Baier Heating and Air Conditioning, Inc.

Baier Heating and Air Conditioning, Inc. has served Rohnert Park and the broader North Bay area for decades, holding California contractor license 1001504. The family-owned business holds a 4.5-star rating from 15 verified reviews and provides residential and commercial HVAC services across Sonoma County, Napa County, Solano County, and portions of Alameda and San Mateo counties. Their service territory spans Rohnert Park, Petaluma, Santa Rosa, Healdsburg, Mill Valley, Novato, San Rafael, Sebastopol, and Windsor. Operating Monday through Friday from 8 AM to 5 PM, the company employs technicians including owner Chad and Scott, who handle installations, repairs, and system design for homeowners and business owners alike.

What distinguishes Baier Heating is a rare combination of in-house sheet metal fabrication and responsive service. Owner Chad operates a custom sheet metal shop capable of building specialized mounting hardware when an installation requires non-standard solutions. The company is a Lennox dealer, offering residential systems backed by a nationally recognized manufacturer. For homeowners pursuing heat pump upgrades, Baier Heating can guide clients through available utility rebate programs to offset installation costs, a detail that matters when replacing aging equipment. These capabilities position the company to handle both routine replacements and technically demanding projects that other contractors decline.

Reviewers named technician Chad multiple times for his hands-on problem-solving during specific challenges. Customer Kenny Price needed a new rooftop unit that required custom sheet metal fabrication; Chad built the mounting brackets in-house, and Price described the result as working perfectly. During a 105-degree heat wave, customer Chad Asay lost air conditioning and called Baier; the crew arrived the next morning and fixed the system immediately. Positive reviews consistently cite emergency response capability, thorough installation work, and respectful treatment of the homeowner's property. One reviewer mentioned that Baier would not return calls regarding a unit purchased three years earlier, the sole critical review among fifteen.
