Air conditioner making grinding noise — 3 common causes

If your air conditioner is making a grinding noise, there are several potential causes.

Some of the potential causes of the grinding noise in your AC include:

  • Faulty motor bearings
  • Compromised compressor
  • Issues caused by air conditioner fan making grinding noise

Cause #1 — Faulty motor bearings

The most common cause is a faulty motor bearing. This can be caused by a lack of lubrication, dirt buildup, or simply age.


Cause #2 — Compromised compressor

Another possibility is a problem with the compressor. The compressor is responsible for moving refrigerant throughout the system, and if it starts to fail, it can make a grinding noise.


Cause #3 — Fan blades

It’s also possible that the fan blades are coming into contact with something inside the unit. This could be due to loose nuts or bolts, or it could be a sign that the fan blade itself is damaged.

If you’re not sure what’s causing the noise, it’s best to have a professional take a look. Otherwise, you run the risk of causing further damage to your air conditioner.


Why it’s important to contact a professional as soon as you notice the grinding noise in your AC unit

If your air conditioner is making grinding noise on a regular basis, it’s important to contact a professional as soon as possible.

The noise is likely caused by a variety of issues (some simple, others requiring professional repairs), and if they’re not fixed, it can lead to more severe problems. If left unchecked, the compressor can overheat and cause damage to the AC unit. Ignoring the problem will only make it worse, and it could eventually lead to a total AC failure.

In addition, a grinding noise is often an indication that your AC unit is working harder than it should.

This means that it’s using more energy, which will end up costing you more money on your utility bills.

In some cases, it can even lead to a fire. So if you hear the grinding noise coming from your AC unit, don’t ignore it. Make sure that you call a professional and get it fixed before it’s too late.


How the professionals will diagnose and fix the grinding noise in your AC unit

The best HVAC technicians will be able to diagnose and fix the problem in no time. Here’s what they’ll do:

First, they’ll take a look at the outside unit of your AC unit. They’ll check for any visible damage, such as bent fan blades or a broken compressor. If they find any damage, they’ll replace the damaged parts.

Next, they’ll move on to the inside unit of your AC unit. They’ll check the evaporator coils and make sure they’re clean and free of debris. If the coils are dirty, they’ll clean them. if they’re damaged, they’ll replace them.

Finally, they’ll check the refrigerant levels in your AC unit. If the levels are low, they’ll recharge the system. If the levels are too high, they’ll bleed off some of the refrigerant.

Once they’ve completed all these steps, the professionals will be able to figure out what was causing that terrible grinding noise in your AC unit. So don’t despair if you hear it – just pick up the phone and call for help!


Air conditioner making grinding noise: 5 useful tips

Feel free to use these tried-and-true AC tips if you want to ensure that your unit runs silently:

  • Check the blower wheel for dirt or debris. If the wheel is dirty, it can cause the unit to make grinding noises.
  • Inspect the condenser coils. If the coils are bent or damaged, they can also cause grinding noises.
  • Lubricate the moving parts of the AC unit. This will help to prevent noise-causing friction.
  • Tighten any loose screws or bolts. This will help to reduce vibrations and ultimately prevent grinding noises.
  • Adjust the fan speed. If the fan is set to a high speed, it can cause the unit to vibrate and make noise. Try setting it to a lower speed instead.
