When it comes to thermostats, you can expect their average lifespan to be around a decade, with some models lasting longer. Several factors like their model, make and design affect how long thermostats last. Over time, they will degrade due to normal wear and tear, wiring issues, dust accumulation and rust. However, their lifespan is null and void if you need a new HVAC system because the thermostat will then need to be replaced. 

 

Homeowners need to know how long thermostats last, the signs that their unit is failing, and the features to look for when choosing a replacement.

 

When To Get a Replacement Thermostat

 

After knowing the answer to “how long do thermostats last,” the next step is to know when you need to replace them. Identifying the signs of a failing unit will help you prepare for the colder season since you can replace it before it breaks down.

 

Here are some of the symptoms of a failing thermostat that you should look out for:

 

Short Cycling

 

Short cycling occurs when your HVAC doesn’t thoroughly heat or cool your home. It causes the entire cooling and heating system to work harder than usual. This means the HVAC cannot complete its cycles, which can significantly reduce the lifespan of your entire system.

 

Constant Temperature Changes

 

Constant temperature changes on your heating or cooling system mean your HVAC cannot maintain the desired temperature. This is one of the clear signs there’s something wrong with your thermostat.

 

Thermostat Not Responding to New Settings

 

If you notice that your home doesn’t change temperature after you enter new settings in the thermostat, it can signify that you need a new thermostat. You should be able to hear your HVAC respond when you change settings.

 

Faulty Readings

 

Faulty temperature readings mean that the sensors on your thermostat are no longer working. These sensors also signal your HVAC to turn off or on when the desired room temperature is reached. You can compare the temperature readings with an indoor thermometer to confirm this problem.

 

Higher Energy Bills

 

When thermostat sensors aren’t accurately registering accurate temperatures, your HVAC works harder, resulting in substantial increases in your monthly energy bills. When this happens, one of the first things homeowners should inspect is their thermostat to determine if it’s faulty.

 

HVAC Turns On and Off Frequently

 

When your HVAC turns off or on frequently without your input, then you have to have your thermostat inspected by professionals. Unfortunately, this means it may not be able to switch your system's heating and cooling functions correctly.

 

Your Thermostat is Ten Years or Older

 

If your thermostat is around ten years or older, it might be time to replace it. It doesn’t mean your unit isn’t functioning correctly. However, newer thermostats are more energy efficient, and you can save a lot on energy bills with a newer thermostat.

 

Non-Programmable Thermostat

 

A non-programmable thermostat isn’t faulty per se, but changing to a programmable one can save you more money in the long run. With a programmable unit, you can set different temperatures for your home on a daily or weekly schedule. You eliminate the need to change the settings manually. These thermostats automatically adjust the temperature in your home as needed, which is more efficient, and you can even change the settings while you’re out of the house if your thermostat is Wi-Fi enabled.

 

You're Still Using Analog Thermostats

 

Analog thermostats are equipped with slide levers or dials. You turn these controls to adjust your home's temperature to the desired settings. There’s nothing wrong with this system; however, they’re not as accurate as digital and programmable models. As a result, you save more money with a more precise thermostat, which can better maintain your home's temperature.

 

Choosing the Most Suitable Thermostat for Your HVAC System

 

When shopping for a new thermostat, you should know the features to look for in a new unit:

 

• Smart and learning features that can determine your preferred settings.
• Remote management features allow you to change settings even when you’re away.
• Programmable settings that you can configure for each day or week.
• App controls will enable you to change settings using an app on your phone.
• Reminders and auto changeovers come in handy for better temperature management.
