Had Lorne from Vacworks come in for low suction issues in parts of the house, vacuum was working fine directly from the unit. After he flushed the CVAC and was getting ready to leave he mentioned the unit was overheating but would be fine in a couple of hours. When we tried a couple hours later the vacuum would turn off after a couple seconds. Over the phone he admitted that the flush ruined our motor which was working fine before he came over and he would charge us in full for labor to come back in fix it. I would not recommend them.
