Although my apartment is equipped with a forced air oil furnace & complete duct system, I’ve never bothered with air conditioner. I live in the northeastern part of the country, where the Winter is the longest season of the year. The gas furnace is genuinely the priority, & I spend a fortune on energy costs. I look forward to shutting off the oil furnace, opening the windows, & minimizing my expenses. However, the summers tend to be excessively sizzling & humid. Leaving the windows open invites in pollen, dust, exhaust fumes, exterior noise pollution & bugs. There’s also a safety risk. When it rains, I’m forced to shut the windows & go separate from any influx of air. Running a bunch of electric fans is simply not enough to combat the heat & that clammy feeling. I’ve installed a portable cooling system into my bedroom window, but it’s loud, ugly & not energy efficient. I actually don’t want to buy a portable cooling system for every room in the house. I’ve decided I want a whole-lake apartment cooling system, & I’ve been researching the odd options. Modern cooling systems now achieve up to a 26 SEER, making them exceptionally energy efficient. Although the better models cost more, they spend my money for themselves in lower running costs. Since I already have the duct system in place, I’m hoping to afford a top-of-the-line model with a variable-speed compressor. Variable-speed technology allows the cooling unit to supply only the exact amount of cool air necessary. It can run at speeds between 40 & 100% capacity to optimize sound levels, comfort & energy efficiency.
