The Story Behind Our Success

Chris Mahoney and Rocco Mirabile are the dynamic duo behind Pro-Tech HVAC Home. Combined, they carry nearly 30 years of HVAC service, design, and installation experience between them.  

Their journey began many years ago while on a factory tour of the American Standard/Trane plant in Tyler, TX. At the time, Chris was helping to grow a successful residential HVAC company and Rocco was at the helm of his own highly successful commercial HVAC company known as Pro-Tech. Both grew up in St. Mary’s County, MD and they quickly became fast friends…and it wasn’t long before they started drafting plans to combine forces. 

Rocco’s years of running a commercial business along with his unmatched technical expertise combined perfectly with Chris’s background in business, hospitality, and residential HVAC. The driving force behind the collaboration is their agreement that they can do things differently; by creating an environment where the GENUINE CARE and COMFORT of their customers is paramount.
