Thermostat Reading the Wrong Temperature?
Do you suspect that the temperature shown on your home thermostat may be inaccurate? You may be surprised to learn that it is a common problem, but it can often be a frustrating issue when the difference is just a few degrees. Here are a few reasons why incorrect thermostat readings happen.
Southern Comfort Mechanical is an award-winning HVAC company that serves residential customers in Lewisville and throughout the surrounding areas. When it comes to inaccurate thermostat readings, poor positioning within the home is the leading cause. Even too much sunlight can affect the measurement.
Whether you have an electromechanical or electronic thermostat, it can have contacts, coils, and metal strips. Dust can build upon those areas and cause the readings to be off. For this reason, it is a good idea to remove the cover every several months or so and gently clean the components.
Some thermostats need to be level. This is most common with the older thermostats that use mercury, but even some newer units are like this. In this case, even bumping into it can knock it off level. Level the unit again, and then, consider upgrading to a product without this disadvantage.
If you have a modern electronic thermostat, the computer chip may fail, at which point the unit has to be replaced. Although less common, it is possible for a sensor component to falter, rather than fail, and give bad readings.
Many modern thermostats are universal and can be set into various modes to support the equipment in the home. But it is possible to mismatch certain thermostats to certain HVAC systems, and one of the potential symptoms of such miscommunication is a bad reading.
