4 Signs Your AC Thermostat Is Malfunctioning

Sometimes a malfunctioning thermostat can make you think that your HVAC system is faulty. This is why it’s essential to check the device first before troubleshooting other parts of the system. Here are some signs that you might need a new thermostat in Dripping Springs, TX.

1. Blank or Unreadable Screen

Start by ruling out the most likely problems, such as the screen’s contrast. You can confirm if it’s an issue with the batteries by replacing them with new ones. Note that old batteries can leak and cause corrosion that can damage the device.

Some thermostats will produce a click sound when starting up your HVAC system. If you don’t hear the click, it may be time to seek a replacement.

2. Incorrect Thermostat Settings

You can use an indoor thermometer to check if the thermostat’s reading is accurate. If the thermostat is in a location with drafts and heat, it will not register the correct temperatures.

The settings of your thermostat can increase energy consumption and deteriorate components in your HVAC system. If moving it to a central location does not solve the problem, the device might be faulty. Be sure to speak to a qualified heating installation and replacement professional for further assistance.

3. Erratic Behavior and Changing Configurations

An aging or faulty thermostat will struggle to maintain its settings. It may cause considerable temperature shifts, diminishing your home’s comfort.

A programmable thermostat can also lose its settings, or it may function erratically. You can restart the device by pressing down the reset button. If this fix doesn’t work, schedule a professional evaluation.

4. Unusually High Energy Bills

Your thermostat is essential for maintaining the efficiency of your HVAC system. When it’s faulty, it will force the system to overwork, raising your utility bills.

If the device is old and malfunctioning, consider replacing it with a programmable thermostat. Programmable devices have multiple features that enhance the precision of the system. Call The HVAC Cowboys for dependable heating repair services in Dripping Springs.
