Very Professional, Honest company that is not trying to rip you off which is rare in the Bay Area. They installed a brand new A/C unit to our house. Highly recommend for any heating or a/c project. Great work!

Giovanni is an awesome HVAC professional and all around good dude. He came over and gave me a better sense of my heating and duct situation to where I now feel more confident in getting this project completed. He's honest, friendly & knowledgeable -- all the qualities of someone I'd care to do business with again. Cheers!

I am really surprised that there are only 13 reviews for these guys. When i first found them through a different service(thumbtack) i looked them up in yelp and saw there were only 9 reviews. I was initially skeptical but looking at the available reviews decided on atleast getting an estimate. Now looking back its was very good decision. Giovanni and Kow were really professional and gave me couple of options to think over. Got a very good explanation of all the options and pros and cons of each approach. Learnt a lot and was more prepared for the other estimates!. As recommended by everybody i got couple of estimates from other contractors too. The estimate from Giovanni and Kow was the best that met my requirements. I personally like the fact that these guys don't change the estimate no matter what the real work surprises would be. And in my case i had a few. Giovanni and Armando were good sport and found a way to solve all the issues that came up. Not sure others would have the patience to fix the issues with the flue or the accessibility issues with the crawl space etc. The post installation cleanup was great, the holes in the wall(Electrical wires etc) were patched up really good, all the tubes and wires were covered really good. 10 stars for workmanship! These guys know what they are doing. I would and already have recommended them to my friends. Thanks guys for a very good experience. Good Luck.

Giovanni and his co-worker came to do an onsite quote for a mini-split ductless AC unit. They were both extremely professional and spent quality time answering my questions. I've had 4 quotes done prior to them, and these two guys blew me away with knowledge. The other HVAC contractors left out lots of details on the installation which I felt was vital to my project. Currently I'm waiting on my HOA for approval, but I felt that they provided such great service, I had to write a review ASAP. Additionally in regard to response time to Thumbtack, Giovanni was great. Very friendly and professional communication. I hope my HOA gives me the thumbs up for my install because I'd love to do the install with this honest company.
