Sometimes it feels like magic to turn the dial on your thermostat and have your home instantly get warmer. It’s really great, but it’s definitely not magic. This process is more akin to science fiction than it is magic, because there really is some interesting science happening behind the scenes when you change the thermostat.
We’re firm believers in the fact that knowledge is power. The more you know about your heating system as a whole, the more likely you are to call for help when you detect a problem that shouldn’t be happening. Some issues are simple, like changing a clogged air filter, while others are not and require professional support. For those kinds of problems, you can call Ace Hardware Home Services for expert heating repair in Gastonia, NC.
However, it can’t hurt to learn more about the ins and outs of your heating system. Let’s talk about what’s going on behind the scenes and when there might be a problem.
It Starts With the Thermostat
The whole heating process begins with your thermostat that is hooked up electronically to your heating system. Depending on the system you have, it’s set up with an interface that’s easy to work with and that translates the information you put in to your HVAC system.
For example, if things feel too cold in your home, you can turn up the temperature and it will signal to your heating system to work harder. If you’ve got a smart thermostat, your system can automatically signal to the heating system to turn lower while you’re sleeping to save energy.
Either way, your thermostat should be the first point of the heating process. If it’s not working the way you want it to, then it should be repaired by a professional.
Capacitors, Switches, and Ignition
Once you signal the change in temperature to your thermostat, it will send that signal to the heating system. This is done via a series of switches and capacitors. You might notice a click when your heating system turns on or off, and that’s the capacitor.
The capacitor’s job is to simply turn the system on or off, depending on the temperature threshold set on your thermostat. And, if you’ve got a gas furnace, the ignition (which in modern systems is electronic) will light the gas and start heating your home.
The Heat Exchanger and the Blower Fan
Next, the heat is created and the heat exchanger allows that heat to be exchanged with the breathable indoor air in your home. This stops the fumes of gas combustion from entering your home and endangers your family with carbon monoxide or smoke.
Then, the blower fan simply pushes the heated, clean air into your air duct system.
Air Ducts and Air Vents
Lastly, if you put your hand up to the vent in your room, you’ll feel the heated air coming from it. This is the last step in the process but one of the most vital. If you don’t feel that heat coming from the vents, then there’s something wrong with the process. This could be due to leaks in your air ducts or a problem with your central heating unit.
