Heat pump recommended for Brentwood
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.
