Most St. Louis drivers don’t even think about their car air conditioning system unless it fails. That’s because many Barnhart and Arnold motorists don’t really understand that automotive air conditioners need periodic service. Let me share some of the reasons why they fail.
First, like every machine, the sedan air conditioner parts need – you guessed it – lubrication. The lubricant is actually mixed in with the refrigerant (that’s the stuff that makes the air cool). Remember that even if the air conditioner is still blowing out cool air, the oil that lubricates the parts may be used up: and unlubricated parts can fail in all Missouri cars.
Now here’s a tip for St. Louis drivers: Run your air conditioner every so often during Missouri winters. This circulates the lubricant to help keep the seals from drying out.
The air conditioner actually removes some of the moisture in the air. So if you have trouble with fogging on your windshield during Missouri winters or during a rain storm, running the A/C on the defrost setting should help. Now on some St. Louis cars you can’t run the A/C at the same time as the defroster. Don’t ask me why, but I suspect lawyers were involved.
Also, air and water can get into the A/C system. That can reduce the efficiency of the system and also lead to corrosion that causes damage. St. Louis drivers should periodically purge the system and replace the refrigerant to remove the air and water.
Barnhart drivers would be wise to learn the early warning signs of A/C trouble: 1) The air’s not as cold as it used to be. 2) Unusual noises when the A/C cycles on. Those are signs to get your vehicle into Kevin’s Car Care in Barnhart before the damage gets worse.
By following the recommended service intervals in your sedan owner’s manual, you can help prevent mechanical failure of your air conditioning system. Your A/C system contains some expensive components like the compressor, condenser, dryer, etc. Anything Imperial and Arnold car owners can do to lengthen the life of their A/C is well worth it.
