Contracting Ducts

If the noise isn’t coming directly from your furnace, the issue may be in your ducts. While your ductwork is constructed from rigid metal, the change in temperature and pressure when your furnace first turns on can cause this material to contract and expand.

This often happens when your vents or air filters are blocked or your ducts are too small for the amount of air being pumped into your home. Try cleaning your vents and replacing any dirty air filters. If this doesn’t help, it’s time to speak to a pro.

Delayed Ignition

If the banging noise is coming from your heater, it may be a delayed gas ignition. This is when the natural gas in the furnace collects for a few moments instead of igniting immediately. When it finally does spark into life, the gas that has accumulated in the furnace catches alight and causes a small explosion. In some cases, this can even damage your heater.

Delayed gas ignitions often occur when there is too much air mixed with your furnace’s natural gas. However, your burners may also be misaligned or dirty. In some cases, a weak pilot light can cause a delayed gas ignition, too.

At Gold Star Services, our pros will assess your combustion furnace, using the latest technology to diagnose and resolve issues in record time. More than 90% of calls are completed on the same visit.
