| High-Efficiency AC | SEER2 Rating 16-20, Better cooling, energy savings | $9,000 – $12,000 |
| Heat Pump (Entry Level) | Provides both heating and cooling, replaces furnace and AC, entry-level efficiency. | $8,000 – $12,000 |
| High-Efficiency Heat Pump | Advanced features, quieter operation, better temperature control, higher SEER2 and HSPF ratings (significant rebates). | $12,000 – $16,000+ |
Local Factors Affecting HVAC & AC Replacement Costs
- Permits: Santa Clara County requires permits for HVAC and AC replacements. The cost varies, but budget around $500-$1000 for permit fees and inspections.
- Installation Labor Rates: Due to the high cost of living in Mountain View, labor rates are higher than the national average. Expect to pay between $75 and $150 per hour for qualified HVAC technicians.
- Title 24 Compliance: California’s Title 24 energy efficiency standards are strictly enforced. This means your new system must meet specific requirements for duct sealing, insulation, and overall energy performance, which can increase installation costs.
- Heat Pump Rebates & Tax Credits: Take advantage of the Inflation Reduction Act and California state rebates for installing a high-efficiency heat pump. These can significantly reduce your upfront costs. Consult with your contractor to determine eligibility.
- CSLB Licensing: ALWAYS verify your contractor’s license through the California Contractors State License Board (CSLB). Unlicensed contractors can lead to fines and voided warranties.
Weather Impact on HVAC & AC Replacement Efficiency
Mountain View experiences warm, dry summers. This climate puts a significant strain on cooling systems. Upgrading to a high-efficiency heat pump is highly recommended. Heat pumps are significantly more energy-efficient than traditional AC units and can provide both heating and cooling, making them ideal for our climate. They also contribute to cleaner air and reduced reliance on fossil fuels, aligning with California’s environmental goals. Moreover, consider upgrading to MERV 13 filters or installing an air scrubber to combat wildfire smoke and improve indoor air quality.

Frequently Asked Questions
- How long does HVAC/AC replacement take? Typically, a standard AC or furnace replacement takes 1-3 days, depending on the complexity of the job and any necessary ductwork modifications. Heat pump installations might take slightly longer, especially when retrofitting from an older gas furnace system.
- What SEER2 rating should I choose? Aim for a SEER2 rating of 16 or higher to maximize energy savings and qualify for rebates. A higher SEER2 rating translates to greater energy efficiency and lower utility bills.
- Should I replace my furnace and AC at the same time? If both your furnace and AC are old (10+ years) or nearing the end of their lifespan, it’s generally more cost-effective to replace them simultaneously. This also ensures optimal system compatibility and performance.
