Horizon Heating & Air Conditioning, Inc. operates as a family-owned heating contractor headquartered in Anaheim, California, serving the greater Orange County region. With a perfect 5.0-star rating across 8 client reviews, the company handles new system installations, replacements, preventive maintenance, and commercial HVAC projects. Their service offerings extend into indoor air quality solutions and specialty niches including coastal HVAC corrosion protection coating and in-house sheet metal fabrication. Dave, the company owner, remains personally involved in project estimates and installations, maintaining direct oversight over every job. Working hours run Monday through Friday from 7 AM to 4 PM, with weekend availability closed.

What distinguishes Horizon from many regional competitors is their investment in specialized capabilities that most residential contractors outsource. Their in-house sheet metal fabrication shop enables custom ductwork modifications without third-party delays, while their coastal HVAC corrosion protection coating addresses a specific challenge facing Orange County homeowners near the Pacific. The company operates as a Lennox dealer offering equipment from recognized manufacturers, and they structure payment to homeowner satisfaction, collecting only after work is completed rather than demanding upfront deposits. Extended warranties and service agreement programs provide ongoing value beyond the initial installation phase.

Reviewers repeatedly highlight owner Dave by name for his hands-on approach and honest estimates. Christine Martin in Anaheim noted that Dave provided no aggressive sales tactics, simply delivering a quality installation with a crew that left zero debris. Jasmine Moini brought in Horizon after a previous contractor failed to resolve her heating and cooling problems, finding that Dave conducted a thorough assessment and submitted the lowest bid among five competing estimates. Tim Folkers appreciated that Dave and his crew finished his heater replacement in a single day, protecting carpets with drop cloths throughout the process. Linda McDonel described the team as professional and efficient during her AC and thermostat relocation project.
