You're meant to. In fact, in older cars, it was automatic when redirecting air to the window defroster. On this GM control, the far right position would activate the A/C compressor. Almost always, it is a cold, wet day, and you have both sliders all the way to the right. The pass across the activated A/C coils dries out the air, because of the way ...

Yes, it is useful, okay and won't cause any damage. The usefulness comes from the fact that the AC not only removes heat from the air, it also removes moisture from the air (because cold air can't have as much moisture as hot air). The removed moisture clears your windows quickly. The only "damage" caused is the additional fuel consumption. On most new ...

R-1234yf is designed to be an environmentally-friendlier, near drop-in replacement for R-134a. Environmental legislations are pushing for refrigerants with lower global warming potential (GWP). R-1234yf is an attempt to address that, with a GWP that is over 300 times lower than R-134a: HFO-1234yf was developed to meet the European directive 2006/40/EC that ...

Yes , a leak is a leak . If the service information is correct. Efficiency falls as soon as you lose any refrigerant. And you certainly do not to need to lose all before the AC no longer works. My guess is a loss of half would shut it down; An AC tech could answer. My last several cars leaked none ; at least after 6 to 8 years the AC worked as well as when ...

HandyHowie is correct, kinda sorta. When you want to understand, really understand automotive mechanics you gotta start with a close look in your wallet. The #1 reason for the Air Conditioning (A/C) compressor to condenser hose discharge port is to save the automotive company money. Look at that port carefully. Notice it's a whole lot larger in internal ...

TL;DR: R-1234yf is expected to evaporate in the event of a spill According to the Honeywell material safety data sheet (MSDS), R-1234yf is fairly similar to R-134a, with a few key differences: Unlike R-134a it is extremely flammable, rated F+ In the event of an accidental spill, the MSDS states that the product is designed to "evaporate readily", unlike R-...
