Furnace Thermostat Issues
Posted On: October 24, 2024
Furnace thermostat issues can lead to inefficient heating and discomfort, especially as temperatures drop. If your furnace isn’t functioning properly, the thermostat could be a common culprit. Here are some common thermostat-related problems and how to address them:
1. Incorrect Thermostat Settings
- Problem: Sometimes, the thermostat is simply set incorrectly, either switched to "cool" instead of "heat" or with an incorrect temperature setting.
- Solution: Ensure the thermostat is on the “heat” setting and the temperature is higher than the current room temperature.
2. Thermostat Placement
- Problem: If your thermostat is placed near heat sources like sunlight or in a drafty location, it may cause inaccurate readings.
- Solution: Relocate the thermostat to a central location away from direct heat or cold sources for more accurate temperature control.
3. Wiring Problems
- Problem: Loose or damaged wiring can prevent the thermostat from communicating with your furnace.
- Solution: Check for frayed or disconnected wires behind the thermostat. If you’re not comfortable handling electrical components, contact a professional HVAC technician.
4. Dead Batteries
- Problem: If your thermostat is battery-operated, dead batteries can cause it to stop working.
- Solution: Replace the batteries and check if the thermostat resumes normal operation.
5. Thermostat Calibration
- Problem: Over time, a thermostat can lose calibration, meaning the actual room temperature doesn’t match what the thermostat reads.
- Solution: You can recalibrate some thermostats by following the manufacturer’s instructions. If that’s not possible, consider replacing the thermostat.
6. Outdated Thermostat
- Problem: Older, non-programmable thermostats may become less efficient or unresponsive as they age.
- Solution: Consider upgrading to a modern programmable or smart thermostat for better energy efficiency and more precise control.
7. Furnace Cycling Issues
- Problem: If your furnace is short-cycling (turning on and off too quickly), it may indicate a thermostat problem or improper placement.
- Solution: Check the thermostat settings and location. If the problem persists, you may need a professional HVAC inspection.
8. Dirty Thermostat
- Problem: Dust and debris can accumulate inside the thermostat, causing mechanical or electrical malfunctions.
- Solution: Clean the inside of the thermostat gently using a soft brush or compressed air.
Addressing these common thermostat issues can help restore your furnace’s efficiency. If troubleshooting doesn’t solve the problem, it may be time to consult an HVAC technician.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
