If you’ve ever seen the movie “Home Alone,” recall the main character Kevin McCallister’s tumultuous relationship with the beat-up furnace in the basement. The knocking, pinging, groaning, ponging, and banging that the starring furnace made was enough to scare a young boy into running up the stairs at top speed. While your furnace is likely not calling out your name, it might be making unsettling noises. In most cases, all the furnace needs is a little TLC and deep cleaning, but sometimes it can be more serious. Find out why your furnace won’t stop making strange noises and who to call for furnace repair in Kitchener.
Think About When You Hear the Noises Most
The best way to determine what’s wrong with your furnace is to schedule a diagnostic inspection. Professional HVAC technicians will come to your home and complete a thorough checklist to assess the possible causes for the noises and any other issues that may require residential furnace repair.
However, if you’re on a waiting list or you haven’t made the call just yet, you might be able to determine the root of the problem by deciding when you hear the noises most. Pay close attention and try to determine during which window the furnace bangs, clangs, bings, or knocks: when it turns on or when it turns off.
When the Furnace Turns On
If the noises occur primarily when the furnace starts up and circulates air through the home, you might have dirty burners.
Burners Can Accumulate Dust and Carbon
Carbon builds up on burners from combustion as a simple byproduct of regular operation. When this happens, ignition is delayed, and gas builds up instead of immediately lighting the flame for the furnace. After some time, the gas will ignite, creating a small explosion in your furnace. If not corrected immediately, dirty burners can lead to furnace replacement and fire hazards.
When the Furnace Turns Off
If the noises are noticeable when the furnace shuts off and the airflow stops, either the ductwork in the home or your furnace filter could be dirty, or both.
The Furnace Might Have a Dirty Filter
One of the least congratulated parts of adulting is remembering to change your furnace filter as directed. Depending on what kind of filter you have, it typically needs to be swapped out for a new one no more than every three months. Build-up can prevent airflow and causes your ducts to expand and contract, making popping noises.
The Ductwork Could Be Dirty
Even new homes can have debris or dirt in the ducts. During construction, errors could have been made, or even prior homeowners did not have ductwork vented correctly during a remodel. To ensure that dirty or blocked ducts are not the problem, a technician might recommend duct cleaning to prevent the popping noises from the expanding and contracting of metal when airflow is blocked.
Think About When You Didn’t Hear the Noises
While it is typically your responsibility to change your furnace filter regularly, the internal parts of your furnace should only be cleaned by HVAC professionals. With regular maintenance and cleaning, the noises that keep you up at night should subside.
Just because there are dirty parts in your furnace doesn’t mean that you don’t keep a clean house. Furnaces naturally gather dust and carbon buildup as part of the regular operation. A diagnostic evaluation of your furnace will identify the noise source and provide you with options to remedy it. Services range from cleaning and lubing to residential and commercial furnace repair and replacement.
