Your car AC not working can be a serious problem, especially if you’re gridlocked in the middle of summer. Your Toyota AC is designed to keep you cool no matter how high the outside temperatures are. An AC can get damaged, but your Toyota auto repair shop in Frederick, MD, will fix it for you. These are some of the signs that your AC isn’t working correctly.

 

Your AC Is Making a Noise

When your AC is running, you shouldn’t hear any noise at all. All you’ll notice is the refreshingly cool air filling the cabin. Noises from the AC inevitably mean that something is going wrong. The AC has numerous parts, and noises tend to suggest that something is loose or damaged.

Car AC Vents in Frederick, MD

Road grit, leaves, and other debris can be sucked into the vents. This debris can partially block the AC and make a noise as it rattles around. A more serious problem is a damaged bearing which will make a squealing or grinding sound. The problem could even be caused by a failed compressor clutch. Our technicians will check the system and fix the problem.

 

Your AC Smells Bad

The cool air blowing through the AC vents has no smell. If, however, you detect a musty or mildewy smell from the vent, this is a sign that your AC needs to be checked right away. This type of smell is caused by bacteria or mold that’s formed and growing in the vent system. Mold produces spores that travel in the air and can make you ill.

 

Under normal conditions, neither bacteria nor mold will live in an AC system. They take time to grow, and the movement of air through the vents makes the AC inhospitable. If, however, your AC hasn’t been used for a long time, or you regularly use the highest AC setting, bacteria and mold can find a home in the vents. High AC settings can produce extra water, which is a breeding ground for bacteria and mold.

 

Your AC Blows Cold Then Hot

If your AC suddenly switches from refreshingly cool to unbearably hot, the most likely cause is a blocked expansion valve. The expansion valve ensures that the right amount of refrigerant reaches the evaporator. If the expansion valve is blocked by debris, refrigerant won’t reach the evaporator.

 

Without this refrigerant, your AC will blow hot air from the outside into your cabin. Our technicians will find the cause of the blockage and fix it. Your AC will start blowing cold air again.
