When the summer heat hits Aurora, a working air conditioner becomes more than just a comfort—it’s a necessity. So when your AC starts making strange noises, especially repetitive clicking sounds, it’s easy to get concerned. These noises often come from something small at first, but if left unaddressed, they can point to system damage or larger electrical issues over time.
Clicking sounds in an AC unit are more than just an annoyance. They can be a red flag that something in the system isn’t working the way it should. Whether it’s happening when the system starts up, while it’s running, or when it shuts down, clicking could mean anything from loose hardware to trouble with the thermostat. It helps to understand what might be going on and what should be done—sooner rather than later.
Common Reasons AC Units Make Clicking Sounds
There is more than one reason your AC might click, and understanding each can help set expectations when reaching out for service. Here are some of the situations that can lead to this kind of noise:
1. Loose or Broken Parts
Clicking can come from parts inside the AC unit that have come loose or broken over time. For example:
– Screws inside the cabinet might need tightening
– The blower fan or outdoor fan blades could be slightly damaged or misaligned
– Motor components could have worn out, especially with heavy use during Aurora’s heat
When parts come loose and shift as the unit runs, they often make rapid, repetitive clicking sounds. If the noise gets louder over time, it may be a sign of increasing wear.
2. Issues With the Thermostat
A faulty thermostat is a common issue that can be easy to overlook. The sound you’re hearing might be the thermostat trying and failing to send signals to the AC unit. This happens more often with older thermostats or those running on low batteries. A thermostat that doesn’t communicate properly with the rest of the system can cause your AC to run in short bursts or not at all, with clicking between each attempt.
3. Electrical Issues
Clicking can also signal a problem with your AC’s electrical system. Relays, capacitors, or wire connections on the control board can wear out, loosen, or corrode. When this happens, the system might attempt to start repeatedly but fail each time, resulting in a clicking pattern. This is not something to put off. Electrical issues can lead to overheating, tripped breakers, or permanent damage. In some cases, the problem can extend beyond your AC system if left unchecked.
4. Debris in the Outdoor Unit
Since the outdoor condenser unit is exposed to the elements, debris like leaves, twigs, or small stones can make their way inside. When the fan activates, these items can interfere with the moving parts and create a clicking or tapping sound. It may seem minor at first, but over time, this can damage the fan or other nearby components. Making sure debris is cleared out with routine cleaning can help avoid this issue altogether.
If you’ve noticed any of these signs or heard new clicking noises, it’s time to investigate. Pinpointing the source of the noise early can help you avoid more significant problems later.
Potential Risks of Ignoring the Clicking Sound
A clicking sound might not seem serious—especially if your AC still cools your home—but delaying action could increase repair costs and risks.
1. System Malfunction
Ignoring this noise can lead to a full system failure. Components that try to operate while damaged or loose will wear out faster. This can lead to overheating, and eventually a complete shutdown of the unit. In peak summer, this outcome can leave your home uncomfortable and in need of urgent servicing.
2. Increased Energy Bills
When an AC system isn’t running correctly, it often works harder to maintain indoor temperatures. This could mean longer cycles or frequent starts and stops. Either way, the added strain increases electricity use, which shows up on your bills over the season. If your home feels less comfortable while your bills keep rising, it’s time to look into the cause.
3. Safety Concerns
There’s also a safety side to consider. Clicking related to electrical faults could lead to shorts or overheating connections. Left alone, this might trip breakers or create problems with other electrical systems in your home. Addressing the issue early reduces these risks and protects the rest of your property from potential electrical problems.
Steps Homeowners Can Take Before Calling a Professional
Before scheduling a visit, there are a few simple checks you can try yourself.
– Check for loose screws or covers. If you’re comfortable examining the unit with the power off, look for any cabinet panels or screws that may have come loose due to vibration. Tightening these may reduce or stop minor noises.
– Inspect the thermostat. Remove the cover to check the battery level and settings. Resetting the thermostat might help correct cycling issues that cause repeated clicking.
– Examine the outdoor unit. Check for any materials like leaves, twigs, or dirt collecting around the fan. If it’s safe to do so, lightly remove anything in or around the visible fan housing.
Only perform these steps if you feel confident and can do so safely. If any of the noise continues, or other symptoms appear—such as the AC blowing warm air or stopping suddenly—pause your efforts and contact a technician.
When to Call for Professional 24-Hour AC Repair in Aurora
If your AC clicks every time it starts but doesn’t run effectively, or if the unit shuts off after just a few minutes, these are signs of a bigger internal issue. You’ll need professional help to test the wiring, motor functions, and any control switches that may have failed.
Other signs that it’s time to reach out:
– The clicking sound grows louder over time
– Clicking is paired with humming or buzzing
– The unit stops before blowing air through the vents
– Clicking occurs with no cooling effect at all
These signals often point to internal breakdowns that can no longer be resolved without professional tools and training. Acting right away will protect your unit from further damage and restore temperature control in your home. Aurora’s heat can be persistent through both days and nights, making quick help essential when your cooling stops working.
Reliable Comfort Starts With Early AC Attention
It’s easy to dismiss an odd noise during a hot day, but acting quickly when you hear clicking can make a real difference. What starts as a loose piece or small relay issue may turn into a complete system breakdown if not corrected.
Taking action when the problem is small saves time and reduces the cost and stress of needing a full repair later. Whether it’s by scheduling regular AC checks or calling for quick attention when something doesn’t sound right, managing problems early helps keep your system in reliable shape.
Even if your AC still runs, clicking sounds should never be ignored. They signal pending trouble that can impact efficiency, safety, and comfort. A fast response not only protects your home from heat but may prevent bigger repairs down the road.
