5 Signs Your Thermostat Reading Is Inaccurate

Your home’s thermostat is one of the most important components of your HVAC system, as it measures and controls your home’s temperature. When you have an inaccurate thermostat, your HVAC system won’t generate enough cool or hot air to match your setting. Fortunately, knowing the five main signs of an inaccurate thermostat can help you get ahead of the problem and solve it before it impacts your quality of life.

1. Your Home Doesn’t Feel Like the Temperature Displayed on Your Thermostat

The most obvious sign that you have an inaccurate thermostat is if your home feels colder or warmer than the temperature you’ve set. For example, if you’ve set your thermostat to 70 degrees, but you’re sweating indoors and your home feels like it’s in the 80s, your thermostat likely has an issue

While you can usually tell if a thermostat is inaccurate based on how a room feels, you could also compare your thermostat’s reading to a separate portable thermostat’s reading. If the two thermostats show different temperatures, an HVAC technician will need to inspect your thermostat to find out what’s causing the inaccurate thermostat reading.

2. Your Thermostat Is Installed Near An Area Prone to Temperature Swings

If your thermostat is installed near a place in your home where the temperature consistently swings, your thermostat’s reading is likely off. For instance, a thermostat near a door will likely experience various temperature swings as people enter and exit your home. A thermostat exposed to direct sunlight can also be affected, as the sunlight can make the thermostat believe your home is warmer than it actually is.

Typically, this issue can be solved by installing the thermostat in a new location. However, if your home isn’t properly zoned, you could also need home zoning services to prevent temperature fluctuations.

3. You Have a Mercury-Based Thermostat That Isn’t Level

Another sign that you have an inaccurate thermostat is if you’re still using a mercury-based thermostat that’s not level. These older thermostats are usually installed in older homes and need to stay level to provide an accurate reading.

If you have one of these thermostats and it’s not in a level position, you’ll need to adjust it back to a level position to get an accurate reading. However, it’s usually best to replace the thermostat and invest in programmable thermostat installation services to receive the convenience and energy-saving benefits of modern thermostats. 

4. The Inside Of Your Thermostat Is Dirty

Modern thermostats rely on sensors to detect your home’s temperature and provide an accurate reading. When these sensors are dirty or damaged, your thermostat can’t properly determine the correct temperature. As a result, a visibly damaged or dirty sensor is a sign you have an inaccurate thermostat. While you can fix a dirty sensor by cleaning the inside of your thermostat and recalibrating it afterward, you’ll need an HVAC professional to repair a damaged sensor.

5. Your Thermostat Is Old

Thermostats usually have a life expectancy of about ten years. If you have an old thermostat past its expected lifespan, it could be providing inaccurate readings. Instead of repairing an old thermostat, it’s often better to replace it with a new model, especially if you don’t have a smart or programmable thermostat. 

With programmable thermostat installation, you can receive all the benefits of the newest temperature-control technology. For example, programmable thermostats give you the opportunity to set your thermostat on a schedule that saves energy while you’re away from home. Many new thermostats also pair with phones and other devices, meaning you can conveniently control your home’s temperature even when you’re away.
