nortek maytag, nutone, nordyne, gibson, broan, frigidaire, westinghouse manufactures defective heat pumps, expects others to pay for their mistakes, class action needed O'fallon Missouri

New NuTone/Nortek heat pump installed in 4/2015. Made loud "moosecall" noise periodically during heating ever since initial install. Cause of this trouble is likely a stuck reversing valve. While trouble shooting this, installer found another manufacturing defect that restricted refrigerant flow. So at least 2 defects in manufacture. Nortek left my installer completely on his own to repair their manufacturing defects - providing no assistance with either labor or part costs. Unsurprisingly, after fixing one of nortek's mistakes, installer refused to have anything more to do with it, leaving me with a still defective unit. Apparentlly Nortek feels entitled to manufacture junk without having to take any responsibility for themselves.
