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.

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.
May 2, 2020
The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didnt seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
