South Bay Climate
Hot, dry summers (90s-100s) and mild winters. Significant cooling demands with moderate heating needs. Most different from San Francisco's climate.
Newer Home Considerations
Post-1990 homes often have adequate ductwork and insulation. Focus on equipment efficiency—upgrading to 18+ SEER provides good ROI.
Older Eichler and Ranch Homes
Mid-century homes often have radiant heating and no AC. Adding cooling requires creative solutions—mini-splits or attic-mounted systems.
Townhomes and Condos
Shared walls affect heat loss. Interior units need less heating but may lack natural ventilation. Ensure HVAC can handle summer heat.
New Construction Standards
California's Title 24 requires efficient equipment in new homes. Heat pumps are increasingly standard. Ensure you understand your system.
Water-Saving Considerations
Evaporative (swamp) coolers don't work well in Silicon Valley's dry heat. Stick with refrigerant-based cooling.
