An air conditioner that works normally typically makes gentle humming and blowing sounds as it functions. However, when it makes loud and alarming noises, it may need prompt professional repairs. Let’s discuss five worrisome AC noises that your air conditioner in your Chicago, IL, home may make and what they mean.
1. Banging
Banging noises coming from your cooling system are often a sign that there is a broken or malfunctioning part. Parts like the piston pin, connecting rod, crankshaft, rod, and springs can wear out and break over time. Your AC will require professional repairs to fix or replace those broken parts.
2. Clicking
Frequent clicking is another worrisome AC noise you should listen for and act quickly if you hear it. This sound could signal that there is an obstruction in your air conditioner’s fan. Faulty electrical signals or an imbalance can also cause your cooling system to make this noise.
3. Buzzing
Numerous factors can cause your air conditioning system to make buzzing noises. Loose parts, debris in or on the AC system, and electrical issues are just a few that often create this sound. Yearly preventive maintenance helps minimize these problems.
4. Rattling
Rattling can signal that your cooling system is about to break down and may need replacing soon. This noise can be from parts inside the unit wearing out or coming loose. If having an expert tighten parts like the bolts and screws does not resolve this noise, you may need to replace your system.
5. Squealing
Moving parts inside the motor that need lubricating can make squealing sounds as your AC runs. This noise can also be a sign that the motor inside your air conditioner is deteriorating and may need replacement soon.
These five noises coming from your air conditioner in Chicago are often cause for concern. They are signs that your cooling system may need immediate servicing. Contact Besco Air Inc. Heating & Cooling for AC repairs.
