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

  • What are mini-split advantages?

    Just as the name implies, a “mini-split” system is a “split system” however available in smaller capacities, for single room to whole house conditioning. Mini-split systems may range from as small as 9,000 BTUh per hour, comparable to say, a small window AC unit, for individual room use, up to 4 and 5 ton capacities for “Room By Room” (also known as “Zoning”) and whole house conditioning. With near universal design, mini-splits are “heat pumps” which provide both heating and cooling for a home. Here are key advantages when compared to traditional split systems:

    Efficiency- Mini-splits are highly engineered systems which offer attractive operating efficiencies, in many instances, eligible for utility company rebates.
    Heat Pump- Most mini-split systems are heat pumps, providing year-round comfort.
    Solar friendly- Due to very low power requirements, mini-splits are an ideal complement to “Net Zero Energy” homes, or any home using renewable power.
    Carbon footprint- Mini-splits are 100% electric, with zero operating emissions of any type.
    Zoning- Most mini-split manufacturers offer systems capable of room-by-room “zoning”, to account for peak demands of a room based upon construction type, exposure orientation and usage.
    Variable capacity- Mini-splits are typically DC inverter driven. That is, a variable speed compressor which modulates in proportion to instantaneous demand. Most conventional split systems, by comparison, operate with an ON-OFF strategy. (Would you use an ON-OFF switch as the accelerator in your vehicle?)
    Location, Location, Location!- Mini-split outdoor units are compact; they can be located far away from noise-sensitive areas, such as bedrooms and home offices. Mini-split indoor units have the ability to be installed where conventional systems cannot.
    They’re perfect for additions and remodels where access to current HVAC system is difficult to access.
    Modern mini-split systems are remarkably quiet; in fact, many times their operation is unnoticed by the end user.

  • 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.  

  • 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 heat pump?

    Heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.
