Jim Jonas Inc

We serve Lake County homeowners and businesses with heating, air conditioning, solar, and backup-power services. From our Lower Lake location, our team installs, repairs, and maintains heating and cooling systems, works on solar installations and solar-system service, and provides backup-power solutions.

We offer 24/7 local service when comfort or power needs prompt attention. Our work is focused on helping customers keep essential building systems operating through changing seasons and power needs. Whether we are installing new equipment, maintaining an existing system, or responding to a repair, we bring experience across HVAC and solar services to the job.

Families across Lake County have relied on our team for decades. We support projects ranging from heating and air-conditioning work to solar and backup power, with local service available from our Lower Lake base.
