proper duct sealing to prevent air leaks and ensure optimal performance.
Weather Impact & Indoor Air Quality
South San Francisco enjoys a relatively mild climate, but summers can still bring periods of warm weather. An efficient AC system is crucial for maintaining comfort. More importantly, with increasing wildfire risks, focusing on Indoor Air Quality (IAQ) is paramount. Consider these factors:
- Energy Efficiency: Opt for a high-efficiency system (look for SEER2 ratings) to reduce energy consumption and lower your utility bills.
- Heat Pumps for All Seasons: A heat pump provides efficient heating during cooler months and reliable cooling during warmer periods.
- IAQ Solutions: Invest in high-efficiency MERV 13 air filters to capture smoke particles and other pollutants. Consider adding an air scrubber to your system for enhanced air purification.

FAQ: HVAC & AC Replacement in South San Francisco
- How long does an HVAC replacement take? Typically, a full system replacement takes 1-3 days, depending on the complexity of the installation and any necessary ductwork modifications.
- What SEER2 rating should I look for? Aim for a SEER2 rating of 16 or higher to maximize energy savings and qualify for rebates. The higher the SEER2, the more efficient the system.
- Are there rebates available for upgrading to a heat pump? Yes! California and the federal government (via the Inflation Reduction Act) offer significant rebates and tax credits for installing energy-efficient heat pumps. Your contractor can help you navigate these incentives.
