Michael Blackwood went beyond our expectations in installing mini split system. He even modified our breaker panel to make sure that we have a dedicated circuit for our AC. He took away all the packaging from out AC unit. He even cleaned up our backyard. Many other HVAC guys came, and wanted to install their system. Michael, on the other hand never tried to sell his system. I would recommend Michael for any HVAC related project. Above all, he is trustworthy. He worked,, whle we were way, from our home.

Michael installed a mini split ac system in my home and I am very happy with the results. Everything functions exactly as it should and it looks great too. Before the mini split system I had an ugly old swamp cooler that he removed and now I can’t tell it was ever there. If you’re interested in upgrading your ac/heating to a mini split system, which I highly recommend, give cool mechanical systems a call.

This amazing tech Michael assessed our non working AC system on the hottest day of the year in an extremely hot attic. He wanted to ensure that we had cold air when he was done and he got it completed. He is so thorough in his explanations which we find refreshing. Thank you Michael!

Very responsive and thorough in their work. Mike was great at sending photos of the issues and the work that was done as we were away when our issue occurred.
