Questions & Answers about La climatisation qu'il a testée ne fonctionne pas.

Why does testée have an extra -e at the end if it uses the auxiliary verb avoir?

In the passé composé, when the direct object comes before the verb, the past participle has to agree with its gender and number. Here, the direct object is qu' (referring to the feminine noun la climatisation), so we must add an -e to make it testée.

Why is it qu'il instead of qui il?

The word for "that" here is the relative pronoun que, which acts as the object of the verb (he tested what? The air conditioning). Because il starts with a vowel, que drops its -e to become qu'. If it were the subject instead of the object, you would use qui, which never drops its -i.

The current lesson is about ne... pas encore. How would using that change this sentence?

Adding encore would make the end of the sentence ne fonctionne pas encore, which translates to "does not work yet". Notice how both ne... pas and ne... pas encore follow the exact same structural rule: they wrap directly around the conjugated verb (fonctionne).

Do French speakers actually say the full word climatisation in everyday life?

They do, but it is extremely common to shorten it to la clim in casual conversation, similar to how English speakers just say "the AC" instead of "the air conditioning".
