Local Factors
Several local factors in Los Altos Hills impact HVAC replacement costs.
- Permits: Santa Clara County requires permits for HVAC replacements. Expect to pay between $300-$800 for permit fees, depending on the scope of the project. Your contractor should handle the permitting process.
- Installation Labor: Due to the high cost of living, labor rates in Los Altos Hills are premium. Expect to pay $75 – $150 per hour for qualified HVAC technicians. Experience and specialization can affect hourly rates.
- Title 24 Compliance: California’s Title 24 energy efficiency standards are stringent. Ensure your contractor is well-versed in Title 24 requirements, including duct sealing and high-efficiency equipment installation. Non-compliance can result in fines.
