Can a Low Battery in Your Thermostat Affect Your HVAC?

Is your HVAC system not heating or cooling your home correctly? If you inspect all parts of your unit and can’t seem to pinpoint the cause, it’s important to turn toward your thermostat. While it may not always be an obvious reason, your thermostat can affect your HVAC’s performance more than you’d think.

Will a Low Battery in Your Thermostat Affect Your HVAC Performance?

Yes, a dying battery in your thermostat can have an impact on your HVAC system. If your thermostat’s battery is low, it can cause your HVAC unit to function erratically or potentially not at all. Your thermostat plays a huge role in how your HVAC unit functions as it regulates the temperature of your system.

If the thermostat batteries are low, then the thermostat won’t be able to function as intended, meaning it can’t aid your heating and cooling systems in proper operation. When you notice your HVAC system is struggling to keep up with your heating and cooling needs, it’s worth it to check in on your thermostat’s battery life. Some ways a low battery in your thermostat can affect your HVAC’s performance include:

• Your unit isn’t producing adequate airflow
• Your system fails to keep an even temperature
• Your energy bills are abnormally high
• Your unit takes longer than usual to turn on or off

How Do You Change a Thermostat's Batteries?

On some thermostats, such as smart or Wi-Fi thermostats, there is an indicator that will notify you of a low battery. If yours notifies you or you feel as though your batteries need to be changed due to a lack of HVAC performance, doing so as soon as possible is your best bet.

Generally speaking, thermostat batteries last roughly eight months to a year, so annually changing them is a necessary routine. To do so, you’ll have to carefully remove your thermostat from the wall and locate the battery compartment on the back or bottom, replace the old batteries with the required type of new ones, and place your thermostat back on the wall.

What Other Maintenance Issues Affect HVAC?

There are a few different maintenance issues that can affect how your HVAC unit runs. However, there are some maintenance tips and tricks homeowners can perform to ensure their HVAC system is always working as it should. These maintenance tasks include:

• Clean or replace air filters
• Ensure all components are clean
• Replace worn-out parts
• Remove dirt and debris from vents and ductwork
• Make sure your circuit breaker is working appropriately
• Change out your thermostat’s batteries
