i purchased a prepaid service through one of those online discount coupon deals. when the tech came out from the Affordable Air Duct Cleaners, he told me i had more intake/returns then what the coupon allowed and his boss said he would have to charge an additional $150. i said just do what the coupon allowed for and was then told they could not do "partial jobs". if i had paid the additional $150 in addition to what the "coupon" cost me originally, i would have been over paying for this type of service in my area as compared to what my neighbors have paid for in the past with similar houses. this is a classic case of bait and switch- very shady business practices- i would never trust them let.
