ZF HEATING & COOLING

ZF Heating & Cooling holds a 5-star rating across three verified reviews in San Francisco. The contractor serves residential customers throughout San Francisco County, Contra Costa County, Alameda County, San Mateo County, Marin County, Santa Clara County, Sacramento County, and Solano County. The company offers installation, maintenance, and repair services for air conditioning systems, heating furnaces, heat pumps, and water heaters.

The contractor provides whole-home air filtration and purification systems to address indoor air quality concerns common in the Bay Area. Additional specialty services include ductless AC installation, dryer vent cleaning, air duct cleaning and sealing, and chimney cleaning. Their service model emphasizes honest communication and skilled workmanship without unnecessary upsells or shortcuts.

Two reviewers specifically mentioned a technician named Fu who handled AC repairs in Dublin and another San Francisco location. One reviewer noted Fu cleaned up thoroughly after the job, even vacuuming the carpet, a detail that emphasized the technician's attention to post-service cleanup. Another reviewer described Fu as showing up on time, working efficiently, and demonstrating care for doing things right. A third review highlighted a technician who performed a thorough diagnostic check instead of guessing, explained the issue clearly, and fixed only what was needed at fair and transparent pricing.
