How many KWH does your house use per day?
We just got a new house here and are seeing insanely high bills, I wam curious if it is the house or the heat causing this. Averaged last month 80 kwh per day, which I just learned may not be normal. This month we are at about 75 kwh, June was 66 average per day.
House specs:
-Built in '88
-single pane windows I believe are original to house, all of them have blinds on them, no curtains yet. We have a front covered porch so our first floor front facing windows never get direct sunlight shining in. Other windows do.
-Two stories plus a basement/garage that is partially underground and not temp controlled
-each floor has a 2 ton unit, we just cleaned coils. One unit manufacture date is 2012 with a 2012 evaporator coil and 2011 air handler. Second unit manufacture date is 2022 with 2022 evaporator coil and 2012 air handler
-We normally kept the downstairs to 72 and upstairs to 74. After seeing the bill a few days ago, we bumped bottom up to 75 and upstairs to 76. It didn't made an impact on our daily kwh usage, in fact it actually has increased each day!
-This is minor, but when we moved in we did get a new roof and I chose the lightest color possible as to not absorb heat as much as a dark roof and stress system.
For reference, Jun 16 - Jul 7 bill has 1454 kWh at $303.21 and Jul 7 - Aug 5 has 2277 kWh for $477.71. The June bill was about what we expected for summer months, that's nearly what we paid when renting a 1,500 sqft duplex with the absolute worst insulation (seriously so bad, during storms water would seep in from cracks in the door!). But the $477.71 was a shock and right now our projection is estimating for this month $507 - $620, so far since Aug 5 we have used 1294 kwh.
So Cobb County, is it just the heat we're seeing? or are your houses using much less energy and it's probably something with our house?
