Repairing Your Car’s Air Conditioner: Is it Worth it?

When your air conditioner goes out right before the humid, sweltering weather sets in for about five months it seems like the best idea is to just buy a new car you are so desperate. You know that, logically, buying a new car is illogical but getting your A/C fixed could be just as impractical. 

Weak Airflow

If you notice reduced A/C airflow early rather than later and have it looked at before other fatal A/C system damage can happen. You might even be able to save it for a relatively decent cost.

Main causes of weak airflow:

  • Mold or mildew can accumulate in the evaporator core from residual moisture during the cooling process.
  • A loose hose, usually the blower hose that supplies air to the blower unit.
  • The ventilation fan is fried, and if the fan’s not blowing, air won’t flow well.
  • Core case seals, blower house seals, or evaporator core case seals can all open up and diminish airflow. A/C ventilation systems must remain sealed and once they’re opened, the whole system is done.


A/C Has Lost Its Cool

The lack of cold air could be caused by:

  • A clogged expansion tube or refrigerant charging hose.
  • Failed switch, fuse, relay, control module, blend door or solenoid.
  • Failed compressor or compressor clutch.
  • Failed blower motor or blower motor resistor.
  • Damaged or failed condenser or evaporator.
  • Vacuum leaks.
  • A Freon leak caused by a failed o-ring, seal, hose, or component.

When an A/C develops a leak, you have an “open system.” If it’s discovered early, your repair will be less expensive but, if a leak has been affecting your cold air for a while, moisture will most likely have entered the A/C system and may have damaged other more expensive parts.

  1. I have had issues with my A/C for a couple weeks now, and I think that having an auto repair company take a look would be smart after reading your article. I’m hoping that they can catch it early enough that it will be inexpensive like you talked about! I’ll have to call a few local auto repair shops to see what my best option is, but hopefully its the less expensive problem! Thanks for the information!

  2. Aeration and cooling system compressors in autos are belt driven off of your motor. All ventilation systems detract from the effectiveness of an inward ignition motor.

  3. The primary evaporator and blower framework took up half of the storage compartment space (however this turned out to be to a lesser extent an issue as trunks wound up plainly bigger in the post-war period). It was superseded by more effective frameworks in the post-war years. It had no temperature indoor regulator or stop component other than turning the blower off. Chilly air would at present infrequently enter the auto with any development as the drive belt was consistently associated with the compressor later frameworks would utilize electrically worked grips to cure this issue.

  4. For twenty dollars at any bait shop you could find an aerator machine that bubbles filtering the water for aquaculture.

  6. It’s a good site for me because i want to search this type of website and today i get success to find it.I appreciate to the author who share this information with me thanks.

  7. A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photovoltaic cell a device that converts visible light into electrical current.
