Translation: Could be electrical issues, loose wiring, or even a failing motor. It might also be debris in the outdoor unit—a common issue in Honor where leaves and branches are part of daily life.
This is a sign you should call Moore Mechanical ASAP—not something to ignore until next week.
Translation: Likely a refrigerant leak. Not only does this kill your AC’s performance, it’s dangerous for the environment and illegal to just let it ride.
This one's common in homes around Grand Rapids where older systems are still in play. Our techs are EPA-certified and can handle this fast.
4. Clicking
Sounds like: A nervous pen-clicker, but coming from your walls
Translation: Clicking at startup or shutdown is normal. Constant clicking? That’s usually a faulty relay or control issue.
If you’re hearing this from your system in Novi or Petoskey, let us take a look. Small control issues now can snowball into system-wide problems later.
5. Screeching or Squealing
Sounds like: Brakes on a 1992 minivan
Translation: Often a bad belt or motor bearing. Belts are cheap. Replacing the whole motor? Not so much.
We see this a lot in systems that haven’t had a spring tune-up—especially in high-use homes around Grand Rapids and Traverse City.
6. Gurgling or Bubbling
Sounds like: Your AC is trying to brew coffee
Translation: Could be low refrigerant or air trapped in the lines. Either way, something isn’t flowing the way it should.
This one creeps up slowly—but if you're hearing it in your Honor or Petoskey home, it’s worth checking now before cooling season hits full tilt.
Bottom Line: No Noise Is “Normal” if It’s New
Your AC should hum along quietly, not put on a haunted house soundtrack.
The moment it starts making unfamiliar sounds, that’s your cue to get a professional involved—before the issue becomes expensive.
Trust Moore Mechanical to Shut Down the AC Soundtrack
From Traverse City to Novi, Moore Mechanical has been diagnosing strange HVAC noises across Michigan for nearly three decades. Our techs don’t just “take a look”—we get to the root of the problem and fix it right the first time.
Yes. If your AC is making new, loud, or strange noises, something's not right under the hood. Cooling now doesn't mean it's healthy—it's like driving with the check engine light on and pretending the clunking is "just a phase."
Usually: Loose or broken parts. It might be a busted compressor or a wobbly fan blade. Shut it down and call us—especially if you’re in Traverse City, Novi, or anywhere you don’t want a full system failure.
Buzzing = Electrical problems or debris. Could be a failing motor, bad wiring, or leaves jamming your outdoor unit (shout-out to Honor’s forest vibes). Either way, it’s time to book a service call before you blow a fuse—literally.
Nine times out of ten—yes. That angry-cat sound means refrigerant might be escaping, which kills your system’s cooling and isn’t eco-friendly. Grand Rapids folks with older units—this one’s for you.
Startup clicks = normal. Ongoing clicking = likely a bad relay or control board issue. If it sounds like someone’s clicking a pen inside your walls in Novi or Petoskey, we should take a look.
That’s usually a worn belt or motor bearing. Catch it early, and it’s a cheap fix. Wait too long? You’ll be Googling “AC replacement near me” in Traverse City while sweating through your shirt.
That’s not coffee brewing—it’s low refrigerant or air in the lines. These issues creep up quietly, especially in systems that haven’t been serviced before summer hits. If you’re in Honor or Petoskey and hear this, give us a shout before it gets worse.
Yes. A gentle hum = normal. Anything more than that? It’s time to call Moore Mechanical. If you hear it, don’t ignore it.
Because we don’t just “check it out”—we fix it right:
