Your furnace is the central component in heating your home — so it can understandably be a little worrying if you start hearing it make unexpected noises.
There are a number of potential issues that you can consider when troubleshooting whether your heating system is operating properly, or if it’s time to bring in an HVAC technician to repair your furnace.
Here is a list of some common culprits:
- Loose Components
- Clogged Air Filters
- Issues with Duckwork or Obstructed Vents
- Blower Problems
Read on for a more detailed breakdown of each common issue!
Loose Components
A common culprit for banging noises is when a component in the system has become loose over years of operation. It could be the case that screws, panels or other pieces within the system have jostled free and are banging around as a result of the air moving through the system.
To troubleshoot this, simply open up the furnace cabinet and inspect the machinery for any sign of damage or loose parts. You may be able to solve this annoying issue with a screwdriver or by replacing a piece that has slipped out of position.
Clogged Air Filters
If you notice that your furnace is running louder while under normal operating conditions, it may be time to change the air filter. A clogged filter will put more strain on the system by restricting airflow, or it may also cause a whistling noise as air flows through.
To repair this, simply take note of what filter is being used in your system and purchase a replacement at your local home improvement store.
Issues with Ductwork or Obstructed Vents
The ductwork in a heating system is responsible for helping the air flow from the furnace around the home. Because of regular changes in temperature, especially as the furnace turns on and off, ductwork can expand and contract — creating various noises. This is not a cause for alarm, and will go away as temperatures stabilize.
Similar to the clogged air filters, another potential reason your furnace is operating louder is if vents around the home have been closed. This would mean that your system is struggling to produce heat, which isn’t getting out into the rooms. If your furnace is loud and if certain rooms in the house are colder than others, check to make sure the vents are unobstructed and open.
Blower Problems
Most furnace systems rely on a fan to blow hot air into the ductwork. If a fan has become misaligned or is beginning to show wear, it can make a squealing or grinding noise. This should be addressed, as over time the problem will get worse until the fan inevitably stops working.
In most cases, it’s best to rely on a professional HVAC technician to address any issues with fans or blowers, as it can be a complicated or costly procedure to manage as a DIY project.
