I had the same thermostat for over twenty years.
It was a plastic dial that served one function. I needed to manually make adjustments to temperature, and it wasn’t overly precise. However, that old thermostat was cheap to purchase, easy to install and never malfunctioned. When I finally decided to purchase a new thermostat I was impressed by the sophistication of technology and shocked by the high price tag. Smart thermostats cost several hundred dollars, and I figured it best to hire a professional to handle the installation. I wanted to be sure the thermostat was compatible with my particular furnace and air conditioner. There were quite a few models with a wide variety of features to choose from. The HVAC contractor was helpful in explaining the benefits of the various models. I invested in a smart thermostat that includes geofencing. I’ve just recently learned what geofencing means. My family’s smartphones are all linked to the new thermostat. The thermostat keeps track of the location of the phones and adjusts the temperature of the home accordingly. When we’re off at work or school and the house is empty, the thermostat knows to conserve energy. It raises or lowers the setting at the perfect time to welcome us home. Plus, the thermostat is aware of what rooms in the home are occupied. There are sensors in each room that react and adapt temperature as we come and go. This technology not only reduces energy use and saves money on heating and cooling costs but also minimizes the workload of the furnace and air conditioner. Because the equipment isn’t required to keep the entire house at the perfect comfort level 24/7, there’s less chance of malfunction and the system should last longer. If there’s a problem with the furnace or air conditioner, the smart thermostat sends me an alert and also notices the HVAC company. Most often, these issues can be resolved remotely.
