Furnace Thermostat Issues

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 Outdated Thermostat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.

Twintech promptly responded to request for quotation. They were thorough and helpful in explaining options. The quote was very competitive. Installation of new furnace was very professionally completed. Excellent work.

by Rita, Scarborough on Twintech Heating and Cooling

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.

by Bob S, Pickering on Twintech Heating and Cooling

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 we’ve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

by Brent L on Twintech Heating and Cooling

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.

by Karen on Twintech Heating and Cooling

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didn’t 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.

by Rob on Twintech Heating and Cooling

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.

by Linda Robinson on Twintech Heating and Cooling

They were on time and very professional. I'm so glad I decided to go with Twintech, thanks!

by Famcam1953 on Twintech Heating and Cooling

Timely and appreciated - this was during the hottest days this year when our Air and Furnace way.
Efficient. Professional. No BS or overselling. What was promised, was delivered at a cost-effective price point.
Down to earth.

by DG Sellers on Twintech Heating and Cooling

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.

by Bill, Pickering on Twintech Heating and Cooling

Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.
