Like all parts of a car, your AC is susceptible to wear and tear. It is challenging to know whether your cooling system is having a momentary glitch or needs auto air conditioning repair. Look for the signs below to know whether or not your AC is going out.

When It’s Time to Replace Your Car AC

1. No Temperature Change

If the air coming from your vents isn’t maintaining a cold temperature, you may have a weak or damaged air compressor. The role of the compressor is to regulate the refrigerant flow so that the system can churn out cold air. A hot or mild breeze coming from your AC vents is a telltale sign that something is wrong.

2. Strange Noises

A working air conditioner is typically silent. If you hear any banging or rattling noises coming from your air vents, there’s a problem. It could be debris clogging your unit or a more severe issue. Take your car to a shop that specializes in auto air conditioning repair for a checkup.

3. Limited Airflow

If you turn on your AC and little to no air comes from the vents, you may have an issue with your cooling system. It could be a clogged vent or lack of refrigerant, but check with your auto technician to determine if a more significant problem is at play.

4. Interior Water Stains

When you run your AC, expect to see water drain from the bottom of your vehicle. However, if you see no water on the ground but get stains inside your car, you have an issue. Check for these stains under the dashboard or on the front floorboards. The drain on the bottom of your vehicle may be clogged and backing up into your vehicle, which is a symptom of a dying air conditioner.

5. Off-Putting Smells

The air coming into your car should be scentless. If you turn on your cooling system and a foul or unpleasant odor comes out, you could have mold growth in your unit. Because mold can lead to respiratory issues, address this as quickly as possible.
