The temperature difference between the Embarcadero and Glen Park on the same afternoon can reach 20 degrees. Fog acts as natural air conditioning in western neighborhoods, meaning homes in the Sunset often need smaller systems than identical homes in Noe Valley. Load calculations must account for your specific microclimate, not citywide averages. A 3-ton unit that works in Bernal Heights will overcool a Richmond District home, causing short-cycling and humidity problems. We measure historical temperature data for your neighborhood and adjust tonnage recommendations accordingly.
San Francisco's Department of Building Inspection requires permits for all central air installations and enforces Title 24 energy compliance. Contractors who skip permitting expose you to fines and complications during property sales. We maintain relationships with city inspectors and understand current code interpretations, which change annually. Our installations meet seismic bracing requirements for rooftop and exterior-mounted equipment. We follow noise ordinance limits for condenser placement near property lines. Choosing a contractor familiar with San Francisco regulations prevents costly rework and legal issues down the road.
