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 Outdated Thermostat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.

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

My furnace broke down last month. The team was quick to respond, courteous, professional and mindful of COVID-19 concerns. I highly recommend them if you are considering replacing or servicing your HVAC equipment.
