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.

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.

Put in a large Solar system 4 years ago and it already paid for itself. Installing Powerwall Back up system as well and service has been outstanding even helping with other non-solar related HVAC issues!

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!

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.
