How To Stop Your AC Appliance From Making Loud Noises While Starting Up

If your AC is making exceptionally loud noises, an element could be malfunctioning and therefore needs attention. Neglecting this warning sign could adversely affect the system as other components may also suffer damage due to the defective element causing the unit to be inefficient and inoperable. Therefore, when you notice loud noises when starting your AC, contact a same-day appliance repair professional to address the issue immediately. Below are some types of loud noises and ways in which you can stop them from happening while starting your AC:

Clanging and Banging

If debris collects in the compressor, your AC might produce a loud banging sound. Additionally, if the screws holding the fan become loose, the fan may rub against the AC housing, causing a banging sound. Therefore, you should hire an appliance repair specialist to diagnose the cause accurately, tighten the components, and clear debris that may obstruct the fan's operation.

Screeching and Squealing

A screeching sound from your AC could indicate that the fan's motor bearings are worn out. Moreover, a lack of enough lubricant may cause them to grind on other metal components, producing a squeal. Furthermore, the belt attaching the fan to the motor could have slipped out of position and possibly worn out, generating an unpleasant sound. An AC appliance repair professional will assess the AC and ascertain the cause of the squealing sound. Depending on their findings, they may need to lubricate and replace the bearings, replace the fan belt, or both.

Pulsating Noises

An AC produces a moderate pulsating noise during its normal operation. However, if the throbbing heightens into a loud noise, a fan blade could have partially detached and may be spinning in an irregular motion colliding with the AC's cage. Moreover, the motion of the compressor can cause the appliance to vibrate along with the plastic base that supports your AC appliance. To resolve this, your AC appliance repair technician may need to tighten the screws supporting the fan blade and replace the plastic base with a wooden pad to minimize vibrations.

Hissing Sounds

A hissing sound in your AC could signify a leaking refrigerant. Appliance's refrigerant lines deteriorate with constant use, resulting in the refrigerant leaking in the condenser coils. Furthermore, high pressure can accumulate in the compressor due to the cooling medium being at an incorrect temperature. Therefore, you need to hire an AC specialist to solder and patch the cracked coil and replace it if it is irreparable. They also replace worn-out compressor rings and clean the condenser to cool the refrigerant sufficiently.

It is crucial that you take note of any loud noises that your air cooling appliance makes when you turn it on. Hiring a same-day appliance repair technician to address them will ensure that the unit functions optimally and prevent the entire system from breaking down.
