It appears that the Civic wasn't the only Honda with this "feature" engineered into it. The Honda Fit owners are complaining about the very same thing.

Another model has the same situation?? This really is changing my whole view of Honda automobiles as a top-knotch, high-quality product.
I had my first Honda in the early 90s and it treated me well. I've driven several different cars since then and at the suggestion of my SO - who's driven nothing but Hondas since the mid-80s - decided to go with the Honda EX w/ Nav because I liked it's sporty look and the fact that it really doesn't feel like a small car.
This AC problem is a Big Deal to me because my own internal temperature generally runs warmer than the average bear. I like and depend on a cold air conditioning system. Anything less is unacceptable!
Does anyone know what, if anything, would be accomplished by going to Honda corporate with this problem? Is there any recourse for those of us who are highly dissatisfied with this?

I have had three Accords, my last one being an 02, and I now have just over 2K on my 06 Civic EX 4 dr. I find the AC to be just fine. It does take longer to cool down than the Accord, but I would assume that would be due to the large windshield. Once cooled down, I have no complaints about the AC and it has been in the 90s, flirting with 100 degrees F today.
 
I have been getting just over 37 mpg on a regular basis, although I do drive mainly highway miles.
 
My only issue so far with the Civic is a plastic piece covering the seatbelt on the driver's side has either popped out, or has been that way since I took delivery and I never noticed. I called the dealership, and they will obviously fix this for free. Other than that I am (so far) very satisfied with the ride in general and very pleased with the mileage.

I am in the same (good) situation as melsinct. My AC works very well once get past the inital cooling down. Yesterday was 96 F on the drive home and no problems. I'm also averaging around 37+/- mpg (auto).
 
Just for information, I owned two 98' civics (1-ex, 1- hx), both black. The AC in both had a very hard time cooling the car, but I always attributed it to the cars being black which absorbs heat. My silver 2006 EX sedan AC has been very good. I also have not noticed the "blowing of hot air during acceleration" which I have been trying to pay attention too.

A/C by mcap56

I find the A/C to be better than the 04 Ex I had. That wasn't the strongest. The current A/C won't freeze you out but it does an adequate job.
 
Some general tips. I am sure you already know these but just in case......
 
1. Run your a/C on max/recirc to start and open the sunroof a little to get all of the hot air out.
 
2. Keep it on max/recirc.
 
3. Park in the shade.
 
4. Consider window tinting
 
5. Consider wearing sandals and going with bilevel cooling in hot weather. Your feel dissapate a lot of heat and the Civic vents direct air right at them.
 
   Had you decided not to get the civic because of the A/C, you might have ended up with a Mazda3 where by all accounts, the A/C is worse.

mcap56 - Good points of advice, with one exception. At first, it is best to use outside, or fresh air with the sunroof or windows open, as the outside air can be cooler making it easier than trying to cool the superheated inside air via the recirc function. Once the inside starts to cool down, it is then better to switch to recirc and close the window for better cooling.
 
You said " Had you decided not to get the civic because of the A/C, you might have ended up with a Mazda3 where by all accounts, the A/C is worse."
 
All accounts? I have to disagree here. There are many Mazda 3 owners who have no issues with their A/C. In fact, my son owns a Mazda3 in Tucson, where we have 4 or 5 months over 100 degrees, and he is very comfortable with his A/C.
 
I previously owned a 2001 Civic EX dark Blue, and I found the A/C to be weak, after the car sat in the sun all day. In city driving, it did take along time to cool the car. After me, my son then drove that Civic for 2 years before buying his 06 Mazda 3, and he states that the 3 cools better than the 2001 Civic.
 
I believe that in trying to squeeze every last mpg out of these small cars, they have downsized the compressors and other parts of the AC system, to where it may be just marginal in many cases...perhaps undersized in desert conditions.
 
Also, it has ben a design feature for MANY years to have a cutout function on the compressor for strong acceleration. I have had many cars over the years, even US made cars have had this...a throttle position switch that actually turns off the compressor under strong acceleration to aid the performance. It was able to be disconnected on many of my vehicles, but I don't know if this is possible today with the computers controlling so much in the cars, but it might be worth investigation for those of you who are bothered by this behaviour.

Good points. After reading all of these last night, I tried to monitor the A/C in my civic. Just so you know, we are in the middle of a monster heat wave and the NYC temp is over 100. Humidity is really high also.
 
I have to say that my car did a decent job of cooling. I put my hands to the vents during acceleration and I didn't really notice any major change. Perhaps it is an issue with your individual cars. Best bet is to act like you are interested in a purchase and take a test drive. Compare the two. Or, if someone you know has one, take it out and see what happens.
 
Oh...and just so you don't get jealous...I have the idle vibration and perhaps the suspension issue. So, I am not blind to the shortcomings of the car.

Well I have had my car since July 6th and have noticed this problem almost daily. i live in Southern California and drive about 20 miles from Orange County to Los Angeles County for work. I always notice this because the car seems to need to be driven at constant speeds to stay cool. If I hit traffic or a stop light, the A/C will blow out ambient temperature, which in traffic going 5 mph and its 100 degrees is pretty darn hot. I am glad to see other people with the same problem, I left VW for similar problems and high maintenance costs. I guess we will just have to wait for Honda to give us an answer to whether they intended this, or its a defect. Either way their should be a TSB on it soon. I have seen so many Civics around here I feel like a fish in a school of fish. BTW, I have an 06 Civic Sedan EX with Nav. Maybe is our below average Stereo thats causing it , I want the one in the coupe.

Dual mode compressor? by sotony
Aug 10, 2006 (10:44 am)

I have not had the discussed problem--I've been very satisfied with the performance of my AC even in the recent heat wave. One thing I have noticed is that when the AC is set on anything but the highest cooling setting (regardless of "max"--I'm talking about the blue to red temperature knob), the temperature of air blowing out of the vents does seem to go up and down, but it doesn't seem to be related to temperature. I've been renting for the past 3 years, though, and I've noticed this on a lot of other cars too.
 
I've always driven 4-cylinder cars and I've never noticed any problem with the engine not being able to supply enough power for the AC compressor. (including an '00 EX coupe)
 
I do seem to remember reading somewhere (it might have been in the manual or on one of the Honda info pages about the redesign) that the compressor has two modes of operation to save energy under light loads but provide adequate cooling when necessary. Sorry but that's all I remember. I'll try to do some digging. But might it be that the cars experiencing these problems have some type of programming bug that is preventing the higher-energy mode from kicking in? Does anybody remember reading anything about this?
 
Based on what I've said above, here's my two theories about what could be causing this problem:
 
1-A flaw in the temperature control knob or its supporting systems that keeps it from registering that you want the coldest setting.
 
2-A programming or electrical problem that stops the dual mode (?) compressor from getting out of its power-save mode.
 
3-referring to another thread somewhere on the internets, road debris has damaged your unshielded compressor.

Sorry--need to correct something in the first paragraph on my post. "...it doesn't seem to be related to temperature" should read "...it doesn't seem to be related to acceleration."
