no you must run a dedicated line


Yes, with a caveat. The current ratings must be the same, the the 110V outlet must be a dedicated circuit, i.e. nothing else on that breaker. You can safely upgrade a dedicated 110V 15A circuit to a 220V 15A circuit by re-using the same wiring. You will have to just replace the breaker and the outlet. You cannot, however, increase the current load or have a 110/220V (4-prong) outlet. Note that if you move a non-dedicated circuit up to 220 you will start a fire.

You cannot use 2-120v outlets to power a 240v dryer. You can convert a 240v dryer outlet to power 2-120v outlets if they are supplied with a neutral. This requires a competent electrician. Do not do this yourself.

If your air conditioner is 120V but the outlet is 240V can you convert from 240V to 120V and how?

If the 220V circuit is dedicated, is to derate the circuit to a dedicated 110V outlet. Replace the 220V breaker with a 110V breaker and install a 110V outlet in place of the 220V outlet. If the original circuit was 20A or greater go with a 20A breaker and a 20A outlet as Airconditioners are fairly large loads. Do not exceed the current rating of the old circuit as that is all the current the existing wiring can handle.
