Look at the name plate on the outdoor unit and post what type of freon is in the system. Should state a factory charge of r410 a or r 22?
What type of refrigerant? R22- 70psi is good/ r410- 70 psi not good. What is the head pressure, is the filter clean, is the coil frozen, is the fan operating properly, all the supply air grills open...lots of things cause funky pressures. Need more info

Refrigerant is R22 ,head pressure 225psi,filter clean,coil isn't frozen and air grills fully open
225/70 is perfect for r22. Yes, at 225 head pressure you would think that the liquid line would be a little warm but ambient temperature or if the line set is underground can both affect that. Check the temp split at the unit/ return air temp vs. Supply air temp. I say 17 to 20 degree difference is perfect, some guys say different. 14 to 22 degrees is the range. 75 degree return air should be below 60 degrees in supply. Good Luck.

If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.

Of your system is working correctly except for the switch, it should continue to do so without the switch. However, if something fails in the system you risk sustaining more damage...just as removing a fuse from an electrical system will. One thing you did not mention is the compressor relay...have you checked that? It feeds power to high and low switches, so likely you have.

I haven't found a really good wiring schematic of the A/C on these cars. But, I can tell you that I had an intermittant problem with my Civic air conditioner that sounds similar to yours.
Mine would work fine in cool and warm weather, but when the outside temperatures got hot, it would quit working. The fan would blow; the system had a good charge on it; and the green A/C indicator light on the A/C on/off switch showed the system as being "on". Despite all the indicators saying the A/C is "on", the compressor clutch wouldn't come on when the weather got hot.
In my case, the reason it stopped working when hot, was due to some poor solder connections at the A/C on/off switch, which is part of the Heater Control Assembly.
I removed my Heater Control Assembly (challenging job), and pulled apart the Heater Control Assembly (more challenging) to access the solder connections for the A/C on/off switch. I resoldered those connections (six solder points) and put everything back together and everything has worked perfectly ever since that time (two years).
I have never seen a wiring schematic that shows this switch with more than three connections, and that is why I haven't posted a schematic for you. If you want the usual schematic(s), you can find one on autozone.com for your Honda.
If you are not comfortable pulling apart the Heater Control Assembly, and soldering those connections, you can install a new assembly which is available on-line. I saw one listed through Majestic Honda for about $240.
I hope this helps.
Good Luck, Mark

you need to change drivers side temp door actuator then disconnect battery for 5 seconds and reconnect after changing the part, turn key on for 60 seconds with touching heater control to allow actuator to program and then it will work.
