The employee was great, on time, professional, knowledgeable, however... After he left that afternoon the house began to warm pretty significantly. I inspected the vents that the faces were taken off and cleaned and on about half of the house the duct was off and completely loose blowing cold air into the floors, walls, and ceilings. I was able to reattach the ducts to the vents and vent covers. This was pretty minor of a problem and for the price you pay for what you get. If you want to save money on your duct cleaning use this company, just remember to go around and check that all the duct lines are attached to the vent covers before he leaves your house.
