Martha from Thunder Bay gives us her feedback on her experience with Reliance:

" My air conditioner wasn't cooling and I called late in the day to schedule a repair. The telephone receptionist was very helpful and polite. He apologized for not being able to have someone come that day, but scheduled an appointment for early the next morning. The repair man was prompt, polite and professional. He found the problem, checked a few other areas just to be thorough and was gone in under an hour. Excellent!!! When I called to schedule a repair appointment, I thought I would be waiting till the following week. I was very happy with the timeframe, the professionalism and the promptness. Thank you! "

Ray from Thunder Bay gives us his feedback on his experience with Reliance:

" I had Dave come to look over my AC/furnace as the air conditioner was not working at all. He came in, checked both furnace & air unit, and said that my furnace was in good shape and didn't need to be replaced. He looked over my AC unit & got it working. He told me that the AC had a soon-to-be out dated Freon and that I might consider a replacement got the AC in the future. I feel he did an amazing job at getting my system working and giving me the option with the AC. It was nice to not have a repairman be a salesman first. I thank him for his honesty. Other companies that were in did not compare to the service I got today! "
