Signs To Know It's Time To Replace The Furnace

It’s not always easy to determine when to replace an old furnace unless your furnace breaks down completely. Some signs can help you determine if it is time to replace your furnace.

  • Your Furnace Is Getting Old

It is unlikely that your furnace will need to be replaced if it is less than ten years old. Your chances of your heating system failing begin to increase after about 15 years.

  • High Energy Bills

Are your heating bills higher than they were in previous years? That could indicate that your furnace is working harder to maintain the same temperature as it did years ago. If you reside in Edmonton or the surrounding area, contact Mobil Heating & Air Conditioning Inc for furnace replacement.

  • Furnace Repairs Are More Common

A home HVAC system should only need minor repairs from time to time. If your furnace is not getting repaired as often as it used to, you may need to replace it.

  • Frequent Thermostat Adjustment

Your furnace could be in trouble if you constantly fiddle with the thermostat; this indicates that your furnace can no longer heat at its current load.

  • Uneven Heating Or Cold Spots

If one room feels warm and the other feels cold, this could indicate that the furnace is nearing the end of its life.

  • Furnace Making Strange Sounds

If you hear strange sounds such as popping, squealing, or rattling from your furnace when you turn on the heat, contact our HVAC expert for an inspection.

  • Strange Odors From The Furnace

It is normal to smell some natural gas when the heating system is turned on for the first time in winter. However, it is more unusual to smell it continuously.

As furnaces age, there is a greater chance that heat exchangers will crack. That could lead to gas leaking or carbon monoxide. Without any delay, call a furnace technician.


While regular furnace maintenance and servicing will ensure that your furnace runs for as long as possible, it is time to consider replacing it when it shows signs of wear.
