I am very satisfied with the service that Keith did for me. The service window was scheduled for between 11am and 1pm and he arrived at 11:30 . As far as I can tell he did an awesome job. My experience with Aire One goes back to 2006 when the furnace in my not yet two-year old home started to screech unbearably loud on a Saturday morning. Aire One was the only furnace supplier/repairservice to answer the phone. After talking to their rep, I drove to Kitchener to discuss my issue and options with him. He was very friendly, helpful and reassuring. He came on the Monday, provided me with options and a quote on a new, more efficient furnace with a ten year warranty. I opted for the new furnace and it was installed on the Friday. The warranty came in handy last summer when the motor in the furnace failed. A technician arrived promptly, identified the problem and was back in two days with the replacement. The cost of the part, service calls and the labour was all covered by the warranty. Aire One was there for me. I would not hesitate to recommend them to my friends and relatives, and I have done so.
