Identifying the Cause of a Loud Indoor Air Conditioner Unit
Step 1: Find the Source of the Sound
First thing is first, you need to locate where the sound of the loud air conditioner is coming from. If it turns out the sound is coming from within the house, it could be indicative of:
- A damaged motor
- Leaking refrigerant
- Lack of servicing on the ductwork
- Ductwork with loose screws
- Some of the same issues mentioned in our article for dealing with a noisy outdoor air conditioner unit
Step 2: Check the Indoor Air Handler
A loud rattling sound could be an indication the that fan has lots of small debris in it. However, you should call the professionals at Galmiche & Sons Heating & Cooling if the loud air conditioner makes these noises:
- A metallic grinding sound such as that of a motor vehicle’s brakes
- A thumping noise that sounds similar to a washing machine that is off balance
- A squealing sound or hissing sound, which is a sign that the refrigerant is leaking
The above sounds could mean that a major failure is imminent, and should be addressed immediately.
Step 3: Check the Attic Ductwork
If the cause of the loud air conditioner is loose screws in the blower or air handler, then you may check and tighten them. Do this only if you are comfortable accessing the indoor unit. If you hear a loud popping noise when the AC engages and stops, then the ductwork may need servicing by a professional and licensed HVAC service technician.
Step 4: Make Use of Dampening Techniques
There are times that the HVAC system is loud by design. If such is the case, the noise from the loud air conditioner can reduced using noise reduction techniques such as adding spray foam in the attic or basement and adding enclosures for the outdoor unit. Consult a professional before implementing any of these techniques as they can damage your unit if done improperly. You may also want to consider a new unit, as newer air conditioner units use much better and quieter technology to cool your home.
