Which Furnaces Last The Longest?

Are you searching for a reliable and efficient furnace that will last you through the coming cold season and beyond? You’ve come to the right place! Navigating choices in furnaces can be tricky, but with a little research, it’s possible to find the one that best meets your comfort needs and budget.

In this blog post, we’ll look at which furnaces last the longest so you can make an informed decision when purchasing your new heating system.

Factors Affecting Furnace Longevity

One of the essential things to consider when purchasing a furnace is how long it will last. To determine the longevity of a furnace, you have to consider several factors, such as brand reputation, maintenance, installation, and usage.

Brand

Brand reputation is a significant factor that affects the lifespan of a furnace. Brands that have established themselves as reputable and have been in the industry for a long time will likely produce top-quality furnaces that last long. Brands that cut corners and produce low-quality products often have furnaces that break down and require expensive repairs or replacement shortly after installation.

A furnace built well doesn’t need much maintenance and can last for decades. When shopping for a furnace, it’s important to research and check out different brands’ reputations. You can read reviews, ask for recommendations from people who have purchased certain brands, and check the warranties offered by the manufacturer. Buying from a reputable brand may mean spending more initially, but the long-term savings are worth it.

Maintenance

Maintenance is another crucial factor that determines how long your furnace lasts. Proper maintenance and regular cleaning can significantly elongate a furnace’s lifespan. Failing to maintain your furnace leads to wear and tear that can result in expensive repairs or premature replacement. Some essential areas that require regular maintenance include the filter, blower motor, and heat exchanger.

Cleaning or replacing the filter every 1-3 months is necessary to keep your furnace running efficiently. The blower motor should be lubricated annually, and the heat exchanger should be cleaned annually. Scheduling yearly inspections and maintenance services from a reputable HVAC contractor can keep your furnace running for years and identify minor issues before they become major problems.

Installation

The installation of a furnace also plays a vital role in its lifespan. If a furnace is not installed correctly, it can cause many problems that shorten its lifespan. For example, if the furnace is not installed on a level surface, the unit may vibrate excessively, leading to wear and tear that causes damage to the furnace’s components.

Thus, it’s essential to have the furnace installed by a licensed and experienced HVAC contractor. They will ensure the furnace is installed correctly and all components are aligned and connected. A professional installer can also ensure the ductwork is correctly installed and configured to maximize the furnace’s performance and longevity.

Usage

Usage is another factor that determines the lifespan of a furnace. Overuse or misuse of a furnace is likely to shorten its lifespan significantly. A furnace used frequently to heat a large space or household is more susceptible to wear and tear than one used less frequently.

One way to extend the lifespan of your furnace is to use it optimally. For example, if you’re frequently away from home, consider setting back the thermostat to reduce the workload on the furnace. This strategy can also help to save energy and lower your utility bills.

Lifespans of Different Furnaces

Different types of furnaces have varying lifespans, and it’s essential to know the average lifespan of the different systems to make an informed decision about which furnace to purchase.

Gas Furnaces

Gas furnaces are the most common type of furnace used in Canada. On average, the lifespan of a gas furnace ranges from 15 to 20 years. However, this lifespan depends on several factors, including the brand, usage, maintenance, and installation.

High-quality gas furnaces from reputable brands can last up to 30 years with proper maintenance. Regular maintenance activities such as filter cleaning and lubrication of moving parts can also help extend the lifespan of a gas furnace. Problems such as clogged filters can cause the furnace to overwork and wear out, leading to premature replacement.

Oil Furnaces

Oil furnaces have an average lifespan of 15 to 25 years. Like gas furnaces, a furnace’s lifespan depends on different factors, such as the quality of the furnace, maintenance, usage, and proper installation. Regular maintenance activities such as filter cleaning, inspection, and heat exchanger cleaning can significantly improve an oil furnace’s longevity.

One significant factor affecting an oil furnace’s lifespan is the availability of oil in the region. If oil is scarce in a particular region, running an oil furnace can be prohibitive, leading to neglect of essential maintenance activities and premature replacement.

Electric Furnaces

Electric furnaces are relatively less popular when compared with gas and oil furnaces, yet they offer many benefits. For instance, electric furnaces are environmentally friendly, have zero carbon emissions, and operate quietly. The average lifespan of an electric furnace ranges from 15 to 20 years or more, depending on the quality of the furnace, usage, and maintenance.

Electric furnaces require much less maintenance than gas and oil and are not susceptible to the same issues with internal parts. However, homeowners who use electric furnaces usually report higher energy bills than homeowners who use gas furnaces. Electric furnaces remain an excellent option for homeowners who prefer a cost-effective, low-maintenance heating solution.

Propane Furnaces

Propane furnaces are a type of gas furnace that burns propane gas. Propane furnaces are relatively more expensive than natural gas and electric furnaces, but they offer excellent heating benefits. Propane furnaces generally have a lifespan of 20 to 30 years, depending on usage and maintenance.

One benefit of propane furnaces is that they provide more heat output than natural gas furnaces. Additionally, propane furnaces do not require electricity to operate, making them an excellent option for those who live in areas with frequent power outages. Regular maintenance is crucial in prolonging a propane furnace’s lifespan, and homeowners must have the furnace inspected and serviced every year before the heating season.

Conclusion

In conclusion, furnace lifespans vary by type: gas furnaces last 15-20 years, oil furnaces 15-25 years, electric furnaces 15-20 years or more, and propane furnaces up to 30 years. Each type has distinct advantages and disadvantages, so selecting one that meets your specific needs is crucial.

Proper maintenance, choosing a reputable brand, considering the fuel source, and ensuring proper installation are key to maximizing furnace efficiency and longevity. By following these guidelines, homeowners can extend their furnace’s life, avoid costly errors, and maintain warmth and comfort during cold months.
