Walnut Creek recorded 119°F during the 2022 heat wave — among the highest temperatures ever measured in the Bay Area — making robust air conditioning a non-negotiable necessity. The city's higher-end homes tend to have larger HVAC systems, and the extreme heat demands properly sized equipment that can maintain comfort at 110°F+ outdoor temperatures. Near the Hayward Fault, seismic considerations influence equipment mounting and gas line connections.
