My Trane blower motor was running whenever it wanted so I had it professionally replaced. As the tech was leaving he told me he "adjusted the motor size to a larger one" so it would run stronger. I noticed the system does blow a heavier volume of air now but it is also noisier. What is the point of doing this and what are the ramifications (speed wise, efficiency, and cost wise)? Also, How do I return it to its previous setting?
Thanks
