The thermostat plays an important role in your HVAC system’s operation. Unfortunately, while these devices are designed to last a decade or longer, eventually they wear out and stop working properly. When this happens, it can cause your heating and cooling units to run inefficiently, increasing energy costs and making it difficult to regulate indoor temperatures. Here are some of the telltale signs you need a new device.

How to Know It’s Time for a New Thermostat

1. Incorrect Readings 

Your thermostat is responsible for monitoring the temperature inside your home and determining when the heater or air conditioner needs to turn on. However, if it begins registering incorrect readings, the HVAC system won’t run when it should. 

This typically occurs due to a malfunctioning sensor. You can use a portable indoor thermometer to measure the temperature and verify the thermostat’s accuracy.

2. Short Cycling

When your heating or air conditioning unit comes on, it should run until the thermostat recognizes that the preferred temperature has been met. If the equipment is short cycling, it will shut off before completing an entire heating or cooling cycle. 

This is often caused by a thermostat that's no longer syncing with the HVAC system. Under these circumstances, you should consider investing in a new device, as short cycling will wear out your equipment faster. 

3. No Response to Changed Settings

As changes are made to your thermostat settings, you should notice the device responding to those adjustments right away. Usually, you’ll hear a clicking noise to indicate the equipment is starting up, but if nothing happens, that’s a clue the device isn’t communicating with the rest of the system. An HVAC technician will be able to diagnose the issue and confirm if a replacement is necessary. 

4. Outdated Technology 

Even if your thermostat seems to be working right, you might want to replace it with a newer, more efficient model. Analog thermostats only perform basic functions, while programmable devices provide better temperature control. You’ll be able to set different temperatures according to a daily or weekly schedule, which will minimize your energy consumption and save you money on heating and cooling expenses.
