Gas Furnace Installation in Orland Park, IL, 60462

“Nick and Andy installed our new Carrier furnace yesterday. They also hauled away our 44 year old original behemoth. As you may expect, the installation required a fair amount of modification of the ductwork. The new furnace looks and works great. Nick and Andy were professional, efficient, and friendly. They took great care in maintaining the condition of our home, and when finished, swept the entire work area clean. Our salesperson, Bob, was knowledgeable and genuine. He was essential in helping us make several important choices. My wife and I believe they all did a terrific job.” – Howard K.
