The refrigerant in your system not only enables the air to be cooled, it also dries the air for comfort. Where we live, its not the heat so much as the humidity. Dryer air not only keeps the inside of your car from feeling sticky, that same dry air is what clears the inside of the windshield when you activate the defroster. Additionally, the refrigerant has lubricating properties that allow the compressor to operate efficiently for a long time, at the same time protecting the seals of the entire system.
Todays vehicles require an exact amount, measured in 10th of pounds, to operate at optimal effectiveness. Ass to that the strict requirements of EPA regarding the use of 134a refrigerant, this is not a do it yourself operation.
We recommend checking the A/C system every two years, or anytime the air doesnt quite feel right. Many systems will not operate without the proper level of refrigerant so as not to cause irreparable damage to the compressor. Our certified technicians are very capable to perform any maintenance or repair to todays systems.
