While 220/240 Volt electrical lines can always be installed this can add to the cost of installing a heat pump unit.
With most outlets wired for 110/115v a unit that matches this voltage is often the only choice.
With this in mind there are some 110/115 Volt heat pump window units available.
As always be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.

Keep in mind other electronics that may be on the same circuit as the outlet you plan to use.
Units like that above are likely to draw 10-20 amps. If there is other electronics on the same circuit breaker it will flip off if the amps are exceeded.
One way to tell what outlets are on the same breaker is to plug into the outlet with a electronic device such as a radio and turn the breaker off. Other electronics on the breaker will also go off giving you an idea what is being used.
Also heat pumps have a low temperature rating which they can work and pump out heat at. This can vary from unit to unit.
Most heat pumps can work down to 20 degrees Fahrenheit without much problems. Below this and the outside condenser can begin to ice up. When this happens most will use heat strips which work like big space heater to send out heat.
If the temperature does drop low enough for the heat strips to come on it should only be temporary while the condenser become unfrozen.
