When I first graduated from college, I was really struggling for money. My job didn’t pay much, and I was responsible for huge student loans, a car payment, and insurance costs. Because of this, I kept myself to a very tight budget. I lived in a series of horrible little apartments, simply due to the inexpensive rent. These apartments were typically located in dangerous neighborhoods, but allowed me to ride my bicycle to work. The accommodations were often very old and outdated in every way. The floors were unlevel, the roofs leaked, the window never opened, and few of the appliances ran properly. I was always freezing cold in the winter, and terribly overheated in the summer. Every time, the furnace was positively ancient, and there rarely was an air conditioner. I spent the majority of my budget on outrageous energy bills, even though I was very careful with thermostat settings. Most often, the furnace would not provide a sufficient amount of heat, and I’d need to bundle up in sweaters and fuzzy slippers. Plus, it would spew a tremendous amount of dust and I was constantly getting sick. The heat usually smelled strange, and I always worried about fire, fumes, and combustion byproducts. If there was any type of cooling system, it most often leaked water, smelled musty, and ran continually without managing to effectively cool the apartment down. Looking back, I probably spent so much on energy bills, I could have afforded a better living arrangement. As soon as I got a promotion and a raise at work, I started shopping for a better apartment. One of the my priorities was a modern heating and cooling system.
