FAQs About A Central Heater Furnace

The furnace is the last part of a central heating system that you want to develop a problem, as it is needed for producing heat. Several parts are located on the inside of a furnace that can prevent the system from producing heat if they are damaged. You can actually prevent major furnace problems from developing by getting occasional care done for it by a trained HVAC technician. 

Don't make the big mistake of allowing minor problems to remain present for a long time, as they can eventually put the furnace out of order. The content below answers questions that you might want to know about if your HVAC system furnace begins to malfunction.

Why is a Furnace Important for Central Heaters?

A furnace is important to a central heater because it contains the vital parts of the system to warm your house up. There are various types of furnaces, but one of the common types that homeowners use runs off of gas. The gas makes contact with fire, so combustion can take place and send heated air into other parts of the system.

If you have an electric heater, there are other parts that work together to produce heat and doesn't require combustion taking place. No matter which type of furnace you own, it is important to keep it in good shape if you want to enjoy your central heater.

Where Does Combustion Take Place?

If your furnace must complete combustion to produce heat, the process happens in the pilot area. If the orifice of the pilot has problems, it is possible that combustion won't be able to complete. For example, dirt in the orifice or a lack of ventilation around the furnace area can interfere with combustion completing. 

You must understand that incomplete combustion is a bigger problem than the furnace simply being unable to produce heat. Incomplete combustion also puts you at risk for being exposed to carbon monoxide and possibly suffering from the harmful symptoms it can cause.

What Is Needed for a Flame to Be Produced?

In a gas furnace, it takes a thermocouple, burner, and a good supply of gas to produce a pilot flame. If you pilot goes out, it is possible that one of those parts has started to malfunction and need a little maintenance. If an insufficient supply of gas becomes an issue, it is likely to be resolved by turning it up. However, leave it to a professional to increase the amount of gas that flows to the furnace.
