    • Business in Review

      Tim Bartman and Eric Stackowicz, owners of the two local One Hour Heating & Air
      Conditioning ® Franchises, both joined the One Hour brand in 2004 after being in business for many years on their own. Once competitors, they now work as a team to better serve Washington County. Tim located in Monongahela, and Eric in Eighty Four both joined the franchise to offer more to their customers and employees and being around for the long haul is important to both. They've seen many of their competitors go out of business and consolidators buy out others. Neither wanted that to happen to them. They both felt it was the right move for everyone concerned. There are 3 other One Hour Franchises in the Pittsburgh area, and 260 throughout the country. One Hour is one of the fastest growing franchises in the country. The One Hour Code of Ethics is...

      1. Time... First and foremost we respect our customers' time. We are "Always On Time...Or You Don't Pay A Dime! ®". No questions asked.

We practice proper financial and accounting procedures in accordance with all laws governing a privately held business.

      4. Excellence... We design, install, service, and repair HVAC systems and parts in strict accordance with the highest industry standards.

      5. Safety & Reputation... We maintain a clean, safe, respectable and reputable place of business that reflects the high standards of the ONE HOUR brand.
