Thomas was very professional and super helpful with the inspection of our furnace today. Didn't try to sell us any unnecessary products or services, just told me the facts.

Ask for Diego - he was prompt and informative! Great technician and highly recommend.

Thanks to Diego for checking all our HVAC appliances today and spending the time to show me exactly why he recommended replacing a part, when he thought our next service would be needed, as well as general landscape of appliances being sold now and in the future. I feel confident in our expected costs over the next few years!

First experience with Green Air and couldn't be happier. Thomas (HAVC tech) arrived on time and was very approachable. He thoroughly explained my HVAC systems current state and his recommendations on keeping it running at peak performance. Monique in the scheduling office is also super kind and easy to work with.

Thankful that Green Air was able to pick up my maintenance after being a long time customer of Certified.

Look for Thomas. he's awesome. Arrived, identified the issue, (and my favorite) showed me what he was testing/doing. and resolved my issue. Putting this company on speed dial.

I used a local service company for a furnace problem, and after 6 weeks & $3000, they could not fix it and wanted another $5000 for a new 2 stage heater (much lower capability than my system). I decided to contact Green Air who originally installed my furnace, and they sent Ben (service tech) who was able to troubleshoot the problem and have it up & running in 20 minutes. I was even able to get $1500 from the other company as the original blower was never the problem. Appreciate the great support from Ben and Bryan to troubleshoot the problem and save me from a major investment that was not needed. Thank you!

DO NOT USE!!! This company is the worst i have done business with in years. they installed two all heater in two year and have been to my house about 20 times. they don't call , they don't fix things, they only make things worse and the refuse to repair the messes they create. it is terrible. now i have a very dangerous situation with my heater and they refuse to do a thing.

I chose Green air and Solar to do a solar install. Nick, the owner, is very attentive until you sign the contract, and then he's MIA. I've had nothing but problems from the install date to the billing. Instead of communication, there is just blame at the client. I would not recommend this company.

DO NOT USE. As I write this review, my house has no power despite no PG&E outage, and $50k worth of solar panels and powerwalls that are not working and are somehow also keeping my house off the PG&E grid. I am a member of their ""membership maintenance"" club and I cannot reach them. They have no working phones on the weekend. This is beyond outrageous. I paid $40k in CASH for 3 powerwalls that are at capacity but aren't working and the company provides no emergency contact. Screw you Nick. Reporting them to BBB
