How to Know if AC Compressor is not Working?

Our AC started producing a weird sound last year and eventually, its cooling capacity decreased. We hired a professional and learned that the compressor of the unit was at fault, hence hampering the performance of the AC. He mentioned several ways on how to check ac compressor is working or not and one such was to listen to unusual sounds from the AC.

How to Know AC Compressor is not Working?

A faulty compressor can hamper the working process of an AC and even damage the unit. Here are some ways on how to check if split AC compressor is working or not:

• Visual Inspection: 

Look for signs of damage or leaks around the AC compressor unit, such as oil stains or debris accumulation.

• Listen for Noises: 

Turn on the AC and listen for any unusual sounds coming from the compressor, such as grinding or rattling, which could indicate internal issues.

• Feel the Air: 

Place your hand near the vents to check if the air is cool. Lack of cool air despite the AC being on may signal a compressor malfunction.

• Monitor Electrical Consumption:

An increase in electricity usage without a corresponding cooling effect could suggest compressor inefficiency.

• Professional Inspection: 

Consult an HVAC technician for a comprehensive assessment using specialised tools and diagnostics.

These methods must have answered your query: how do I know my AC compressor is not working.

The compressor can be called the most important part of an AC. It is responsible for cooling the room. When our AC stopped working or cooling the room, I called an electrician.

How Can You Tell if Your AC Compressor is Bad?

It is easy to find out whether the AC compressor is working properly or not. Here are some problems you might face if the compressor is not working and this will help you understand how do you know AC compressor is bad:

Check if the air conditioner is blowing warm or room temperature air instead of cold. If its blowing hot air, it might be a compressor issue.

Unusual sounds, such as grinding, squealing, or clunking, may suggest compressor problems. Listen for any abnormal noises when the AC is running and if found, hire a professional to resolve them.

Look for leaks around the compressor or any signs of damage. Leaking refrigerant can lead to compressor failure.

You can use a gauge to measure high and low-pressure readings in the AC system. Abnormal pressure levels may indicate compressor issues.

A malfunctioning compressor can cause electrical issues, leading to a tripped breaker or blown fuse in the AC unit. If you witness such an issue, call an electrician without delay.

So this is how can you tell if your AC compressor is bad. Changing the compressor will require precision so it is better to hire a professional for the purpose. I hope this was helpful in answering your query: how do I know if my AC compressor is bad.
