In San Francisco, high energy bills are often linked to older, inefficient HVAC systems working harder due to the city's cool nights and variable temperatures. A common local culprit is a clogged air filter, which restricts airflow and forces your system to run longer. We recommend starting with our preventative maintenance check, which includes filter inspection/replacement, duct sealing, and system calibration. This service can identify inefficiencies and help restore your system's performance, potentially lowering your monthly costs.
