When the cold days finally get behind us and the warm mid-year winter settles in is a good time to think about how your home furnace performed. If you encountered no major troubles from your furnace over the winter, your house stayed comfortable, and the utility bills were steady, you’ve probably got a furnace in good shape for next winter.
But if you’re reading this, it’s probably because something wasn’t right with the furnace, or you suspect it’s getting too old to be reliable. Replacing a dying furnace during the middle of the year is good planning, since you’ll have an easy time scheduling the service and won’t have to worry about staying warm while the work is being done. But how can you know for certain it’s time for a replacement? A new furnace is a major investment, and you don’t want to do it years before you have to.
