mappy Posted July 18, 2013 Share Posted July 18, 2013 On the topic of cooling the house, our kitchen gets hot as hades during the day and we couldn't figure out why... We realized when the previous owners redid the kitchen/dining floor they covered a vent. There is a cold spot on the floor itself. Doh Link to comment Share on other sites More sharing options...
Ian Posted July 18, 2013 Author Share Posted July 18, 2013 It does but my temperature is the same as Leesburg's so I'm not so sure that is correc...Plus my wind direction is southerly, I think it would have an easterly component if it were a true bay breeze convergence some.Yeah I checked the obs in the area plus wunder ground stations and whatever it was seemed quite diffuse. Only started to notice it around 5 so not sure on its origin. Link to comment Share on other sites More sharing options...

Mrs.J Posted July 18, 2013 Share Posted July 18, 2013 Good idea except I have tried closing the vents seasonally but there is a point where the system starts whistling which is very annoying. One thing that has helped is leaving the fan in the always on position so the air is constantly circulates even when the compressor is off. That works okay when it is in the 80's or cloudy weather or a thunderstorms to cool it down, house has a black south facing roof and zero trees so that really places a "hot top" on the upstairs. Electric bills are very good here, This June was just $ 97 last year had one in the low 200's, of course compared to the WV place with solar I sold in the spring these bills are high.. I averaged about $400 per year for the electric out there over the 7 years. I am in a 3 story home also. We put in ceiling fans on the 3rd and 2nd floor in every room. Fans on high we keep our air at 76 all day and the upstairs stayes cool. They help keep the electric bill down also. In the winter we just reverse them. We are installing solar panels this year. Someone told me that they help as an insulation layer over the roof, did you find that the case with yours? Link to comment Share on other sites More sharing options...
smokeybandit Posted July 18, 2013 Share Posted July 18, 2013 We got a new roof in spring of last year and it's amazing the difference in temperature upstairs. A day like today would be almost too hot to sleep in the bedroom. With the new roof, it's still warmer than downstairs obviously, but not that bad.

Ian Posted July 18, 2013 Author Share Posted July 18, 2013 Still haven't seen a 100 tossed out by MOS, tho maybe I missed it. NAM MOS has been doing pretty lousy this week as usual it seems when it's hot. GFS fairly spot on within d1-2 at least. Has dual 99s for our favorite hotspot JYO at 18z.

ravensrule Posted July 18, 2013 Share Posted July 18, 2013 Keep AC on 68 here... damn cookie cutter home with one system for three floors is the only way to keep the upstairs around 76! good news is the basement is probably 66 which is just right for chillin I love summer.. sweating my ass off on construction sites smelling like an unkempt locker room when I get home... only hit 95.6 here today which is so much more refreshing than than 98 or 100.. An attic fan would work wonders for you, it would probably take 2 or 3 degrees off the upstairs temperature. I have one and even when the temperature reaches 100 outside I can get my upstairs down to 70, although I do have 3 central systems. Link to comment Share on other sites More sharing options...

North Balti Zen Posted July 18, 2013 Share Posted July 18, 2013 Living in an old Balt City house. No central air, window units for the bedrooms. I can confirm that piling up the high minimums after awhile makes the living conditions pretty damn unpleasant in the main part of the house. When it never cools off at night, no way to get the built up heat out. Link to comment Share on other sites More sharing options...

Sparky Posted July 18, 2013 Share Posted July 18, 2013 I keep my thermostat between 77-78 on most summer days like today. Anything colder would make me freeze. I cannot fathom setting it below 70 like some on here do. Link to comment Share on other sites More sharing options...

Someone told me that they help as an insulation layer over the roof, did you find that the case with yours? The main solar panels for my WV place were on the barn roof and back fed the house electric. so in my case they had little effect. Seriously though it will vary depending on the install method, if they are rail mounted at least 6" above the roof surface. Tighter mounts trap more heat underneath (6" minimum I recommend since air flow and cooler panels perform better). There is know doubt the roof and attic area below the panels will be cooler. Send me a photo of your system when the installation is complete. And get a measurement or two of the attic temperatures now and then do that again on a comparable day after installation.

Thanks! 80/84 HI 85 currently. Heading up to the lake this morning. Thinking we will be spending our whole time in the water with plans to be leaving around 12:30 as I have to pick up a friend of one of my daughters. Should be a good time to bail.
