<human>: I'm trying to figure out if I'm going to need a new furnace soon.
<bot>: The best way to determine if you're likely to need a new furnace soon is to check the age of your current unit and assess its performance. If it's older than 10 years or has been poorly maintained, it may be time for an upgrade. Additionally, if you notice any unusual noise coming from the furnace, this could indicate that it needs to be replaced.
