This is the first really hot weather we have had since my Infinity system was installed and I noticed that the system seems to be reading the outside temperature too high. I can't seem to get 2 thermometers to agree, but by any measure the Infinity reading is 7 degrees too high - perhaps 12 degrees too high. What effect does that have on my system operation? I guess I should call for service and have this checked anyway, but is this something that should be done ASAP or doesn’t it really matter that much?
While I am calling them, I haven't been asked to buy an extended warranty - can it be bought after the install? If so, how long might I have to get it? I'd rather put it off as long as I can, but I'll ask them about it now if it matters.
