Coastal Peninsula: Daly City to Pacifica
Fog and mild temperatures dominate. AC is rarely needed. Heat pumps provide efficient heating without the cooling capacity waste.
Mid-Peninsula: San Bruno to Burlingame
Protected from fog but cooler than inland. Balanced heating and cooling needs make this area ideal for heat pump systems.
Central Peninsula: San Mateo to Redwood City
Warmer than coastal areas, especially in summer. Standard heating and cooling needs. Efficiency matters as usage is moderate year-round.
Bayside Peninsula: Foster City to Menlo Park
Bay breezes moderate temperatures. Humidity can be higher. Dehumidification capability is valuable in these areas.
Southern Peninsula: Palo Alto to Los Altos
Warmer and sunnier. More significant cooling needs. Higher-SEER equipment and smart shading strategies pay off.
Mountain Areas: Woodside to Portola Valley
Significant variation between sun and shade, valleys and ridges. Site-specific assessment is essential—neighbors may have very different needs.
