Signs It’s Time To Replace Your Thermostat

Know When to Replace the Thermostat

It’s essential to know when to schedule a thermostat replacement in a home to keep HVAC systems operating correctly. If it fails, a home’s air conditioner cannot turn on and off as expected, and the temperature in the house will rise to an uncomfortable level.

To avoid these problems, homeowners should recognize broken thermostat symptoms to know when to install a new thermostat. Some signs to watch include increasing utility bills, incorrect temperature readings, and short cycling.

Higher Energy Bills

There are many signs homeowners should watch for that can indicate they have a broken thermostat. One sign is high energy bills. If a thermostat malfunctions, it can cause the HVAC system to overwork, which can use more energy.

It can waste energy by:

  • Not accurately reading the temperature or failing to communicate with the heating and cooling systems properly. It can fail to turn off the HVAC system, causing more energy to be used.
  • Causing the air conditioner to run continuously, especially if it malfunctions and is stuck in the “on” position.
  • Delayed response times to temperature changes, causing households to adjust the temperature reading and increasing energy usage.
  • Programming errors that can cause a smart thermostat to fail to follow the programmed settings and cause the system to run when it’s not supposed to.

Incorrect Temperature Readings

Another sign homeowners must watch for is if a thermostat shows incorrect readings. Property owners should recognize the symptoms that a thermostat is failing and needs to be replaced, including:

  • Significant differences between the displayed temperature on the thermostat and the actual room temperature
  • Failure to reach the set temperature, even when the air conditioner keeps running, trying to achieve it
  • Sudden temperature changes in a home
  • Short-cycling of the HVAC system, causing it to turn on and off quickly without reaching the temperature setting
  • The unit’s buttons or screen are unresponsive

Short Cycling

Short cycling is another sign that a thermostat is malfunctioning. If an HVAC system turns on and off quickly without reaching the desired temperature setting, it can indicate a problem with the air conditioner or that the thermostat needs to be replaced.

Faulty thermostats can cause short cycling due to:

  • Malfunctioning sensors that cannot detect the temperature
  • Wiring problems or poor connections between the thermostat and the system
  • Damaged components in the thermostat prevent it from accurately controlling the heating and cooling cycles
  • Compatibility issues between the thermostat and the HVAC system
  • Accumulating dirt, dust, and debris inside the thermostat can interfere with its ability to function
