Reasons Why a Central Air Conditioner Might Make a Loud Noise When Starting a Cycle
There are a few reasons your AC might make a loud noise when it starts a cycle, which we’ll discuss in more detail below.
Debris In the Unit
If you hear a loud clanging or banging noise each time your air conditioner begins a cycle, it might be an indication that debris, such as sticks or twigs, is inside the unit. If you’re relatively handy, you can take off the air conditioner top to remove the debris.
Loose Fan
A banging noise can also be caused by a loose fan that is hitting the side of the unit, or a damaged cage which is causing the blade to hit up against it. You’ll want to have this issue fixed right away to avoid further damage to your AC unit.
Compressor Motor
A bad compressor can cause a number of problems, including diminished airflow and circuit breaker issues. You can add loud noises to the list, too. If you’re hearing unusual vibrating, rattling, or clunking noises when the system turns on or while it runs a cycle, it could be the fault of the compressor. Compressors usually go bad in older air conditioners and are quite expensive to replace, so your best bet might be to buy a new air conditioner.
Electrical Problems
If your unit is making clicking noises when it tries to turn on but won’t start, electrical issues could be at play. Electrical problems can cause problems with the AC’s capacitor, compressor, or the thermostat. Contact an HVAC provider to inspect and repair the unit.
Fan Motor Issues
If your air conditioner makes a grinding noise when it starts up or during a cycle, it could be an issue with the fan motor. It likely means the fan motor needs lubrication or the fan motor bearings have broken. If the latter is the case, you’ll need to call an HVAC technician to come out and replace the fan motor.
Do You Need to Repair Your AC? Here’s How to Tell
It’s easy to panic when your air conditioner starts making loud noises. But the question is, how can you know if it’s just a minor hiccup or a more serious problem that requires immediate attention? We recommend calling a professional for AC repairs near you if you notice:
- AC blowing warm or hot air consistently
- Weak or no airflow from vents
- Unusual noises like grinding, banging, or screeching
- Frequent or rapid cycling on and off
- Ice forming on the evaporator coil or refrigerant lines
- Water leaking around the indoor unit
- Burning or electrical smells coming from the system
- Thermostat not responding or reading temperatures incorrectly
- Rising energy bills with no change in usage
- AC failing to maintain the set temperature or struggling during normal conditions
Your comfort should always come first. Need to schedule cooling services near you? Call your trusted local AC repair company for help as soon as your comfort starts to take a dip.
The Importance of Prompt Air Conditioning Services
You want to get the most out of your air conditioner; these systems can be expensive to replace, and you want to do everything possible to ensure your AC unit has as long of a lifespan as possible. This begins with prompt AC repairs as soon as any issues are identified.
Having your air conditioner repaired promptly can provide you with benefits, including:
Extend System Lifespan
We all want our air conditioners to last us as long as possible! Giving your system the repairs it needs, when it needs them, helps prevent excessive wear and tear that can lead to premature breakdowns. When small issues like worn-out components or airflow restrictions are addressed early, your AC doesn’t have to work as hard to keep your home comfortable.
This not only extends the life of your system but also ensures it continues running efficiently for years to come, saving you from the expense of replacing your existing equipment earlier than you might otherwise need to.
Reduce Energy Bills
The harder your air conditioner has to work to produce cool temperatures, the higher your energy bills will climb. Energy efficiency and energy bills go hand-in-hand, which is why getting repairs done quickly is so important. When problems like refrigerant leaks, sensor malfunctions, or airflow restrictions are fixed promptly, your system doesn’t have to overwork itself to keep your home cool.
Addressing repairs as soon as issues arise helps prevent energy waste, keeping your monthly utility costs under control while ensuring your AC runs as efficiently as possible.
Prevent More Costly Problems
The difference in price between repairing a minor issue and a major one can be significant. Having your AC issues repaired quickly can limit the damage and prevent small malfunctions from escalating into expensive breakdowns. A worn-out part, refrigerant leak, or airflow restriction might seem minor at first, but if left unchecked, they can lead to compressor failure or other costly repairs.
Addressing problems early not only saves you money but also reduces the risk of unexpected system failures that could leave you without cooling when you need it most.
Improve Indoor Comfort
What’s better than stepping inside after being in the sweltering Bettendorf heat? Quick AC repairs get your system back in the game quicker, letting you take advantage of a system that’s working properly.
When your AC starts acting more like a heating system, there’s no time to wait. Prompt AC repairs ensure your home stays consistently cool, so you don’t have to deal with hot spots or discomfort.
Maintenance Can Prevent Future AC Problems
It’s true for your car, and it’s true for your HVAC systems! Regular maintenance keeps your air conditioner working properly and resolves minor issues before they grow to become more serious and expensive.
AC maintenance appointments are typically tailored to the exact needs of the system, so tune ups can vary from system to system. During an AC tune up, your skilled technician might provide any of the following services:
- Cleaning or Replacing Air Filters – A clogged or dirty filter can restrict airflow, making your system work harder and reducing efficiency. A clean filter ensures better indoor air quality and optimal performance.
- Checking Refrigerant Levels – Low refrigerant can lead to poor cooling performance and even compressor damage. Your technician will ensure levels are correct and check for any leaks.
- Inspecting and Tightening Electrical Connections – Loose or faulty wiring can lead to system malfunctions or even safety hazards. A tune up includes checking all connections to ensure safe and reliable operation.
- Lubricating Moving Parts – Proper lubrication reduces friction in components like the blower motor and fan, helping prevent wear and tear while improving efficiency.
- Calibrating the Thermostat – An inaccurate thermostat can cause temperature inconsistencies and force your system to run longer than necessary. A technician will ensure your thermostat is properly set and functioning correctly.
When to Call for Emergency AC Repairs
You know you need to schedule air conditioning services, but you’re not sure how urgent the problem is. Can you afford to wait a day or two to get the cooling solutions you need, or is it an emergency that requires a solution right now?
It can be a difficult determination to make on your own. However, we always recommend calling for emergency air conditioning repairs when your home’s temperature starts to rise quickly or when your comfort is affected.
If the AC system has completely stopped working in extreme heat, if you notice electrical issues, or if you’re seeing signs of a refrigerant leak, don’t wait. These situations can escalate quickly and may pose safety risks or cause further damage to your system.
FAQs About Loud Air Conditioners
Why is my cooling system loud?
A loud air conditioner could be due to loose components, a failing motor, debris in the system, or issues with the compressor or fan. If your AC is making unusual noises like banging, buzzing, or rattling, call Schebler Heating and Air to have a professional inspect it.
How can I make my air conditioner quieter?
Routine maintenance, cleaning or replacing air filters, tightening loose parts, and scheduling prompt repairs can all help to reduce AC noise levels.
Should I be able to hear my AC while it runs?
When your AC is running, you might hear a low, consistent humming sound, especially if the AC is located near the room you’re in. If you hear loud bangs, rattles, or screeches, these are signs that your AC is dealing with problems.
How loud is too loud for an AC unit?
Most residential AC units operate between 40-60 decibels, about as loud as a quiet conversation. If your AC is louder than 70 decibels—comparable to a vacuum cleaner—it may indicate mechanical issues or excessive wear.
What should a normal AC sound like?
An air conditioner that is running properly should only make a soft humming or whooshing sound as air flows through the vents.
