Rated 2 out of 5 by Trouble with evaporator coil I purchased a Lennox system for my house in 2007. Had no problems for the first three years. In 2010 the evaporator coil developed a leak and was replaced in March 2011. In September 2012 a leaked developed in that coil and was replaced. In Febuary 2013 a leak developed developed in that coil and was replaced. Now in February 2014 a leak developed in that coil and was replaced today. Could you shed some light on why the coils are only lasting around a year? February 4, 2014
