5 Common Problems for a Forced Air Furnace 5 Common Problems for a Forced Air Furnace

A forced air furnace is a common design for heating many homes. They are popular as they deliver heated air across different rooms in the house. When installed together with a ventilation system, they work effectively to deliver air conditioned air as well. This kind of furnaces can be fueled by gas, electricity or oil.

Unbalanced Air Distribution

Some rooms in the house may become too hot or too cold due to the forced air furnace developing faults. In this case the problem lies with ducts and registers. In case they are not set properly within the furnace’s system, they may malfunction and bring about an unbalanced forced air distribution system. Correct such problems by inspecting the entire furnace regularly. The best way to balance the system is while the furnace is turned on.

Faulty Blower Speed

To improve the flow of warm or cool air in the home, check that the blower speed in set correctly. Carry out regular inspections and make repairs on the device when necessary to keep it in good condition. Depending on the amount of warmth or cold being distributed in through the house, the blower’s speed can be increased or decreased to provide the desired effect. In this case, increase the speed to improve flow of warm air or decrease the speed to make the system operate quietly.

Speed can be increased or decreased by adjusting the pulley on the motor located at the blower.

Faulty Motor

If the motor and the blower pulley get out of place then the furnace may operate noisily. Another indication of such a problem is where by the distributions system functions inefficiently. Correct this problem by placing a carpenter’s square against the outer parts of the motor and blower pulleys to align them.

Furnace Operating Noisily

This is evident through noise in the system such as vibrations. This is a result of air forced through the ducts. If they are not firmly fixed in position then they might vibrate and cause noise. Stop this problem by adding duct hangers to the ducting system. Wrap the hangers around the duct and use nails or screws to fasten and secure it to studs.

Heat Loss

To prevent heat loss in the heating system, consider using insulation. This commonly happens where ducts run through cold basements or open spaces. Avoid this problem by using spiral insulation around the ducting. To fasten it in position, duct tape or strong and firm wires can be used. Another idea is to wrap ducts with aluminum face insulting tape. This helps to prevent loss of heat from the system. It helps to save energy and lower fuel consumption in the furnace.

The best way to avoid problems in a forced air furnace is to check all components regularly and make timely repairs when necessary. Call in an expert once in a while to inspect the entire system. It will help maintain the furnace in good working condition, prevent health and fire hazards, save energy and money.
