Signs Your Furnace Needs Repairs
It can be difficult to correctly identify when your furnace needs repairs. You might think it’s working properly, and then the next day you come home to a chilly house. Fortunately, there are signs you can watch out for that signal it’s time to call a furnace repair company. Some symptoms to be aware of include:
- SHORT CYCLING: Short cycling is when your furnace turns on and runs for less than 3 minutes before shutting off. If this happens, schedule an appointment with a furnace contractor, as it could indicate a malfunctioning heat exchanger or thermostat.
- IRREGULAR FLAMES: The flames in a functioning furnace should be in a somewhat even row. If the flames are uneven or if they lean toward the back of the furnace, you should call for an immediate service appointment. This could mean the burners are dirty, or it could potentially signal a dangerous issue – a cracked heat exchanger. If the heat exchanger is cracked, your household is at risk of carbon monoxide poisoning.
- UNUSUAL SOUNDS: You should contact a furnace repair company if you hear loud or unusual sounds coming from your furnace. This could signal an issue that needs to be repaired.
