How To Fix Car AC Not Blowing Cold Air – 5 Main AC Components

Your vehicle’s AC system consists of several different components that work together to keep you comfortable when you’re driving around Ashburn. While there can be a number of reasons why your vehicle’s AC system isn’t working, here are the top five most common components that could cause your AC system to blow warm air:

Compressor

  • Usage: The compressor moves the refrigerate through the AC system. As refrigerant is moving through your AC system, it removes the hot air from your cabin and blows cold air into your cabin.
  • Fix: With so many little components in your compressor, the best way to fix it if it’s broken is to simply replace it. Use your AC system regularly to ensure your compressor doesn’t fail prematurely.

Refrigerant

  • Usage: Refrigerant is a chemical that removes heat from your vehicle’s cabin and turns it into cool air as it cycles through different components in your vehicle’s AC syste.
  • Fix: While you can recharge your AC system with new refrigerate, refrigerant shouldn’t leak in the first place so simply recharging it doesn’t address the actual issue. You’ll need to have your AC system inspected by a technician to locate the leak.

Condenser

  • Usage:To assist refrigerant with cooling, the condenser circulates the refrigerant to remove heat even quicker.
  • Fix: A failing condenser is usually due to a blockage of debris. One a condenser has becomed damaged, it can’t be repaired and will need to be replaced by a professional.

Cooling Fans

  • Usage: Cooling fans blow hot air from your vehicle out into the atmosphere to assist with cooling your cabin.
  • Fix: Cooling fans usually need to be replaced when they’ve been damaged from road debris. Sometimes a failing cooling fan is also a result of a blown fuse, in which case, you’ll just need to replace the fuse.

Electrical System

  • Usage: The electrical system in many vehicles is responsible for many different components, including the HVAC system.
  • Fix: With such a complex electrical system, damaged wires can be complicated to repair. While it’s certainly possible to repair wires in your electrical system, it’s sometimes easier to have the wiring harness replaced.
