When Is The Right Time To Replace Your Furnace?

It’s difficult to know if your furnace should be replaced. There usually aren’t a lot of external signs; however there are some basic considerations to help you make an informed decision.

Age

  • Based on industry averages, a 20-year-old furnace could be nearing the end of its life expectancy and investing in a new heating system may be a better option than dealing with costly repairs on an aging unit.

Efficiency and Savings

  • Furnaces have become more efficient as a result of new technology. Newer heating oil furnaces have efficiencies above 80%, and propane furnaces can have efficiency ratings as high as 94%.

Size

  • It is important for your furnace to be properly sized for your home to run at peak efficiency during the winter, especially if you have recently taken steps to make your home more energy efficient. An oversized furnace can be less efficient than a properly sized one, potentially costing more money to heat your home.

Reliability

  • No matter how old your furnace is, we suggest an annual cleaning and inspection to make sure your furnace is working properly and to help identify issues. A proactive decision puts you in charge of the timeline, and can help avoid an unexpected break down in the middle of winter.

  1. I appreciate the information for replacing a furnace. I didn’t know that furnaces lasted about 20 years. I will have to look at replacing mine, since it’s 21 years old.

  2. That’s amazing that the newer propane furnaces have an efficiency rating of 94%. Although my furnace is only 12 years old, I’m thinking of getting a newer one. I would be saving money over time that way.

  3. Recently my mother’s furnace has stopped working and winter is coming and she needs to replace it. You mentioned that furnaces have become more efficient as a result of new technology and newer heating oil furnaces have efficiencies about 80% and propane furnaces can have efficiency ratings as high as 94%. Do most contractors have these varieties that they can install? It seems contacting a contractor could be beneficial for her.

    My husband and I moved to an older house a few years back and am wondering if or when I should replace the furnace. I like how you pointed out reliability and getting an annual inspection to make sure it is working properly and if there are any issues. I haven’t gotten an inspection since moving here so I think it would be important to get an inspection and see what the contractor says about the furnace and then going from there to decide if it needs to be replaced or not. Thanks for all the useful information!

  5. I think I’ve had my furnace for about 20 years now. According to this post, I should have a new heating system installed. I’m actually glad to say that because I’ve had to get my heating repaired several times already. Having a new heating system installed will save me a bundle!

    I thought all furnaces were pretty much the same size and push the same amount of heat, but it makes sense now that I think of it. I thought it was interesting that an over-sized one is less efficient. I guess it’d be good to do your research on what you would need before you get one. Thanks for the info!

  7. I didn’t know that new heaters could have so much better energy efficiency. Propane is something we’ve been considering, and at 94% energy efficiency, they sound even better and better! I will have to show my husband these facts and see what he thinks we should do. Thanks for the great info!

  8. This is some great information, and I appreciate your suggestion to have your heating system cleaned and inspected annually. I installed a new heating system a few years ago, and it hasn’t been inspected since its installation. I’ll definitely look into having that done soon and I’ll be sure to have it done every year in the future. Thanks for the great post!

    What’s interesting is, not too many people know about how efficient new furnaces can be. If you can squeeze more efficiency out of your heating and cooling equipment, you can save a lot of money on your monthly energy bills. Upgrading from an old, inefficient furnace to a new, high-efficiency model can pay for itself in the long run.

  10. I recently moved into a pretty old home, and I have been loving its charm. However, I came to realize that a lot of it needs to be replaced. I have set out to get it entirely up to date as far as utilities go, but I was unsure if the furnace needed replacing. It is so nice to have a list of things that I should probably check on for this type of thing. Thank you for all of the helpful information, I will be contacting a professional about this soon!

  11. I didn’t know that a furnace needed to be replaced, or at least looked at to see if needs replacing, after 20 years. I have a family member that lives in an old house and she probably hasn’t checked her furnace. I will have to tell her about your tip!

  12. Thanks for sharing this information with us. You’ve listed some things that I haven’t ever thought of! I think it’s time to replace my furnace; I’d like to switch it out for a propane heater because—like you’ve mentioned—they can have efficiency ratings as high as 94 percent. Great post! I’ll share it with some of my buddies.

  13. I believe that the furnace in our current home is quite old. We are not sure if it is reaching the end of it’s lifetime, but it is probably as old as 20 years, or very close. Either way, reading that newer furnaces are more efficient is a big draw to wanting a new one. Thanks for the advice and information.
