I'm on the plains in Boulder County. I have to replace my furnace (home built in 89; original furnace, Lennox G16 Conservator III), and have been scolding myself for pushing things.

I'm pretty busy through Monday, but this is a placeholder to remind me to talk with you. I'd like to increase energy efficiency (I believe I'm at 80% now with the current furnace) but can't spend a stupid amount of money chasing a couple percentage points in efficiency.
