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, two SPAN panels, and all of this communicates together controlled by the Tesla app. I had a friend that installed this rig, and frankly, Nick was the only vendor that thoroughly understood it and had experience. Green Air was timely, clear, estimates and invoicing were clear and accurate, professional, the install and conduit routing is very well done and looks great, and the team members friendly and courteous. I couldn't be any happier, I'd like to give six stars. We just had an all day PG&E outage, and this system flawlessly kept everything running. Solar is not just about saving energy costs, it is also about reliable power and energy backup (without requiring gas like a generator). They were very helpful on Solar Credits, and our tax rebate of 30% made it very affordable! I can recommend them highly.

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 the time to truly inspect your system, and go beyond by providing the information needed to make an informed decision.Services: HVAC system maintenance, Heating system repair, Repair HVAC

In December we started to gather some quotes from local companies for a new Heater and A/C (and not to 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 week ago our A/C broke down (was about time). We had already had set everything up with Green Air, but we didn't expect the A/C to break down. After we returned from a camping trip I called Nicholas to see if we could move up our build date. Obviously with the Heat Wave coming, I didn't think they would be able to squeeze us in. To our good fortune Nicholas called us back and in two days they would start the process (thank you!!!!). They came out on a Thursday and Friday to work on the job (mind you this was the severe heat 105-110 temperatures). Alex and Derrick not only worked for two days in those horrendous temperatures but they were very professional and polite the entire time!We had a dual zone heat pump installed and compared to our old A/C this is so quiet! We also had Green Air add some solar to the house!The entire process with Green Air was very smooth and very professional!100% would recommend Green Air!

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, they repaired both of our furnaces and both of our AC’s, installed brand new HVAC through 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 was very professional, on time, and they always answered all of our questions with great detail (at all hrs of the day!). We have never had any issues with our systems and it has been 1 year since everything was done. The Green Air team continues to provide great customer service!Services: HVAC system maintenance, Heating system repair, Installation, Roof repair, Repair HVAC, Roof installation

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 the this current supply chain crisis, Green Air was able to fix both of our furnaces during the coldest months of the winter by securing rare parts so that we wouldn't freeze in our own home. Green Air's team has always been on time, very professional, and everyone has always provide excellent customer service.Services: Heating system repair, Installation, Repair HVAC

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 and running in the shortest possible time. Prices are reasonable, everyone at the company is honest, and the service is excellent. A very good combination.Services: Installation, Repair HVAC

Green Air did a great job for us installing our Tesla Powerwall in 2020, and they have been there for us since. We have solar panels that are not from Tesla, and they worked very cooperatively with our solar installer to make the system work. We have not had any issues since the installation until recently, when Verizon discontinued 3G wireless support, and Tesla switched to a Wifi connection for their gateway to the web. Problem was, and is, that the Wifi connection on the version 1 Tesla gateway isn't stable - just won't stay connected. Tesla customer service said yeah, we have about 7,000 customers in that situation....but stopped there. No solution offered other than to make it a wired ethernet connection to the gateway. Enter Green Air to the rescue! They came out today and helped with poking a hole in an exterior wall, and opening up the gateway to make the connection. I appreciate knowing that Green Air will be there for any future problems, and highly recommend them. Go Solar! Go Green Air!

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 install too.

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 for maintence and often reccomend them to friends and family looking for solar and hvac. Thank you Green Air.Service: Installation

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!

this is the worst company in the bay area. they installed a heater at my home, in fact two heaters. they don't work after a few months and then they deny the installer the heart and refuse to repair it. just horrible experience all around, damn it

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, they also provide HVAC installs. Our house is old, no HVAC ducts, just wall heaters (terrible!). Nick, the owner of Green Air came to our house for a quote, at first we were all in for HVAC with duct work. Well Nick gave us a quote for traditional (ducted) HVAC and ductless HVAC with solar. Nick's quote was too good to pass up. We ended with ductless HVAC and solar. Nick had great communication skills that my husband and I did not feel pressured or "out of the loop" . He made sure that all our questions and concerns were addressed before the project started. His crew came on time every day and they treated our house with respect. I observed the crew work well with one another (great team chemistry). They did a "clean cut" job and were very efficient. Nick followed up with us everyday of the project. He made sure that we were completely satisfied with the outcome of our project.We now have ductless Air conditioning and Heating throughout our home. Also we have solar as well. Our ductless system is powered fully by electricity therefore cutting down on our gas bill. Our solar will help decrease our electricity bill, too. Although many may shy away from a ductless system, due to the units that hang on the wall. I personally don't mind at all.I would definitely recommend Green Air to any of my family and friends. We are so happy that we had Green Air complete our HVAC and solar needs.They get the job done right! Thank you Nick and his amazing crew (Aziz, Frank, Jeremy, Jimmy sorry if i left anybody out), you guys are awesome!

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 on my options and potential costs. After some follow up discussion I then discovered he also offers solar. We ended up penciling out the cost and it made sense to make the move to solar. As we were getting ready to start we ran into issues with my roof. Concerned on what to do, Nick was able to provide a solution and at a reasonable cost. Again I point out that not once did I fee pressured to move forward with the project. Ultimately his team was able to install a custom HVAC system, upgrade my roof, and install solar. I wanted to wait at least a year to provide a review so that I could check my actual electricity saves to what was being projected. Turns out Nick was right on the money. The size of my solar project is producing the expected savings and my roof looks great. Nick has always been available for follow up questions and really seems to be passionate about his work. He has a is very knowledgeable about the costs and tax credits. I highly recommend talking to Nick if you have any HVAC or Solar needs.

