A Brief Guide On How A Furnace Works
Entering the winter means that you need to check out your household insulation as well as heating appliances that will help you reduce the sense of freezing. The idea is to protect your loved ones by finding the best heating system that will protect you for years.
One of the best appliances that you can find for cold winter days and nights is a furnace, preferably a gas furnace. The idea is to understand the working process of the furnace so that you can determine the issues before they happen.
Generally, space heating is one of the biggest energy spenders in U.S. households, which means that you should learn everything about it beforehand.
Of course, you will always need a few air conditioner installation services that are available 24/7 so that you can call them in case of troubleshooting or potential repairs.
The process of understanding your furnace will help you avoid expensive energy bills in the long run. It is advisable to avoid troubleshooting and repairing the furnace system by yourself, but some repairs require a few seconds of work, which is why you can do it alone.
Let’s start from the beginning.
What Is A Furnace?
The furnace includes a system that uses a forced warm-air distribution system or ducted warm-air by using vents or ductwork.
Generally, the primary parts of this particular system include electrical controls, thermostat, heat exchanger, burners, gas valve, ventilation or duct system, and blower.
Keep in mind that as soon as it creates heat, the combustion gases will vent throughout your household by using a flue pipe and venting system.
Gas Valve and Thermostat
The process starts when the furnace gets a signal from thermostat to turn on, depending on your programming beforehand and the temperature you set.
The idea is to activate it by using the numbering system, which means that it will start operating as soon as the temperature falls below the desired temperature you implemented on the thermostat.
The thermostat will send the signal to it, which will cause the gas valve to open and to fire up the burner component, which is commonly beneath the combustion chamber. You should click here to learn everything about what a furnace is in general.
The idea is that thermostat will operate together with the gas valve to regulate the levels of gas that will enter inside of it
If the furnace is not operating while the gas valve is working fine, it means that you should check out the pilot lights.
You should read the user manual and instructions you got within the heating appliance so that you can determine how to relight the pilot light. On the other hand, you can call HVAC professionals to help you with the process as well.
Sometimes, the issues can happen with thermopile or thermocouple, which will allow you to determine whether pilot lights operate or not.
The thermostat is the vital device that will make sure that the valve is not sending too much gas inside the furnace, especially if the pilot lights are faulty.
Heat Will Reach the Heat Exchanger
Remember that the flames from the inside will reach the metal heat exchanger, which will cause the circulation throughout the looped tubes and into the air. This is one of the most critical parts of the system.
If the heat exchanger is not working, you will not notice the changes in temperature. At the same time, it can lead to severe issues if it cracks or develops leaks, which is something you should inspect from time to time.
Remember that a well-maintained and effective heat exchanger is highly essential for the proper working furnace. If it is not working correctly, the combustion gases will not vent safely, which means that they will enter the household and cause severe issues to your family’s safety.
Furnace Safety Tips
- Regular Inspections – It is crucial to conduct regular maintenance and inspections by finding a professional that will tune it up every single fall. You should do it before turning it on for the season, mainly because you can test it for cracks, clean the pilot light, and inspect the vent, among other things.

- Replace the Furnace Filter – Even though it could be problematic, you need to replace it at least once in three months, and we recommend you to set reminders. That way, you will be able to reduce the potential accidents and issues that may lead to severe problems for your family.
