Left the place in worse condition than when they arrived. Needed to have an issue looked at, add says they inspect with camera ... they don't. I have no heat in one room, needed to know why. Sales lady was confident they would do that work. The service technician said they only clean the ducts, call an HVAC company. Now I have a loud buzzing from the cold air return that has something jammed in there that didn't use to be there. Called them to complain, they said they did what they were contracted to do. Now I have to go in and find out what really went wrong.
