Could Your AC Problem Be Caused By Your Thermostat?

May 11, 2020

Whenever your AC unit is undergoing some routine maintenance, do not overlook the importance of the thermostat. In fact, the thermostat is one of the most crucial components of your entire cooling system. Essentially, it is the device tasked with controlling the functionality of your AC unit. It determines the room temperature by measuring how hot or cold the surrounding air currents are. From there, it can regulate your indoor temperatures to your desired settings. However, if your thermostat is malfunctioning, the operation of your AC system will be in jeopardy.

Many problems that your cooling unit is suffering from can be linked back to a faulty thermostat. It is, therefore, of vital importance to ensure that this component is always well-calibrated and working at peak condition. The following are AC problems that stem from having a failing thermostat:

1. Short Cycles

If your thermostat is faulty, the compressor of your AC unit is also likely to malfunction. You may find that it turns off unexpectedly and turns on soon after, repeating this process over and over. This is an indication that your thermostat’s sensor is likely failing. In such a case, let our proficient technicians replace your sensor and resolve your issue.

Short cycles can have several negative effects. Some of these include:

  • High electric bills
  • Shortened machine life
  • Poor, uneven cooling
  • Frequent compressor repairs

2. Uneven Cooling

Another thermostat issue that could affect your unit is the problem of incorrect calibration. Your cooling system relies on the thermostat to gauge the temperature of your surroundings before attempting to start the cooling process. If the thermostat is giving off an inaccurate temperature, your AC may end up not cooling your household evenly.

Typically, it will only run for a short while. It will then stop before reaching the desired level of comfort in your home. Allow our qualified and competent technicians to calibrate your thermostat while performing routine AC tune-ups. It is also a good idea to keep your thermostat away from objects that may affect its readings. These include heat sources such as light bulbs.

3. Blower Malfunction

Your thermostat breaking down can also directly affect the functionality of the AC blower. The blower helps to circulate cold air throughout your household. If your unit is running non-stop due to poor thermostat calibration, then the blower fans will also run constantly. This can lead to extra wear and tear. You may find that you need to replace your blower fans frequently.

4. Not Cooling at All

If your AC unit is not emitting any cold air, there could be an issue with the compressor. This may also indicate a problem that stems from the thermostat. Specifically, it may mean that there is a problem with the wiring connecting the thermostat to the compressor. If there’s no wiring issue, our technicians will inspect to see if your thermostat’s batteries are dead. Additionally, our team will test your device to make sure that it cools your indoor environment to the desired temperature setting.

5. Continuous Running

Undercooling is not the only issue that your AC unit may encounter. A faulty thermostat can also greatly impact the energy efficiency of your unit by making it work too hard. If your AC system is running continuously, it may expend more energy than it needs to in order to cool your home. Despite running more, your AC system will also never achieve the desired level of comfort you need. Furthermore, it will also likely lead to more breakdowns and repairs.
