and i've noticed that my car struggles when i accelerate while having my AC on..
is this normal?
Is there any code(s)? Any light lit up or flashing on the dash cluster? Sometimes there is no light indication nor the CEL (Check Engine Light) lit up but the code(s) is store in the car controller(s)/ computer. Most technicians will check for code(s) first before starting the diagnostic process. It helps to zone into the possible affected area(s) to get to the right path.
It does not matter if your Accord has an I4 or V6 engine, it should not be sluggish, lost of power or having up shifting problem. AC on or not. Period!
This link contains most available TSB (Technical Service bulletin) for the car. I've seen a few indicate the the PCM need to have an update for a newer software due to engine problems (ie: Fuel injectors, gears shifting, etc.):

This site will charge you to have the available into the details, just want you to look at the headline of the TSB to see the affect problem areas in relation to the car problems for both V6 and I4 engine.
Fuel, Ignition, transmission are the probable causes for the problem:
For V6 engine: 3.5L

For I4 engine: 2.4L (Is this what you have in the car?):

I would get professional help if I were in your shoe. It would be nice if you have the tools and mechanically inclined so I can guide you into the diagnostic procedures. If you prefer a much more privacy discussion about how to diagnose and repair the problem(s) E mail me and I'll reply. Check with your dealer about any TSB relate to the problems. Just call them. HTH
Edit: Get the code(s) read out at Auto Zone, Advance auto part stores (If you're living in the States) and update the information so other members can give you the proper advices. Stop by any trusty local repair shop (Check with BBB.com or friends, church members etc) for help. HTH
Dave and JJ are right, you can definitely feel a power loss with the A/C on.
The thing is, if you've had the car for a while, and the lack of power is something that has just started, then you do have an issue to address.
If it's always been like that since you've owned the car, then that's probably normal for this model car; the smaller the motor, the more you'll feel a loss of power feeling with the A/C on.
If it is a new problem, then look for things that can affect power, (dirty fuel filter or air filter, or a restricted exhaust/bad cat, etc.).
Feel free to ask me any more questions if you need to, I hope it helps.

Your A/C compressor may be dragging against the belt and requires more energy from the engine to keep the compressor turning, thus the power during acceleration is reduced. If your usual mechanic doesn't work on air conditioner equipment (some don't, it requires equipment that can capture refrigerant and such), ask him if he knows someone who does. Here's a website to know more about car repair: http://bit.ly/1vmd8MP
Any time I read a question like this I always think that the A/C system was worked on by someone that thinks more must be better and they put to much Freon in and that causes the compressor to go over pressure making it much harder to turn. It is that time of the year that all the A/C experts come out.
Most cars are,the a/c puts a big load on all vehicles.You have normal operation.
The aircon does sap some power from the engine when on but should not be that noticable
