We purchased a new home this summer and didn’t know the heat exchanger was gone. We were about to replace the furnace with another company because the labour was so expensive and the part was not available in Ontario. Not a happy moment! I finally found the sticker with Appleby Systems and contacted them. Ryan took the lead and managed to locate a part in Ontario and got us taken care of under the original warranty as the unit was only 6 years old. His actions had an impact and I will definitely continue to recommend him! Exceptional customer service!
