Cloud 9 Heating & Air

Cloud 9 Heating & Air operates as a fully licensed HVAC contractor serving Seattle, Bellevue, and neighborhoods throughout King County. With a flawless 5-star rating across 25 verified client reviews, the company has built its reputation on transparent communication and meticulous installation standards. The team holds current Washington state licensing and maintains manufacturer certifications required for warranty-backed work on leading equipment brands.

This contractor earned the 2025 Mitsubishi Diamond Contractor of the Year award, a distinction held by fewer than 1% of Mitsubishi dealers nationally. That credential translates to direct access to heat pump models with hyper-heating capability, engineered specifically for Pacific Northwest temperature swings. The company also handles tankless water heater installations, providing a single point of contact for homeowners upgrading both heating systems and domestic hot water without coordinating multiple contractors.

Homeowners consistently mention Brent, Mike, and Ryan by name in reviews. One client described calling about a diagnostic issue and receiving phone-based troubleshooting from Brent and Mike, service that avoided a service call altogether. Another review recounts a same-week system replacement where the crew completed installation in two work days after the homeowner received multiple bids. The team returned multiple times to investigate a condensation concern that ultimately originated from a refrigerator, not the HVAC system, demonstrating commitment that extends beyond the original scope.
