how long do furnaces last

Without a doubt, before buying any HVAC system, one of the most asked questions is about the furnace’s lifespan. The lifespan of a furnace typically ranges between 15 to 30 years. Several things can affect the life of a furnace and that’s what we’re discussing in this article.

Read along to understand those factors and also get a brief of the top brands in the market today.

Factors Influencing the Durability of Furnaces

The duration for which a new furnace effectively operates before calling for a replacement is important for ensuring that your home remains comfortable and energy-efficient. Many factors play into this longevity, helping homeowners navigate their heating system options with greater insight.

A furnace's enduring functionality starts with its initial setup. Ensuring it's installed by seasoned professionals, in line with the manufacturer’s guidelines and local regulations, guarantees optimal efficiency and longevity. Conversely, subpar installations can lead to inefficient airflow, unnecessary strain, and frequent cycling—issues that notably shorten a furnace's life expectancy.

Keeping an electric or gas furnace in top condition is key to extending its lifespan. Qualified professional inspections and tune-ups should be considered for annual maintenance, with tasks such as checking blower motors, testing airflow, and assessing thermostats being routine. Homeowners should be vigilant for any operational irregularities—like strange sounds or a drop in heating capability—which could indicate repair needs.

The build and brand of a furnace affect its durability. Gas furnaces often last longer and operate more efficiently than oil-based models. Moreover, high-efficiency furnace units with higher Annual Fuel Utilization Efficiency (AFUE) ratings utilize advanced technologies that minimize energy consumption and mechanical wear, enhancing longevity, and reducing repair costs and the need to replace a furnace.

The lifespan of a furnace is also dictated by its operational demands, largely influenced by the local climate. In colder areas, such as Ontario, furnaces undergo more intensive use, which can hasten deterioration. The size of the home and the furnace's capacity also affect its operational stress. An overburdened, undersized furnace for a large space is likely to degrade faster.

The setting in which a furnace operates significantly affects its longevity. Units in dusty or chemically active areas may degrade faster due to air quality issues that can clog an air filter and strain the system.

Technological advancements can make older furnace models seem outdated. Newer furnaces often come equipped with sophisticated sensors and control systems that optimize efficiency and minimize the risk of malfunctions, a proactive approach to extending a unit's life.

Efficient furnace operation requires proper ventilation and maintained ductwork. Compromised ducts can overwork the furnace, leading to increased energy use and quicker wear. Regular inspections and maintenance of ductwork are essential for preserving furnace efficiency and longevity.

The type and purity of fuel used to influence how cleanly a furnace operates, impacting its efficiency and lifespan. Gas furnaces, for example, need a consistent supply of clean gas to avoid operational inefficiencies and potential damages.

Top Performing Furnace Brands

Carrier, Trane, and Lennox are widely recognized as leaders in the furnace industry, notable for their advanced features, efficiency, and diverse offerings tailored to different home heating needs:

These brands are celebrated for their furnaces equipped with adaptive features such as variable speed fans and modulating burners. For instance, models like Trane's XC95m and Carrier's Infinity 98 excel in adjusting their output precisely to meet the heating demands of a home, enhancing both comfort and efficiency.

High-end models from Lennox and Carrier are engineered to operate quietly, which significantly enhances home comfort by reducing the ambient noise often associated with heating systems. Similarly, Trane furnaces are designed with noise reduction technologies, ensuring quiet operation.

Demonstrating confidence in their product durability, these brands offer substantial warranties. Trane, for example, provides lifetime limited warranties on heat exchangers and generous warranties on other parts, aligning with the offerings from Lennox and Carrier.

These furnaces are among the most energy-efficient on the market. Models like the Lennox SLP98 can achieve efficiencies up to 98%, with Trane and Carrier also providing highly efficient models that could help reduce energy bills.

The wide range of models from Carrier, Trane, and Lennox ensures there is a suitable option for various home sizes and configurations, accommodating both small and large spaces efficiently.

How to Enhance the Life of your Heating System?

Ensuring your furnace operates at peak efficiency while prolonging its life is crucial for both comfort and cost savings. Let’s explore practical tips endorsed by Comfort Union, a top provider of HVAC solutions.

What Are Customers Saying?

Check out some of our latest reviews.

When it’s time to choose or upgrade your furnace, selecting a high-efficiency model is key. These furnaces are not just good for your wallet due to lower energy bills; they also endure less strain because of their efficient fuel use. A model with a high Annual Fuel Utilization Efficiency (AFUE) rating is especially beneficial, as it delivers the same warmth with less effort, reducing wear and tear.

Adding a smart thermostat to your heating system is a brilliant move. Far from mere schedule keepers, these gadgets adjust heating based on your daily patterns, minimizing unnecessary operation. This not only keeps your space consistently comfortable but also eases the load on your furnace, helping it last longer.

The importance of indoor air quality can’t be overstated. Furnaces forced to push air through dirty, clogged filters have to work harder, which can lead to overheating and quick degradation. Changing filters regularly is a simple yet effective way to maintain system efficiency and reduce the replacement cost of your furnaces.

Comfort Union stresses the importance of routine expert maintenance. Their seasoned technicians can identify and address potential issues before they escalate, ensuring your current furnace operates optimally. Regular check-ups help maintain efficient operation, significantly extending the life of your unit and ensuring your home remains a haven of warmth.

I had an issue with my furnace, went to reset my main breaker to power cycle trying to troubleshoot it... Breaker crapped out so I was sitting on an electrical, and furnace problem.Gave these guys a call and they were able to come out within 2 hours. Required a full main breaker replacement, and new gas valve on my furnace. They diagnosed it in only a couple hours, and fixed everything the same day.Had a great experience, the technicians that showed up were professional, and very knowledgeable. I'll definitely be using these guys when I eventually have replace my aging furnace.

Had a bit of a crisis with rental property heating system in Calgary, our Goodman furnace gave out and had countless furnace repairs over the years. They got a new Carrier furnace installed quickly and very competitively priced compared to other carrier dealers. Wasn't expecting such quick service in the cold months. Definite recommend!
