Why Is My Car AC Blowing Warm Air?

So you’re getting into your car after a summer afternoon in Clermont and turn on the AC. You’re expecting that cool, refreshing air to hit you at any second… only it doesn’t. Instead, you’re hit with warm air and sudden panic, all while you’re researching “Why is my car AC blowing hot air?”. Well, you can stop panicking, cause we’re about to walk you through some of the common causes of car AC repair and what you can do to prevent any future issues!


Why Is My Car Blowing Warm Air? Low/Leaking Refrigerant

Let’s start with the refrigerant, which is essentially the “blood” of your car’s AC system. This chemical cycles through and absorbs heat from your car’s cabin and releases it outside. If you’re low on refrigerant (usually due to a leak), then there won’t be enough to absorb the heat, and your AC ends up blowing hot air back at you. Your Toyota of Clermont technicians can inject a dye to figure out where the leak is and fix it, but if it’s left untreated, you’ll be dealing with costly car AC repairs in the future!


Why Is My Car AC Blowing Warm Air? Dirty Cabin Air Filter

The cabin air filter removes pollen, dust, and debris from the air, which means it’ll get clogged over time. This restricts airflow, which means you’ll feel warmer air coming in from the vents and leaves you questioning, “Why is my car AC blowing warm air?”. This can be avoided by bringing in your Toyota to our Clermont service center for regular maintenance, where our techs recommend replacing your cabin air filter every 12,000-15,000 miles.

Why Is My Car AC Blowing Warm Air? Faulty/Failing Compressor

Another culprit of warm air from your AC is a faulty compressor. Just like how refrigerant is the blood of your car AC system, the compressor is the heart. If it’s not able to circulate the refrigerant, the system can’t cool the air. This can be prevented by running your AC once a month for 10-15 minutes a month to keep everything lubricated. If you hear a loud noise or notice your cold air turning warm after running for a few minutes, this could be the reason why.


Why Is My Car AC Blowing Warm Air? Blocked Condenser

If you’re still asking yourself, “Why is my car AC blowing warm air?”, then it could be an issue with the condenser. The condenser cools down the refrigerant after it’s removed the heat from the car’s interior. Road debris, dirt, or even a car accident can interfere with this component, or it can get too warm to function properly after sitting outside in the sun for too long. This can be an easy car AC repair by clearing off any visible blockages in your car’s grille, and rinsing the condenser with water when you wash your car! 


Why Is My Car AC Blowing Warm Air? Faulty Blower Motor/Fans

The blower motor is responsible for actually pushing the cool air out from the vents. If the motor is weak, broken, or clogged, you’ll get poor airflow. Stop by Toyota of Clermont to have a professional inspection to determine if the motor or fan is the problem!

Why Is My Car AC Blowing Warm Air? Electrical Problems

The final explanation to answer “Why is my car AC blowing warm air?” may be electrical issues! Your Toyota relies on many wires, sensors, relays, and switches to keep you going on the road. If you have a frayed wire, blown fuse, or bad sensor, it can wreck the whole system. This can be caused by the heat or if the engine is overheating, but routine maintenance can help prevent this! This car AC repair needs to be diagnosed by an auto tech before it’s dealt with, so stop by Toyota of Clermont for the experts to check it out.
