The signs of a failing furnace can be difficult to miss. You’ll probably notice if your heating system breaks down and stops working altogether in the middle of winter, but there are other signs that you may need our furnace repair services.
The signs that your heating system may need repairs include:
Heating bills that are higher than usual
Rooms in your house that heat unevenly
A lack of airflow through your vents
Strange sounds such as banging, grinding, or screeching coming from your furnace
A burning smell that doesn’t go away within an hour
As far as these signs go, the most common one is the strange smells coming from your furnace. A burning smell that goes away after about 20 minutes is normal if you haven’t turned on your furnace for several weeks.
This is merely dust on your HVAC components burning away. However, a burning plastic or rotten egg smell that doesn’t go away is a sign that your furnace has serious problems and is in dire need of repair.
You might also need more frequent furnace repairs if your heating system hasn’t had a tune-up in over a year or if your system is over 10 years old.
Most furnaces will last between 15 and 25 years, but they start to show their age after a decade. Older furnaces can still work just fine if they are well-maintained, but be on the lookout for signs of breakdown and wear and tear if your HVAC system is that old.
