Working wWithout AC

SinceFor four months ago We are, we've been working without AC.

You could also say, "starting four months ago," which would be a little closer to what you originally wrote, but I think the above sounds most natural.

It's a strange environment, because a lot of time We feels we get too hot.

We had talked with our autoritiesmanagement, but the response we got is not what was desired,e had hoped for; that is to say the hostile environment continues.

"Authorities" is technically correct, but it sounds weird because it typically means the police/government.

Despite this situation, my coworkers and I continue working every day without stopping or complainting about the situation.

I hope in the future to have AC again AC toso we can work in a refreshing environment.

SinceFor four months ago We are, we have been working without AC.

Putting "since" and "ago" in the same sentence sounds awkward because it may be redundant.

It's a strange environment because a lot of time Wewe often feel/it often feels too hot.

It sounds more natural when using "often" here because "a lot of time" refers to an extended period, like "we spend a lot of time studying," instead of something happening numerous times (in which case we use "often" or "frequently").

We had talked with ourthe authorities, but the response we got is not what wase desired, that is to say, the hostile environment continues.

I'm wondering if by "our authorities" you mean "our boss"? Like someone in charge of you at work would be your boss.

Be mindful of the verb tense. Since it seems you mean that the hostilities are still happening, the verb needs to be in present tense to reflect the ongoing situation.

Despite this situation, my coworkers and I continue working every day without stopping or complainting about the situation.

Using "situation" twice makes it feel repetitive.

I hope in the future to have AC again ACin the future to work in a freshcooler environment.

"Again" is usually placed after the thing you want to return to (in this case, having AC).

"Cooler" sounds better here because it relates to the temperature and compares to your current uncomfortably hot environment.
