When your HVAC system fails to keep your Abbeville, LA, home comfortable, the problem may be the thermostat. Your HVAC system’s thermostat is the core of your system, and when it’s faulty, your system will ultimately fail. Here are three signs that your thermostat needs replacing:

HVAC System Turns On and Off Unexpectedly

The primary function of your thermostat is to communicate with your HVAC system. If your HVAC system doesn’t receive prompts from the thermostat, it won’t turn on or off.

This often happens when there’s damage to your thermostat wiring. Similarly, the problem occurs when your thermostat has outlived its usefulness. Thus, when your HVAC system turns off and on unexpectedly, consider replacing the thermostat.

Wrong or Blank Thermostat Readings

Your thermostat should prompt your HVAC system to heat or cool your home according to the temperatures you enter on its screen. If you set lower temperatures but your home still feels hot, it means your thermostat has problems. Possible reasons include a wrongly located thermostat, dusty wires or a blown fuse.

The most common cause of blank or wrong thermostat readings is a faulty thermostat. Start by relocating the thermostat and replacing the fuse. If the unit fails to respond, consider replacing the thermostat.

Energy Bills Have Skyrocketed

When your utility bills rise steeply within a short period, the problem could be a damaged thermostat. Inaccurate thermostat readings force your HVAC to work overtime, which translates to more energy consumption.

The fact that your HVAC system has to cycle multiple times in a day means it consumes more energy than usual. Professional AC repair and installation service technicians can help you diagnose and replace your damaged thermostat.
