If there is a 240V outlet but the air conditioner is only 120V can the outlet be converted?

Consider if it would be a good idea to leave the existing 240 volt circuit and outlet alone. It would then be available for use for some other appliance in the future. Instead of converting that 240 volt outlet, put in a new 120 volt branch circuit fo the air conditioner unit.
A new 120 volt receptacle of the right type and size for your air conditioner and a new 120 volt circuit breaker can be installed in your home's main breaker panel, along with a new cable of the right size to carry the current drawn by your air conditioner unit.
If you do decide that you want to convert the existing 240 volt outlet, you must keep in mind that the amperage drawn by the 120 volt appliance must not be more that the current-carrying capacity of the existing wires which were once installed for a 240 volt appliance.
For example, if the existing 240 volt circuit is only for 15 amps and the new 120 volt air conditioner needs 20 amps, it will not be safe to convert the existing wiring. New wiring of the correct size must be installed.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can 240V washer run on 120V outlet?
No.
What happens if you plug a 120V appliance into a 240V outlet?
You will burn up your appliance!!!!!
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
Can you plug a 120v 20 amp wielder into a 240v 40 amp outlet?
Absoluteyl not.
I have 240V 3 wire twistlock plug and want to wire it so I have 120V outlet?
Don't!
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
Can you take a 120V winecooler to Europe and use it with an 240V outlet and an adapter?
NO, unless you get a converter that converts 220 to 110.
How do you hook the 4 wires which are 2 whites 1 red and 1 black coming from the back of a generator to an outlet for 120v and 240v?
The whites are Neutrals or Grounds and the Red and Black are each 120v. One white and either the black or red for 120v and one white, both the red and black for 240v.
If you have a 240V 22A welder which has a plug similar but smaller than a dryer plug can you use this in a 120V outlet?
yes ofcourse they both are the same
How do you upgrade from 120V 15A to 120V 20A or from 240V 20A to 240V 30A?
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.
Can you convert an existing 120V plug on an appliance to a 240V plug not speaking of a converter but actually changing the plug so there are no long term effects on the appliance?
If I understand your question, Can you run a 110 appliance off of a 220 volt outlet? You could by only using one leg of the 220. You may also consider changing the outlet. Put in a regular 110 outlet and capping off one leg of the 220 in the wall box. You still have a neutral and a ground to work with. I read this as the questioner doesn't want to modify the outlet. Check the voltage ratings on the device. Many electronic devices nowadays can havdle 120V or 240V as it is cheaper to manufacture one powersupply and sell it everywhere. If your device is rated for 240V, you can put a 240V plug on it. If it only says 120V, no dice. 240V will burn it up.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
