When to Replace Your Thermostat

Signs Thermostat Replacement May Be Needed

A malfunctioning thermostat can leave homeowners stuck in an uncomfortable home, paying more than necessary to run their heating and cooling systems, and it can put more wear and tear on the system. While these devices might seem like a minor part of HVAC systems, they play a significant role in ensuring the heating and air conditioning work correctly and know when to turn on and off. Homeowners can stop these effects by watching for broken thermostat symptoms that indicate they may need a thermostat replacement.

Unusually High Energy Bills

When homeowners check their monthly utility bills and notice a high energy bill, they will begin trying to figure out what caused the extra energy use. What they might not suspect is a malfunctioning thermostat could be the cause of the increase. When a thermostat malfunctions, it can interfere with the heater and air conditioner’s operation, wasting energy.

Households rely on the thermostat to work correctly and communicate with the system to prompt it to turn on and off based on the temperature in the house and the programmed settings. If the thermostat malfunctions because of issues like loose wires or a faulty temperature sensor, it can fail to communicate with the HVAC system properly.

If the system keeps running or overworks due to problems, it wastes energy, raises energy costs, and puts more wear and tear on the unit. Homeowners with smart thermostats can also experience these issues. If the thermostat malfunctions, it can cause the unit to fail to turn on and off according to the programmed settings.

Fails to Read the Correct Temperature

If there are incorrect temperature readings from the thermostat, it can indicate the device needs to be replaced. Homeowners should pay attention to whether the house feels warmer or cooler than the temperature reading on the thermostat. If they suspect the temperature is wrong, they can confirm their suspicion by using an indoor thermometer near the thermostat and comparing the temperatures they read.

If there is a contrast between the thermostat’s temperature reading and the actual temperature, it means the thermostat is not accurately reading the temperature and may need to be replaced. This issue could be caused by several issues, such as a malfunctioning temperature sensor, an old mercury-based thermostat that isn’t level, or it is located in the wrong area of a home exposed to drafts or direct sunlight. HVAC technicians can inspect the thermostat and determine whether a thermostat repair would suffice or if the house would benefit from a replacement.

Short Cycling

A malfunctioning thermostat can also cause heaters and air conditioners to short cycle. This happens when the unit turns on and then quickly turns off before completing its normal heating or cooling cycle length, which can cause additional wear and tear on the system. This is because when the thermostat is faulty, it cannot correctly prompt the system to turn on or off.

Thermostat issues, like faulty wiring or dust and dirt in the device, could be possible causes of the short cycling. If a homeowner notices their heater or air conditioner is short cycling, they should schedule an inspection with an expert. They can determine if the issue is due to a faulty thermostat or another problem with the system.
