When Is a Thermostat Replacement Necessary?

Signs Homeowners Should Replace Their Thermostat

Thermostats are a crucial part of the HVAC system that lets the system know when to turn on or off to reach the desired temperature. A typical thermostat can last around ten years with proper maintenance. Although programmable and smart thermostats are now commonly used, this does not mean they will work forever. Certain signs can alert homeowners to the possibility that thermostat replacement is needed. 

High Energy Bills

Broken thermostats can cause a sharp increase in monthly utility bills. This can be caused by a broken system component or the thermostat’s age or condition. If the thermostat cannot correctly read the room’s temperature, the HVAC system may work twice as hard to provide comfort to a space that doesn’t need it.

To find out how much homeowners pay for their air conditioning and heating, they must monitor their bills throughout the year. A sudden increase can be due to a faulty thermostat or another issue with the HVAC system, so a professional should be called when this sign is noticed.

Wrong Room Temperature on the Thermostat

A faulty reading is one of the most obvious signs of a broken thermostat. For example, if the thermostat reads 70 degrees, but the living room feels 80, this is usually a sign of old age or a broken temperature sensor. Homeowners can check the accuracy of their thermostat’s temperature reading using an indoor thermometer next to the thermostat. 

Before replacing the thermostat, HVAC technicians may be able to get rid of the problem with a thermostat repair. Since the temperature sensor can cause a faulty reading, a thorough cleaning or repair will sometimes help. The thermostat may need to be recalibrated or replaced if the reading is still incorrect. 

Shorter Air Conditioning and Heating Cycles

Homeowners who experience shorter than normal air conditioning and heating cycles also need to have their thermostats professionally inspected and possibly replaced. Short cycling happens when the HVAC system turns off before the room reaches the desired temperature. The sound of the air conditioning or heater turning on and off frequently is a common warning sign. 

Air conditioning or heating cycles that last less than 15 minutes are considered short, depending on the size of the home. Even though shorter cycles may seem like they are running less and saving energy, they actually cost more in the long run and aren’t good for the system. If a thermostat is causing short cycling, this can be due to various factors. Thermostats placed near a window or a large vent are not as accurate as those installed in a windowless hallway. Simply moving the thermostat may fix the problem.
