Gave up gas furnaces after 20 years, now I eat my words
Back in 2003 I installed a high efficiency gas furnace in my place in Cleveland and swore nothing beat it. My buddy kept pushing ductless mini splits and I laughed at him, thought they were for fancy offices only. Last winter my compressor died and he loaned me one of his portable units for a week while I waited on parts. That thing ran quieter, used half the power, and kept my living room at 68 even when it hit 10 degrees outside. Anyone else switch over and find the old tech was actually the outdated one?
That week with the loaner probably saved you more than you realized, because once you see the numbers on your own meter it's hard to unsee them. The part people miss is that these units don't just sip power, they also skip all the duct losses that eat up a chunk of whatever your furnace makes. Your buddy was right early, but at least you found out before the next big repair bill.
