When winter rolls around, the last thing you want is for your furnace to fail in the middle of a cold snap. A working furnace is crucial to keeping your home comfortable during the colder months. Still, like all appliances, it doesn't last forever. Every furnace will need to be replaced at some point, but how do you know when it's time? Our experts at Air Knights explore the factors determining when to replace your furnace and how to extend its lifespan with regular maintenance.
One of the most significant indicators of your furnace needing replacing is its age. A furnace lasts 15 to 20 years, depending on the type, model, and maintenance history. After 15 years, furnaces become less efficient and more prone to breakdowns. If your furnace is nearing or has surpassed the 20-year mark, it might be time to consider a replacement, especially if you've experienced frequent repairs in the last few years.
If you've been calling for furnace repairs regularly, it could be a sign that your system is reaching the end of its life. A furnace that constantly needs fixing, even minor repairs, will eventually cost you more than replacing it. Additionally, older models often use no longer available parts, making repairs more difficult and expensive.
When a furnace breaks down multiple times within a short period, it often signals that the system is struggling to function properly. If these breakdowns are frequent, it's worth consulting a professional to see if replacing your furnace would be more cost-effective than continued repairs.
As furnaces age, their efficiency tends to decrease. Older models, especially those 15 years old or older, often have lower energy efficiency ratings than newer models. If you notice a significant increase in your heating bills despite consistent use of your furnace, it could mean that your furnace is working harder than necessary to heat your home, indicating it's no longer functioning efficiently.
Modern furnaces are equipped with advanced technologies and are built with higher energy efficiency standards in mind. Replacing your old furnace with a more energy-efficient model could lower monthly heating costs, saving you money in the long run.
Another common issue with aging furnaces is inconsistent heating. If some rooms in your home are warmer than others, or if the stove doesn't maintain a steady temperature, it might be a sign that the system is no longer functioning correctly. This could be due to worn-out parts, a failing blower, or problems with the heat exchanger. If you're experiencing uneven heating, it's a good idea to have a professional inspection to determine whether your furnace can be repaired or if it's time for a replacement.
Furnaces are generally quiet when operating correctly. If you start hearing odd noises like rattling, squealing, or banging, it could be a sign of an underlying problem. While some furnace noises can be fixed with simple repairs, persistent or worsening sounds often indicate that the furnace is no longer working as efficiently as it should. If your furnace has started making strange noises, especially after it has reached the 15- to 20-year mark, it may be time to start considering a replacement.
A furnace that's not working well can affect your indoor air quality. If you notice that your home is unusually dusty or the air feels drier than usual, it could be because the furnace is not circulating air properly or is pushing air that is too dry. An inefficient furnace may fail to filter out dust and allergens, which can exacerbate respiratory issues or cause discomfort.
A new furnace can help improve the air quality in your home, as modern models often come with better filtration systems that help remove dust, pollen, and other allergens. They also typically maintain optimal humidity levels for improved comfort.
A severe issue that could indicate it's time to replace your furnace is the presence of carbon monoxide leaks. Furnaces that are aging or have a broken heat exchanger may leak carbon monoxide, a colorless and odorless gas that can be deadly. If you suspect carbon monoxide issues, it's essential to turn off your furnace immediately and contact a professional. Replacement is often the safest option if your furnace is old or has a history of carbon monoxide leaks.
Knowing when to replace your furnace can be difficult, but there are clear signs to look out for. If your furnace is over 15 years old, frequently needs repairs, has increased energy bills, or is no longer heating your home efficiently, it may be time for an upgrade. Replacing your furnace can provide several benefits, including lower energy bills, better air quality, and improved comfort throughout your home.
