Each component in an air conditioner has a role to play. Each component does its part to keep the home cool and comfortable. When one fails, the entire HVAC system suffers. One major component is the blower. The blower plays a major role in the overall cooling cycle. Today, Absolute P&M Services would like to share the role of the blower and what signs to watch for if the blower fails or breaks down.
Function of Blower Motor in Air Conditioner
The blower is a crucial component in an HVAC (Heating, Ventilation, and Air Conditioning) system. Its primary role is to circulate the cool air throughout the home or building. However, the blower does other tasks. Here are all the different tasks the blower achieves during a cooling cycle.
• Circulates Air: The blower circulates air through the system. It does this by drawing the air in from the return air ducts, passing it over the heating (heat exchanger) or cooling elements (evaporator coils). The air is then distributed to the cooled or heated air through the air ducts and then throughout the home.
• Maintains Temperature: By circulating the cooled or heated air, the blower helps maintain a constant temperature throughout the home. By ensuring the air is evenly distributed, it will prevent hot or cold spots from occurring.
• Humidity Control: The blower also contributes to humidity control by circulating air over the evaporator coil. During this process the moisture is condensed from the air and reduces indoor humidity levels. The blower can help improve comfort and prevent mold and mildew from growing.
Signs of Blower Motor Failure
When a blower fails in an HVAC system, it can lead to warm and uncomfortable temperatures in the home and poor efficiency. A failing blower can lead to potential damage to other components in the HVAC system. It is important to detect a blower failure quickly and seek repairs to ensure the longevity of your air conditioning system. Some classic signs of blower failure to watch for are:
• Weak or No Airflow: If you notice little to no airflow coming from your air vents, this is a common sign of an issue with the blower motor, fan, or other accompanying components.
• Odd AC Noises: Strange noises coming from the blower, such as a squealing, grinding, or rattling, often indicates there is a problem. Odd noises from the blower motor could mean damaged parts of the blower such as worn bearings, a loose belt, or damaged fan blades.
• Uneven Cooling: If certain areas of your home or building are not receiving enough cool air, this may be a sign that the blower is not circulating air properly.
• Blower Runs Constantly: If the blower motor is running continuously without turning off, it may be a sign of either a failing motor, a malfunctioning thermostat, or an issue with the control board.
• Increased Energy Bills: A failing blower motor tends to draw more power than usual to maintain enough energy to run. This will often result in a much higher energy bill.
• Overheating or Tripping Breakers: A malfunctioning or failing blower motor can overheat, causing the air conditioning unit to shut down or trip the breakers.
