Narrative:

We departed and upon rotation we heard a blowing sound similar to the cabin blowers except significantly louder. We had also noticed that extremely hot air was getting into the cabin. I glanced down at all the environmental controls and noticed that they were in their appropriate position. We advised ATC of our situation and leveled off around 5;000 feet momentarily to troubleshoot. At that point; we noticed what seemed like smoke in the cabin and cockpit. We [advised ATC of the situation] and decided it would be best to land back at [our departure airport]. I started to run through the associated checklist for smoke in the cockpit; but never got a chance to finish the checklist due to other cockpit activities that took priority and the flight itself was less than 10 minutes. We landed safely; and the crew and passengers exited the aircraft.
