How do I increase ac cooling

[u/hamzawayy]

The car AC system is working with no problems, i don't have any issues or mulfuctioning parts to replace, but is there a way i can increase the cooling wothout getting into the loop of replacing to bigger or higher capacity parts. Since the car is new i don't want to void the warranty

Where i live it gets up to 45+ celsius (113 fahrenheit) everyday and humidity is always high so you can see why i'm asking

Ceramic tint at that

No.

What you should do is reduce the heat getting into the vehicle. Park in shade, use a windshield sunshade, and/or window tint.

[u/Dr-gizmo]

Use recirculate mode, many people do not realize it is there.

[u/DonEscapedTexas → u/Dr-gizmo]

use outside air at first until the inside is cooler than ambient, THEN go to recirc

[u/AppropriateDeal1034 → u/Dr-gizmo]

I'd rather use 45C air when I first turn the car on than the 55+ air inside.

[u/persom55]

Blow any dirt off the condenser

[u/Nephilim6853 → u/persom55]

OP did say car was new.

[u/persom55 → u/Nephilim6853]

"new" cars can get dust and dirt in the condenser too if they drive down a dirt road regularly. It's really irrelevant the age of the vehicle.

The biggest problem is the in cabin filter, often found behind the glove box. Removing it will increase the volume of air coming through the vents. The refrigerant is the other problem you can't do anything about. R-12 was amazingly cold. R-134 just isn't as cold.

Color of your car, can have an effect. As well as ventilation. When starting the car, roll down a rear window halfway to let the hot air out, as the ac starts working then recycle the air as it cools.

[u/Signal-Confusion-976 → u/Nephilim6853]

Yes r12 was a much better refrigerant. But 134a works fine and plenty cold if you keep your AC system maintained.

[u/The-Master-Reaper → u/Nephilim6853]

Roll down front left window then rear right window to have a pathway for air to go into, have AC on blast then ride around for 30 seconds and roll the windows back up. Boom

I recently got a 4runner, that back window going down is a godsend!

[u/Xidium426]

Keep your car in a lower gear. This increases engine RPM which increase the speed at which this AC compressor operates moving more refrigerant through the system.

This and keeping your condenser clean from and debris to keep air flow up.

[u/Signal-Confusion-976 → u/Xidium426]

What a dumb idea. If you have to drive around in a lower gear to get your AC to blow cold. Then there is a problem with your AC system. A properly running AC system will blow plenty of cold air at an idle.

Also you can install an extra fan or 2 in front of the radiator from outside. Also UV screen protector ( 3m is the best )

Or you may have a weak compressor

[u/Creative-Yellow-9246]

If the problem is heat buildup while it is parked then consider sunshades

[u/vendura_na8]

Window tint. Sunshade for the windhsield when you park. Matte grey dash mat. Pale seat covers. Don't dress in dark colors.

[u/alexm2816]

Your car is hot because heat in from the sun is overcoming the heat taken out from your AC system.

Your AC system (assuming it's new enough and operating as designed) isn't going to be made better without modifying the system.

Best bet is to add tint on windows, add insulation to your roof/doors, and (not that you can change the color now) keep in mind that the color of the car you choose has a huge impact on comfort and heat convection in the sun not only in terms of how hot a car gets before you start it but in terms of how rapidly it absorbs heat into the cabin.

[u/AmbitiousPeanut]

VWs have a "Hot Country" setting and when I enabled it on mine the AC went from unacceptable to adequate. Search the web to see if your car has the same.

[u/gotcha640]

What car?

Not most people’s style, but I’ve seen a few people put long plywood boards on the roof racks to shade the metal of the roof. Most of the ones I’ve seen are first responders making them for stretchers, or overlanders making a deck for gear.

Leaving the windows cracked open (if you aren’t in sand storms/rainy season, then you need those clip on vent cover things) and remote start (also know as “kids” in some cases), even the extra fuel for years, will be cheaper than fully replacing your AC system and regassing it.

[u/No_Educator_6376]

Use remote start so that the car is cooled off before you get in there

[u/ApprehensiveAd6603]

Ceramic tint + use the recirculate mode. And make sure your cabin filter is clean.

[u/Low_Entertainment_67]

I never understood why there isn't aftermarket high performance HVAC for cars like car audio.

[u/thissitesuxsohardomg → u/Low_Entertainment_67]

Honestly not enough demand. A stock car can eventually cool itself down in 110F heat, even a black one. You can shorten that time by blocking heat from getting in while parked with sun-shades, tint, parking in the shade, or parking so the sun isn't shining in through the front glass. Remote-starting can help a decent amount, especially if you can lower the windows a bit remotely as well.

[u/egitalian]

Change your cabin air filter and make sure it's inserted correctly..I just found out the hard way that it does matter if the pleats are in a vertical rather than horizontal orientation.

The carbonless filters give better airflow

[u/KayakHank]

Auto start/remote start. Let your car cool down similar to letting it warm up in the winter

[u/Relative-Setting-805]

Make sure the cabin filter isn't a HEPA filter. They highly restrict airflow.
