How To Tell If You Need a New Furnace

While routine maintenance and having your furnace inspected every year are essential to keep it running for as long as possible, it unfortunately won’t last forever. It’s inevitable that you will have to replace your furnace at some point. The average furnace replacement can cost about $4,000-$8,000 or more, so how do you know when it's time for yours to be replaced?

The good news is, you don’t have to go at it alone! The experts at Technical Hot & Cold are here to share some of the most common signs that you need to have a new furnace installed. Let's get right into it so you know what to look for!

Old Age

The average lifespan of a furnace is about 15-20 years. If yours is somewhere in that range or older, it might be time to consider getting a new one. Furnaces not only perform progressively worse as they age, but they can also get harder and more expensive to maintain as the necessary parts become hard to find. 

Very old furnaces can also be dangerous, putting you and your family at risk of fires, explosions, or carbon monoxide poisoning as the components responsible for preventing these hazards can begin to wear out and fail.


Dust, Soot, or Rust

Have you noticed an unusual amount of dust build-up around your vents? This could indicate that your furnace is unable to clean the air it’s warming and sending through the ductwork. Try changing your air filter first. If the problem persists, you might need to get a quote for a new furnace.

If you’re noticing soot or rust build-up around your vents, however, this could indicate a more serious issue like a carbon monoxide leak. You’ll want to contact us immediately if you believe this is the case.

Uneven Heating

If cold spots are popping up around your house, or whole rooms aren’t being heated at all, there’s likely a problem with your furnace. It can become difficult for the system to push warm air evenly throughout your home as it ages, which causes it to work longer and harder to keep up with your desired temperature. This in turn can lead to higher-than-normal energy costs per month, which we all want to avoid. Regular furnace maintenance can help you keep those energy costs down by ensuring your system is operating efficiently. 

Weird Noises & Smells

Your furnace will make some noise when it’s running, but usually nothing louder than a dull hum. If you start to hear booms, rattles, scraping, whistling, wheezing, squeals, or hissing, you could have a big, potentially dangerous problem brewing that might include needing a whole new furnace.

The same goes for weird smells coming through your vents. The air produced by your furnace should smell “clean”. If it smells like rotten eggs or pickles, however, you could have a gas leak and should call the professionals at THC immediately – we want to keep your home and family safe and warm.
