About Schmitt Heating & Air Conditioning
Schmitt Heating & Air Conditioning holds a 4.2-star rating from 57 verified reviews, establishing solid credibility within San Francisco's competitive HVAC market. The contractor operates across four Bay Area counties: San Francisco, Alameda, Marin, and San Mateo, serving both residential households and commercial properties. Business hours run Monday through Friday from 7 AM to 4:30 PM, with same-day emergency availability demonstrated across multiple reviewer accounts. The company maintains Carrier dealer status and offers equipment from additional major manufacturers including Lennox, Mitsubishi, and Daikin.
What distinguishes Schmitt from neighboring contractors is their specialized expertise in server room air conditioning, a niche rarely offered by residential-focused companies. Their indoor air quality division incorporates Carrier's REME HALO technology for whole-home purification, addressing a growing concern for Bay Area homeowners concerned about wildfire smoke and urban pollution. The Comfort Club membership program provides annual maintenance agreements, with one reviewer securing preventive service for a 20-unit building's rooftop fans. Commercial design services enable customized system specifications for businesses requiring precise climate control beyond standard residential solutions.
Reviewers consistently highlight specific technicians who resolved challenging situations. During the February 2024 cold snap, Saul arrived at a condo with an 85-year-old furnace and provided competitive quotes for both the affected unit and a neighboring property's replacement. A different reviewer credited technician Bryant for returning twice to diagnose a recurring thermostat issue, ultimately replacing the defective unit at no charge. Adrian earned praise for explaining furnace and AC diagnostics clearly to a homeowner whose three-year-old system had never received professional service. These scenarios demonstrate the contractor's capacity for both routine maintenance and complex troubleshooting.
What Customers Say
All seven named reviewers awarded 5-star ratings, with four explicitly mentioning same-day or emergency response during weather extremes. Two reviews highlight commercial capabilities spanning multi-unit buildings, while three specifically praised individual technicians by name for patience, thoroughness, and follow-through.
