## Common Questions

Q: How much does HVAC replacement cost in the Bay Area?
A: Published planning ranges vary by system from $7,500 to $25,000, depending on system type, home size, and ductwork condition. They are owner-reviewed through October 31, 2026; on or after November 1, 2026, treat them as stale until the owner completes a fresh pricing review. Our online estimator narrows the range for your specific home. Final pricing is confirmed during an in-home assessment.

Q: Do Bay Area cities require permits for HVAC installation?
A: Most HVAC replacements require a mechanical permit. Requirements and fees vary by city or county, so we confirm the local process for the property address, coordinate the permit and inspection where required, and include that scope in the final installation agreement.

Q: What HVAC systems are best for the Bay Area climate?
A: Heat pumps handle both heating and cooling efficiently in the Bay Area's mild climate. Gas furnace + AC split systems remain common for homes with gas infrastructure. Ductless mini splits are useful for room additions, ADUs, and older homes without existing ductwork. Incentive eligibility and availability must be confirmed for the specific project at the time of the assessment.

Q: How long does HVAC installation take?
A: Most standard replacements are completed in one day. Multi-zone ductless systems or projects involving ductwork replacement may take two to three days.
