Built in 1993. Not inefficient, but not overly efficient. Very typical of all houses built in this area (DFW) in the early to mid 1990s.
Two stories. 20', 15' and 10' ceilings. Over 3600 sq ft. That's a lot of volume to cool. What is your volume? The most I have ever used is 4529 kWh, the least is 849, with an average of 1863 kWh.
Three HVAC A/C central units - a 4-ton for downstairs, a 3-ton for upstairs, and a 1.8-ton for the master suite. (no window units, swamp coolers, etc.)
When it's this hot, we cool it to about 76° inside. Add in all the other stuff - washer/dryer, lights, security lighting, TVs, 7 stereo systems throughout the house, ceiling fans, her hair dryers, curling irons, stovetop, oven, etc etc.
We have had
eleven 100°F+ days just in August so far - and the other four days have been highs of 98°F+. We haven't seen a low temperature this month less than 83°F so far. The forecast for the next 14 days shows 100°F+ each day. It's been 30 days since we had any rain, so that ain't helping either.
Some years are hotter than others. Last year we had only seven 100°F days - all summer.
And no - you're not being anal. I have kept a spreadsheet since 2009 of monthly usage data. In addition, if you have a smart meter,
https://www.smartmetertexas.com/home is a useful tool. It currently shows I'm at an average of 129.6 kWh/day in August, so if I'm lucky, I'll only make it to 3888 kWh in August......
Saying that, I'm more than willing to use electricity - rates are lower here that most other places, and I didn't work for 40 years just to not spend money during retirement. I'm going to be comfortable. And since I haven't had any debt for 30+ years, I'm not too worried about the cost of this utility.
