When we purchased our home, we realized that ourswas an older furnace (1992 model). It seemed to function ok, but we had never had a home with a gas furnace before, and I didn't understand what had to be done to maintain it, other than periodically changing the filters.
Knowing that the furnace (its an old Keeprite) may eventually need some repairs and not wanting to totally replace it, I believed the furnace protection plan was the way to go. I was right. After our first inspection it was determined that a bearing in the ventor motor was badly worn and warranted replacement. I was told that this was an expensive part (approx.) $400. and it would be fully covered by the protection plan.
To make a long story short, making that small monthly payment for the protection plan has paid for itself in short time when expensive components have to be replaced on an older unit such as ours.
During our annual inspection (free of charge) the furnace is tested for efficiency and safety as this is a natural gas burning device. It is nice to know that is within limits for safety and performance.
