Because of the weather in the part where I live, air conditioner is not a necessity. The summertime season constantly only lasts a couple of weeks. However, the people I was with and I do endure some very high uneven temperatures and humidity, however for quite a few years, I managed the warmer weather with a portable cooling system in the study room and fans throughout the rest of the house. I wasn’t ecstatic with how the cooling device looked in the window, and it jammed both the light and my view. Installing it every Springtime and removing it every fall was aggravating. The fans were noisy, ugly, and offered very little relief from the heat. Plus, they tended to stir up dust and aggravate my flu symptoms. I finally invested in a central cooling plan for my home 2 years ago. I only updated to whole-home air conditioner because of a manufacturer’s rebate. I was able to add air conditioner to my forced air oil furnace without much of an investment. The improvement has been amazing. My home is far more comfortable, stays cleaner and even smells better. Now that I’m able to keep all of the windows shut tight, I don’t deal with a whole bunch of dust, pollen, bugs, fumes or traffic noises. The central cooling plan actively filters the air, greatly enhancing indoor air quality. I’ve found that I start up the cooling system in the early Springtime, sometimes only using the fan to circulate the indoor air. I keep the cooling system running until late fall, and because of 26 SEER rating, it’s doesn’t cost all that much to operate.
