A/C disappointment by stanaz

I've been driving my 2006 Civic for 6 mos. now (5100 miles) and I am pleased with the finish, exceptional handling, smoothness, and decent ride. I get about 39-40 on the road and about 33 in town so the mileage is very good as advertised. My only gripe is with the a/c. I live in Tucson and the a/c is barely adequate most of the time and poor at other times in the hot weather. All of my previous cars here (Subaru Legacies) and my present 2000 Toyota Avalon all cool really well under all conditions. I mentioned this to the dealer at the first oil change and they did test the a/c thoroughly. They said the performance test showed normal operation, no problems, and correct temperature output. The 2 mechanics who worked on the car both did say that Honda was never really known to have great a/c and that in hot climates it usually just barely did the job. There were no fixes and no specific tips they could offer since i was operating the a/c correctly. I had a 1988 Honda years ago which was fine. The very large glass area in the new Honda heats up the car quite a bit too so I guess this is something to live with in the hot weather. All of the cars good points help mitigate this problem.

I also live in Tucson, It does get hot (but not five months of 100+ temperatures as an earlier poster claimed), and Tucson WILL will reveal any shortcomings in an A/C system. We are talking about outside temperature here, but more relevant is solar radiation.
 
Most people out here in AZ use high quality window tints to deal with the solar gain. They work well. However, when you are headed toward the West or have an overhead sun, the 06 Civic's A/c will struggle as the front windshield makes for an excellent greenhouse.
 
I suppose that if Honda engineered their A/C for the most extreme conditions, it would be oversized and impractical the rest of the time. With the population growth in the Southwest, perhaps Honda should consider a Desert option that would consist of an Eglass windshield and ventilated seatbacks, which are terrific.
 
I think its interesting that Honda offers heated seats on many models, but not one Honda offers the ventilated seatbacks. I know roughly the size of desert communities such as Palm Springs, Las Vegas and Tucson/Phoenix. Is Fargo, ND really that big?

No real A/C problems here by psy

My EX Sedan has a good A/C in it. Even with recent 100f plus temps this summer it did good. I kinda wish my A/C compressor would cycle. It almost gets too cold at times.
 
The huge windsheild does lend its self as a good green house. Window tint helps alot in all cars. The better the tint the better it works.

Just to keep the record staright, in my post I said "in Tucson, where we have 4 or 5 months over 100 degrees" which is accurate. It gets over 100 in May, June, July, Aug, September, and sometimes even in October.
 
I have lived here since 1992.
 
I do agree with the rest of your comments, about tinting and solar heating being a big factor here. Tinting, and the use of a reflective sun shade for the windshield when unavoidably parking in the sun makes a big difference. Makes it easier for the A/C to cool the car faster.

heat problem by wsustudent

Hey guys I could really use your help on this one since its getting very cold up here in Michigan! The heat in my car is only working intermittently. It seems to cut out when I come to a stop (engine at idle speed) and starts blowing the outside ambient temperature. Then when i start accelerating the heat slowly comes back. The temperature gauge reads normal operating temperature, and the coolant is at the right level in the system. The blower speed seems to be the same as when it was functioning normally. I ran the self diagnostic that you can do from the service manual and no error codes come up. I don't know what else to look for. Any help would be greatly appreciated.

I have owned nothing but Honda Civics my entire life and they *ALL* have average AC, as described throughout this forum. Considered a problem by several auto owners, this trait (or fault) is by design and is only found on 4-cylinder engines, ESPECIALLY the engines that get 30+ MPG HWY.
 
This power-saving design accompanies another trait (fault) in Honda's electrical system: power to electrical systems (most noticeable in headlights and stereo dimmer) gradually increases over 20-30 seconds, then drops again. Just watch your headlights... they'll get brighter and brighter, and then BOOM- back to normal. Very strange.

Sounds like a coolant restriction...I'd check your thermostat and also the heater valve itself and whatever controls it (such as a vacuum servo).

Well I ended up solving the problem. Very simple...I was low on coolant! I thought I saw coolant in the overflow bottle when I checked but it must have just been a bad shadow or something that made it look like there was something in there. I figured out the problem when I was sitting in traffic and my temp gauge rose quite steadily to the H mark within 10 minutes in 30 degree weather with no accessories on. So yes there was a coolant restriction in the sense that there was barely any coolant flowing through the system at all! Now the next question...is there a leak somewhere that made me lose about 1/2 gallon of coolant within 4 years...I guess we'll find out. Thanks for the reply though!

You know that was my first thought but you did SAY you checked the coolant so I wasn't about to say "are you sure"? LOL!
 
You can buy a simple cooling system pressure tester that you put over the radiator as an air pump and this will find any leaks you might have that you won't see when the car is just cold and idling.
