For most drivers, a car without an air conditioner isn’t an option. System breakdowns can make summer driving unbearable, which is why it’s important to recognize early signs that car AC repairs are needed. Below are common symptoms of a failing system and what to do about it.

How to Tell You Need Car AC Repairs

1. Weak Airflow

Poor airflow or the AC only providing brief cool air is the first sign of issues. This means that air is struggling to reach through the vents and is usually due to blockages—an easy problem to resolve.

A car AC repairs professional can look for foliage and debris that may be blocking your system and clear the vents. In more serious cases, seals on the blower house, evaporator core, or damage to the blower hose and ventilation fan may be the case, and you’ll require repairs or replacements.

2. Refrigerant Leaks

Refrigerant is colorless and odorless, which is why you’ll need a professional to check for leaks. If you delay repairs, leaking refrigerant could damage other car parts when combined with moisture.

3. Strange Noises

Strange noises coming from any part of your vehicle are a cause for concern. If you notice a rattling sound when you turn the AC on, there could be debris in the fan.

It may also mean parts are loose or that they aren’t properly lubricated. Catching these early can save you time and trouble on new parts down the road.

4. Burning Smells

No driver wants to smell burning parts when they’re on the road. If you do, turn your AC off and schedule an inspection. The smell may be due to wiring in the system’s compressor burning out.

This damage prevents your AC from functioning and will only worsen with time. When caught early, a technician may only need to replace the wires.
