Our Affiliations & Certifications

The equipment we install is only as good as the people and manufacturers behind it. Over the years, we've built strong relationships with some of the most respected names in heating, cooling, solar, and backup power.

These partnerships mean we can offer you proven, reliable systems — and back them with manufacturer warranties and factory-trained expertise. They also reflect the standards we hold ourselves to on every job.

As a fully licensed contractor (California license #708935), we carry the credentials to handle solar, HVAC, and electrical work under one roof, serving Lake County and El Dorado County.

Brands We Trust and Install

We choose our manufacturer partners carefully, favoring companies known for efficiency, durability, and strong warranties. When you work with us, you're getting equipment we'd be comfortable putting in our own homes.

• Mitsubishi Electric — including our status as a Diamond Contractor for ductless mini-split systems
• American Standard — dependable, high-efficiency HVAC systems
• Generac — whole-home standby generators and backup power
• Plus trusted solar, battery, and water heating equipment from leading manufacturers

Mitsubishi Diamond Contractor

Our Diamond Contractor designation is one we're especially proud of. It's earned by contractors who complete advanced Mitsubishi training and demonstrate real expertise in designing and installing ductless mini-split systems.

For you, that means expert system design, correct installation, and access to enhanced Mitsubishi warranty coverage on qualifying systems.
