Common Reasons Why Your AC Is Making Noise And What They Mean

When an air conditioner starts making noise, it is usually a sign that something is wrong and it requires repair. In this blog, we will look at some common noises that can be heard from an air conditioner and what they may indicate. By understanding these noises, you can take the necessary steps to get your air conditioner back to running smoothly. If you reside in Henderson, we recommend seeking help from our professional air conditioner repair technician to ensure proper diagnosis and repair.


If your AC has a buzzing noise, you should look at the condenser unit (the outdoor unit). This noise could be caused by loose electrical connections or parts to faulty capacitors or motors. You should call in our qualified technician to inspect your condenser unit if it’s making this noise.


A hissing sound from your air conditioner typically indicates a gas leak somewhere in the system. This could be due to a thermostat issue, corroded coils, or low refrigerant levels in the system. It is essential to resolve this as soon as possible, as any gas leaks could be dangerous and cause further damage to your system if left unattended for too long.


Screeching noises from an AC indicate great distress within its components, such as blower fans grinding against other metal parts, bearings going wrong, or clogged filters restricting airflow through the system. Suppose you hear screeching coming from your AC. In that case, you should immediately turn it off and contact our HVAC professional, as these issues require specific expertise to fix properly and safely.


Grinding sounds indicate that something within the motor assembly is loose or worn down due to age or increased use over time, such as bearings wearing out or gears slipping against each other due to lack of lubrication or misalignment of parts due to vibration during normal operations. Again, it would help if you had our qualified technician for proper repairs when this happens with your AC unit.


Whining noises coming from an air conditioner are most likely caused by something called “cavitation,” where refrigerant liquid passes through restricted valves and causes high-pitched sounds similar to those produced by boiling water – however, unlike boiling water, no actual steam is present in this case; just restricted flow of liquid refrigerant reaching components designed for more fluidity through them.


Rattling sounds usually mean something has become slightly dislodged inside either the indoor/outdoor unit’s cabinet causing vibrations, due to the constant force of airflow being forced upon it either directly via blowing directly against it (in the case of outdoor units) or indirectly via turbulence created between two pieces of equipment close together like ductwork and registers (in the case of indoor units). After fastening all sides with proper tools, one should quickly identify which components need re-alignments or replacements before they start vibrating so much that they break apart altogether!

To ensure that your air conditioner operates successfully and efficiently, it is crucial to keep it in excellent operating condition. Regular AC replacement can prevent problems and prolong the life of your AC unit. If you’re experiencing any of these noises, don’t hesitate to call our professional for AC repair service in Spring Valley to diagnose and fix the problem.
