3 Problems Caused By Dust In Your Furnace

A functional furnace is one of the most important things you can have in your home during the winter months. Keeping your furnace in good condition is essential to the comfort and safety of your home.

Some problems that can interfere with the performance of your furnace are caused by dust.

Dust that accumulates inside your heating system can wreak havoc on your furnace's ability to heat your home. Here are three problems caused by dust that can leave your furnace in need of repair.

1. Heat Exchanger Damage

The heat exchanger is one of the most important components in your furnace. A heat exchanger is a series of coils. As air passes over these coils, it is heated before being distributed throughout your home.

Dust that accumulates on the surface of the heat exchanger can have an insulating effect on the coils. It is harder for the heat exchanger to transfer heat to the air that passes over it when there is a lot of dust. This causes the exchanger to work harder to heat your home, which can result in damage or premature failure.

An experienced HVAC technician will need to be called in to replace a heat exchanger that has been affected by dust accumulation.

2. Ignition Problems

Modern furnaces rely on the ignition of a fuel source to help generate heat. Dust that finds its way into your furnace can settle on many different surfaces. Any dust that settles on the fuel nozzle responsible for feeding fuel into your furnace system can cause the nozzle to become clogged.

A clogged fuel nozzle won't allow any fuel to pass through into the ignition chamber. Without a fuel source, your furnace won't be able to produce any heat.

Only an experienced HVAC technician should clean or replace a clogged fuel nozzle to restore the function of your furnace.

3. Safety Problems

Dust has the potential to create safety problems within your furnace. Dust can settle on the surface of the burners inside the ignition chamber. A layer of dust can cause the burners to burn fuel inefficiently. This leads to a buildup of fuel inside the combustion chamber. Excess fuel poses a serious safety risk.

Even the smallest flame could ignite the excess fuel and cause your furnace to explode. It's best to have a trusted HVAC technician inspect your burners regularly to keep them clean and functioning safely.
