Potential Causes For A Force Air Furnace To Have A Lack Of Air Flow

Forced air furnaces are some of the most common types of heating systems for residential properties. While this type of heating system will normally be extremely reliable and durable, there are a handful of issues that could lead to serious performance problems for forced air systems and homeowners need to be aware of them in case they need forced air furnace replacement.

Dirty Filters

The air filters are necessary to clean the air before it is circulated through the heating ducting. Dirty air filters can severely restrict the amount of air that can flow through them. This can lead to the forced air furnace being unable to effectively warm the entire home. Homeowners with pets or those that smoke inside will need to change these filters are a more frequent basis as they will accumulate soot and fur.

Failed Blower

Forcing the air through the ducting with enough power to be able to reach all of the areas of the home will require a powerful motor. If the motor suffers performance problems or malfunctions, there may be some warning signs that this is the source of the lack of air moving through the ducting. In many instances, replacing the compromised motor will be the most effective solution for providing a reliable and permanent repair.

Lack Of Power Or Fuel

In order for the system to warm the air, it will need access to sizable amounts of electricity or fuel. If the energy supply for the furnace is interrupted, it will likely cease to function. Checking the circuit breakers or fuel reserves will allow you to verify if this is the source of the problem. Failed heating elements can be another source of a lack of warmth, but repairing this problem will be more complicated as it may involve disassembling sections of the furnace.

Malfunctioning Thermostat

Homeowners will often assume that the problems with their heating system are stemming from the furnace itself. However, the thermostat can also be a source of performance issues for these systems. Any problems with thermostat will result in performance issues with the system as the thermostat will control when the furnace turns on or off. Over time, a thermostat will suffer deteriorating performance due to its sensors suffering wear or becoming dirty. Thoroughly cleaning a malfunctioning thermostat will correct many issues that may arise with these components. However, if this fails, replacing the thermostat will be a simple upgrade that most homeowners will be able to do without hiring a professional.
