It was very easy to install and the price was amazing! My local HVAC company wanted to charge me over $3,000 to replace this fan motor and actually tried to get me to buy a $12,000 unit that I don't need. I found out what they were doing, did a little research and found this X13 motor, bought it and it was very easy to install. The old motor shaft was a bit rusty and took a little effort to get out, but this new one went in like butter. Tired of companies that lie and deceive people just because of the unknown. I learned how my block works and after 1 day I felt comfortable taking on this project and also finally got to know and understand how my block works. Now I know how much these HVAC guys are robbing people out there. Unless my system has lost all of the coolant and needs topping up, I see no reason to go back to one of the garages.
