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 Outdated Thermostat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.

It was a refreshing experience interacting with the Twintech team. From Bob, the sales consultant, who articulated in layman's terms all the options available and reasons for making any selection. This was done without the prevailing pressure tactics so commonplace today.
Before proceeding Mitch, the technician, at our request conducted a service check on our 30 yr old furnace. His report was positive indicating no urgency to replace it. Again no pressure tactics.
Three days after first meeting with Bob, the installation team of Greg and
Spencer completed the installation within the planned time frame.
A very professional, courteous and transparent team which delivered on their promise. I highly recommend Twintech.

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and were very friendly. Ive got 15 years in the contracting/ construction industry and these guys are one of the most professional companys Ive dealt with. Great company!

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.
