How long should your heater last before replacement? This is a common question many people ask immediately they start experiencing trouble with house heating in Roswell, GA.

Well, there is no exact answer to this issue. Your heater’s lifespan depends on many factors, including how often you use it and the maintenance schedule. If you maintain it well, a good heating system should last anywhere from 10-15 years.

While we can’t state a precise time your heater should last, we can provide you with tips on making it last longer. We can also guide you on some crucial furnace replacement signs. Read on to find out.

Factors that Affect the Lifespan of Your Heater

The following factors will determine how long your heater will last:


If you’re buying a heater for your home, size is a significant factor. Smaller spaces can get away with smaller heaters, while bigger homes need more powerful units to provide sufficient warmth. Placing a smaller heater in a large room would be straining it, hence reducing its lifespan. Our professionals can conduct a load calculation to get you the right sized heater.


Ensure your heater is installed correctly to avoid performance and reliability issues. Check to confirm that all ducts, flues, and vents are free from obstructions during the installation process. An efficiently functioning heater is likely to last to its fullest lifespan.


Having your heating system maintained by a licensed professional once or twice a year can extend its lifespan. Heaters are constructed with many moving parts. Each of these parts needs to be kept in working order for your heater to continue running smoothly.

Thermostat settings

Set your thermostat to a comfortable point. If you are comfortable, your heater will run less and use less energy than if it is cranked up super high. The recommended thermostat setting should be between 60 to 80 degrees Fahrenheit.

Frequency of Use

Overusing your heater could lead to overheating, a major cause of appliance failure. So, ensure you use your heater only when it matters. Otherwise, let mother nature do her job.

Signs That It’s Time to Replace Your Heater

Consider replacing your heater with a newer model if:

  • Loud noises are coming from your heating system
  • There are leaks inside the unit
  • Your energy bills keep rising
  • The air coming from the vents isn’t warm
  • You call the maintenance service frequently
  • There are uneven temperatures in the house

Tips to Extend the Lifespan of Your Heater

If you want to get the most out of your heater’s lifespan:

  • Ensure there is enough ventilation around your home (i.e. don’t block any vents)
  • Switch off your heater when you leave your home
  • Clean the dust filter regularly
  • Get frequent service checks
