I went without central air conditioning for a actually long time. I live in an section with actually long & drastic Wintertime weather, & the furnace is a priority. Because of the short summer season season, air conditioning isn’t necessary. Most people get by with portable cooling units, open windows & box fans… However, the outside temperature often climbs into the high nineties, & the humidity is ungodly. My house was overheated, sticky & horribly uncomfortable. I hated leaving the windows open because of the security risk. Plus, I didn’t appreciate providing access to bugs, pollen, dust, exhaust fumes & noise. I’d often wake up in the middle of the night because of a barking pet or traffic sounds. I was continuously vacuuming, dusting & battling mold & mildew. When my daughter started having troubles with pollen irritations, I used this as my excuse to invest in central cooling. Because I already have a forced air oil furnace in arena, I was able to use the existing ductwork & air handler. I also took advantage of a manufacturer’s rebate to further trim down the replacement cost. I unquestionably didn’t care how much it cost because I so badly wanted a whole-house cooling system. I now keep the windows closed, adjust the thermostat & prefer the perfect temperature. The outside heat & humidity make no difference to indoor comfort. The system is quite energy efficient, runs quietly & provides exceptional air filtration. I keep the windows shut & securely locked, & my house remains much cleaner. I start up the central air conditioning at the first sign of Springtime & keep it running until the actually end of fall.
