Bought a goodman package unit heat pump 18 months ago. This winter its broken down several time s. Installer made several calls but cant seem to fix it. Called goodman for some technical help and was told that they only talke techs if i was a professional repairer. My repairer doesnt want to call them, says there is only 1 or 2 people to service the whole east coast. Beware buying goodman unless you want to be without heat a lot....
