Who we are:

We are a family owned heating/airconditioning and solar energy contractor serving the Lake, Napa, and Mendocino county areas

Is doing business with someone you can trust important to you? It's important to most of our customers, and we feel that this is the reason our customers come back to Jonas time and time again. We offer a wide variety of HVAC and Solar Energy products that are specifically tailored to the needs of our unique climate. Because of our many years working in and around Lake, Napa, and Mendocino counties, we can promise you that we understand the unique challenges of engineering efficient systems in our area.
Your project will receive the same level of care, concern, and expertise no matter what its size and complexity. We want you to be satisfied.

We are a positive force in your community.

You live here. So do we. We feel very strongly bringing about positive change in our community. That's why we donate, we participate, and we volunteer.
Our family and staff have been active participants in everything from the local chamber of commerce to volunteering with the local fire department. We've always supported our local kids and their sports teams, and you'll find us helping with local events and organizations. It's all just part of our commitment to the community.

We have served Lake, Napa & Mendocino Counties for over 40 years

Jonas Energy Solutions is a third-generation family-owned company. We take pride in our longstanding history of community involvment in Lake County. Our company was founded in 1973 by Jim Jonas, who moved back to Lake County to take over his father Jack Jonas' Union Oil distributorship. We were, for many years, a heating and fuel oil distributor, employing as many as 40 staff during the peak period of Homestake mining and geyser steam-field activity in Lake County.
Over the years, our natural progression has led to HVAC and Solar energy systems. We have gained a great deal of knowledge over the years about what works, and what doesn't, in our unique climate. We've also made many happy customers and friends along the way! While we no longer sell petroleum products (our fuel business was sold in 2012), we are still priveleged and honored to continue to work with so many of you who have been our customers throughout the years. We are grateful to continue to receive referrals and repeat business from our longtime customers.

We are certified, bonded, and insured

Whether you are purchasing a brand new system, or just need service on your existing system, you can rest easy knowing that all work is being performed by professionals who are licensed, bonded, and properly trained. We are certified by the State of California Contractors Licensing Board for HVAC and Solar-energry systems. All installation and service technicians are factory-trained and certified, and covered by worker's compensation insurance while working on your home. We have a strict drug-free workplace policy.

We Guarantee Our Work

We stand behind every service and product we sell.
We have been serving our community for over 40 years, and we have built a reputation that we are very proud of. Our goal is to maintain this reputation and build on it for years to come.
If for any reason you are not satisfied with our work or any product we sell, we will do whatever it takes to make you satisfied, including replacing it with an equal value system or removing your system and refunding 100% of your money.

We are here when you need us

Before you make your next HVAC or Solar purchasing decision, we just want you to consider one thing: Will your installer be around when you have a problem? Will they pick up the phone when you call them at an innopportune moment? With Jonas, you can answer YES to both of these questions. We are one of the only contractors in our area that offers true 24-hour service, along with a local presence that guarantees we'll be there within a reasonable amount of time.
We have a modern, fully-computerized scheduling system, and enough technicians and installers to do the work. We won't forget you, and we won't let you down. That's what we mean when we say 'We're here when you need us!.'
