Colder?

How can I make my AC blow out FASTER & Colder?

 

I've always been tempted to take the knob off and use pliers to keep spinning the shaft to the cold side to see if it works. Kind of like my dream of cutting a hole in the floor below the gas pedal so I can go beyond full throttle.

Friday's frame of mind aside, when you say colder and faster, is it not working well right now?

 

I notice mine gets better if I accelerate faster. Maybe you should just start accelerating and never stop.

 

Tint the windows darker or drive at night.

 

FYI slow and smooth blows are much more enjoyable.

 

If it's never been serviced it's possibly slightly low on freon.

Also put on re-circ for faster output.

 

Closing the passenger side vent will make the rest of the vents flow a little faster.
Pull down your blower motor to make sure it's not obstructed in any way.
Also check to make sure all the ducts are properly connected.

 

Good info, gonna add cleaning the AC condenser. And checking the refrigerant pressures. (Having the proper refrigerant at the proper pressures will have the best outcome, just adding a bunch more blindly from a can, can have negative effects on the rest of the system)

 

Lower the pressure until the a/c just about quits working.

 

This can also lead to mildew and musty, vinegary smells. Always important to turn off recirc for at least the last mile to allow fresh air through the system.

@OP you may also want to check for debris in the evap coil box.

 

You need to put a thermometer in the center vent to know whats going on. It should blow around 45 degrees give or take depending on the humidity and ambient temperature. That's what mine does, 2001, and never been serviced. It still freezes me out of the cab here in SoCal. The AC in the Tundra works the best of any of my vehicles I've ever owned. It does a lot of things really well, I guess that's why I still have it 20 years later.

 

Faster...divert all air ducts except the ones blowing on you. Also, turn the recirculate button on and select the ducts that blow directly at you.

Colder...replace all the O-rings in the AC system and recharge it.

 

I’m tempted to replace some parts in mine; ie the drier and the expansion valve, if they are easily accessible.
Me being the Reefer nerd I am, I dropped the entire charge, pressure tested with nitrogen and refilled per factory weight. But I kept going off on hi head pressure when I would drive it, hosed out the condenser and even that didn’t do anything, so I “recovered” a few oz back out and now it runs without tripping the limit, but I bet it could be colder!

 

The drier is the canister that sits right in front of your radiator. Expansion value, I'm not sure about that. It might reside in your dash.

I am curious how long what you did will last. I wish I had the equipment to evacuate the system and to recharge it.

Would a slow leak from an O-ring show up in a pressure test? I thought that occured over a time interval and might only show up if you tested how long the the pressure held over a few days.

 

So to add on this, awhile back I had the idea of sticking a microfiber cloth in the passenger's vent to increase flow to the driver's side. It works surprisingly well if you're driving without a passenger.

Of course this isn't a substitute for the other suggestions mentioned in this thread.

 

No real way to make it blow colder and faster. The system has limits. I’d have Freon levels checked and possibly replace blower motor and/or blower motor resistor. Blocking vents can help to divert to drivers side, and tint will help lower temps as well. It is a 20 year old truck…. If that doesn’t work, maybe this…lol

 

1.Replace a tired blower motor with a fresh new one
2. Have the AC system drawn down and refilled at the AC shop to ensure minimum moisture and maximum charge in the system
3. Ensure that no debris are blocking the intakes for the AC system
