Signs to Watch for Indicating You Need a New Thermostat

3 Signs You May Need Thermostat Replacement 

While an AC system can malfunction for a variety of reasons, one possible issue many property owners overlook is a malfunctioning thermostat. If a thermostat is not working correctly, it can prevent the air conditioner from turning on when needed, fail to alert it to turn off once the house reaches a set temperature, cause higher utility bills, and even cause short cycling. 

To avoid these issues from causing more problems for the air conditioning system, HVAC contractors recommend that homeowners schedule thermostat services when they notice symptoms of a broken thermostat. The technician can then determine whether the thermostat can be repaired or needs replacement. 

Higher Than Ususal Energy Bills

Home billsWhen property owners notice high energy bills that are more costly than usual, it could be due to a malfunctioning thermostat. If the thermostat is not correctly signaling to the AC system when it needs to run and when it needs to shut off, it can result in the air conditioner running for much longer than needed. This can result in wasted energy – and higher utility bills. 

Failing thermostats can also cause family members to prematurely adjust the thermostat settings if they notice the house getting too warm. If the thermostat is slow in prompting the AC unit to turn on, a family member might start tweaking it, which can cause the unit to use more energy. 

Temperature Readings on the Thermostat Are Wrong

Home temperatureAnother symptom of a malfunctioning thermostat homeowners might notice is if the temperature reading on the thermostat does not match the actual temperature in the room and is incorrect. If the house feels warm, but the thermostat shows the house at a lower temperature, it can indicate the thermostat is malfunctioning. 

Homeowners can figure out if the temperature on the thermostat is correct by using a digital thermometer and comparing the temperatures they both show. If they are different, there is likely an issue with the thermostat, such as a faulty temperature sensor. 

Short Cycling AC

One noticeable symptom that can indicate a thermostat needs to be replaced is if a home’s air conditioner is short-cycling. If the system turns on and off quickly without completing its usual cooling cycle length or without fully cooling the house, it can indicate the thermostat is not working correctly. 

Short cycling can occur if there is an issue with the sensor, causing the device to fail to correctly communicate with the unit to prompt it when to run. It can also be due to a wiring issue or a dirty thermostat. Because short cycling can also occur if there are other issues with an air conditioner or the thermostat, it’s crucial to have it inspected by a professional.
