The thermostat is connected to the furnace or central air system and can control both heat and cool air. It also monitors the temperature of the room and sends a signal to activate heating and cooling systems as temperatures fluctuate.
Over time, your thermostat can break down and need repair or replacement. You might also want to install a smart thermostat you can control via a mobile device. Get more information about replacing a thermostat below, including the replacement cost.
What Are Some Signs You Need to Replace Your Thermostat?
You may want to replace a thermostat if the old one isn't working well, or you want to upgrade to a more technologically advanced option.
There are five tell-tale signs you need to replace an old thermostat:
- The heating or cooling system won’t start up anymore. This typically means the thermostat is no longer communicating properly with your furnace or HVAC unit. This usually happens when the sensor goes bad.
- Temperature readings are incorrect. One way to test this is to use a portable thermostat to get a reading in the house. If the reading is different from the one used for the cooling and heating systems, you might have to replace it.
- Energy bills keep going up unexpectedly. A faulty thermostat is known to cause heating and cooling systems to overwork because the equipment isn't getting a signal to shut off once the target temperature has been met. This causes an increase in energy consumption and higher utility bills.
- The temperature is always noticeably fluctuating. This can be the result of a faulty thermostat, but it could also be a problem with the heating and cooling equipment. In this scenario, it’s best to have a professional cooling and heating expert come in and check the thermostat and equipment before you go ahead and change the thermostat.
- It’s just plain old. Thermostats typically have a 10-year lifespan.
In some cases, the problem isn't the thermostat at all. The issue could simply be that you need to replace the battery in the unit, if applicable.
