If your air conditioner is humming, it could mean there is an electrical or mechanical problem. Take steps now to verify the issue with your air conditioner.
Possible causes of your cooling system’s humming may include:
A humming sound is evidence that something inside your air conditioner is off and needs attention. Given the causes above, it’s crucial to find where the sound is coming from. Your entire HVAC system is interconnected. The air conditioner requires adequate airflow to operate correctly. Air blows through the air filter, and it’s the blower motor (located inside the furnace) that pushes air through the entire system to heat or cool your home. If the air filter is dirty, or the blower motor malfunctions, that can cause issues with your condenser unit located outside the home.
Resolving the AC humming issue does best with a technician to perform a diagnostic assessment on the whole unit. This work should never be attempted by a homeowner, but only by a certified professional. Your HVAC system has hazardous refrigerants running through it that should be carefully handled only by a professional. Electrical components to your system should never be adjusted by a novice because of the risk of electrocution. Homeowners are better served trusting an HVAC company to examine and repair their system if they notice any odd humming, whirring, or buzzing noises coming from their unit.
If a component like the blower motor is broken, it may be because your furnace is near the end of its lifespan. The blower motor is not a component that needs to be replaced regularly.
