If you have not put a thermometer on the intake vent and a vent output one might be surprised by the increase in cooling with cooler temperatures. Also if duct work is in the attic there is a difference on a sunny day or time of day.
I would also like some type outdoor temperature or maybe cooling degree day each day. I also like the weatherunderground.
Ok i admit I am cheap or just not a lot of extra money to spend and am trying Sense to save money. Does it cost less to cool in the morning and then let it get warmer in the house during the day?
This is just a guess I have not done a great job tracking but, I can get up to twice the cooling in the morning before daylight compared to say 3pm.(I have an extra long return which done for looks and not energy usage, I am almost tempted to move it, but then I would have to add some extra vents.) And in the morning (70F) it draws about 2450 watts vs 2800 watts at 3pm, 95F. But so for Sense give an average wattage usage of about 2500 watts all the time and I also have two units. I was told a fix is on the way. Also how well a house is insulated would make a big difference. On the other unit it is like a 30% more efficient with lower temps.
Yes IMHO outside temp could be helpful in knowing if a unit needs freon or not, or that was my hope in buying Sense.
