How Does a Gas Furnace Work?
It is always good for the homeowner to understand the basics of how your furnace works. On the other hand, this should not be taken as instruction or call for action to do it yourself – leave that to an expert. Your gas furnace has five main components engaged in the heating process: your thermostat, the pilot light, the burner, the heat exchanger and the fan, also known as the blower. As soon as your thermostat detects the temperature in your home is lower than the set temperature it launch the heating process in your gas furnace. The thermostat boosts the ignition process, so the gas valve opens and the pilot light turns on. The pilot ignites the gas burner, which heats up the furnace heat exchanger. Your blower motor then blows air over this heat exchanger. The heated air is then distributed through the house to warm the house and into your ductwork, and the toxic combustion byproducts inside the heat exchanger are vented directly out of your furnace via the flue.
What Are The Most Common Gas Furnace Repairs?
Gas furnaces have some moving parts, which are most vulnerable and need to be well maintained. The most common repairs you may see develop with your system are:
- Cracked heat exchanger– heat exchanger when it is heated up expands, and when it is cooled off contracts and eventually this kind of wear crack it. It is not safe to operate a furnace with a cracked heat exchanger because the toxic gases can escape, so it’s important to have it replaced right away. While heat exchangers are typically manufactured to last between 10 – 20 years, poor maintenance, poor installation, or poor equipment design by the manufacturer can accelerate the process of heat exchanger failure.Problems with the igniter – furnace ignitor is an electric resistant element, much like a cooking element on an electric stove top. When energized it becomes glowing red hot to ignite the gas from the burners. These ignitors are fragile and any break in them will cause issues with your furnace’s pilot.
Issues with the burner – burners can become dirty and rusty over time, which will cause trouble to light and generate heat of your gas furnace.
Modern furnaces in Philadelphia
In any house having an old heating system, there is a high possibility of it being a furnace. Furnaces are one of the earliest heating systems used residentially. In the past, they were operated using wood and coal. Latest designs use propane, electricity or even gas and they are highly efficient. There are some which have AFUE (Annual Fuel Utilization Efficiency) rating of 98%. This implies that they transform 98% of the fuel they use up into heat energy.

How do they work?
How do these furnaces work? Perhaps you have one of the new versions in your residence at the moment heating up the room due to the cold weather. Below are precise descriptions of how these modern furnaces work.
Whichever propellant a furnace makes use of, it bases its working on forced air heating. Heat is transmitted to air by the furnace then blower fans direct the heated air through ducts within the house and out vents. Usually, the air conditioners share the duct system with furnaces. Therefore, you should not worry about additional room for the cooling system.
How a gas furnace works
In a furnace running on gas, a starter light starts up a succession of burners in the combustion cell. The heat created by these burners goes into the heat exchanger which transmits heat into the air and heightens its temperature as dictated by the thermostat. At this moment, the blowers send the air through the duct system. Furnaces operating on propane also use this principle.
How an electric furnace works
On the other hand, electric furnaces use electrical ignition. The ignitions, which have now replaced the gas burners trigger heating elements containing conductive coils. By passing of current through the coils, air is heated and will be moved by the blowers. The heating elements turn on depending on what the thermostat demands.
That is how simple furnaces work though they have many other parts that ensure the whole process runs correctly and does not pose any health risks. It is not recommended for you to attempt fixing a broken or damaged thermostat by yourself, maybe only if you have proper tools and adequate training in repairing heating, ventilation, and air conditioning systems in Philadelphia. No matter what fuel your furnace runs on, you should seek repair services from an expert. (Electric heaters may cause deadly shock and gas furnaces too may bring about poisoning due to carbon monoxide).
