Indoor comfort is essential in today’s properties. To this end, home builders are coming up with several elements to boost the look of your indoors and outdoors. Other than this, indoor heating and cooling play a significant role in the comfort of your indoors.

Furnaces are currently the go-to choice for indoor heating and cooling. Their popularity stems from their energy efficiency and ease of use. When most people, however, get furnaces, they assume these are maintenance-free.

This assumption leads most of them to contend with frequent furnace repair sessions for their Salt Lake City Utah property. Other than the high costs of frequent repairs, there is something else an improperly or non-maintained furnace might cause.

This is a deadly furnace fire. According to statistics, furnace fires are currently responsible for over 40% of residential fires. These fires are particularly increased in winter when most people will rely on their furnaces for indoor warmth.

Here are the common causes of furnace fires that can be prevented by routine professional maintenance of your appliance.

Clogged Air Filters

Furnaces have an air filter that ensures the air in your interiors is debris-free and protects your appliance’s internal components from damage by this debris. The air filter should be regularly changed to avert its clogging.

Clogged air filters have a restricted airflow that causes your furnace to struggle in drawing the required air amount into it. When the blower runs for an extended period at high speeds in this instance, it is at risk of overheating. This overheating will, in turn, cause the blower motor to catch fire.

High Gas Pressure

The furnace runs on a precise combination of air and gas for efficient combustion. Safe combustion revolves around the pressure of the gas flowing through a furnace’s chambers. This gas should be regulated appropriately to avert unwanted condensation in the heat exchanger that would cause its corrosion.

Other than corrosion, excess gas pressure will cause the production of excess heat in the furnace. As the furnace has a strict heat limit, an excess of this limit will cause the soot on the heat exchanger’s walls to combust.

Cracked Heat Exchanger

Your furnace’s heat exchanger allows the production of heat into your indoors and encases the toxic gases of combustion. A crack on this component causes the leaking of poisonous gases into your interiors. These are not only flammable but pose significant health risks to a building’s occupants.

The cracks, in this case, arise from the expansion and contraction cycles that contribute to the wear and tear of the heat exchanger.

Crowded Furnaces

A crowded furnace generally arises from the inclusion of too many things near its openings. These materials around the furnace will affect the heat distribution of the furnace and cause a buildup of heat around your appliance.

If flammable, these materials catch fire, and the high temperatures around the furnace contribute to the burning of its flammable components.

Few disasters are as devastating as property fires. Unfortunately, your insurance will not pay if you played a role in the fire’s causation by ignoring the above issues. To this end, a record of professional furnace maintenance will prove essential in indemnifying you.
