Persistent noise is a major sign there’s something wrong with your air conditioner. Different sounds mean different things. Before homeowners in Germantown, TN, can do anything about it, they must have some idea of what various AC noises mean. Here’s some information about three types of AC noises and what’s likely to cause them:
Hissing
This is one of the clearest signs that your air conditioner is leaking refrigerant. The sound happens when refrigerant escapes out of holes in your AC system’s refrigerant lines.
Refrigerant is highly toxic and can damage your throat, lungs, nervous system and other crucial body parts if you inhale it. If you hear this noise and can smell chlorine in the air, evacuate your home and ask HVAC service technicians to come and address the problem. They will stop the leak and replace the refrigerant you’ve lost.
Banging
Aggressive banging sounds typically suggest that either some kind of part has come loose inside your system or that a foreign object has found its way inside of it. The loose part may be a fan blade, piston pin, connecting rod, crankshaft or bolt. The foreign objects in question may be sticks, large stones or blocks of ice.
To make these AC noises stop, your air conditioner will need maintenance. During this appointment, HVAC service technicians will clean out debris and fasten any loose parts.
Buzzing
Buzzing often indicates some sort of electrical issue. Perhaps your AC system’s blower motor has malfunctioned or its motor bearings are in bad shape. Another possibility is that an electrical wire in the system has short-circuited.
A soft buzzing noise isn’t necessarily problematic, but a loud one should alarm you. In addition to the other possibilities we’ve discussed, it may also arise because of debris sitting inside crucial system components.
