How Does a Gas Furnace Heat My Home?

Gas furnaces have proven to be reliable source of heat for many households, and in towns like Skokie IL, gas furnace repair services deal with the same basic technology used for decades. The components improve, the systems become more efficient, but gas furnaces are so prevalent because the fundamentals they use to heat your home remain unchanged. “How does a gas furnace heat my home?” you may be asking. The answers reveal much not just about how home heating works, but what happens when your gas furnace breaks down.

Most gas furnaces used “forced air” systems, which bear a certain resemblance to air conditioning systems (and which explain why your furnace may use the same system of ducts that your air conditioning system does). It starts with the thermostat, which detects when the temperature in your home drops below your prescribed level. That triggers the flow of gas into a combustion chamber, which is then lit by an igniter or a pilot light. The burning gas heats up the air very quickly. A fan or blower then moves the air into your duct system and throughout your home, warming the temperature until it’s comfortable.

It’s an effective system, though it requires a number of components to work in sync. When one of them fails, the entire system is compromised. Many times, the furnace will shut off when a problem arises, since the gas it uses to generate heat can become dangerous if it leaks out of the system. In other cases, such as an overload of the fan motor, the system will shut down to prevent further damage to other components.
