how can i mae my air con blow even cooler air, it works but is no where near as good as my girlfriends?

Question

or my dads the fan can blow really hot air but with summer coming i'd rather be able to get it better than juct cool, will changing my engine coolant affect anything?

Answer 1

No your engine coolant has nothing to do with it. Sounds like your air conditioning unit needs to be recharged and serviced.

Answer 2

Hi

Changing your coolant won't make any difference because the aircon actually cools the heat from the coolant to the desired temperature using a refridgerant as it passes into the vehicle.

Whilst you're using your aircon, set the blower to RECIRC so that no air comes in from outside. Then this way, the air will cool quicker and the aircon won't have work anywhere near as hard because it is using the air that it has already cooled.

I will add that it does sound as though you need to have your aircon recharged. The refridgerant is probably running low.

Our local branch of Halfords does it for a tenner plus the cost of the Freon.

Its a good idea during the months when you're not using your air con to run it once a month to keep it in good working order or things can sieze up.

Have it recharged and see wht happens.

Best of luck

Hi Evander -
It has nothing to do with your engine coolant.
Your A/C system has a maybe prob.
First thing is to get the system charged up with stuff called freon gas, from a 9 series bottle. Should be green.
Then they should check for any leaks.
Often a small pipe or joint leak can "knacker" the system

I am used to big air-con units, so it seems that the system is not getting enough flow of the needful.

Assuming that the fan unit is blowing across the evaporator, and the compressor, driven by a belt is not squeaking & misbehaving, all should be well.

Dear me - I thought that I had dissapeared from all these air-con things !
But there we go.

All the best,
Bob.

If you do have air conditioning in your car have you actually turned it on. There will be a separate switch or knob to do this. I had the same problem because I saw lights showing on the heater/cooler unit I assumed that it meant that the A/C was on. In fact there was an additional push button to bring on the A/C and all worked well. The engine cooling is nothing to do with the A/C.
Hope this works as it will be cheaper than paying for a repair. Check the handbook.

Answer 5

It's most likely that the refrigerant system is low on gas. Regular servicing of aircon is important for health and to maintain the system working effectively, as up to 15% of the refrigerant gas will be lost annually from a nominally gas-tight system.

Run your air conditioning at least once a week throughout the year.
Have the refrigerant gas checked regularly and topped up to manufacturers' recommended levels.
Help improve hygiene and air quality with a regular cabin filter change, as it can become blocked with pollen.
A regular air duct clean helps remove the bacteria and fungi that can cause unpleasant odours.
Service air-conditioning units every 30,000 miles or two years to avoid costly repairs.

Answer 6

If your girlfriend's car is older than 1994, and yours - yonger, the first one has R12 refrigerant, and the second - 134. The first one is harmful for environment but provides better cooling. If your car is small it may not have the same ac performance as a big rig due to limited engine power available. And, of course, there is a possibility of numerous malfunctions. Is your AC getting worse over time? Then it's leaking. Has it been same for years since you bought it new? Then it's normal. I can go on indefinitely but a specific answer can only follow a specific question. Sorry...

Answer 7

Your coolant will not alter the air con , it is the unit what needs charging .

Answer 8

there can be only one problem , gas. if there is no gas in it , it will blow hot air. i advice you call the technician to put in more gas

Answer 9

Get it recharged
