Energy Storage in the Bay Area

"Our solar was installed on our house earlier this year. I found Nick and Green Air to be extremely professional, responsive to questions and started and completed the job on time. Nick has a very strong work ethic and was competitive in his pricing as compared to other companies. It’s also nice to know that PG & E is now my customer!"

"Nick Donzelli and Green Air have taken great care of me and my home. The knowledge and ability to tailor specific systems to your home is above all other similar companies I have seen in this industry. Great service, great follow-through."

"We can’t speak highly enough of Green Air. They have put in our Tesla backup house batteries, our solar rooftop system, and heat pumps. So you can see, we have used them three times now and each time it has been a delight: their work was done properly, efficiently, and was reasonably priced. Their service is exceptional. Absolutely delightful to work with them. Workpeople and ownership are great and responsive. We give them our highest recommendation."

"Nick and Green Air just installed 9.1kW rooftop solar (21 Maxeon panels), two Tesla PowerWall+, a Tesla Inverter/Gateway, and two SPAN panels, and all of this communicates together controlled by the Tesla app. I had a friend who installed this rig, and frankly, Nick was the only vendor who thoroughly understood it and had experience. Green Air was timely, clear, estimates and invoicing were clear and accurate, professional, the installation and conduit routing were very well done and looked great, and the team members were friendly and courteous. I couldn’t be any happier, I’d like to give it six stars. ..."

"These guys actually know what they are doing and do what they say they are going to do. They are capable in many areas including installing solar panels, Tesla batteries, and also HVAC. They complete the whole job with their own employees rather than using outside contractors. We were really pleased with the results on three separate jobs. Thanks."

"In December we started to gather some quotes from local companies for a new Heater and A/C (and not too thrilled with the lack of expertise), I decided to look a bit further away from our city (Brentwood). I stumbled across Green Air and also noticed a friend of mine used them! They were very professional during the quote process and walked and talked us through everything! Fast Forward: About two weeks ago our A/C broke down (was about time). We had already set everything up with Green Air, but we didn’t expect the A/C to break down. After we ..."

"I’ve been a customer of Green Air for over 10 years. I just recently had them come out for service on my HVAC system for my annual maintenance which I have them do every Fall. Most years everything is fine, but this year they found a minor issue that needed to be addressed and took the time to show me the problem and educate me on the corrective action and why it needed to be fixed. As a homeowner, I understand HVAC systems need work from time to time, not every contractor has skilled employees like Green Air who take ..."

"Green Air installed a 15kw solar panel system, 3 power walls, all new duct work for our central air system, and repaired 2 furnaces. From the beginning of our contact, Green Air has always been very responsive in all forms of communication (email, text, and phone calls) and professional. Our solar system was installed within 2 weeks of contract signing, and we have not had any issues with roof leaks, or solar panels not working. During this current supply chain crisis, Green Air was able to fix both of our furnaces during the coldest months of the winter by securing ..."
