Sample listings

Every company on this page is a sample listing shown to preview our HVAC and clean air directory. None of these companies has partnered with or paid Open House Ultimate Solutions, and no listing is an endorsement. Once advertising partnerships are in place, paid placements will be labeled as sponsored. Heating, ventilating and air-conditioning work in California requires a Contractors State License Board (CSLB) license with the C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) classification. We checked each license number, status and classification on the CSLB site in November 2026 and left out companies whose license we could not match to the business or confirm as active. Licenses can change, so check again before you hire. Company descriptions come from each company's website.
