The one I talked to today said no..
Ok, thanks for the reminder, the contractor I spoke with today said they do not charge extra, but asked that we be reasonible.. I can understand that..
Actually, I purchased my first home in 1976, second one in 81, the next one in 87 and then the last one in 91, (custom built the last 2) Honestly, I don't rember once where we had any problems at all, so either Im just lucky or the systems were installed right and I choose the right contractor. It would be intersting to see the statistics on the units today.. are they that questionable that people really should buy the extended warranties?
