How Long Does a Furnace Last?

How Long Does a Furnace Last?

Average Lifespan of a Furnace

The lifespan of your furnace is approximate, but it will differ in many instances. Furnace lifespan depends on the brand of the furnace, location in which they are being used, how often they are used, and more. Furnace lifespan ranges from 10 to 25 years.

What Makes a Furnace Work

When you turn on the thermostat and the furnace turns on, it is because of a series of components that work together. These include:
 - Furnace blower
 - Furnace ignitor
 - Furnace flame sensor
 - Furnace limit switch
 - Furnace pressure switch Furnaces may also have

Which Factors Influence Durability of the Furnace

The first thing to consider is what you are using your furnace for. Furnace lifespan will increase with outdoor temperatures, as it can be difficult on the machine. 
Furnaces may last longer in areas of Canada that have fluctuating temperatures throughout the year, but they might only last 4 or 5 years if used somewhere with warmer weather all year round. 
Furnace lifespan also depends on location. Furnaces used in basements will last less than furnaces that are placed outside. 

Furnace lifespan is affected by the installation technique as well; if an improper technique was used to install it, this could reduce the life expectancy of your furnace.

Signs Your Furnace Needs a Replacement

There are a number of signs that can indicate that you need to replace your furnace. Furnaces are not built to last forever, so if the one you have is more than 10 years old, it's probably time for furnace replacement. 

Furnace parts wear down over time and eventually stop working when the warranty expires. Furnace parts also wear down due to lack of maintenance or use. Furnaces may also start leaking oil, which is an indication that the unit needs to be replaced. 

Furnaces may also emit strange smells such as gas or burning rubber when they need to be replaced. Another possible sign that your furnace needs replacing is when it starts to break down and run irregularly or in spurts."

How to Extend Furnace Lifespan

To extend your furnace lifespan, you should perform regular maintenance on it, like changing the air filter and making sure that any hoses are properly attached. Furnaces can also be damaged if they're exposed to extreme cold or hot temperatures.

Furnaces need to maintain a minimum distance from walls, especially if it's an older furnace with radiators. If you notice strange, uneven airflow coming from your vents, this could also mean that your furnace needs replacing.

FAQ

  • Most common Boiler Issues

    - Boiler fails to ignite
    - Low pressure
    - Strange Noises
    - Boiler is not responding to the thermostat
    - Cold Radiators
    - Boiler leaking or dripping
    - Boiler cycling very fast
    - Available Hot water but No Heat

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • Why is there ice building up on the copper pipes?

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • Furnace is blowing cold air in Winter?

    This can be due to Ignition lockout, sometimes could be resolved by resetting the power  and if this does not resolve the issue you should contact a certified gas technician from A-Plus Quality to get this problem resolved!
