I got by for quite a few years with several window air conditioners. They didn’t look all that nice or provide totally effective comfort. Certain rooms in the house were cool while others were hot and sticky. On especially humid days or nights, the window units struggled to achieve an ideal temperature. I didn’t like installing them in the spring and removing them in the fall. I finally decided to look into central air conditioning. Since my home is already outfitted with a furnace and ductwork, the project wasn’t overly disruptive or expensive. I found that there are modern cooling systems that achieve 26 SEER, making them surprisingly energy efficient. Today’s models also use an updated form of refrigerant that avoids ozone-depleting of Freon and is more environmentally friendly. Innovations in technology have significantly improved dehumidification and air filtration capabilities. Top-of-the line models automatically adjust output to maintain even indoor temperature. The system operates quietly and even allows for an upgrade to zone control. I am so happy with my central air conditioner. Now, the whole house is perfectly comfortable during the summer. I sleep better at night and am more productive during the day. I don’t need to clean as often because there is less dust, pollen and other contaminants floating around. Even when the weather isn’t overly hot, I still run the fan of the air conditioner. It works to circulate the air and keep it feeling and smelling fresh. I only wish that I’d have made the investment into air conditioning years sooner. I had no idea how much I would appreciate the amenities of it.
