I just replaced my central air (RIP mad money

). The quotes I got were CRAZY, as high as $2k in variation for the hardware & installation labor.
#firstworldproblem is that I replaced the A/C & had the guy peek into the furnace...turns out something had been leaking on the coils & was rotting it away, gotta replace that now too

Upshot is my unit is 50% efficient & the new ones come in 80 to 90% efficiency (gotta run a new tube out for the 90% unit tho). Oh, and the humidifier for the furnace was 110% shot. There's another five hundred bucks on top of the furnace. Ouch. And all of the installers I've talked to either want cash up front or half now, half after - no payment plans available. My buddy at work did their HVAC system in payments along with their gas bill, so it just added a hundred bucks or so every month for the next few years. Jealous!
