Should You Replace Your Furnace?

Are you dealing with a faulty furnace? If you are considering whether to replace or repair your furnace, review these facts to ensure you make the right choice.

  • Newer units come with a warranty, which help you save on repair costs should any issues arise.

Green Benefits

Comfort and Air Quality

  • Newer systems do a better job of controlling temperature and humidity, which reduces mold and mildew growth, improving both comfort and air quality in your home.


Newer Systems

  • For new or relatively new systems, it is likely that repairs make the most financial sense.

The 50 Percent Rule

  • If the cost for repair versus replacement of your system is less than half of its value and you haven’t been suffering the need for monthly service calls to keep your system up and running, repair may be easier on your checkbook.


  • If you are planning on moving out of your current home in the immediate future and your system is still working, talk to your local real estate agent to determine whether either repair or replacement would be in your best interest.


  • If your system is sitting on the fence – neither old nor new -- some simple maintenance techniques may help prolong its lifespan and make immediate replacement unnecessary.
