Why HVAC matters in El Cajon
El Cajon 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.
CA (San Diego County) falls in IECC 3C-Warm-Marine. HDD 2600 / CDD 500 per NOAA 1991–2020 state averages drive a heat pump dominant HVAC strategy. Climate data is zone-level; consult a contractor for site-specific load calcs.
Heat pump recommended for El Cajon
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.

San Diego Gas & Electric (SDG&E)'s SDG&E Heat Pump HVAC Rebate (TECH Clean California) currently offers up to $3,000 toward a qualifying system, which meaningfully shifts the cost-of-ownership math.
