Conclusion
If your AC is whistling, it could be because the unit is too big for the space, the air filter is dirty, or the blower wheel is damaged. If the unit is too big, it will cycle on and off too frequently and won’t be able to maintain a consistent temperature. A dirty air filter can restrict air flow, causing the unit to work harder and making it more likely to overheat.
A damaged blower wheel can also cause the unit to overheat and will need to be replaced.
