You’re here because you want to know how to know when it’s time to replace your furnace.

Bad news is…your furnace won’t last forever, unfortunately.

But the good news is, fortunately, we have prepared a checklist that will help you identify when it’s time to upgrade your system so you can stay comfortable during these cold winter nights.

Read more below to find out what to look for when it’s time to replace your furnace.


How will I know it’s time to replace my furnace?


Your Furnace Is More Than Fifteen Years Old

While a modern furnace will last for about 20 years, it’s good to start shopping for a new system around the 15-year-old mark.

Your Energy Bills Keep Going Up

Older furnaces work harder to produce heat, and as a result, you can expect to see higher energy bills.

In the long run, it is advisable to purchase a more efficient unit rather than paying for repair after repair when your HVAC system has come to the end of its lifespan.

Rooms In Your Home Have Different Temperatures

Older units have trouble distributing heat evenly throughout your house. Some rooms will be cooler and some rooms warmer. This is a definite sign it’s time to make an HVAC change soon.

You See Soot Around The Register

The ventilation duct cover that opens and closes is your furnace register. If you find soot, rust or dust in different areas of your home, this means your furnace has too much CO2. Health issues can occur such as sore throat, dry eyes and upper respiratory infections as well.

Your Furnace Is Making A Lot of Noise

Your furnace should never make sounds like rattling, popping, humming or screeching. If you are hearing these sounds, it is generally a clear sign that you need a new HVAC system.
