I took it back to the dealer the 1st wk I bought it - NEW - back in 95 because I didn't think the AC was all that great. They said it was fine. I had it checked again in 2001 and they said it was fine. I checked the freon level last wk, it was spot on. So what exactly I'm I supposed to stop "messing with"? My 88 Supra is ice cold with 134 and ALL original eqt, my 99 Mazda is ice cold with 134, my 95 Honda with 134 isn't ice cold and never has been since I bought the car brand new. So you tell me what the problem is. BTW, It's a lot more humid in Florida than it is in Arizona and that also makes a difference. I bought a new Jeep Grand Cherokee in 1993. When I started having trouble with the A/C, I naturally returned it to the dealer. It went back several more times to the dealer. Then to a dealer in another city. In desperation, I finally took it to an A/C shop that does nothing but A/C. Not a sideline. They fixed it right away. That's why I don't think just taking it back to the dealer is going to fix the problem. Take it to someone who does nothing else for a living. Dick |
using 134 in 94 and it's obvious they were behind the curve and didn't
resolve the problem until the next generation of Accords. The added
glass area to the 94-97's didn't help the matter either.

I almost always run the AC even in cooler weather. So perhaps its ready for another refil. Perhaps it is, certainly. But not because you run it in cooler weather. Running it periodically even in cooler weather is good for it and keeps oil lubricated through the system discouraging corrosion and dried up "O' rings. I recently headed on a road trip through the Southwest. Its 110 degrees here in Las Vegas. The air coming out is only slightly cool and the interior temp is warm and and ranges from slightly uncomfortable to barely adequate. When the temp cools down to 95 degrees in the evening, the air from the AC gets quite a bit colder and the interior becomes pleasant. As a reference, my friend's 2003 Jetta blows cold even at 110. I am not sure if this problem is due to a fundamental weekness in the AC in Gen-4 accords, Not at all. There IS one fundamental weakness you should check yourself. Frequently the female projecton of the temperature control knob splits and fails to turn the control all the way to cold. A new $3 know will make a huge difference. or if I need a refrigerant refil. I honestly don't remember how my AC performed in these temperatures in years past. Places around here in vegas want $130 just to even look at it (although it includes the refil). That's fair if professionaly done. So I am looking for hear from Gen-4 accord owners who can verify the performance of the AC, before I go spend any money on this. I'm not an owner but we work on these all the time at my shop in central Texas where it might not reach 110* but it does reach 110+ frequently with lots of humidity. These AC systems work quite well, typically blowing 43* out the vents at maximum fan speed minutes after car starting up the car which has been parked for in direct sunlight for a few hours.

Don, I brought it in to a trusted mechanic and he actually found that at high temperatures, the AC fan didn't spin which was causing my engine coolant temp to rise in heavy traffic and to inhibit the cooling capacity of the AC. I had the fan replaced and things seem much better. Although, I am still not sure if it also needs a refrigerant refil. At high oudoor temperatures, the AC still seems to strain to keep the car cool enough. So I bought a small thermometer to attach to the AC vents. At 104 degrees outside, and with maximum blowing speed, I get only about 50 degrees sitting at idle or driving slowly in traffic. It does indeed cool down to 43 degrees when I am driving on the freeway (which makes the interior nice and comfortable). It goes back up to 50 degrees when again at idle. Would a refrigerant refil help keep the AC cooler at idle? Thanks again for your help. |
When it's 104 outside . . . Take a siesta.
Keep in mind that if your refrigerant was too low (or too high) the
compressor wouldn't cut in at all, due to the limit switch. If you could
actually clean ALL the dirt and leaves and debris out of your AC system
(on an older Honda) you could probably get better efficiency from it.
That's part of the reason for the introduction of the 'cabin filter'
which keeps those cooling fins cleaner longer.

increase it since it keeps the rubber seals lubricated. It's people
who don't touch the A/C for 6 months in a row who are more likely to
need their systems recharged.
Try feeling the evaporator's inlet and outlet pipes, which pass through
the firewall. After the A/C has run for at least 5-10 minutes in
recirculation mode with all the doors and windows closed, both pipes
should feel equally cold, about 32F, when the engine is run at about
2500 RPM.
