English - Writing A Common Thing As Something Unknown

Word: Heat pump

As I opened the door I felt a warm breeze flowing towards me, basking me in the warmth that was inside my apartment, I had never felt warmth inside my apartment before. I had always came home to antarctica almost inside my house. I could hear a noise in the living room telling me that something was on. I walk in to see what was causing the noise, a machine at the top of my ceiling whirring away and creating what was now the warm air inside the apartment. I didn't know how the machine got there, and how it was on but I was so relieved that I was finally able to sleep comfortably without having to wear a entire wardrobe. I walked to the kitchen and saw a note from the landlord telling me that she hired an electricity company to install what they call a heat pump into all the apartments without me paying anything for the rest of the month. I didn't like the noise the machine made, or how I would turn it off and on but I was still glad that I finally had heat inside my house. The note also said that the gadget could also turn cold, so if it got too hot in the summer I would have something to keep me cool if I couldn't survive the temperatures that summer brought when it arrived.
