External Factors
Understanding why your thermostat temperature rises without explanation can be tricky. External factors often play a significant role in this mystery. These factors can impact the accuracy of your thermostat readings. Let’s explore two key external factors that might be affecting your thermostat: weather conditions and drafts and air leaks.
Weather Conditions
Extreme weather can cause your thermostat to act oddly. On hot days, the temperature inside your home may rise. This causes your thermostat to increase the cooling settings. On cold days, the opposite occurs. Your thermostat may increase the heating settings to keep your home warm. These changes can lead to higher energy usage. It’s important to keep an eye on weather forecasts. This can help you anticipate changes in your thermostat’s behavior.
Drafts And Air Leaks
Drafts and air leaks are another common cause of thermostat issues. Cold air entering through gaps can make your thermostat think the home is cooler. This causes it to increase the heating. Warm air leaks can cause the opposite effect. Your thermostat may increase the cooling settings. Sealing gaps around windows and doors can help. This simple step can make your thermostat more accurate. It can also lower your energy bills.
