Checking the thermostat
One of the most overlooked elements in preparing your furnace for winter is checking the thermostat. This small device plays a significant role in ensuring your heating system operates efficiently. Here are some common mistakes people make in this area and how to avoid them.
Many homeowners forget to test their thermostat before the winter season begins. This can lead to unexpected heating issues during the cold months. To avoid this, include checking your thermostat on your winter prep HVAC checklist. Begin by turning your furnace on and setting the thermostat to your desired temperature. It should respond by initiating the heating cycle. If the furnace doesn’t start, there might be an issue with the thermostat or its connection to the furnace.
Another common mistake is ignoring the thermostat’s batteries. Some thermostats, especially older models, rely on batteries for power. Weak or dead batteries can cause the thermostat to malfunction, leading to inadequate heating or no heat at all. As part of your winter prep, make sure to replace the batteries in your thermostat. This proactive step can save you from dealing with a cold house on a chilly winter night.
Homeowners also often overlook the importance of upgrading their thermostat. Older thermostats may not be as accurate or energy-efficient as newer models. Consider upgrading to a programmable or smart thermostat. These devices allow you to set heating schedules, automatically adjusting the temperature based on your daily routine. This not only enhances comfort but also reduces energy consumption and heating costs.
Additionally, ensure that your thermostat is properly calibrated. Over time, thermostats can become inaccurate, causing them to display the wrong temperature. You can test the calibration by using a separate thermometer to compare the room temperature with what the thermostat displays. If there’s a significant discrepancy, you might need to recalibrate or replace the thermostat.
Lastly, avoid placing furniture or other large items near the thermostat. These objects can obstruct airflow and create a “microclimate” around the thermostat, causing it to read the temperature inaccurately. Make sure the area around your thermostat is clear to ensure it can accurately sense the room temperature and regulate the furnace accordingly.
By paying attention to these common mistakes and following best practices, you’ll ensure that your thermostat is ready for winter, keeping your home warm and comfortable throughout the cold season.
