Did not provide services described on the voucher. Paid $59 for cleaning of unlimited vents, system analysis and dryer vent cleaning. The company rescheduled several times, showed up almost 2 months later, came in unmarked vehicle with no industrial equipment, 2 employees (one wearing a cast), did the system analysis and did not clean. Only poorly cleaned 2 vents and told us that it would cost over $1400 to clean the remaining vents and add 2 uv lights for our dangerous mold. When we refused, the amount was dropped to $800. Tried contacting several times and never an answer. Paid less than $400 to Sears for same EXACT service and they advised that we did not have dangerous mold. SCAM!!!
