One of the most frequent questions we get, not only from our current customers but from people interested in having a new system installed is how forced air heating from a furnace works. Here is an overview of what furnaces and air handlers do and how they keep your Cleveland home warm throughout the winter.
When your thermostat signals to your furnace that the temperature has dropped far enough that heating is needed, a switch flips in the furnace and the pilot light ignites, sparking the burners which heat up the chamber rapidly. The air in that chamber is transferred by a heat exchanger to air that run through a second chamber outside the first. So, the air comes into contact with the metal of the heat exchange chamber and is heated, then moved to the air handler where it can be distributed.
Most air handlers are directly integrated with the furnace and sometimes they are the same device to reduce energy consumption. Once the air has been heated by your furnace, the air handler’s blower fan will turn on and move the air into the ductwork that transfers it to the vents in the rooms located throughout your home. There are a number of switches and parts involved in the transfer here so if any of them stop working, the air handler may not move the air as efficiently.
A good furnace can work properly and at a high efficiency level for decades without needing replacement and will always be there when the weather outside gets particularly cold. The above is just a quick glimpse at how it works. There are many more working parts involved and if you need maintenance or repairs on yours, it is recommended that you call a Cleveland heating professional right away for service.
