Max Air

AC Service   It’s 98 degrees outside and your car has been in the middle of a parking lot for the last 3 hours. Temperatures inside it can be upwards of 150 degrees or more. This is not the time to be without AC. The AC system on a modern car is a sealed system utilizing a small amount of pressurized gas (usually less than 32oz.). Unlike various fluids in your car; the engine oil, transmission fluid, antifreeze, etc., the refrigerant in your AC system does not wear out, nor does it need to be changed as routine maintenance. It does however, leak out.             Max On! Max Off! The AC system parts are subject to wear and failure. A simple O-ring can break-down over time and cause a small leak, or the flexible hoses - which carry refrigerant to the various other parts of the AC system - can rub against something and create a passage for the refrigerant to leak out.   The refrigerant used boils at (negative) 15 de ... read more

It’s a simple question, but requires a complex and lengthy answer however, we don't have time for that, so I'm going to try and make it a little easier to understand. I could write paragraphs of technical jargon, but in the simplest terms; Your car has a computer – actually, it has many…upwards of 20 or more. Your computer has one single way of letting you know how it’s feeling. We call it; the “Check Engine” (CE) light. If the light is off – the computer is happy (for the moment). If the light is on – the computer is unhappy (for the moment).   Not all CE light look exactly like this one, but this is the most common design.   ... read more
