A home HVAC system has three primary sections. One is the air duct systems, the second is the air conditioning or cooling system and the third is the heating system. With spring we will begin to rely on our cooling system to help maintain a comfortable indoor temperature. The air conditioning system puts a lot of strain on the fan motor which is used to push the cool air throughout the home. When the fan motor fails the entire home cooling system suffers. Often a fan motor will give warning signs that is is failing. To ensure your home stays cool and summer along it is important to have the fan motor repaired or replaced before complete failure. Hal Mechanical will share what symptoms to watch for in a failing fan motor.
Fan Motor Making Loud Noise
The fan motor is running more loudly. A classic sign or symptom that the fan motor is wearing down or failing is when the motor develop loud noises while it active. In some cases the cause of the noise is minor., Occasionally debris may get caught up in the fan or a few screws or bolt came loose that need to be tighten. You can check for obstructions or loose component by remove the outdoor unit cover, make sure the unit is turned and no power is running to the unit before your remove the cover. Check for any obvious causes of the noise.
Weak Air Flow from Vents in House
Your air conditioner should circulate air properly. Another sign to watch for is when the air conditioner is running but has poor air circulation, or the air flow is weak. The fan motor is the component the blows the air through the home. When the motor begins to wear down or fail the air flow may seem weak and the air conditioner may be forced to run longer. You may even notice that your power bill increased, this is because the air conditioner is running longer to cool the home. If you notice an increase on your bill or the air flow seem weak or it take longer to cool the home contact an HVAC technician.
Air Conditioner Fan Motor Turns Off Suddenly
When the fan motor begins to fail you may also notice the air conditioner unit kicks on and suddenly shuts off. Or the air conditioner may turn off before the temperatures dropped. You can check the thermostat, if the temperature is higher than the designated setting then the air conditioner unit shut down prematurely. Their may be a loose electrical connection to the fan motor. You can remove the cover of the outdoor unit and check the electrical connection. Again it is essential that the power supply of the unit is shut off, to ensure safety the unit must have no power. If you not familiar with electrical connections or air conditioning systems, contact an HVAC technician.
