5500 sqft. Built in 2011. Day time set back to 75F. Or else it's at 70. 69 during sleep hrs.

70!!?!? I would need to wear pants and a sweater with the AC at 70. Wow.

Ours is about $14 but we have solar. Before solar it was about $200 a month, sometimes more.

1900 sq foot rowhouse in DC, 85+ years old. Our A/C unit is also about 15 years old and will likely need to be replaced in the next few years. Not looking forward to that bill but I am looking forward to getting a more efficient machine.

This for a very small 900 foot house and basement (which has heat/AC). Used to be $400 before we got insulation in the basement, new siding, windows, roof and HVAC.

Curious what type of siding you got and if it was insulated?

Hardi and only got thin foam board under it. Attic is not well insulated (future project). We just insulated basement with foam board and roxul (and drywall) including ceiling and that helped a lot. Main walls are not insulated (were when house was made but not much left now when we've opened walls).

PP here. Forgot to add, its about half that during the cooler months.

DC w/ PEPCO - 40-50/month

We have solar panels on our building (condo). Thermostat is at 76 when home. I turn it off during the day since its easy to heat and cool. It was 86 when I got in a few hours ago but I've been out of town for a few days.

Last month was $140, this month will be about $150.
1800 sq ft, Pepco in MD, and a NEST thermostat.

Just under 200 last minth. 3500sq feet, set at 68. Lots of people home all day...auPair, DH and I who WFH, kids, their friends.

Have you tried getting a "smart" thermostat like nest? It manages the temps in your house all day, notices when the house is empty, etc.

I don't know how much we saved on which changes, but I live in a 1200 square foot rowhouse (100+ years old). We were paying around 250-260 for heat and electric (averaged out over the year). As part of a kitchen renovation, we replaced some insulation and a couple of windows. We also installed a nest thermastat. Our bills dropped to $170 per month over the year.

$150-$250. Usually $200. This past cycle was $220, but I worked from home for 2 weeks and we had guests the other two, so lots of AC all day and in and out of the house and such.

Usually we set it to 75 during the day while not home/72 while home/70 at night. Dual zone, 3600 square feet over 3 floors.

energy efficient home here under 10 years old

$200 average in the summer

74 - 73 during the day

72 at night

home all day so I refuse to be hot

We've got solar (a fully prepaid 20-year lease, which we're five years into -- it cost us only $1,800 because the District paid the company the REIP incentive, which reduced our price, and then we also got another $400 for referring someone to the company, so it was $1,400 net).

Our electric bills this summer:
May $29
June $36
July $85

House is about 1,600 square feet with central air that runs quite often during the day because one parent is home with kids.

This thread makes me feel slightly better - ours was $200 this month, and I just about died. We do have a nearly 20-year-old HVAC system, though. If we got a more efficient one, it'd probably be less.

That's awesome. How many solar panels do you have, and how much did it cost you?

This is me. We installed the panels about 3 years ago in DC - installation prices have come down a lot since then and there are now myriad financing/lease/other options that didn't exist back then. We also went with SunPower panels (higher cost but more efficient production). I believe we have 23 panels (totaling 8.2KW) on an unobstructed rowhouse rooftop.

Total installation cost ~38k
30% offset by federal tax credit in first year (~11k)
Electricity cost savings (all electric house) ~1,500/year
SREC sales ~4,500/year (this may go down in future years, the DC SREC market is a little bit unstable)

The recurring annual savings/income is about 15% of installation costs, assuming the SREC market holds and no increase in electric rates, which gets us to breakeven in year 5+/-. It's not the most lucrative thing you can do with your money in pure investment terms, of course...

With solar, we produce more than we use in the summer months (but have electric heat/hot water so do not have a net negative electric use over the entire year).

NP.. so, do you get billed at all during the summer?

Our's is about $170/mo, 2400 sqft house. Temp set at 77.

I'm the PP with solar - yes, we basically net to zero electric bills from April-November, including the fixed distribution costs from the electric company. Keep in mind that the amount of sun in any given month impacts production (ie, there's less sun and therefore less solar production in October compared to June/July).

In 2016, our total bill for each of those months was:

April $4
May $-7
June $-16
July $-31
Aug $11
Sept $16
Oct $19
Nov $1

That's awesome. How many solar panels do you have, and how much did it cost you?
