Dear Crystal, In a nutshell, the 5 year promise provides an option to buy a very heavily discounted replacement product for up to 5 years after the date of purchase. The full warranty applies for the standard warranty period. Between the period the warranty expires and 5 years from the date of purchase, a replacement may be purchased for 40% off the price listed at www.blastzonecommercial.com. The product will ship without the blower. The full warranty excludes issues such as mildew, user damage, etc, but the 5 Year Promise does not. You can read the full details of the 5 year promise here: https://www.blastzonecommercial.com/5-yr-commercial-promise Sincerely, Blast Zone Support
