Your air ducts are metal. This means that when they\u2019re hit with a hot or cold temperature, they\u2019re going to expand or contract a little. If you\u2019re firing up your heater after a long hiatus, then you might hear a little popping. This is normal.<\/p>\n<p>The popping becomes a problem when it\u2019s too loud or persistent. Then, this might be another issue going on with your furnace.<\/p>\n<h3>Check for A Dirty Air Filter<\/h3>\n<p>Is your home\u2019s air filter clean? You should be replacing your heater&#8217;s filter at least once a season. In practice, this is going to look like a switch out in the fall and in the winter. Your air filter is what keeps your heater running on high. If it\u2019s dirty, you might notice a change in the way that your home\u2019s heater runs and hear some odd banging.<\/p>\n<h3>Check for Undersized Ducts<\/h3>\n<p>Sometimes, your home expands as time goes on. You add on, add new members to the family, or adopt new appliances. Sometimes, the people who built your home just weren\u2019t built for the job. Undersized ductwork makes your heater work so much harder to get warmth to your rooms. You\u2019re going to hear loud banging as a result of exertion.<\/p>\n<h3>Check for Delayed Gas Ignition<\/h3>\n<p>A delayed gas ignition happens when there is built-up combustion gas in your furnace&#8217;s chamber. Furnaces are built to prevent this from happening, but sometimes things can go wrong if your system has been neglected. What happens as a result of this is a loud bang when you try to run your heater.<\/p>\n<h2>How to Tell Which Problem You\u2019re Experiencing<\/h2>\n<p>Now, are you having trouble determining which problem you\u2019re experiencing? For starters, you should change your furnace filter for good measure. If that doesn\u2019t change anything for the better, then you should take some time to note when you hear banging, how often it is, and note any changes. If the problem is infrequent and not too loud then you\u2019re just experiencing your ducts expanding and contracting. If it\u2019s loud and alarming, you\u2019re probably experiencing delayed gas ignition. If it\u2019s pretty loud and fairly regular, it\u2019s probably undersized ducts.<\/p>\n<p>Ultimately, you need the expertise of a professional to <em>really<\/em> tell. That\u2019s where we come in.
