Before and After a PM.

Quality Service Company, LLC is a locally owned and operated HVAC company. Chris McDonald started Quality Service Company in 2003 after working with other local HVAC companies for around 10 years. In 2011, Chuck Polk joined in partnership with Chris. Chuck had been working in the HVAC industry for over two decades with local HVAC companies, then as a Trane employee, and then owning his own business. The two merged their companies together under the name, Quality Service Company, LLC.
