just had the Fan Handler installed on 10/26/2010. The contractor recommended that I use the "fan on" option, immediately I noticed the drastic reduction in sound as the fan now runs on a super low and quiet mode all the time. The first thing I have to get used to is the fan running all the time, not the sound or lack of it, just the idea. My contractor put on one of your motor's as well and assured me that there was no issue. Now I just had to wait for it to get cold, as luck would have it there was summer like weather for the past few days. The temperature went down today and I got a chance to see what the product will do. I no longer have to reach for the remote every time my furnace comes on, and I have turned the thermostat from 73 degrees to 71 degrees. The heat has come on for very short periods of time and he temp seems to be maintained. I don't want to get to excited as it is early in the process, but if this is any indication of what I can expect I truly sorry I didn't discover you a lot sooner. I have just retired from law enforcement after 36 ½ so I am home all day to monitor its performance. I will contact you again once the cold weather has set in to advise you of my progress.
