Why is my Furnace Thermostat Acting Buggy?
Posted On: October 7, 2023
A furnace thermostat can behave erratically or "buggy" for several reasons. Here are some common issues and troubleshooting steps to help you identify and resolve the problem:
-
Dead Batteries: Many thermostats are battery-operated. If the batteries are low or dead, the thermostat may not function properly. Replace the batteries and see if that resolves the issue.
-
Thermostat Placement: Ensure that the thermostat is placed correctly. It should be away from drafts, direct sunlight, heat sources, and not obstructed by furniture or curtains. Incorrect placement can lead to inaccurate temperature readings.
-
Dirt and Dust: Dust and debris can accumulate inside the thermostat, affecting its performance. Clean the thermostat gently with a soft brush or compressed air to remove any dirt that might be causing problems.
-
Wiring Issues: Check the wiring connections between the thermostat and the furnace. Loose or corroded wires can cause intermittent problems. Make sure all wires are securely connected.
-
Settings: Review the thermostat settings to make sure they are configured correctly. Double-check the temperature setting, mode (heat, cool, fan), and programming if applicable.
-
Software/ Firmware Updates: If your thermostat is a smart or programmable thermostat, it may need a software or firmware update. Check the manufacturer's website or app for updates and follow the instructions to update your thermostat.
-
Compatibility: Ensure that your thermostat is compatible with your heating system. Some older thermostats may not work well with newer HVAC systems, and vice versa.
-
Interference: Wireless thermostats can sometimes experience interference from other electronic devices or Wi-Fi networks. Try relocating the thermostat or adjusting its settings to reduce interference.
-
Faulty Thermostat: If none of the above steps resolves the issue, your thermostat may be malfunctioning or faulty. In this case, you may need to replace it with a new one.
-
HVAC System Issues: Sometimes, the problem may not be with the thermostat itself but with the furnace or HVAC system. It's a good idea to have a professional HVAC technician inspect and diagnose the entire heating system if you're unable to resolve the issue with the thermostat.
If you're unsure about any of the troubleshooting steps or if the problem persists, it's best to consult a qualified HVAC technician. They can diagnose the issue more accurately and recommend the necessary repairs or replacements.

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

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 !
