I live near Phoenix Arizona (Mesa actually) and the A/C in my truck died this last winter but I just got around to replacing everything just a couple weeks ago. I've been told by several A/C guys that the A/C in these generations of Ford's just wasn't all that great. I've had several Ford trucks since I've lived here and all of them never could get very cold. They did the job but didn't have the capability to freeze you out on a blistering hot day. All the pressures and stuff was exactly where it should be so I just accepted the fact that the A/C's in these trucks just couldn't handle the excessive heat we have here in the desert.
OK, back to the present. I replaced everything with the A/C. Compressor, orifice tube, dryer, condenser, etc. I put in the appropriate amount of Freon and page oil, gave it a quick run and called it a day. A few days later it was forecast to be 104 degrees and I'm off to the lake. Great day jet skiing and I'm headed home in the heat of the day and I notice that I keep turning the A/C blower down. So I stick my A/C thermometer down the vent and I'm blown away by how well my A/C is working. It was down to 30.8 degrees at one point with an outside temp of 104. By the time I got my phone out it had risen a couple degrees but still........pretty impressive. I've never had any vehicle blow anywhere near this cold. I figure if it blows in the low to mid 40s, I'm doing pretty well.
for those of you that say "pic or it didn't happen," here ya go.
sorry for the rant but I'm just thrilled it worked out so well.

 

thats awesome, however at that low of a temp you have to keep in mind your evap core might freeze up

 

hmmmmmm, I didn't think of that. Something to ponder.

 

Actually it may mean theres a problem. It should not be that cold.

Your probably low on freon..or have moisture or debris in system. Moisture makes ice.....it plugs orifice...results in low pressure and temp in evap core. The air is colder on low fan settings, but overall heat removal ability is less. The evap core can also freeze up. Low pressure switch should cut it out before it gets to that point normally.

Properly operating it should run in the upper forties usually.

often being very cold and seeing fog coming out the vents in morning is the first sign that you're low on freon...it works great but then it doesn't work great in late in the afternoon when it's really hot.

 

Get another gauge, to verify! What year truck?

 

My truck has been pretty regular about being refilled on refrigerant. Last year was about a pound. This year I haven’t used my ac much so far so we will see how much it needs. My last refill was Mother’s Day last year.

 

Mines 17yrs old, no problems ever, still works great
I probably jinxed it just by saying that

Wife's Honda pilot is same way and it's 15 years old.
