Can You Sell a Used Furnace? Expert Tips And Tricks

Selling a used furnace? It’s possible, but there are conditions. Permission from the original buyer is required, warranty guidelines must be followed, and it needs to be professionally installed. As a professional HVAC expert, I suggest getting a new one, as used equipment can have issues. If you must sell it, make sure all ductwork is still in place and the BTU matches your home size. Recently, I encountered a customer who got a used furnace from someone who claimed to have been in business for years. Turns out, the seller was a jackass! Installation cost more than a new one, leading to some unhappy customer support calls.

Purchasing A Used Furnace

When it comes to purchasing a used furnace, there are some things to think about. Check out the original message for info on age, brand, model no., and past use. As a pro in HVAC, make sure you ask permission before replying.

Also, ask the seller for more details like maintenance and history. Some manufacturers don’t cover warranties on used furnaces, so stay honest with buyers.

If you’re buying a used furnace, ensure it’s serviced and installed by professionals. Don’t get conned by someone who claims they can do it right without understanding HVAC. Make sure the furnace you buy is the right size and number of BTUs for your home or building.

Selling a Used Furnace

Finding a buyer for a used furnace can be hard; especially if it’s been used for a while or has issues. But, with patience and the right approach, you can find someone who wants to buy it. 

  • Firstly, make sure you have all the necessary permissions. 
  • Hire a technician to check it out, as well. 
  • Be honest about any problems with the furnace. 
  • Do your research on the market prices for similar units, and advertise it in local classifieds, online marketplaces, or social media groups.

An HVAC contractor will be able to advise you if it’s a good idea to sell it or buy a new one. Selling a furnace privately can be tricky, but not impossible. 

Be honest, and have all the facts available – then you’ll find a buyer soon enough.

Buying a New Furnace or HVAC System

Want to buy a furnace or HVAC system? Here’s some info to help you decide. Consider the size of the home/space, efficiency rating, fuel source, and installation/maintenance cost.

Don’t just replace old with new; ductwork needs attention too. Buying used may have safety/warranty issues. 

Best to invest in new equipment installed by a pro. Research and get quotes from trusted contractors and find a balance between initial cost and long-term savings.

Furnaces are like cookies – they can crumble easily if not handled with care.

Common Problems with Furnaces and HVAC Equipment

Furnaces and HVAC equipment are a hefty investment for any homeowner. But, like with all other machines, they have their own problems. Let’s take a look:

  1. Dirty filters: If you don’t replace the filters, it can cause blockages in the ducts, reduce efficiency and bump up your energy costs.
  2. Misaligned burners: Misaligned burners can cause strange noises and stop your house from heating up properly.
  3. Noisy motors: Motors can make screeching or squealing sounds when starting or running if the belts or ball bearings inside them are worn out.
  4. Pilot light failure: A pilot light that won’t stay lit might be a sign of a problem with your thermocouple or gas valve and you’ll need help from a pro.
  5. Lack of maintenance: Experienced technicians can spot potential system failures before they get costly. Regular tune-ups are key.
  6. Incompatible equipment: Neglecting to update ductwork when getting a new furnace could cause bad air circulation and heating/cooling problems.

Also, picking a good installer is just as important as finding the right unit. A top-notch contractor will make sure everything is working properly from day one.

Staying informed about common issues is key to keeping furnaces and HVAC equipment in shape. Simple changes like setting appropriate thermostat temperatures can help too. Also, furnaces and HVAC equipment need regular care to work well. 

Don’t be caught off guard – keep an eye out for issues and take action to prevent major repairs.


When offloading a pre-owned heater and HVAC gear, there are many factors to bear in mind. First, make sure the apparatus is in good condition and working fine. Additionally, be aware of the age and maintenance record of the unit. Selling pre-owned equipment may cancel any warranties that came with it. Something unique to consider when trading a used furnace or HVAC apparatus is getting a pro installer. It is essential that a licensed contractor sets up the unit to dodge any potential safety risks or technical troubles later on. Be frank about any problems or issues with the hardware. This can build trust and contentment for potential customers.
