Hello Gary
Yes my utilities bill when down specially with the electric. It when down because I invested lots of $$$ over the years acquiring one or two at a time energy star appliances like the fridge, a gas range, washer and dried all energy star. Changed all lights in the house inside and out to LED, changed 4 window Air cons to 4 high efficiency Mini-splits Air cons which makes a huge difference. I change all cell phones from Claro to prepaid T-mobil got a special 5G data Unlimited Text and 100 min talk for $30 each plus tax at Walmart. Choice cable TV Internet and TV for $55 plus tax.
My electric bill for February 2015 is $142.85 for 640 kwh at a cost of .21 cents a kwh. I am planing on making further changes like installing a small solar panels systems to be used only with the fridge and mini-splits air cons. That will cut my electric bill even more but that is out in the next few years.
If you wish to install mini-splits air conditioners that are really efficient shop for: Misubishi Electric from Roger Electric, Trane from Home Depot, Panasonic from Oldachpr or Daikin from Airconpr.
