The Central Valley difference is not one number
Long, hot cooling seasons put more weight on correct cooling capacity, airflow, duct condition, and equipment efficiency. Two homes with the same square footage can have different loads because of window exposure, insulation, ceiling height, shade, leaks, and how rooms are used.
Summer urgency can affect scheduling and labor availability too. That does not make a higher quote automatically wrong. It does make a written scope, a clear timeline, and another comparison more valuable.
What to line up across every proposal
- Cooling and heating capacity, plus the method used to size it.
- Exact model numbers and the matched indoor/outdoor equipment combination.
- Duct repairs, return-air changes, filtration, zoning, and airflow testing.
- Line-set reuse or replacement, electrical upgrades, drain routing, pad work, and disposal.
- Permit responsibility, inspection, startup, warranty registration, and labor warranty.
Rebates can help. They are not a blank check.
PG&E points homeowners to its Heat Pump Buyer's Guide and incentive search tools, including statewide programs. Program funding, equipment requirements, contractor requirements, service territory, and income rules can change. Confirm eligibility before you buy—not after the installation date is on the calendar.
Ask the contractor to name the exact program, qualifying model, expected incentive, and who submits the paperwork. Keep the pre-incentive equipment-and-installation price visible so you can still compare the underlying proposals.
