This has got to be the worst company in the world. I called the number on their website, for a quote on ac flex duct, that was displayed on google, and their home page. Only to sit on hold for a long time, and then told the ducts are temporary, for tents only. Their home page states the following:"HVAC Insulated-Flex" Ducting. The “HVAC Insulated-Flex” hose is a superb choice for HVAC air duct use. " "These ducts for air conditioning are meant for residential and industrial air movement applications. It is a fairly adaptable hose that can function well in a variety of venues. "Completely and totally misleading, and unprofessional. If you do not have HVAC flex duct for residential construction. Please remove your false advertising from the internet. You are wasting a lot of people's time, and money, with your false advertising.
