The thermostat acts as the brain of your HVAC system. Without a thermostat, even the best heating and cooling equipment in the world will do you no good. At Big Bear Air, we offer expert thermostat installation and repair services to clients in Frisco, TX and the surrounding areas. Whether your old thermostat needs to be repaired or you simply want a new model installed, make Big Bear Air your first call.


In general, thermostats are extremely reliable. For many homeowners, this is a piece of equipment that will require little to no maintenance for many years. Still, problems can occur. Here are some helpful warning signs of thermostat failure:

  • Temperature feels wrong. After you have lived in a home for a while, you get to know what certain temperatures feel like in that space. For example, if you have your thermostat set to cool the home to 72° in the summer, you are likely familiar with what 72° feels like when you walk in after a hot day in the sun. But what if your thermostat is reading 72° despite it feeling much warmer in the house? You may have a broken thermostat that will either need to be repaired or replaced.
  • Wild temperature swings. When working properly, a thermostat will guide your HVAC system to control the temperature in your home nicely, making gradual adjustments as necessary. If your thermostat is malfunctioning, however, you might find that the temperature in your home goes up and down frequently throughout the day for no reason. This is not only frustrating from a comfort perspective, but it will also lead to higher utility bills.
  • Frequent off/on cycles. An HVAC system is supposed to work through a full cycle when it is heating or cooling a space. If you notice that you hear your system kicking on and turning off again quickly, something may be wrong.

Don’t wait around if you notice problems with your thermostat. Bring in the experts from Big Bear Air to diagnose and correct the issue.


Even if your current thermostat is functioning properly, an upgrade is certainly worth consideration. Modern thermostats come with many more functions than models that were on the market just 10 years ago. Today’s smart thermostats, for instance, can be controlled via an app, meaning you can adjust your system even when you aren’t at home. These new models are extremely convenient, flexible, and accurate—and they come with a modest price tag.


Replacing your thermostat can dramatically improve the way your HVAC system performs each day. Call Big Bear Air today for thermostat installation and repair today. We are excited to serve you!
