If you’re a homeowner, one of the most important (yet often overlooked) aspects of maintaining your home is ensuring your furnace is in good working condition. After all, it’s what keeps you warm and cozy during those chilly months. But how long should you expect your furnace to last?
How Long Should a Furnace Last?
On average, a well-maintained furnace can last between 15 to 20 years. This lifespan can vary depending on several factors, including the type of furnace you have, how well it was installed, and how frequently it’s used.
The Importance of Proper Installation
Let’s start with installation. On the inside all furnaces work essentially the same, especially when you are comparing standard efficiencies and brands. In theory that means they should all last about the same number of years. However, installation plays a huge role in your furnace’s lifespan. An improperly installed furnace can lead to a range of issues, including poor heating performance, increased energy bills, and even safety hazards. That’s why it’s crucial to hire a qualified HVAC professional to handle the installation. They’ll ensure that your furnace is set up and sized correctly, which can significantly impact its longevity. An undersized furnace will work harder than it needs to, thus shortening its lifespan substantially.
Furnace Type
Electric furnaces can last longer than gas furnaces. On average an electric furnace lasts 20-30 years while gas furnaces typically last 15-20 years.
Climate and Usage
Another factor to consider is the climate in your area. If you live in a region with extreme temperatures, your furnace will be working harder and, consequently, may experience more wear and tear. It will have to work harder for longer periods, potentially reducing its lifespan.
The Role of Annual Maintenance
Regular maintenance is key to extending the life of your furnace. Just like a car needs regular oil changes, your furnace benefits from annual check-ups. During a maintenance visit, a technician will inspect and clean your furnace, check for any potential issues, and make necessary adjustments. This can help prevent unexpected breakdowns and ensure your furnace operates at peak efficiency.
Signs Your Furnace Might Need Replacing
So, how can you tell if your furnace is reaching the end of its life? Here are a few signs to watch for:
- Increased Energy Bills: If you notice a sudden spike in your heating bills, it could be a sign that your furnace is working harder than it should be.
- Frequent Repairs: If you find yourself calling the repair service more often, it might be more cost-effective to invest in a new furnace.
- Strange Noises: If your furnace is making lots of noises on start-up and continuously throughout operation it may indicate a larger issue
- Short Cycling: If your furnace is turning off and on frequently without ever reaching the set temperature it may indicate a larger issue as as well
- Uneven Heating: If some rooms are colder than others, your furnace might be struggling to maintain consistent temperatures.
- Old Age: If your furnace is approaching or exceeding 15 years of age, it might be time to start considering a replacement.
How to Find Out How Old Your Furnace Is
Determining the age of your furnace is relatively simple. If your furnace is newer, you may have the manufacturer date listed on the side. If it’s not there look for the manufacturer’s label on the front of the furnace or inside the removable door. This label typically includes the serial number. This will show the month and year of production in the first four digits. If you’re unsure how to decode it, you can always call the manufacturer or consult with a professional technician.
