Goodman Air Conditioner Noise [How to Fix]

Are you having trouble with a Goodman air conditioner noise? This article details how to fix noises from your Goodman air conditioner in a permanent manner.

Are Goodman Air Conditioners Noisy?

Goodman air conditioners are not noisy, though you may notice a little noise when the environment is quiet. The sound a Goodman air conditioner makes also depends on the size and type. To begin, the sound of the AC unit turning on and going off may be loud. Also, single-staged units are usually noisier than other, more efficient types.

Single-staged air conditioning units make noise, especially if the weather is hot. They tend to turn on full-blast, and that process creates noise. But a two-staged air conditioning unit may generate less noise because it is designed with high and low-speed options. These options mean the unit turns on and off less frequently, thereby reducing the sound of the ON/OFF process, making the unit less noisy.

In other words, the size and type of Goodman air conditioner you own will determine the amount of noise it makes. However, if you notice a considerable increase in the noise, something has gone internally wrong in the unit, and it is best to find a fix.

Goodman Air Conditioner Making Noise – Solved

A dirty air filter, imbalance, compressor issues, dirty condenser coils, bearings scraping against each other, and loose internal parts are some of the causes of a noisy Goodman air conditioner. Replace the air filter or wash it if it is dirty and not too old to need a replacement. Check the condenser to ensure the coils are clean; dirty coils stop the free flow of hot air from the unit, causing problems.

Other things to check if you notice Goodman air conditioner noise are:

1. Compressor

A faulty compressor will generate noise, so it is best to check the motor when the unit becomes too noisy. It may not be a job you can do as a DIY project, and for safety reasons for both you and the air conditioning unit, have a professional examine the compressor. That way, you will know whether or not to replace it.

2. Blower Motor

The blades on the blower may be rubbing against the blower housing, generating the noise you hear in the process. The motor of the blower may also have worn bearings, which means the motor needs a replacement. Begin with the blades; ensure they are fixed correctly and are not rubbing against the housing. If they are, try straightening and adjusting them away from the body. But if they are not the source of the noise, replace the motor of the blower.

3. Dual Shaft fan Motor

The bearings of the motor may be worn, causing a loud noise as they scrape against the motor. Typically, they have lubrication that does not need external topping; it is a factory design. However, constant use will cause wear and tear, wearing the lubrication down, hence the noise. Replace the motor of the fan if you notice the bearings are not in good form anymore.

4. Blower Wheel

The blower has a wheel that fixes permanently to the shaft of the blower motor. If it becomes loose, it will wobble on the shaft as the unit operates, creating noise. Therefore, check the wheel; try fixing it in place and tightening the holding screw if it is loose. If that does not work, replace the wheel.

Contact an HVAC professional if none of the above fixes works and your air conditioner is still noisy.

Goodman Air Conditioner Making a Clicking Noise – Quick Fix

A loose or broken fan blade can cause your Goodman air conditioner to make clicking noises. Check the fans in the unit to ensure none of the blades is loose or broken. If loose, tighten it in place and ensure it is not bent. But if broken or even bent, replace the blade.

You can also check the thermostat to ensure it is not stuck or damaged. A defective thermostat tends to generate a clicking noise, much like that from the start relay in a refrigerator when it is faulty. You may have to replace the thermostat if it is no longer working.

Another part to check is the capacitor. It works like the start relay in a refrigerator by storing current and providing a power boost for the compressor and a few parts to run. If it becomes defective, it may cause the compressor to click on and off as it tries and fails to start. Replace the capacitor if it is not in good working condition.

Dirt in the outside condenser unit can cause a clicking noise. Clean the unit and remove debris that may be hanging in it. Then, check to see if there are loose bolts to tighten. They may be causing the noise you hear, especially if the noise is coming from the outside unit.

It is crucial that you do not ignore the sound of clicking coming from your air conditioner. Find the source of the noise and permanently fix it if you want to prolong the life of the cooling unit.

Goodman Air Conditioner Buzzing – What to Do

Do the following if your Goodman air conditioner is buzzing:

1. Check the Evaporator Coil

When the cooling or evaporator coil freezes, it tends to cause the air conditioner to buzz. So, check the coil to see whether or not it is frozen. Disconnect the air conditioner from electric power and allow the coil to thaw before reconnecting it. Then, find the reason for the frozen coil.

A refrigerant leak is likely to lead to coil freezing. So, wait a few days to see if the coil freezes again after thawing it. If it does, the problem may come from a leak in the sealed system. Hiring a professional to check and fix the issue is of utmost importance.

2. Check the Condenser Fan

Take a look at the blower in the inside unit to see if it is working. If it is but the condenser fan is not, the motor may be faulty. This will cause the compressor to buzz due to the buildup of heat in the outside unit. Disconnect the air conditioner from electric power and try checking the fan yourself.

If there is dirt around the blades, clear it and clean the blades. Ensure nothing is obstructing their free movement. Then, check the motor to see if it is working. You may want to replace the motor or the entire fan if nothing is working.

3. Check Internal Components

Loose components inside the air conditioner can cause it to make a buzzing noise. Check screws and bolts to ensure they are tightly secured. If you are unsure what to check, use the services of a professional.

4. Check the Compressor

The primary source of buzzing noise is the compressor. But a handful of factors can contribute to the noise. One of them is lack of balance. Check the isolation foot to determine whether or not it has deteriorated. The foot is where the compressor sits to ensure it has balance. But if the foot is broken or worn, the compressor becomes unbalanced, which may lead it to create noise. You may have to replace it.

However, when nothing else seems to stop the noise, the compressor itself may be malfunctioning. The problem may be electrical, but you may have no way of determining it without professional help. Therefore, hire an HVAC technician to check the compressor and recommend a permanent fix.

Note: It may be more cost-efficient to replace the entire condenser unit if the compressor is malfunctioning. The reason is that compressors are usually expensive, without adding the technician’s pay.


Find a way to fix a Goodman air conditioner noise. You can opt for a sound blanket to mask the noise, especially if it originates from the compressor. However, it is best to find a permanent solution if the noise is from a component so that it does not cause long-term damage to the air conditioner. A sound blanket can only do so much.
