Yea, we started at -12°. Yesterday was -6° and hardly had any no heats. Today the bottom dropped out. Calls out the wazoo. I even had to work. Started off slow, took 2 hours to figure out there was a sag in the PVC flue in the attic. Doh! Had an installer running service. After 3 hours couldn't figure out what was going on. I came by, tried a new gas valve. Same thing. Called our best tech. Ya got gas he asks? Gee, why no!
Shot below is the new downtown cooling plant. 1 if 3. Really belching out the steam, those towers were going full blast!
