Has anyone had to replace the airconditioning coils? We are now on our second replacement in less than 3 yrs. I understand the copper coils do not last in this environment?? The first time they replaced them with copper coils and the unit was less than 1yr old and covered by warranty, this time we have to pay $400+ with Munn's and they are being replaced with another material and only the coils are covered not installation/service. I contacted Trane and they tell me we are responsible for paying Munn's even though the coils are covered by warranty..
