Sweating in your car on a hot day can be uncomfortable. If your air conditioner is blowing warm, stale air in the summertime, it can be disheartening. Luckily, your auto repair shop can fix most air conditioner issues quickly. Here are a few common causes as to why your air conditioner may be blowing warm air.

5 Reasons Why Your Air Conditioner Isn’t Working

1. Low Refrigerant Due to a Leak

If your refrigerant is leaking, that may be the cause of why your air conditioner is blowing warm air. Loose connections or old hoses usually cause refrigerant leaks, and it can be difficult to pinpoint the exact location of a leak. If you see an oily-like residue on or around the hose connection, it’s a pretty strong sign your refrigerant is leaking. Your auto repair professional will be able to use a sealant and ensure that your leak is sealed.

2. Blocked Condenser

Your car’s condenser serves one main purpose, which is re-cooling hot refrigerant after it has been compressed. Air flows through the front of your car and is then cooled down by the condenser. Sometimes, debris from the road can get caught in the front of your vehicle and block the condenser. Do a quick visual inspection and remove any debris you may see. 

3. Broken Condenser

If you’ve examined your condenser and can’t see any debris, your air conditioner may be blowing warm air due to a broken condenser. Since it sits at the front of your car, it can be subject to punctures from big items like sticks or rocks. If you can see a large puncture in your condenser, take your vehicle to an auto repair professional to fix the issue.

4. Malfunctioning Cooling Fans

A broken or faulty cooling fan can cause your air conditioner to emit warm air. Issues with cooling fans usually arise due to a burnt-out motor, chipped fan blade, or an electrical issue like a fuse blowout. 

5. Electrical Issues

Electrical issues can cause your car’s air conditioner to stop working. These are the most complex and difficult problems to diagnose, and taking your car to an auto repair shop is usually the only fix. Electrical issues can include poor connections, faulty sensors, or bad wires. If you see any malfunctioning wires in your vehicle, it may be time to schedule your next appointment with your mechanic.
