Why is my Furnace Thermostat Acting Buggy?

Why is my Furnace Thermostat Acting Buggy?

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:


  1. 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.


  2. 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.


  3. 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.


  4. 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.


  5. 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.


  6. 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.


  7. 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.


  8. 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.


  9. 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.


  10. 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.

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 air conditioner failed. Made a call and within 15 min a technician was at our door.
The issue was fixed and many suggestions were provided.
Thanks to Mitch. Great service !

by Kazuko on Twintech Heating and Cooling

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.

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

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!
