Spped Sensitive Air Conditions?

[KillerPooh]

Hello all,

I have a 19 month old 2016 Genesis 3.8 RWD (Signature trim line). I have noticed that my air conditioning seems to be sensitive to the speed of the car.

1. It takes about 30 to 60 seconds for the system to start blowing cold air after startup and I often get warmer air until I speed up.
2. I have also observed warming of the air when I have to slow down (as in a traffic jam). When I say warming, I don't mean hot air .. I do mean "not so cold" air.

This behavior is repeatable. For instance, it normally takes me about 6 minutes to get from my house to the entrance to the freeway. During this period, the HVAC system is blowing air (typically about 2/3 max) until I get to the freeway. When I accelerate to freeway speeds, the air gets much colder.

Is this a bug in the system or is there some design flaw?

Normal operation for most vehicles especially if your car interior is already hot. It takes RPM to get the air conditioning compressor up to it's ability to work effectively.

Also keep in mind that we're no longer using the old R12 freon,AC temps aren't what they once were!😂
Now a days we all notice the warmer temps at idle.

You may want to have the booster fan on the condenser (in front of the radiator) checked.

Have the system checked, you may be low on refrigerant.

I notice mine is RPM sensitive. The fan boosts up once I start driving slowly, then ramps down at idle.
