Savings to You

About Energy Management

Can I do this with thermostats and timers?
NO. Many people have tried and for many reasons you can’t. Most people throw in the towel due to the inconvenience and limited savings. Many of our customers are people who tried to do it themselves and called Advanced Home Systems to get results.
Is this a load controller?
Referring to the device from the 1980’s made popular by APS and the now defunct ‘demand advantage’ rate? Energy Sentry is NOT the same, as it is BETTER. Better in how it successfully keeps your home cooler and does NOT impact your use of major appliances like your dryer or hot water heater. Energy Sentry multiplies the value of a load controller without the headaches associated!


How long does it take to install?
Usually it only takes a week to 10 days. Since we’ve installed over 25,000, we have perfected installation so that a 2-man crew can complete the installation in 1 ½ to 2 hours –without stepping foot in your home.
Where is the computer installed?
The computer resides in a small protected service panel next to your electrical box, outside your home.
What does it look like?
Mounted outside of your home next to your electric panel you probably will never notice it. The box can be painted to match the color of your home to blend in. Go to: to view.
Can I take it with me?
YES. Since it can be reprogrammed, this is an investment you don’t have to leave behind when you move. Can’t do that with windows, air conditioners, insulation, roofing, solar systems or other home improvements!
