Nordyne Westinghouse Gibson and many more owner hvac company st.loise mi.

we installed these units as we are a heating and air conditioning company . these units with copper evaperator coils on the furnace have a 95% leak failure in 2 years or less . company only wants to replace defective part with no labor allowance so cost is pushed on to owner of equipment. all i have seen is complaints by end user  what about us company owners that sold this very defective part .something needs to be done as some of these replacement coils or all so far that we have changed have failed again.  beware we are going through hell with this product and are not selling this brand anymore . we have units that have been in for 20 plus years with no leaks   stay away and we hope someone starts a class action and helps us installers to as this is a manufacture defect and we are loosing and sufering with this junk product .
