Ac and heating repair service near Mason, OH

I can't say enough about the professional service every time I bring in one of my Mercedes. For both old & newer cars, diagnosing the problems, finding the parts and fixing everything to perfection, with personal attention, is a perfect combination. Ricky & his team run a great organization and I recommend them to everyone!

All Speed Innovations aka Sigma Six Engineering is ran by a wanna be engineer named Pat Smith. Pat uses customer cars as his personal cars while in for service. They charged me for a alignment and the alignment wasn't done. They also took it to a alignment shop without my permission. When they installed plastic TGV deletes they connected a ground wire to them. Pat couldn't figure out how to connect his laptop to my car and disable the TGVs, I did this myself after reading how to do it on the Internet. They also built a cage for a customer and ruined the customers car. Everyone should stay away from this shop or anything related to what Pat Smith does.

For over 25 years Rob and Chuck have taken care of my cars and with concern for my time and finances. Shirley Freeman
