Model: Accord Coupe
Engine Size: 3.0
Refrigerant Type: R134a
Ambient Temp: 85-90
I have an odd problem here.
I don't know my pressures, yet, i loaned my gauges to a friend and am waiting to get them back.
Problem is when car is first started it takes literally 30 minutes before the car will blow cold air out of the vents, ( i call cold below 55 center vent temp)
it doesn't seem to matter if i am driving or idling. the car has two electric fans, and both are running on high speed. The condenser was replaced two years ago, (bumped into an expedition. lol)
The car has a expansion valve in it, instead of an OT. Could this be the problem, the valve sticking? Or did Honda just screw up the charge when they replaced that condenser? at last check when it was around 80 ambient outside temp i was getting about 35 on the low and 220 on the high if i remember correctly.
Once the car starts cooling it will go down to 48-50 out the vent weather idling or going down road. Thats when i had my gauges hooked up last..
what is causing it to take this long to cool down?

Your best bet is going to be to get the gauge's back on it. Sounds like a low refrigerant problem. Are you getting an excessive amount of compressor cycling or is it just running continuously? The pressure's are going to help out a lot though.
Thanks for the response I have been debating just evacuating the whole system and recharging to the proper specs. I think the compressor is cycling at higher rpms (2500 or so)
so it could very well be low on R134.
I have no clue how honda performed the service on it when they did it. figuring a whole evac would put my mind at ease, at the very least...
whats your opinions on the a/c booster stuff they sell in a can? I know its basically a special blend of oil you add during charging.. Is it worth the money? Or can it do more harm than good?
Most everyone around suggests not using any thing but pure 134a and the suggested lubrication.Leak sealers are band aids at best.Some dye can be used. finding and fixing the leak seems like the real money saving option!
Your on the right track though. The best thing you can do it evacuate out all of the R134a and charge with the correct amount of virgin R134a. Then check again. If it is short cycling at higher rpm it's most likely a low refrigerant problem.
Thanks for all the help! I am going to try and tackle it this weekend, i will post my results, after i evac and recharge
