Shawn Goerndt, The furnace has been working fine the last two nights since you came to do repairs to one of our units. Kudos to you! U DA CLEANER! U DA CLOSER! U DA MAN!!!! Shawn did an Outstanding job with results that met all my expectations!!! Shawn was professional, courteous, knowledgeable and focused. As a result of Shawn's outstanding work, I now know I made the right choice choosing Champion AC from a sea of other AC competitors. I'll be sure and ask for Shawn this coming Spring 2015 for the AC tune up. Thank you!.
