Recently I had Fanhandler module and Baldor industrial motor installed in my home. When I was told about how it would change the way my home would feel I must say I did not overly believe. Well I was wrong, the temperature through out my home is even, some bedrooms where always few degrees different and now they feel like the rest of the house. The quality of that motor sounds and feels like a higher grade motor. I really do not know why the furnace manufacture does not install this quality from the beginning?? I run this system with an air cleaner and UV light and we have 2 cats and big Doberman and my house smells fresh and clean. I just really want to thank you for helping me with this. This upgrade was worth every penny!!!!!!.
