how can I increase my AC

I was wanting to increase the amount of cold air coming into my pickup truck. I was wondering if you used a higher rpm blower motor to blow faster across the coil if it would increase the amount of cold air. If not could use a larger compressor, etc. to enlarge the system.........

are you certain the system is up to OEM specs now?? like charge level, clutch fan, pressures and temps may be nice- as well as type of vehicle...

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Just to add, remember that on lower fan speeds the air is always colder since it hangs out over the cold coils longer. I fan blowing faster will not be as cold, since it spends less time on the cold coils. As GM tech stated, a lot more information is needed, and we may be able to help you. Could be your evaporator isn't getting cold..Or a lot of other scenarios that we can only guess at now...
Hope this helps
