September is the month when the air starts to cool here in Salt Lake City, and while you still may be running your air conditioner on a regular basis, it will soon be time for your heating system to take over. Now is the time to check for any problems that may have developed or become worse over the summer. Cracked heat exchangers, in particular, are serious problems that need to be replaced before you start to use your furnace this fall. Cracks usually form in older heat exchangers which have undergone a lot of wear and tear over the years, but any system may exhibit signs of stress. The sooner you address it, the better off you’ll be.
How Heat Exchangers Work
A heat exchanger is simply a piece of shaped metal, which transfers the heat created by the burners to the air that needs to be warmed. Exhaust gases as also safely vented into the proper pies with the heat exchanger, removing it from your home.
Problems with Cracks
When cracks occur, however, that process is short circuited. Not only will heat bleed out from the heat exchanger — severely reducing the effectiveness of the heater. More importantly, it can vent toxic gases into your home, creating an immediate health hazard to your family. Many models contain automatic shut-off systems that will turn the heater off the moment they detect the presence of harmful gases, but that still leaves you with the significant problem of addressing the cracks before you can run your heater. Unfortunately, in most cases, the heat exchanger will need to be replaced. Fortunately, spotting the issue now still gives you several weeks to plan for a replacement session before you have dire need of your furnace.
