How a Thermostat Affects an HVAC System

 Think of the thermostat as the brain of your system. It connects to your furnace and tells it when to kick on and when to kick off. This means that when your thermostat is having issues, it affects the whole system in a big way.

One of the most common issues that a malfunctioning thermostat can manifest is short cycling. This means that the furnace doesn't run the full cycling, it instead just kicks on and then shortly turns off. This can be caused by a furnace too big for your house where it pushes out heat too quickly rather than the standard gradual heating. However, if you don't have a new furnace, then short cycling is likely the thermostat's issue. Depending on the malfunction, this could mean your home isn't being heated efficiently. While this is a problem, you should also keep in mind that short cycling is very hard on a furnace. The more a furnace turns on and off, the quicker parts will wear out and need repair.

Sometimes short cycling is caused by miscalibration. This means that the thermostat thinks it is warmer or cooler inside your home than it actually is. Luckily, if it is a calibration issue, this is a rather quick and painless fix for your technician. If short cycling is caused by an actual malfunction, then unfortunately your thermostat may need to be replaced.

Yet, many homeowners should think of a thermostat replacement as an exciting opportunity. Thermostat technology has progressed so much further than just a tiny dial on the wall. If you have gotten into creating an energy efficient home, a thermostat can play a huge part. Consider investing in a smart thermostat that will adjust the temperature for you based on your own unique living habits. Such as turning down the heat while the whole family is out and making sure it is nice and warm when everyone comes back. Give us a call today for more information on upgrading your thermostat!
