You cannot expect your current furnace to last forever. No matter how much you maintain and service your furnace, it will start facing irreparable damage once it crosses the 10-year mark. In such cases, furnace owners should know how long their furnaces can work efficiently and safely.

If you are tired of contacting your HVAC company for regular furnace repair in Flower Mound and want to buy a new system, you should know how long it can work.


If we talk about the number of working years of a furnace, it ranges from 10 to 40 years. However, most furnaces start losing their efficiency after ten years, so you will face lesser efficiency levels and higher energy bills if you force your system to work after ten years.

  • Gas furnaces are your best option if you want a heating system that will warm your place quickly and work for 15 to 20 years.
  • Electric furnaces are costlier to install and operate than gas furnaces, but they have a lifespan of 20 to 30 years, which compensates for the extra cost.
  • Oil furnaces last for 30 to 40 years due to the cast iron heat exchangers.

You can contact your HVAC contractor in Flower Mound, TX, to know more about the working of different types of models and which one would be suitable for your place.

Factors Affecting the Lifespan of a Furnace

As the furnace owner, you should know about the factors that can increase or decrease the lifespan of your furnace.

  • Maintenance Schedules

    Regular maintenance of your furnace ensures that its parts are working efficiently and the system is not facing any significant problems that can affect its working.

  • Quality

    Purchasing a furnace manufactured by a local company may help you save some money initially, but the system may stop working after a few years. Purchasing a qualified furnace helps in its lifespan.

  • Thermostat

    The thermostat controls the working of your furnace; setting your thermostat to the highest or the lowest temperature may damage the furnace and its components. However, setting it at the ideal temperature keeps the furnace working efficiently. Get your heating repair in Argyle at a great price.

  • Ductwork

    Unclogged and clean ductwork ensures that the warm air reaches all the parts of your home. Dirty ductwork or clogged ductwork will force the system to push the air into the rooms, leading to more wear and tear.

  • Size

    Purchasing the right furnace size for your home is essential for an efficient furnace. If the furnace is too small for your home, it will not warm up your place efficiently. If the furnace is too big for your home, it will frequently short-cycle and may break down.

  • Placement

    The area where you install your furnace should not have excessive moisture levels as it can corrode various parts of your furnace quicker than usual.
