Consider This When Buying A Used Furnace

Published: September 29, 2021

If your furnace stopped working, you may be interested in purchasing a new one. Everyone knows that buying a new unit can be incredibly expensive, so it’s fair to consider looking into other options like buying a used unit. There are pros and cons to either option, but here are some things to consider if you’re going to buy used.

Avoid Private Sellers If Possible

Picture this: You’re surfing the internet looking for a private seller when you see a deal that just can’t be beat. You quickly message the seller and purchase the used furnace, only to find out it’s a complete dud. Now what? You can’t get in touch with the seller and you’ve lost hundreds. This scenario is why it’s best to stick with a commercial seller if possible. Commercial sellers are trustworthy and refurbish the equipment. As an extra precaution, bring a third party to inspect the unit and ensure everything is functioning properly.

Questions To Ask Your Seller

Don’t let the low price be your deciding factor. Come prepared with good questions to make sure you are getting a quality product. Asking questions will reduce the likelihood of getting scammed. Here are some examples:

  • Why are you selling the furnace?
  • How old is the furnace? (remember, units manufactured pre 2010 can not be refurbished)
  • Has it been regularly maintenanced?

There are many other questions you can ask, so come prepared with a list written out. An honest seller won’t be intimidated by this and will be happy to oblige.

Problems To Look For

If you’re able, bring a  professional with you to look at the equipment. They will be able to identify common issues. If you’re not able to, examine these common components and look for any aggressive wear and tear: pilot light, heat exchanger, burners, blower fan, limit switch, pressure switches, roll out switches, and any other components making a rattling or squeaking noise. 



Buying used is always an option, but if you’re unable to have it professionally installed, you could run into many issues down the road such as incorrect ductwork causing leaking.

Consider Alternatives

Used furnaces can work for many, but there is always a risk. Consider looking into wholesale stores for new furnaces at discounted prices. The furnaces will be new, but a significant cost reduction.
