The winter of 2015 is causing another issue. We are getting numerous phone calls of units with damage due to the ice dams falling off of the roofs. Most customers don’t know that these damages are covered under your homeowners insurance. What is interesting is that on the surface units don’t show major damage but have been for lack of better term “tweaked”. Most newer units are built with very small tolerances and any disturbance will cause the fan blades to rub. The manufacturers have asked us to try to determine if this is a manufacturing issue or damage from ice. The simplest way to determine is if it worked in the fall and it’s not working now it’s probably due to ice or snow and not covered under the manufactures warranties.
