In this sentence "would" is used in English to express that the action was performed several times, or it was a habit (only in the past), it is not conditional. Pretty much the same as the imperfective in Russian. When I was a child, I would visit my aunt every weekend. When my father arrived from work, my sisters and I would come to say hi all at once. You can also do the same to express a habitual action in present, you have to use "will". No matter how much I try, the door will not open. (This sentence is not future, the "will" is just showing that I am trying to open it for a long time or by several means) I hope this helps.

they are both the same, just another way of saying it Would- is the conditional Used to- implies something that was habitually done in the past
