It would be great if the technician came with all necessary parts to do service like filters, etc. Numerous times I have been told that they only have one filter and will have to come back. No big deal, but would be better if they come prepared. Also related is that they should be able to know what kind of maintenance you have on your units when they show up. On several occasions I have been asked to make a decision on whether to fix something because they did not know I had a 10 Year warranty on parts and labor. Just those little things would make it "excellent" service. All in all, the technicians are very nice and I will continue to use One Hour.
