You survived the winter at last! It’s almost summertime, the ideal time of year to drive. A pleasant, sunny day even makes your everyday commute a little bit better. Following are the 5 main reasons why your car ac blowing hot air.
1. Leakage of Refrigerant
A refrigerant leak is frequently the cause of a car air conditioner spewing hot air. A liquid called refrigerant flows through the A/C system in your automobile, swelling and contracting to remove heat and moisture from the inside. Incorrect refrigerant levels will cause all other A/C components to malfunction.
An outdated hose or an evaporator that is rusty or perforated might also create a leak. However, don’t expect to find a refrigerant leak quickly. You likely won’t see a puddle of liquid under or inside your car. That’s because antifreeze evaporates on contact with the air, unlike motor oil and other vital automotive fluids. Sometimes, if you’re lucky, you might see an oily residue right where the leak is happening.
2. Broken Fans for Cooling | Car Ac Blowing Hot Air
An essential component of your car’s ventilation system is a pair of cooling fans. Their function is to aid in the refrigerant fluid’s heat removal. The refrigerant will not be sufficiently cooled if either of them cracks or sustains other damage (typically from flying road debris), and before you realize it, your air conditioner may start to blast warm air into the cabin of your car.
SOLUTION: There is no way to fix a damaged cooling fan. Replace it at a trustworthy auto body shop.
3. Defective Compressor
It is the component that powers your car’s air conditioning system. It usually powers the movement of refrigerant throughout the system. If this part has problems, the antifreeze will not be in a position to reach the condenser for cooling.
After extended periods of inactivity, such as long winters when A/C isn’t required, compressor problems frequently arise. But many modern cars activate the condenser under the defrost setting, keeping it running all year round, to avoid this.
4. Issues Pertaining to the Electrical System
The air-conditioning system of the automobile is an electric system: in fact, the most common cause of heated air blown out by it is an electrical problem. Anything from wiring being screwed to blown fuses, and innumerable things going wrong electrically, will lead to a situation where one of the many fuses, relays, or switches in the whole setup can go bad, the whole electrical system brings down, and then it would start spewing hot air.
Visit your neighborhood Tires Plus if any of these problems are the reason your automobile is blowing hot air. We will accurately and thoroughly inspect your air conditioner. We will outline the urgent needs and the things that can wait so you can make the choice. You are in control at Tires Plus, after all. Ensure that it’s an awesome one.
SOLUTION: You should have the electrical system inspected by a reputable mechanic due to its intricacy.
5. Filter for Unclean Air | Car Ac Blowing Hot Air
There are certain car types and makes that have cabin air filters installed. Much like your home HVAC filter, this car air filter is full of dust and other particulate matter with time, which requires periodic changing. Not only will a dirty air filter cause reduced air intake and poor airflow, but it can also transfer unpleasant, sometimes harmful dusty and musty smells inside your car.
In addition to heated air escaping from your vents, musty odors or excessively loud AC noises are further indicators that your cabin air filter may be obstructed. Additionally, you can experience jerking or stuttering while your automobile accelerates.
Solution: Purchasing a new filter and changing it on your own is an option; the owner’s handbook will specify how frequently it should be done. Or, if you’d rather, have a professional auto tune-up including changing the cabin filter.
FAQs of Car Ac Blowing Hot Air
How to fix car AC not blowing cold air?
First, see if there is any low refrigerant and top it off if needed. Verify that the condenser and compressor are in good working order by inspecting them. If these components are functioning properly, an electrical issue or system leakage may be the cause of the issue.
Why does my car AC start with cold air then hot air?
The problem could be diagnosed to a low charge, a failed compressor clutch, a pressure problem in the AC system, a random electrical issue, or even an expansion valve malfunction.
