A split or central air conditioning system can develop problems in the air handler and condenser. The air handler is the unit inside the home, and the condenser is the unit outside the home. Both units contain a fan like component. However, each has its own job and develops different problems. When they wear or break down it helps to understand the two different fan system and determine signs of failure for each. Air Supply Heating & Air Conditioning will help you better know your condenser fan and the air handler’s blower system.
How Do I Know if My Condenser Fan is Bad?
For those with a split air conditioning system you will have two units. The condenser is the unit outside your home on the ground or sometimes on the roof top. The condenser unit has a large fan that you can see on the top of the unit. The condenser’s fan motor works as the cooling system and the heat exchanger. It is responsible for cooling and condensing the gaseous refrigerant and transforming it back to a liquid state. After turning the refrigerant back into a liquid the refrigerant travels through the condenser coils and heads toward the evaporator. Once at the evaporator, the liquid refrigerant will become a gas again. Without an efficient working condenser fan the cooling process can be compromised. When a condenser fan fails it is mostly due to the motor wearing down. However, the fan blade also requires cleaning, lucubrating, and tightening. If the fan isn’t properly maintained, it cannot cool the air and restore the refrigerant back into a liquid. When the fan or its motor develops problems, the home will feel warm and often you can feel warm air blowing through the vent. When the motor begins to fail, you will hear a loud screeching noise coming from the condenser. If you notice any of these signs, turn off the air conditioner and contact an HVAC repair service.
What Can Causes Air Handler Blower Motor to Stop Working?
The unit inside the home is the air handler. The air handler has its own fan like component which is called the blower. The blower has a basic job, and that is to blow the cool air through the air ducts and into the home. The blower not only circulates the cool air during the summer, but also the heated air during winter. The blower runs throughout the entire year and is one of the first components to wear down and will need repair or replacement at some point in the HVAC system’s life. When the blower fails, again it is most likely due to a problem with the motor. The blower motor can wear down, and when it does it will often make a grinding like noise. The blower fan blades can become impacted with dirt and need to be cleaned and lubricated to ensure efficiency. There are different types of blower, and some are belt driven. The belt can stretch out and become loose or break. It is common to need to replace the blower belt. When a blower develops problems you will not feel any air coming from the vents and the home will become warmer. When there is a problem with the blower, turn off the cooling system and contact an HVAC service.
