Why is My A/C Blowing Hot Air?

Summer is here and now more than ever it is necessary to have your vehicle's A/C system working at its best. We know how unbearable it can be to get in your car on a hot day only to find that your air conditioning is blowing hot air. You'll still be able to get to your destination with the windows down, but it won't be fun! 

One of the most common air conditioning system problems that we see during the summer is hot air blowing out of the vents when the A/C is turned on. You wait and wait for it to turn cold but it never does. There can be a couple of reasons why this happens, and luckily the professionals here at Haglin Automotive are here to help when A/C service or repair. 

What are some of the causes of an air conditioning system that only blows hot air? 

  • Low refrigerant - refrigerant is an important component within the A/C system and is necessary to the process of cooling the air. Low refrigerant typically indicates a leak somewhere in the system, so topping it off probably will not fix the issue. 
  • Bad condenser - the condenser helps to remove heat from the refrigerant when it comes from the compressor. If there is a blockage somewhere in the condenser or it is broken somewhere, the hot refrigerant will stay hot and your air won't be cold. 
  • Faulty compressor - the compressor is what moves the refrigerant around the system, and if it isn't working properly, the refrigerant doesn't move and therefore your air doesn't cool. 
  • Broken cooling fan - the cooling fan also helps to remove heat from the refrigerant and if it is broken, the air will still be warm as it leaves the vents. 
  • Electrical issues - the system itself runs on many different electrical components, and a problem such as a blown fuse or faulty wiring can cause problems with your A/C. 

All of the causes above are commonly seen when an A/C doesn't blow cold air. If you're currently experiencing this issue, we invite you to the experts here at Haglin Automotive for an A/C service and inspection. Give us a call or stop by today!
