How long does heat pump installation take?
A straightforward heat pump replacement (swapping an existing system) typically takes 1–2 days. A new installation requiring ductwork modifications, electrical upgrades, or multi-zone ductless setup may take 2–5 days. Your installer should provide a clear timeline before the project begins.
What’s the best heat pump brand for Bay Area homes?
Top heat pump brands for Bay Area installations include Mitsubishi (excellent mini-splits), Daikin (high efficiency), Carrier (reliable and widely serviced), Lennox (quiet operation), and Trane (durability). The best brand for your home depends on your specific needs, budget, and whether you need ducted or ductless. A qualified installer will recommend the right fit.
Do I need to upgrade my electrical panel for a heat pump?
Many older Bay Area homes (pre-1990) have 100-amp or 150-amp electrical panels that may need an upgrade to 200 amps to support a heat pump. This typically costs $1,500–$4,000.
