What Is a Thermostat?
A thermostat is a device that regulates the temperature within a space, such as a home or office. Its purpose is to help maintain a desired temperature within a given space by controlling the building’s heating and cooling systems. By setting a specific temperature, the thermostat ensures the environment remains comfortable and energy-efficient.
How Does a Thermostat Work?
A thermostat works by sensing the ambient temperature and comparing it to the desired setting. When the temperature in the space is higher or lower than the desired temperature, the thermostat signals for the cooling or heating system to activate. Once the desired temperature is reached, the thermostat instructs the system to shut off. This helps in maintaining a consistent and comfortable environment within a home or business.

What Is a Smart Thermostat?
If you’re in the market for a new thermostat, you may be wondering, “What is a smart thermostat, and is it worth it?” A smart thermostat is an advanced version of a traditional thermostat that can be controlled remotely via a smartphone or other internet-connected devices. It offers benefits such as energy savings through optimized heating and cooling schedules, learning user preferences over time, and providing detailed energy usage reports.
According to Energy Star, smart thermostats can help you save 8% on your energy bills. If you’re interested in a smart thermostat or other home automation services in Tyler, TX, contact us at Lex Air East Texas today.

Why Is My Thermostat Not Working?
If your thermostat doesn’t seem to be working correctly, there are a few common issues that could be at play. Common causes may include dead batteries, loose or disconnected wiring, or a tripped circuit breaker. Other potential issues could be dust accumulation affecting the sensors or the thermostat being improperly calibrated.
It’s also possible that the thermostat itself is faulty and needs replacement or that your cooling and heating system is malfunctioning. A professional HVAC technician can evaluate your thermostat, diagnose the problem, and repair the issue or replace the faulty equipment.
Signs of a Bad Thermostat
Signs of a bad thermostat include:
- Lack of control over HVAC heating or cooling functions
- Inconsistent or incorrect temperature readings
- Unresponsive or blank thermostat display
- Short cycling of the heating or cooling system
- Sudden and unexplained spikes in energy bills
- Unusual noises coming from the thermostat
Thermostat Troubleshooting Tips
If you’re dealing with thermostat issues, you can troubleshoot your thermostat by:
- Checking the batteries in your thermostat
- Checking the sensor in your thermostat
- Checking the wiring connections to your thermostat
- Resetting the thermostat
- Checking the circuit breaker for that area of the building
Check Your Thermostat Sensor
To check your thermostat sensor, first, ensure the thermostat is turned off and open the casing to locate the sensor. Inspect the sensor for any visible dirt or debris, and gently clean it with a soft cloth if needed.
Verify that the sensor is securely in place and not dislodged. You can also compare the thermostat’s temperature reading with an accurate thermometer placed nearby to see if they match. If there’s a significant discrepancy, the sensor may be faulty and require replacement.
Check Your Thermostat Wiring
To check your thermostat wiring, start by turning off the power to your HVAC system to ensure safety. Remove the thermostat cover to expose the wiring terminals. If your thermostat manual has a wiring diagram, use it for reference. Inspect the thermostat wires for any signs of damage, such as fraying or corrosion.
Ensure each wire is securely connected to its corresponding terminal. If any wires are loose or disconnected, reattach them carefully. You can also use a multimeter to test for continuity in the wires, ensuring they are conducting electricity properly. If wiring issues persist, consider consulting a professional technician.
How to Reset Thermostat
To reset your thermostat, first locate the reset button or option in the thermostat’s settings menu. For models with a physical reset button, press and hold it for about 5 to 10 seconds until the display blinks or resets. For digital models, navigate to the settings menu, find the reset option, and follow the prompts to reset the device to its factory settings.
After resetting, you will need to reconfigure your preferred temperature settings and schedules, if you have a programmable or smart thermostat. If you encounter difficulties, consult the user manual for specific instructions related to your thermostat model.
