Mark Grant, fomerly of Ace Heating and Cooling is now Owner of Mr Heat and Cool. Ace Heating and Cooling still has some pictures of mark Grant on their web site and they have his credentials of being President of the Michigan Chapter of ACCA still posted on their site. Other than attending some classes there is no one there at Ace Heating and Cooling who has been involved with ACCA, unless some one was hired after I left.
