What's Causing Annoying Noises From Your AC? Find Out
Since modern air conditioners have components that dampen sound, an unexpectedly loud and unfamiliar noise from your AC can create discomfort in your home. Furthermore, these noises may be accompanied by the unit's reduced operational efficiency. Knowing the cause for such sounds is crucial since they indicate internal issues. Besides, it allows you to seek professional help from your AC repair technician in good time. As a result, you will evade a potential system breakdown and expensive appliance repairs. The following are common AC noises and what they mean.
Clicking Noises
Foreign objects such as small plastics and sticks can dislodge the fan or get entrapped in the fan blades. Eventually, the fan's motion gets obstructed, producing clicking sounds. Moreover, the capacitor may lose charge and not turn on the compressor. This causes the outdoor to run feebly. You should call your technician when you hear clicking sounds. They'll establish the cause of the noise, clear the fan's obstruction, and replace the capacitors with infinite resistance.
Whistling Noises
If your AC appliance is making some whistling noises, there's a possible leak in the ducts. Torn, worn out, and poorly insulated ducts may leak air through the lines. Additionally, if the flow of air is restricted due to an obstruction, pressure will build on the blower motor, and this can lead to whistling noises. Therefore, you should engage your AC expert to perform a system tune-up when the system begins to produce this sound. They will clean and replace the air filters and seal the ducts.
Hissing Noises From Your Appliance
Hissing sound often signals a refrigerant leakage or a leak on the compressor valve. With constant use of the AC, the refrigerant lines can degrade, leading to leakage. Low levels indicate a leak since the refrigerant does not get depleted with use. Furthermore, a leakage in the compressor valves can prompt high-pressure build-up resulting in a hissing noise. To eliminate this annoying sound, you should seek professional AC services to have the leaks in the refrigerant line and compressor valves sealed.
Pulsating Noises
A loud throbbing sound could result from a loosened fan blade or a coil. Moreover, the compressor's vibrations can cause the plastic base to pulsate. Therefore, you should hire an AC technician to tighten the screws holding the fan blade or replace the plastic base with a wooden pad to minimize vibrations.
Since the AC produces sounds in its normal operations, it is imperative to understand unfamiliar sounds. Hiring an air conditioning repair professional to address the issues when the noises come up will lead to improved performance of the AC.
