This has to be one of the worst HVAC products on the market, we have got burned twice by this company.
Lack of support, zero organization, no communication.
Plus the product is a waste of time and money.
We have now removed all the dampers on both jobs in homes we did installs on. Both clients were very upset with the product. We sent new and slightly used dampers back in a short time, I'm still waiting for over 6 months for a refund check that was sent out weeks ago, must be coming by pony express. Upper management, salespeople, and support are all the same unprofessional at best. Stay clear of this company and the products.
If I could give negative stars I would.
Bottom Line: No, I would not recommend this to a friend
