u could be right, this is my first summer in TX. i came from NJ, where the highs were 85 lol.
im going to check some things out this weekend, let u guys know...

It blows 'cold' for me but had trouble getting the cabin cool.
This all said, I have found honda's not to have frigid AC units. Our TL had the same problem which was only partially improved with a charge. Unit had lost a few PSI over 10 years.

I dont know much about this or if our system can be converted but..... a few days ago I heard a guy talking about a new r-12 refrigerant that does not have the bad impacts on the environment like the original r-12... so maybe look into that

Older cars use R-12. (My old 1990 300zx had it.) They stopped putting R-12 in cars because it kills the ozone layer.
Now days, (like our s2000's) use R-134a. This is the stuff everyone uses now, its less harmful. In fact, you cant even get R-12 unless you have a certified licence to buy it, and most shops wont touch R-12 anymore. There are conversion kits to go from R-12 to 134a.

Did u not understand what I said? I think u need to do a little more research before u go bashing on me.... I realize r-12 was used a while ago and is bad for the environment hence y I said there is a new r-12 that does not have the bad effects on the environment.... r-12 is much more efficient at cooling than r-134. So I don't know much about the new r-12 as I just heard someone talking about it when I was at work I also don't know if it as good as they were saying it was... all I'm saying is r-12 would def solve his cooling problem but he needs to do the research about this new r-12 to see if it would work out for him.

Plus R-12 has different ports on the A/C lines. Thats why you have to have different gauges for R-12 and 134a. I highly doubt they even make 134a to R-12 conversion valves. That would be dumb.
P.S. I worked at a technical school at the Automotive program, and worked on tons of A/C systems, so its not new to me.

Lots of service shops can recharge AC and will also tell you if you're running low on refrigerant. If you feel adventurous, go to AutoZone and buy a refill kit with the hose you need and a can of 134a I think they run around 30-40 bucks. Attach the hose and keep an eye on the gauge, I've done this before on other cars, the AC in my S has been keeping up decently with the recent heat here 90 degrees + in Houston.

Be VERY careful - almost all substitute R-12 replacement Freon is nothing more than a mixture of propane and butane. (Can you say "BOOM")
It's better to stay with the factory system. You might also buy on of the headliner inserts I've seen for sale. That will give you some insulation where non is now.

Lol, you might want to do a little more research of refrigerants man.

Also it's a common misconception that "low" on freon means your A/C isn't as cold as it should be. In fact the opposite is true, the lower on freon you are the lower the temp will be, however at a certain point the Evaporator will start to freeze up and then no air can get through. If you have to much freon the compressor won't work correctly and it'll be hotter. You want just the correct amount. It's always best to have a professional do A/C work, never buy those DIY kits from Auto Zone, they won't put the right amount of freon in ever.
I believe Cold side of the A/C service port should be around 35PSI, if you happen to have the correct A/C gauges to hook up to your car.
When we serviced A/Cs at the shop we aimed for about 38-42 degree air coming out of the Vents with an Ambient temp outside of 95 degrees.
