Is It Time to Replace Your Furnace?

Is It Time to Replace Your Furnace?


No one likes replacing a major appliance, but when something like your furnace nears the end of its lifespan, you might not have a choice, as consistently freezing-cold temperatures in your home can lead to such as:


  • Harming older adults, children, the immunocompromised, and pets
  • Damaging some appliances or sensitive electronics
  • Causing respiratory problems
  • Making everyone more vulnerable to colds and the flu


Unfortunately, a furnace wearing out is an inevitability. The average life of a furnace is 15 to 30 years, but that range falls with poor maintenance and neglect. 


With that said, here are signs of furnace wear and tear in Columbus, OH, that you need to be on the lookout for:

1. High Power Bills

A furnace’s efficiency declines with age, and as it reaches its maximum life expectancy, it needs more energy to produce the same amount of heat, which impacts your power bill.

2. Repairs Are Frequent

If you just fixed your furnace last month and it still has trouble heating your home, it’s likely on its last legs. A new furnace may be expensive, but keeping an old one running via constant repairs will run up a bill that could be much worse.

3. FurnaceIs Making Strange Sounds

Listen for new noises from your furnace, which can indicate major problems. Popping, rattling, booming, clicking, humming, and screeching are all sounds you may hear that you shouldn’t hear.

4. The Heat Is Uneven Across the House

If one room is cold and another is warm, or if you experience cold and warm spots within a single room, your furnace is on its way out.

5. Your Furnace Has Never Kept Up

You might not have an aging furnace, but in fact, one that’s the wrong size for your home! If it’s too small, it will never produce enough heat, no matter how long it runs.

6. Your Air Quality Is Poor

Of all the signs of furnace wear and tear in Columbus, OH, that can be a serious threat to your health, this may be the most significant.


When your furnace approaches the end of its lifespan, you may notice more dust and even soot buildup around your home. The extra particles in the air can aggravate allergies, but they also indicate that the furnace is producing excess carbon dioxide.
