    Of course, the farther away from the evaporation coils you get the higher the reading you can expect. I haven't taken a reading close to the evap coils, but I'd think it would be closer to the desired 45 degrees. I've been using a register about 25 feet away from the A-Coil.

    We've usually got to wear sweatshirts when watching TV.

    Weird timing, but they just sent me a PDF of their system checkup. 55 at the register 75 at the return, outdoor temp 92 at the time. I wasn't home so I don't know what register he was using. I'm willing to bet it wasn't upstairs though.

    Two zone was discussed and vetoed because the house is small and the vents aren't quite made for that. There would have been major work required.

    And no sight glass? That 55 degree reading is too high. Sounds like low refrigerant.

    I just went to a register much closer to my A-coil and the temp I got there was the proper 45 degrees. Did the guys who put in your AC unit put in a new blower motor? 55 degrees is a red flag that something is amiss.

    When I got my first central AC in this house I watched every stage of the installation and they apparently had no intention of changing out the furnace blower for one with variable speeds. That quickly changed.

    I just drove by a huge crew of Pepco (local electric utility) trucks, trimming limbs away from power lines near my home in College Park, Maryland, just outside of Washington, DC, and noticed a block or two away, in the direction they were working, that there were HUGE limbs leaning on the wires there, which will surely be gone tomorrow.

    Unfortunately, the trees these limbs are growing from are so close to the power lines that there will be new threats to those and other nearby lnes in another couple of years. By coincidence, my next door neighbor has a private, unrelated tree pruning crew working in yard as I type this, and I just noticed that the abandoned DirecTV dish on the side of my house, for which I had cleared a signal path three years ago, has that signal path now blocked by the interim tree growth.

    I predict that, within the next two years, I'll be updating this thread...

    We just had an inch of rain and wind gusts exceeding 30 MPH. Guess what happened next. :eek2:

    Yeah, had lights flickering, but didn't lose power here. There was a report of a Tornado in Herndon/Reston, but no injuries or damage from the tornado itself.

    Using known physical relationships, calculate for V(ac) for College Park, Maryland on September 18, 2012:

    Wind = 30 MPH
    RAIN = 1"
    V(ac) = 0. What else is new?

    This forum needs a timed, "sniper" function like I use for eBay. Tomorrow night, my power is going to go out. If I could just write the post now, and maybe connect it to an "app" that gets triggered by local rainfall or wind guts peak or something, then I'd be able to post it here before my power comes back on next week.

    I sneered when I saw a banner on the Weather Channel that "PEPCO warned its customers to be prepared." My one experience in DC has soured me as much as any resident.

    There's a point where even the best utility company in the world can't prevent outages. I think this is a storm like this. There is no way any utility in the path of this storm can figure there will only be minor outages.

    It becomes a balance between what they spend for tree trimming and sometimes what the customer allows to trim.

    We all want our trees but in a situation like this the trees win.

    Right. Plus when the storm passes, they have to do a lot of work before they can even start fixing lines in some areas. Debris needs cleared from roads, power restored in order of priority etc.

    My power went out an hour ago, even though the forecast rain had not even arrived. I don't know if my residential internet is actually out, but my personal internet service is out since it uses a powered router. I could snake an extension cord to my service truck and power the router off my inverter if I were so inclined, but the Verizon internet entrance electronics are, electronically, nearly 100 feet from there, so I'd be hard presses to scrounge up enough extension cords to power both.

    I am at a McDonald's and they have a 110 volt outlet, so I am "connected". And eating well.

    Still out, but I'm not holding my breath. Now, I'm in the conference center of Cherry Hill Park in nearby College Park, Maryland, a large RV/camper park with lots of amenities (shameless plug for a good customer). When I lost my electricity for a week about a decade ago, I practically lived here.

    By the way, one thing that rankles me about DC to AC inverters is that they shut themselves off even when a car battery has a lot of juice in it just because it has crept below their operational input threshold. Unfortunately for someone like me who would like to keep one connected to his spare vehicle for the duration of a storm, modern alternator/regulators do not overcharge a battery like the old electromechanical ones did, which is good for the life of the battery but bad for someone who wants to draw current to an inverter for a few hours. Does anyone know of any inverters that continue to operate at lower battery voltage charge levels?

    While you may want a couple more hours from the battery, that may be all you get. . . so inverters / chargers are designed to operate in the best range for the batteries.

    Drain a battery too much a couple of times and it's dead, Jim.

    I'd just get a small generator for a couple of hundred bucks.

    Or even a solar panel kit if you just want to run a laptop/tablet, etc.

    I gave up on all that stuff and put in a 14KV generator. Diana C was a huge help in this. We both used the same electrical contractor and if anyone living in Central/North NJ wants to contact them, send me a PM and I'll give you the details. I doubt that you'll get a better deal from anybody else. Most of the estimates I got were about a thousand dollars a KW. I paid nowhere near that price.

    Runs on natural gas, no gas cans to fill. No cords to hook up, everything is automatic. When the power comes back on, the gennie goes off immediately.
