Why HVAC matters in Redwood City
Redwood City sits in IECC climate zone 3C-Warm-Marine with average January temperatures of 52°F and July highs around 68°F. The moderate climate makes heat pumps an efficient choice for year-round comfort.

Heat pump recommended for Redwood City
An air source heat pump is the ideal system for this climate zone — it heats in winter and cools in summer with one unit.
With mild winters (avg 52°F in January) and 2,600 heating degree days, heat pumps operate at peak efficiency year-round here. California's Title 24 and the CARB Zero-Emission Space & Water Heater rulemaking are steering new-construction and replacements toward heat pumps; many jurisdictions have local reach codes that restrict new gas hookups.
About Redwood City HVAC

Redwood City's climate (IECC zone 3C-Warm-Marine) keeps outdoor temps inside the efficient range of air-source heat pumps most of the year, with January averages around 52°F. That's why heat-pump conversions have overtaken straight AC + furnace installs in most of the local market. Pacific Gas & Electric (PG&E)'s PG&E Heat Pump HVAC Rebate (TECH Clean California) currently offers up to $3,100 toward a qualifying system, which meaningfully shifts the cost-of-ownership math.
