Gas Furnace Replacement in Palos Heights, IL, 60463

“We've had Doornbos service our 2 furnaces for many years so when it came time for new furnaces Doornbos was our choice. From the initial call for the estimate to the installation of both furnaces and air conditioners the staff were professional and answered my questions. Phone Representative was courteous and helpful, salesperson was very knowledgeable and communicated what was needed and how much it would cost, as well as providing information about rebates. The Installation team were professional, cleaned up and went over the new products. As a prior customer with the two year service program, I am very satisfied with the company. My furnaces were 19 & 20 years old and I'm sure that's because of the regular service that Doornbos provides. Reasons for using Doornbos include, the Doornbos Reputation, Quality products, and the informative salesperson.”
