Cardinal Heating & Air

What Cardinal Heating & Air does

Cardinal Heating & Air, operating legally as Cardinal Heating, Air & Plumbing, is a privately held residential and light-commercial home services contractor founded in 1991 and headquartered at 13649 NE 126th Pl Suite 101 in Kirkland, Washington. The company delivers installation, repair, and maintenance across four core trades: heating (furnaces, boilers, heat pumps, geothermal), cooling (central A/C and ductless mini-splits), plumbing (burst pipes, water heaters, tankless systems, gas lines, leak detection), and residential electrical (safety inspections, EV chargers, generators, surge protection). Field operations are managed through the ServiceTitan platform, and the company holds Washington State contractor licenses (M-17953 and TACLB136431E), a Mitsubishi Diamond Contractor designation, and Trane technician certifications.

The company operates a direct-to-consumer go-to-market model targeting homeowners in King County and Snohomish County, covering approximately 13 cities across the Greater Seattle area. Customer acquisition runs through the company website (online quote forms), phone-based booking, and organic search driven by a 4.7-star rating across 513+ Google reviews and an A+ BBB rating held since 2008. Revenue is generated on a per-job basis across three service lines (HVAC, plumbing, electrical), supplemented by same-day emergency service available 24/7 and consumer financing options (0% APR on qualifying systems, plans starting at $89/month, and a flat $99 same-day plumbing diagnostic for new customers). No dealer, franchise, or partner reseller network is used; all services are delivered by in-house licensed technicians traveling to customer sites.

The business is independently owned with no disclosed parent company, subsidiaries, external investment, or M&A activity. Employee count is in the 11–50 range, revenue is not publicly disclosed, and there are no documented funding rounds. The core value proposition centers on local reputation, multi-trade convenience, and around-the-clock availability rather than proprietary technology or differentiated AI capabilities.
