How Long Should a Thermostat Last?

The thermostat is one of the most important components of your home’s HVAC system, and it’s essential for maintaining comfortable temperatures year-round. But how long should a thermostat last? It’s not always easy to answer this question, as it will depend on the type of thermostat you have and how well you maintain it. Atomatic Mechanical Services, Inc. discusses the average life expectancy for a thermostat and some signs that your thermostat should be replaced.

The Average Life Expectancy of a Thermostat

On average, thermostats tend to last around 10 years with proper maintenance and care. That said, if it’s been more than a decade since you installed a new thermostat, it’s likely time to replace your current unit. Older models may become outdated or require more frequent repairs due to wear and tear over time. A good time to replace your thermostat is when you replace your HVAC system. When its time to upgrade to a new heating or cooling system, a new thermostat ensures that your thermostat is compatible with the rest of your home comfort system.

How Long Should a Thermostat Last?

The average lifespan of a thermostat varies for different homeowners. Your thermostat should last for many years with regular maintenance and an occasional battery change. However, there are some signs that indicate it may be time for a thermostat replacement sooner rather than later. These include:

Your Home is Too Hot or Too Cold

If your home is constantly too hot or too cold, it could be a sign that your thermostat is not working properly. A faulty thermostat can cause your heating and cooling system to run constantly, which can lead to higher energy bills. Additionally, an incorrect temperature in your home can be uncomfortable for you and your family.

Higher Energy Bills Than Normal

If you notice that your energy bills are suddenly higher than they typically are, it could be a sign that your thermostat needs to be replaced. A faulty thermostat can be causing the heating or cooling system to run unnecessarily, consuming more energy than needed. Your thermostat should take an accurate temperature of the entire house. Sometimes if a thermostat is placed in a drafty room or on an exterior wall, this can throw off the thermostat’s readings. Consider moving your thermostat to a different area of the house to see if that helps.

Your Thermostat is Outdated

If your thermostat is more than 10 years old, it may be time to replace it with a newer model. Newer thermostats are more energy-efficient than older models, which can help to save you money on your energy bills. Additionally, newer thermostats like programmable thermostats and smart thermostats often have additional features that can make them more convenient to use, such as creating schedules and remote access.

Your Thermostat is Malfunctioning

If you notice that you have a malfunctioning thermostat because you have difficulty changing its settings, it is likely time to replace it. A broken thermostat that cannot accurately control your HVAC equipment, the home will not be comfortable and your heating and cooling systems are likely to waste energy.

You Want to Upgrade Your Thermostat

If you are interested in upgrading to a programmable thermostat or a smart thermostat, go ahead and replace your old one. Smart thermostats are designed to be more energy efficient than traditional thermostats. If you’re still using a manual thermostat, then you’re well due for an upgrade. New thermostats can have a schedule to set temperatures in your home at certain times, and others can be controlled with your virtual assistant or smartphone.
