Like any appliance, your air conditioning system is going to make some noise when it starts or stops a cycle. But when that noise is loud enough to wake up the entire neighborhood, that’s a sign something isn’t right.
If you’re experiencing this troublesome issue in your Quad Cities’ home, contact a reputable HVAC company as soon as possible to troubleshoot the issue and make the appropriate repair. In our most recent blog, the heating and cooling technicians at Schebler Heating and Air discuss some common reasons your AC makes a loud noise when starting and how to fix this issue.
Reasons Why an Air Conditioner Might Make a Loud Noise When Starting a Cycle
There are a few reasons your AC might make a loud noise when it starts a cycle, which we’ll discuss in more detail below.
Debris In the Unit
If you hear a loud clanging or banging noise each time your air conditioner begins a cycle, it might be an indication that debris such as sticks or twigs are inside the unit. If you’re relatively handy, you can take off the air conditioner top to remove the debris.
A banging noise can also be caused by a loose fan that is hitting the side of the unit, or a damaged cage which is causing the blade to hit up against it. You’ll want to have this issue fixed right away to avoid further damage to your AC unit.
A bad compressor can cause a number of problems, including diminished airflow and circuit breaker issues. You can add loud noises to the list, too. If you’re hearing unusual vibrating, rattling or clunking noises when the system turns on, or while it runs a cycle, it could be the fault of the compressor. Compressors usually go bad in older air conditioners and are quite expensive to replace, so your best bet might be to buy a new air conditioner.
If your unit is making clicking noises when it tries to turn on but won’t start, electrical issues could be at play. Electrical problems can cause problems with the AC’s capacitor, compressor or the thermostat. Contact an HVAC provider to inspect and repair the unit.
Fan Motor Issues
If your air conditioner makes a grinding noise when it starts up or during a cycle, it could be an issue with the fan motor. It likely means the fan motor needs lubrication or the fan motor bearings have broken. If the latter is the case, you’ll need to call an HVAC technician to come out and replace the fan motor.
