I just got a Honda Accord and everything seems to be fine with the car.

However, the AC is giving me concern. I always need to switch it to the highest before I feel the coolness.

It's my first time using a car with AC so I'm wondering; am I expecting too much from the AC or is there really somethingg wrong with the AC?

Does your Honda EOD or DC Air conditioner need to be turned to the maximum before it chills?

In a sunny afternoon, does your Honda EOD or DC Air conditioner chill till the extent that you need to turn it off?

Is it normal for the AC to make loud noise?

All suggestions and contributions are appreciated.

Pls check your cabin filter.

Your car ac is low that is why you have to put it to the highest to feel the cold . Go and top up your ac gas and ask them clean the filter

I cleaned the filter yesterday. Still the same issue.

I just refilled the gas on Saturday still same issue.

Ask them to check the filter to see if it’s still good and not dirty . If the filter is okay then your car compressor is getting weak , manage it or buy another one ranging from 25-30k workmanship should be like 3k or 2k no let dem cheat . Tell them no need flushing na just to change the compressor and add gas won’t cost u more than 5k

Don't start throwing parts at your car. Take it to a competent AC technician to check what is wrong. A lot of things could cause your AC to be behaving the way it is. Expansion valve, Condenser, radiator fan can cause what you are experiencing. If you are in Lagos contact Mosbus, you will be glad you did.

Compressor does not make noise, manual compressor only vibrates the car engine. Noise only come from bad power steering pump. It’s common in honda

Story like say na u buy am. Compressor makes hell of noise. So u won't hear it abi. I replaced my factory ac to manual and since then na so so petrolni dey buy.i sold it off quickly. Once factory ac has been compromised. Just forget it. Or u buy same spec for 170k.

Take it to an AC specialist for a complete check...... I drive a Honda and the AC is much colder than mortuary standard...........

I have used few Honda’s. From bullet,baby,eod and evil spirit. Manual compressor vibrates the engine a lot and makes it consumes more fuel than variable compressor... what I meant by noise is constant noise. Not that little on and off noise which you don’t really notice on motion unless it’s stationary.

You no lie bro,well amazon is always there or aliexpress to do ac shopping. Enuf let's try this,oga it's the valve,I will top gas for you 5k,oga we go need loose radiator,do bypass . O bobs abeg make una no vex,I wan sell this car. Diff hands don open bonet,I don tire. My prayer is never to end up at mechanic workshop or rewire. I sell off quickly.

I use a 2007 Honda DC,I can only enjoy the AC during hot sunny afternoons because In the morning and evening I cannot use it pass no 2 fan setting even at that I have to turn it off after a few minutes due to the excess cold freezes my fingers and ice particles blocks the vent that no air will come out again,you will be seeing white ice flakes flying out of the vents like snow, incredible!,that ac is crazy,I sometimes use it to torture some passengers until they beg for mercy,I sometimes wonder if it is because the engine is a 3.0 v6 but the previous car I known was a 3.5 v6 Acura and the AC was not as potent as this Accord,

my brother I have used and owned 6 previous cars all with ac,including a Honda babyboy and a v8 Dodge ram pickup,but the AC in this 07 Honda is something else,now that it' is raining and the weather is always cool you simply cannot use the AC,the chill is torture and you cannot be comfortable without turning it off after 10-15 minutes,and if it is raining then it's double trouble ., sometimes I wonder if the AC in a 13 year old car is working like this only God knows how it will be when it's brand new.

Google mechanic ,I hail thee o ,how market bad,,evil and mature suggestion just flying around anyhow for issue wey una never see ,
Imagine someone even suggested that op should do outright change of compressor if filter is ok ,just like that And no need to flush the ac after u change compressor ,ok na , ignorance combine with poverty no go kill us .
My advice to the op is to find a recommended tech to check the ac for him and do away with all these change this ,change that suggestion for what they don't even know the root of issue.

Thank you everyone for your suggestions and contributions. I just found the solution today.

