To directly Purchase a AO Smith HVAC Motor:
Click Here
for our HVAC Motor Purchase Price Page (page loads slow due to volume of info, 1750+ motors)
We have placed the AO Smith HVAC Catalog online below so you can view detailed specifications regarding a specific HVAC motor in PDF format. This should aide in your quest for information.
You will need Adobe Acrobat to read these pages.
The software is free, download from if you do not already have it.
HVAC = Heating, Ventilation, Air Conditioning       OEM = Original Equipment Manufacture
  Click here for  Product Cross Reference (A Link to AO Smith's website) if the number crosses, be sure to click on the part number to  look at the motor picture and specifications in the AO Smith catalog to ensure the motor will work in your application. If your number does not cross reference, we have no way of knowing which motor you need. AO Smith manufactures a lot of their motors specifically for Original Equipment Manufacturers (OEM), which means there may be no off the shelf replacement available, meaning the motor will have to be purchased from the OEM or their distributors.
Tips for numbers: If the number looks something like "8-181792-02", only enter 181792 (the middle 6 numbers). Or "JE1M106N:, enter it with out the last alpha character, JE1M106.
If you need help send an email and we will try and help you. Please include as much information as possible

Note: AO Smith purchased Magnetek / Century electric motors. They are in the process of eliminating and consolidating the motor models. If the motor is out of stock we will locate, if possible, an equivalent motor and notify you of our recommendation, then you can make your decision on the purchase.
