What is an HVAC inducer?

What is an HVAC inducer?

A draft inducer is a fan that’s located inside of your furnace near the heat exchanger. By turning on before your furnace ignites its burners, the draft inducer is able to clear out any combustion gases that might be lingering in the heat exchanger from the previous heating cycle.

What does a inducer do?

But what exactly does an inducer motor do? A furnace inducer motor is essentially a motor-driven fan, with an electrical box for power connections and metal housing. Your motor should move air through the furnace and heating vent pipes. The fan gets rid of poisonous gases from the previous heating cycle.

How much does it cost to replace inducer motor?

A replacement draft inducer motor will cost between $500 and $700.

How does an inducer motor work?

The inducer motor turns on and draws combustion air into the furnace. This helps to make sure the gas is burning efficiently. Next, an ignitor will either glow or spark to ignite the gas that starts flowing. This gas ignites into flames while the hot air and obnoxious gases are drawn into the heat exchanger.

Why do inducer motors fail?

Most inducer motors failures are simply attributed to the older age of the furnace. In most cases, the internal bearings wear out and since the unit is a sealed unit, there is no way to repair the original motor. Instead the unit is simply replaced with a new one.

When would you use a draft inducer?

Draft inducers are special fans that are installed in the flue vent connector (or sometimes in the chimney) used to vent a heating boiler or furnace. Most often we see these installed on oil-fired systems at which the technician was unable to obtain sufficient natural draft for proper oil burner operation.

How long does an inducer motor last?

How long does a furnace inducer motor last? The average lifespan of your furnace is typically between 15 and 20 years. However, there are a variety of reasons that could cause your furnace inducer motor to fail before this time.

Why is my inducer motor noise?

A draft inducer (or vent blower) is the most common problem on a gas furnace or boiler to cause a noticeable noise. The small motor mounted within the housing can begin to make noise when there is buildup on the wheel (such as sulfur or creosote) or when the motor is close to the end of its usable life.

Why are draft inducer fans necessary in today’s furnaces?

The temperature difference between the air entering the furnace and leaving the furnace. Why are draft inducer fans necessary in today’s furnaces? To separate the combustion gas from the circulating air while transferring heat from the combustion gas to the circulating air.
