What’s Causing These 4 AC Noises in Upland, CA?

You need to pay attention if your air conditioner in Upland, CA, makes weird noises. You might have a serious problem with your air conditioner that needs immediate repair. Let’s look at four AC noises and what can cause them.

Clicking

It’s not always bad news when your AC system makes clicking sounds. Many systems make a short clicking sound when they start or stop. But if the clicking never stops, you have a problem.

Constant clicking is often the result of a faulty thermostat. An HVAC comfort advisor can replace or repair your thermostat, usually within an hour or less.

Rattling

Several things can cause your AC system to rattle. For example, the air conditioner can have a loose screw or another loose part tumbling around inside the system or compressor. Things often become loose due to wear and tear or some other malfunction.

Regular HVAC maintenance can help prevent this problem. You’ll spot potential issues and make repairs before any damage occurs.

Humming

You might enjoy humming during your day, but you don’t want to hear your AC sysem doing it. When your air conditioner emits a steady hum, it can mean you have a faulty contactor relay switch.

Hissing

A hissing AC system is never a good sign. You’ll need an HVAC comfort advisor to get to the source of this sound. Anything from a leaky air duct to a faulty expansion valve can cause this problem.

If refrigerant is leaking, you might also hear gurgling along with the hissing. Modern refrigerants are less likely to cause you harm, but some of the older substances are toxic. It’s wise to address this problem as soon as possible.

You should never ignore it when your AC system in Upland, CA, makes weird noises. Contact Metz Air Control to discover what’s wrong with your air conditioner and repair it.
