Core Heating & Air Conditioning

Core Heating & Air Conditioning has served Petaluma and surrounding Sonoma County communities for years, earning a spotless 5.0 rating across 80 verified reviews. Owner-operator John leads the team, bringing a commitment to repair over replacement that reviewers repeatedly praise. The company handles both heating and cooling systems, responding to calls throughout Petaluma with transparent pricing and professional service.

What distinguishes Core Heating from competitors is John's insistence on fixing existing equipment rather than automatically recommending costly replacements. Multiple reviewers specifically note he declined to upsell them on new furnaces, instead explaining each problem and demonstrating repairs that saved hundreds or thousands of dollars. The company maintains low overhead to keep rates competitive while still delivering thorough work, including cleaning components that previous contractors overlooked.

Russel P. experienced this firsthand when his 36-year-old furnace required attention. John arrived the same day, replaced the blower motor, and thoroughly cleaned dirt-encrusted elements that had accumulated over decades. Russel reported his furnace now performs better than it has in the 26 years he has owned his home. Lisa Jepsen needed a new Trane system and found John professional, personable, and offering the best deal in town. Ben Leroi received free furnace inspection alongside his AC repair, with John providing maintenance advice to reduce future service calls.
