The procedure of removing hot air and moisture from the air necessitates several different parts. Particular of these parts responsible for this procedure include:

  • Refrigerant
  • Compressor & condenser
  • Evaporator

Once it comes to crunchy, cold air flowing finished your vents, all these parts obligation be working at 100%.

Five reason name why your car ac blowing hot air

  • Run Depressed Compressor
  • Cloudy Air Filter
  • Low or Dripping Refrigerant
  • Immoral Condenser
  • Electrical Structure problom
  • Stuck Blend Door 

Reason1. Run Depressed Compressor

Your car’s AC compressor is answerable for pressurizing the refrigerant unsolidified and circulating it through the system of hoses and conduits to cool your car’s curbside cabin. As a hardworking constituent, the compressor is very susceptible to failure due to attire and tear. In some car representations, it can also fail once you start it after a long historical of inactivity — such as when you try to change the air conditioning on for the principal time in summer. A failing compressor may source your 

Reason2. Cloudy Air Filter

Particular automobile makes, and models are prepared with a cabin air filter. Impartial as with your HVAC filter at home, your car’s air filter progressively gets clogged with dust and debris, so unvarying changing is essential. Moreover hot air blowing from your openings, other signs that your cabin air filter could be congested include musty smells or excessively loud noises when you’re consecutively the AC.

Refrigerant (also recognized as “coolant”) is a fluid that freshens your passenger cabin as it alternately increases and condenses, mingling throughout the air conditioning organization. Since the system is closed and airtight, your refrigerant source cannot evaporate or get used up. A low equal of refrigerant means you’ve got a leak anywhere, which should be mended before your coolant is outdid up.

Reason4. Immoral Condenser

The condenser is a energetic component of your automobile air habituation. Once the refrigerant has enthused through the compressor, the job of the condenser is to convey it depressed to ambient temperature.

The compressor’s location — at the front of your car amongst the radiator and the grille — allows air graceful through the grate to help with the cooling procedure. However, sometimes it also permits road grime and debris to get trapped confidential the condenser. The consequence will be a blockage or smooth breakage, such as the puncturing of unique of the condenser tubes.

Reason5. Electrical Structure problom

Your car’s AC is electrically powered, and the greatest common purpose for car air conditioning that blows hot air is an electrical classification malfunction. If any one of the mechanisms in its arrangement of fuses, relays, and adjustments stops working as it should, the complete electrical classification will shut down.

Reason6.Stuck Blend Door 

The mixture door prevents the warm air on the external from getting into your car. Uncertainty your blend door is trapped, the cool air generated will never get finished.

If your car air habituation isn’t feeling cold enough, feel permitted to bring your vehicle to the experts at STR Automotive. We’ll prudently inspect and diagnose your A/C problematic and have it fixed punctually.
