Temperatures can soar and dip dramatically in Las Vegas, NV, and the last thing anyone wants is a thermostat that changes randomly. At Simply Cooling, Heating & Plumbing, we often hear from homeowners dealing with this frustrating air conditioning issue. The cause can range from faulty sensors to wiring problems or incorrect settings. Understanding what’s behind the changes can help you get your HVAC system back on track—and maintain a consistently comfortable home environment.
Sensor Malfunctions
A thermostat works by measuring the ambient temperature and signaling the HVAC system to operate accordingly. When the sensor malfunctions, it might lead to incorrect readings, causing the thermostat to change settings seemingly on its own. Factors like dust buildup, electrical interference, or inconsistent airflow can throw off the sensor’s accuracy and ability to adjust appropriately.
Poor Thermostat Placement
When a thermostat is installed in a spot that receives direct sunlight, is near a draft, or close to a heat-producing appliance, it can have a false reading of the home’s actual temperature. It’s crucial to place it in a location that accurately reflects the general environment of the home. Avoid placing it in any area with temperature extremes, including:
- Near Sunlit-Facing Windows.
- Above or Near Vents.
- Close to Heat Sources.
- In Frequent Draft Zones.
- On Exterior-Facing Walls.
- Inside Narrow Hallways.
- Behind Furniture or Curtains.
Low Battery Levels
Sometimes, the solution for a thermostat that keeps changing the temperature might be as simple as replacing the batteries. Thermostats, particularly digital versions, rely on batteries for optimal functioning. A low battery level can result in erratic behavior, including unexpected temperature changes. Replacing your unit’s batteries regularly can prevent these issues.
Clogged Or Dirty Air Filter
When dust and debris clog your air filter, it can disrupt your HVAC system’s performance, preventing it from reaching the set temperature. This strain may cause the thermostat to overcompensate, leading to unexpected changes in your home’s temperature. Replacing the air filter regularly helps ensure consistent performance.
Improper Settings Or Modes
Sometimes, thermostat issues are caused by incorrect settings. Many smart thermostat models include features like eco-mode, which automatically adjust to save energy. While efficient, these settings can cause unexpected temperature changes. Reviewing your manual can help you understand and make an adjustment to maintain consistent comfort.
Wiring Problems
For more persistent thermostat issues, wiring might be the root cause. Loose or frayed wires can disrupt the connection between the thermostat and the HVAC system, leading to unpredictable performance. It’s advisable to have a professional HVAC technician inspect the wiring if you suspect this might be the case.
