Common Furnace Issues Caused by the Thermostat

Is your furnace acting up recently? Furnaces break down or run into issues ever so often. When this happens home owners have to figure out what happened and get it fixed as soon as possible. Furnaces can have a variety of things go wrong but sometime we overlook that it ends up being the thermostats fault quite often. Your furnace is controlled by your thermostat so if your thermostat is not functioning correctly, your furnace will not function correctly either. There are various issue your thermostat can have that will prevent your furnace from working. First we should know how thermostats work in order to understand more on how they can affect the furnace. Newer thermostats have something called a thermistor in them that senses the heat of the home. It senses the heat by measuring the amount of electrical resistance that increases as ambient heat rises. If your thermostat is faulty it will read this amount wrong and not respond in the correct way. This can leave your home feeling too cool or too warm because your furnace will turn off and on when it shouldn’t. If your thermostat is miscalibrated the professionals at Bartlett Heating and Air can easily recalibrate it for you. Your thermostat is connected to your furnace using five wires. If these wires are crossed, frayed, or broken your furnace and fans will have issues turning on and off. The technicians at Bartlett Heating and Air can rewire your thermostat for you. It is not recommended that you try to fix wiring issues on your own unless you have HVAC training. If you are still using an older thermostat we recommend upgrading to a new digital programmable thermostat. This will save you money on your energy bills because you have have it set to certain temperatures for certain times of the day when no one is home and you don’t need to have it heated or cooled with no one there.