Solar was a big investment for us and was something we knew nothing about other than it was supposed to help save money on our utilities. Green Air walked us through every phase from purchase through installation and made the whole process easy, quick, and professional.Four stars because a little more guidance and knowledge on after installation would have been helpful. Such as, true up on our utility bill, monitoring and maintenance. That being said we would choose Green Air again.

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.

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 trouble shoot the system within a day of response. After inspection replacement parts were identified/needed, so Nick informed us he would contact Lennox order the parts and be back out. We knew since it was during holidays there might be a delay, but we were up and running the minute Nick received the parts. Fast Response time, Easy Communication, excellent customer service.

We are very pleased with the professionalism and great service that Green Air has provided. Nick Donzelli designed an excellent HVAC system for us when we renovated our home in 2016. The system is completely quiet and efficient. We are always very comfortable in the cold of winter and the heat of summer. Our energy bill is low and consistent throughout the the year. His company responded immediately and assisted us when we needed to do additional work on our foundation that required our unit to be temporarily disconnected. Working with Aziz, who oversaw the installation and conducted maintenance on our unit, is very pleasant to work with. We would definitely hire this company again if we were to do another renovation or build a new home.Sincerely,Burt and Molly Weinstein

When you find a company that is there for you, a company that is dependable and goes more than the extra mile to keep its customers happy, that is one you want to hold on to; one that you hope will be there for the long run. Green Air is just such a company. Owner Nick Donzelli is just outstanding. I trust him without reservation. His employees are very skilled and fun to be around, a perfect match. They take time to explain items I have questions and concerns about. The office staff - Marquisha in particular is a pleasure to work with; very prompt in getting to me items I need to be aware of to complete a job efficiently. I am extremely satisfied with the HVAC and solar projects they have done for me - and I look forward to working with them again in the future.

The Green Air guys were amazing. Did an HVAC overhaul and installed a new Solar setup. They were professional and on top of everything, from drafting plans to permitting. After given the runaround by the national guys (Sunrun, Sunpower, etc) I'm so glad I went local and with these guys. Would definitely recommend.Services: HVAC system maintenance, Roof installation

Green Air installed and has serviced the AC units in our home, They are very reliable and very knowledgeable. They promptly return phone calls and there receptionist is so courteous. They provided me with a clear cost breakdown. And the installation staff are very friendly and very competent. They are willing to schedule to meet our needs. In short, I highly recommend this company for your AC needs.

There are so many reasons why I will always go to Green Air for help and the first is Nick's high marks for being a professional who choses to do the very best he believes he can give. All of his team work together with the same high standards as Nick has created. They are all so dedicated in doing the best job for "Green Air". What Green Air has is professional people doing outstanding work. He's become a friend of my husband and myself because of all this good work they have achieved together.I thank you all for your dedication and caring about the work you perform!

Jayman came out for an HVAC quote, got ghosted afterwards. No calls, no emails, communication, nothing. Very unprofessional.In response to the owner's response, no such email was received at all. Given that you also have my phone number, the lack of follow-up is inexcusable.

My heater was beyond repair, the roof leaked & as I was getting older, summers seemed to be getting unbearably hot. My husband had passed away so any decision to make the needed repairs was completely up to me. And I was a nervous wreck about making such a big investment on my own. I’d had a couple of estimates that seemed really high and the people didn’t inspire my confidence. Then Nick Donzelli came out. I had a million questions & I know I must have been driving Nick crazy. But, he was very patient and always explained all my options and answere all of the many emails I sent him. I was concerned that with a new heater and AC unit that my PG&E bill would be outrageous. He then educated me about Solar & helped me find the appropriate financing I would need in order to add that to job.The jobs were done promptly and all his men were courteous, answered my questions, and cleaned up after every step of the job. Later, when a solar specialist came out to inspect the work, he was very complimentary of the job that Nick and his crew had done.I couldn’t be more pleased with the work Nick Donzelli and his company, Green Air, completed & would definitely recommend them to others.

We had Green Air put solar on our home and are very pleased with the outcome. They were efficient, polite, and patient with our questions and concerns. We wouldn’t hesitate to refer them or use them again in the future.

Showed up on time. Work was extremely professional. Installed 2 batteries and 26 panels. Now we get bills from PG&E showing a negative amount due. Nice to know we can run our AC in the summer without going broke.

Nick and the team did a large project at my house. About 75 panels, a heat pump for the pool, added heat pumps for my house and a large battery pack. Now, most major things in my house are run by the panels. They are thorough and efficient. I highly recommend them!

Nick and his staff always take great care of my clients and myself 4 air conditioning, furnace, solar needs. Nick is one of the smartest guys I know and always makes my clients feel comfortable with the job to be done with a great explanation of what the problem is and his solution but is competitive in his pricing as well.

Absolutely extravagant pricing. Contacted them for a tesla wall charger install. They quoted me 3K for the install. Let me check the spare pot of gold in my yard. Are you using diamond coated wires and coating my garage with diamonds too while you are doing this?

I am extremely happy with Green Air. Everything happened when I was told it would. I don't have a yard. It is all garden. I was extremely nervous about what would happen to my plants! I was so pleased, not a destroyed or damaged plant. The clean up was fantastic. New roof and solar, and everything was neat and clean when the job was done.
