Whether you have the thermostat that came with your house or you upgraded to a Nest or another smart thermostat, it is still smart to know how it communicates to the air conditioning unit. This communication is key to your system operating properly and efficiently.
Homes in our area typically have one of two types of thermostats. Most homes today have an electric thermostat, while some older houses still might have an electromechanical thermostat.
Electronic Thermostat: Electronic thermostats work very similarly to a tiny computer. These thermostats use sensors to evaluate the room temperature and whether it needs to be adjusted or not. Newer thermostats, like the Nest, learn your habits in order to automatically adjust the temperatures settings in your home – in summer, for instance, raising the temperature when you leave for the day and lowering it when you typically get home. They may also be able to connect to WiFI, meaning you can control your settings from an app on your phone. Other thermostats are programmable, meaning you can manually set them to certain temperatures at certain times of the day.
Electromechanical Thermostat: Older thermostats are a little trickier. These thermostats usually have a coil or a strip. When there is a change in the temperature, the coil or strip will move. This action causes a small vial that contains mercury to move to the left or the right. Doing so sends a signal that the temperature needs to go up or down.
Why it’s Important to Get AC Tune-ups:
Being in Texas means that the weather is all over the place. Especially in the summer, when outside temperature can reach upwards of 100 degrees, it is essential to make sure that your air conditioner is working correctly. That way you don’t have to suffer through those hot summer days without AC.
We all know it takes energy to keep your home comfortable in the summer. Since energy use is expensive, just like going to the doctor, performing AC check-ups can help catch issues with your system before they’re too big. This task can save you additional money and keep you from further stress.