First observation
I put the car AC in auto mode today and discovered that it chilled well. The auto mode basically tells the car to choose the best settings for the AC based on the temperature in the car.

So I was wondering what I've been doing wrong. The auto mode is chilling but when I set it manually, it's not chilling. That's puzzle number one.

Second observation
Another thing I observed is when I turn on auto mode, the car also switches to the recirculation mode.

Recirculation mode basically means that the car only recycles the air that's already present within instead of taking fresh air from outside.

Now I have a second puzzle; why's the car switching to recirculation mode anytime I turn on auto mode.

Solution
As usual, I went to check the car's user manual but found no useful info. The user manual is a great resource but it didn't have an answer to this particular situation.
So, I decided to check Google and here's what I found.

Why the recirculation mode is cooler:

Using the Recirculation button helps get your car as cool as possible when it’s hot outside and you have the A/C on. It recirculates the kind-of-cool air that you get from the A/C when you first turn it on, and the longer it’s on, the cooler you car gets until it’s as cool as the system can possibly be. (If your A/C doesn’t get very cold even with the Recirculation button pressed, get your car to the shop right away, there’s likely a problem.)

If you use Fresh Air – the air from outside that’s much warmer in the summer, the air conditioning must work continuously to cool the hot air from the outside when pulling it into the vehicle, so it’s definitely not ideal. You are also putting undue wear-and-tear on your A/C compressor and getting less fuel economy as a result.

Why the auto mode switches on the recirculation mode
I found this on a Honda forum.

Our automatic climate control systems will select recirculated air when it's safe and efficient to do so based on outdoor temperature, cabin temperature, cabin humidity, and desired temperature (it's much easier to cool 75°F recirculated air than 100°F fresh air).

Not all brands and models of vehicles give you a visual indication of fresh or recirculated air when this selection is being made automatically. Most Hondas do, but my Regal didn't and my brother's Colorado doesn't.

It's still Summer. When temperatures start decreasing in the Fall, you'll notice that recirculated air will change to fresh air once the cabin cools down and the outdoor temperature is more than about 4°F below the set temperature.

So, auto mode is choosing recirculation mode because that's the best for the present weather. Most likely, it will not choose recirculation mode when the weather is cool like during harmattan morning.

Bonus
Another question came to my mind.

Now we know it's better to keep the car in recirculation mode on hot days becayit reduces workload on the compressor, saves fuel and gives cooler air.

But if the car stays in recirculation mode for long how will it regulate CO2 concentration especially if there are up to three people in the car?


Short answer:

Most cars are designed to avoid this. If the car is moving forward, while recirculating or even with fans off, a small amount of air is exchanged.

U no lie bro. DC a/c na something else.

I guess you don’t know much about ac when you were using dc. You can simply reduce the coldness to near warm

It is applicable to all cars and houses AC teacher

This is not about teaching or not . I have used Honda from bullet to evil spirit, I know how it cools. You can reduce the coldness, no be to Dey off ac every 15mins.

In other words, you didn't know how to turn on your car AC and you were almost going to start throwing parts at it.

That adjustment u are telling me is applicable to everything that uses cooling system. Call okoroemeka and lecture him on that. I am talking about his view on the cooling power of the car @ speed 1.

Everyone knows that

no be lie. even my own eod, if i set the fan speed to 2 within 30mins the driver side vent will freeze up and white icicles will be coming out. i would need to shut the ac off for a while to make the vent start dispersing cooling air again. i was suspecting the driver side air mix servo before. while this happens if i stop the car and open the bonnet to look at the compressor i will see solid ice block on the top of it even under hot sun.

i think it is a problem. normal working ac shouldn't freeze up vents at all.

The freezing will eventually damage your evaporator if you don't sort out the issue. It appears your compressor works in a continuous mode instead of cycling intermittently.

gbam! this must be the issue. please can you tell me what component of the ac system determines the cycling of the compressor? i always knew it was an issue that could lead to catastrophe someday. thanks
