After years of operation, you learn to notice the familiar hum of your air conditioner. When the sounds deviate from the norm, it likely means that your AC is crying out for help. Strange noises can occur before, during, or after the cooling cycle.
Abnormal Noises Your Air Conditioner May Make
One of the most common ways that your AC lets you know that something is wrong is by making strange noises. Some of the common sounds that come from a malfunctioning AC include:
- Squealing
- Whining
- Buzzing
- Rattling
- Clicking
- Whistling
- Hissing
Abnormal sounds from your air conditioner almost always mean a problem with your unit’s function. Over time, wear and tear can cause parts to become loose or damaged and are the most common causes of strange noises during operation.
When strange noises occur, you must take immediate action and seek an inspection to protect your AC components. Trust your system to the capable hands of Rosenberg Plumbing & Air.
Reasons Your Air Conditioner Makes Strange Noises
Responding quickly to strange AC noises is one of the most effective ways to prevent further damage. Even if your AC is not making noises now, it is wise to keep these in mind so you will know when to schedule an inspection with Rosenberg Plumbing & Air.
Squealing Sounds
Squealing sounds from your AC can occur because of damaged motor bearings or worn fan belts. Sometimes, squealing sounds stem from increased compressor pressure because of refrigerant leaks. The unit will usually trip a sensor and shut down if pressure rises.
Whining Sounds
Whining noises frequently occur because of reduced airflow. You should check your AC filter to see if it is clogged. Refrigerant leaks and malfunctioning blowers can also cause these sounds.
Buzzing Noises
Loud buzzing noises from your air conditioner have several causes, including obstructions in the copper lines, failing capacitors, malfunctioning contactors, and isolation feet. Allow our expert technicians at Rosenberg Plumbing & Air to diagnose the problem.
Rattling Noises
The most common cause of rattling noises is loose or worn parts. Commonly loosened components include fans, screws, and cover plates. A full inspection will reveal the problem and allow our technicians to tighten all the moving parts.
You may also notice rattling with your outdoor unit if you have not scheduled regular maintenance appointments. Debris can make its way into the condenser. While this may not seem a big deal, debris can damage your fan components and cause other problems.
Clicking Sounds
A single click when the air conditioner turns on is normal. If you hear multiple clicking sounds, you need an AC inspection. There could be a problem with the thermostat or condenser.
Whistling Sounds
Whistling coming from your air conditioner is abnormal and usually means you have a refrigerant leak. It is essential to rely on professionals to find the source of the leak and get it repaired effectively. Your air conditioner cannot function normally without a precise refrigerant level in the system.
Hissing Noises
Your system may also hiss if it has a refrigerant leak. Refrigerant leaks cause increased pressure in the system, causing it to overheat and malfunction in other ways.
Dangers of Putting Off AC Inspections
One of the most significant risks of putting off an inspection is ongoing damage. Repair issues do not resolve themselves and usually worsen, especially if you continue to operate your air conditioner. Waiting on repairs could lead to increased repair expenses or the need to install a new air conditioner.
