I have to throw in that SMO, I don't know about the other oil companies, is having major problems right now. I lost my heat, downstairs zone valve (I think) went wonky yesterday after the electricity kept going on and off (a result likely due to every heat pump getting turned on at once. Many of the new houses have three or four and even five of them and that surge blew the breakers on every transformer on the street out).
Anyway getting back to SMO, I'm now scheduled for a tech to come out Sunday. It was originally today, then tomorrow. There have also been reports of people running out of oil with no refill in sight. Apparently they're overwhelmed with "no heat" calls. Now, is that a staffing issue (rumors have been around that since they were taken over that tech slots have been cut to the bone) or just a perfect storm of one of the longest cold snaps in a number of years? I imagine it's a bit of both.
