When the winter weather finally ends during spring is one of the best times to consider making a big change with your home’s central heating system. Most years you won’t need to make any major changes—as long as the furnace is receiving regular maintenance and hasn’t shown signs its losing efficiency/dropping in performance. (Always be on the look out for a spike in your heating costs as a sign the furnace may be aging rapidly.)
However, if your furnace has recently given you trouble, you may be thinking about putting in a new one. Or, you could choose to have repairs and keep the furnace running for a few years. When comparing the cost of repairs against the cost of replacement, there are a few things to keep in mind.
