I used Opie's One Hour Heating and Air to do my fall tune-up. I have been with the company for a long time and I enjoy seeing the staff - they are great at what they do. I find them to be very professional, and quite friendly, too. I would keep using them in the future since I am happy with the work they have given me so far. I don't recommend anyone regardless of their work, but I do think that other customers will benefit from their service if they give them a chance.
