Why Do My Air Ducts Pop Every Time My Furnace Turns On?

If you have something weird going on with your HVAC system, turning to your local residential services experts is a great place to start. There’s no reason to wonder and worry, when you can get the answers and help you need. In the case of popping ducts that happen when the furnace turns on, our team at Brummitt Heating and Cooling is here to put your mind at ease. Fortunately, popping in your ducts is typically not a major issue, but it is still important to get an expert inspection to rule out any potential problems that could be dangerous.

What Does Popping in My Ducts Mean?

If you have recently had your ducts cleaned and you hear popping, the sound may be the re-pressurization of your pipes. The pressure causes the metal to expand and pop. This is harmless, but replacing your old ducts with circular or square options can help. Increasing the density of the metal used for your ducts can also alleviate the popping. Unfortunately, if an overhaul is not in the budget, you may just have to deal with the sound.

If your ducts are popping and it is not the result of pressurization, there may be a problem. You might have clogged or rusty furnace burners and that can lead to delayed ignition. Worst case scenario, this can lead to small explosions in your pipes, and obviously this is a dangerous fire hazard. It can also cause your exchanger to crack, which is a more expensive repair.

Who Do I Call If I Am Concerned about the Popping Sound?

Due to the potential hazard posed by the delayed ignition of your burners, you should call a professional right away. At Brummitt Heating and Cooling, we have 24-hour service available. We can investigate the popping sound and clean or repair any burners that are not igniting properly.
