Customer Reviews

Mike N

“ Nick is very well educated on the products industry. He has been in the industry for years now and knows more than anyone else I have spoken to. Its very refreshing to have the owner of the company come out to talk to you about your options compared to a door to door sales guy who cant even answer the most basic questions. Im very happy with the service and attention to detail “

Tobi M

Nick and Green Air installed our Solar One year ago, it has exceeded its projected output and works great! The work was started and completed on time and Green Air completed all the extra work such as getting permits from the city of Benicia. Green Air employees cleaned up their work site daily and they were a pleasure to work with. I love the fact that we have shrunk our carbon footprint.

Michael M.

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!

Brett B.

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.

Sam S.

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 ...

Philip K.

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 ...

Jon K.

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.

Garrett F.

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 ...

Tom L.

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 ...

Gillian W.

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. ...

Allen P.

Had Nick install solar about 8 years ago. Everything went exceedingly well. Since then, I have referred many friends and acquaintances to Green Air. As a business owner, this is something I almost never do. Green Air has been out a few times since then to repair things on my old HVAC system. Most recently yesterday. They have always shown up at the promised time and done everything they could to get me back up ...

James W.

We did a major remodel of our home and Green Air did an exceptional job on various aspects of our remodel. They installed solar panels on the roof + a battery storage system, repaired both of our furnaces and both of our ACs, installed brand new HVAC throughout the whole house with individual zones, installed the downdraft in our kitchen for our stove, and installed a heat pump for our pool. Every installation they did ...

Christopher A.

Nick, Jayman, Alex, and Francois are the best. We had the usual new tech issues with the heat pump and solar battery, and they were always here to help out and set things right. Several years after the installation too.

Scarlett C.

The Green Air team was wonderful. I was very nervous about choosing a company to install my solar panels and system. They not only took the time to explain things in a way I could easily understand, but they kept me in the loop for every step of the process. The work was done quickly and without hassle. Fair pricing compared to other companies I had reached out to. I will definitely be utilizing them ...

Mendel D.

My family and I have lived in Concord for about 4 years with NO air conditioning! Green Air was recommended to us by my husband’s co-worker who recently had solar installed by Green Air. They came highly recommended! They not only install solar, but they also provide HVAC installs. Our house is old, with no HVAC ducts, just wall heaters (terrible!). Nick, the owner of Green Air came to our house for a quote, at ...

Eli N.

Nick and his team handled a large project for us in Aug of 2018. It started with Nick coming over to look at my furnace that just went out. Nick gave me some honest feedback and some options. During the visit, he did not once mention he does roofing and solar. I point this out as a positive as I never once felt like he was selling me. He simply informed me of my options ...

Jennifer L.

We’ve been using Green Air for several years now – and we contacted Green Air just before the holidays because our HVAC was only blowing cold air. Our request was responded to the same day, and Nick was out to inspect and troubleshoot the system within a day of response. After inspection replacement parts were identified/needed, so Nick informed us he would contact Lennox to order the parts and be back out. We knew since ...
