How to Spot Thermostat Issues: Key Signs and Easy Fixes

Your home's thermostat functions as the "brain" of your HVAC system, sensing the interior temperature and directing air conditioners, furnaces, or other HVAC components in their operations. A thermostat that's experiencing issues won't be able to accomplish these tasks as effectively (or at all), and knowing the signs of these issues and some potential fixes can be quite helpful.

At Airtime Heating & Cooling, we're here to help with all your HVAC needs around Draper, Herriman, and nearby areas, including everything from AC and furnace repair and replacement to help with thermostats of any kind. We regularly help clients identify and remedy thermostat issues, from simple concerns to more complex problems. Here are some simple tips on how to tell if your thermostat is bad, plus some tips on remedying these issues, whether on your own or with help from our HVAC professionals wherever necessary.

HVAC System Will Not Start

If you have set your thermostat to the desired temperature, but your HVAC system has not started, there could be a few reasons behind this issue. Here are some steps to troubleshoot and identify the root cause of the problem:

• Check Power Source: The first step is to check if your HVAC system is receiving power. Make sure that all switches and breakers are in the ON position.
• Check Thermostat Batteries: If your thermostat uses batteries, make sure they are not dead or low on charge. Replace them if necessary.
• Reset Thermostat Settings: Sometimes, resetting the thermostat settings can fix the issue. Turn off the power source for a few minutes and then turn it back on to see if the system starts.

If none of these fixes does the trick, it is likely time to contact HVAC professionals for help. The issue might be something a bit more complex with your thermostat, or it could be a problem with other components entirely. Our team at Airtime Heating & Cooling can help you identify the issue if you're in this position.

Major Temperature Fluctuations

If your system turns on and off properly but is displaying some major temperature fluctuations, there could be a few potential causes - a few of which, again, are not connected to the thermostat. You will need to confirm that your AC, furnace, or other key HVAC component is working properly as well.

But if this is the case, a few different thermostat issues may be causing temperature fluctuations:

• Sensor issues: Your thermostat relies on sensors to accurately read the temperature in your home. If these sensors are dirty, damaged, or not functioning properly, your thermostat may be receiving inconsistent temperature readings and causing fluctuations.
• Loose wiring: Like any electrical component, the wiring connecting your thermostat to your HVAC system can come loose over time. This can lead to communication issues between the two and result in temperature fluctuations.
• Faulty setting: Some thermostats have a "swing" setting that allows for a fluctuation in temperature before turning on or off. If this is set too high, it could be causing major fluctuations in temperature.

To remedy these issues, it is important to regularly check and maintain your thermostat. This includes checking for loose wiring, ensuring the settings are correct, and replacing batteries as needed. If you continue to experience temperature fluctuations despite taking these steps, it may be time to consider upgrading to a newer model or contacting a professional for help.

Thermostat Turning on and Off

The thermostat should not be an item that cycles on and off - it should remain on at all times to direct the HVAC system. If you begin to notice that it's off for certain periods, this is almost always the result of an electrical issue. It could be a loose connection, a tripped breaker, or an issue with the power supply. Check these components and, if necessary, consult an electrician to resolve the problem.

Incorrect Temperature Reading

Occasionally, you may notice that your thermostat is displaying an incorrect temperature reading. This can happen due to various reasons, such as dirty sensors, faulty wiring, or even placement of the thermostat in direct sunlight or near drafts. Try cleaning the sensors and ensuring proper placement of the thermostat for accurate readings.

As you can see, there are a few signs that might indicate your thermostat is having issues - and a few simple ways to fix them. If you need assistance with this or any other HVAC need around Draper, Herriman, or nearby areas, contact our team at Airtime Heating & Cooling today!
