Trane furnace troubleshooting isn’t something you’ll need to do often, but when trouble happens it’s easy to fix. Trane is an innovative heating and cooling company with a variety of furnaces of all makes and sizes. They’re durable units and built to last, so if you take care of your furnace you won’t run into any issues for a while.


Issues can often begin when basic furnace maintenance hasn’t been performed in some time. The easiest way to start is by changing your filters. Dirty filters can do long-term damage if they are left unclean because the ducts can get backlogged with dirt and debris. If you have a disposable filter then replace it with the proper size and if you have a permanent one, wash it with soap and water, rinse it thoroughly and let it dry completely before putting it back.


If your furnace isn’t heating then it could be an issue with the thermostat. Make sure you’ve set your thermostat correctly and that the adjustable calibration scale has been set up recently. If it’s set correctly but isn’t working then it could be a software issue. This is one of the most commonly overlooked areas in furnace troubleshooting but is the easiest fix! If this does work, it is likely the thermostat will need replacing.


Lastly, make sure the furnace is getting adequate power. If it isn’t receiving any, go to your circuit board and make sure the fuses aren’t cracked or blown. If one is blown, replace it but otherwise resetting the circuit should do the trick.

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!
