Keep reading to learn how to spot problems with your air conditioning system before it’s too late!
Banging Noises
If your air conditioner is making a banging noise, this indicates a problem with the compressor. This component distributes refrigerant through your HVAC system. The banging sounds start when separate components hit the compressor’s exterior framing. A leak in the system or a worn-out part can cause this.
Screeching Sounds
Screeching noises indicates the motor’s fan failure or a broken engine in the compressor of the condenser system. (outdoor condenser unit).
Humming Noises
A defective contactor relay switch may cause a humming noise inside your air conditioner. This part starts the outdoor condenser unit when it receives cues from your thermostat. If you don’t take care of electrical issues in your system, though, severe damage will occur to your central air conditioning system—and that damage will be expensive to repair.
Buzzing Sounds
A buzzing sound from your outdoor condenser unit may indicate that the fan blades are loose or unbalanced. This noise can also be caused by problems such as faulty outdoor fan motors, dirty condenser coils, and loosely attached components.
Rattling Noises
If you’re hearing mysterious rattling coming from your condenser unit, it’s likely due to some loose sticks or leaves. In more severe cases, the noise may be caused by a damaged electrical contractor in your system.
Clicking Sounds
If you’re only hearing a clicking noise at the beginning or end of your cooling cycles, that’s normal. However, if you’re attending a continuous clicking sound, this could indicate that your thermostat is malfunctioning.
Hissing Noises
A hissing noise from your air conditioner indicates a leak in your house’s air ducts. It could also mean the expansion valve might malfunction, or the filter might not be compatible with your system.
Bubbling Sounds
When the air gets trapped in the pipes, you’ll hear a bubbling sound from your unit. The issue is that the refrigerant and water are not mixing correctly due to a blockage in the line.
