Not to mention how would placing a recently driven vehicle in the garage, dramatically affect the inside temp of a home?!!

$118 set on 77 with ceiling fans moving air. Set it any lower my lungs fluid up.

Heats up garage which radiates heat to inside of house and attic is my guess?

The inside of my garage door is presently 116 degrees. The door from the garage to my laundry room (interior side) is 78 degrees (as measured with a laser digital thermometer). Next time, soon after parking my car inside, I'll do an experiment and check. My guess, the result would be neglible.

Your CYV is older, does it have thermopane Windows?
The other thought is if the AC unit is older it may not be as efficient as a newer unit.
Has your AC unit been checked out it may be low on refrigerant.

Up north set at 80. Bill was $68. For a Lilly

I don't know what that is but I want one.

No question about it the new AC units are much more efficient than an older unit. OP, your husband may be correct regarding an older AC unit. Our designer home (one year old) SECO bill for 5/26 -6/27 (32 days) was $70.14. Thermostat set at 78 and I believe humidistat set at 50%. Very reasonable.

LOL. I got mine at Lowe's for $29.99. Caution though, you find yourself checking the temperature of everything! Walmart has them as well.

Total energy cost for our Laurel Oak, 2540 sq ft, 7/15-6/16 = $1809.09. Total energy cost NY home 7/14-6/15 = $5978.29. Lots of variables, but substantial difference---I'm not going to worry if it's $20 higher next year

Our designer home averages 27 kWhs per day for the entire year.16 kWhs per day are what I call "baseline" (everything but HVAC). HVAC averages 11 kWhs per day for the entire year.

Our designer Ivy (2600 sq ft) runs about $150/month.
Our Tampa house used to run us about $500/month.
Another reason we love T.V. 😉

According to med research the best temp for sleeping is between 60-67, I would like it lower than 69 we use, but I don't want to go to battle stations with the admiral

What Planet
 

What planet am I living on? Designer home 77 during day and 70 at night. March bill $82, June Bill $267. Called SECO to ask what
is going on and then looked at prior years and they ran the same as this one. Called A/C guy and had the unit examined inside home and out and his conclusion all is running fine. Called SECO and told them to forget it as it looks like it is normal. (In fact in a prior year, same period price was $20 higher.) Will wait until it drops dead and then buy a more efficient unit.:popcorn:

A laser gun is a remote reading thermometer, used it a lot when we lived on a motor yacht to check engine manifold- & exhaust temps very useful tool, great when using a grill for pizza
