Automotive Air Conditioning
Any automotive air conditioning system employs four basic parts-a mechanical compressor, driven by the vehicle's engine; an expansion valve, which is a restriction the compressor pumps against; and two heat exchangers, the evaporator and the condenser. In addition, there is the refrigerant that flows through this system.
Here is the deal, If you think buying one of those do it yourself Recharge Your Own Air Conditioning Kits that you by with the little cans of R134a Freon is the fix you may be in for a surprise.
The first thought in this situation is "why do I need more freon?" Well, more than likely you have a leak in the system and just shoving more freon in the system might make your Air Conditioning blow cold for a day or two but is not the Fix. Finding the leak , then fixing the leak before recharging the Air Conditioning System is the right way to fix the problem.
If you do not have the proper equipment to diagnose the problem, take it to a local repair shop in Springboro, Ohio where they can save you time and money!!
