My new roommate won't stop complaining about the temperature

My girlfriend and I broke up a few months ago and she moved out of the apartment.

We were splitting all of the bills and I could not afford to live in the apartment alone.

I decided to get a roommate to rent the other bedroom. I put an ad on Craigslist and I also placed an advertisement in the college directory. I received a lot of interest, so I decided to raise the price. That got rid of a lot of people, and I found a group of individuals that looked right for interviews. I finally found the perfect tenant and he moved in last weekend. We have a lot of things in common. We both like to go hiking in the woods and we both enjoy painting and sculpting. I thought we would have a lot of interesting things to talk about. Unfortunately, my new roommate spends most of his time in the bedroom. We rarely ever talk and I only see him for breakfast, lunch, and dinner. The worst part about my new roommate is all of the complaints. He has complained about everything in the apartment from the laundry room to the bedroom and bathroom. The latest complaint is about the indoor temperatures. He wants to adjust the thermostat so it is colder in the apartment. He doesn’t pay for any of the utility bill and that is part of our rental agreement. I don’t allow him to adjust the thermostat. It needs to stay on the same temperature at all times in order to save money. My new roommate is going to need to adjust to the indoor temperatures and stop complaining.
