This indicates that the booster fan for AC has failed. If you look in back of the radiator, you will see 2 electric fans. One is for the engine cooling, and the other is a booster for when the AC is running to provide for extra air flow through radiator and AC condenser. (May also apply when engine overheats, but not sure of that) As car is moving along, then air is pushed through allowing AC to work. When standing still, and fan failed, then no air (or less air) passing over condenser grill. (Condenser is the one in front of the radiator) No cool.
While standing still with engine running, open the hood and look at fans. Watch your fingers. Fans can start at any time. One may be running or not. Now turn on AC and look at fans. Both should come on together. If not, then it may be either the fan, or the fan relay or fuse. Or even the wire.
Does the engine get extra hot while standing still running? Let it sit there for ten mins or so and see if main fan kicks on. Watch your temp gauge, you dont want it to boil over. When the temp reaches the level it is at normally, one fan should kick on. If temp keeps climbing and no fan, then that may be the same issue, likely the main relay.
If the fans ARE working correctly, and then you see them shut off when idling for a while, then I would take this to mean the Honda techs are right and not trying to rip you.
I think your honda vehicle is having a problem in idling tht is keeping the engine on in neutral gear that may be because if there is a vehicle standing in front of a vehicle in traffic at a signal light.

Ok you might have 2 problems. 1 overheating- do check and see if fans are working at normal operating temp. If you turn a/c on both fans should come on if they dont look for either the relay,fuse, thermostatic switch in the head under the distributor. K on a/c honda is talking about the a/c thermo-amp switch in the evaporator . The evaporator is behind glove box. Try those out.
