Our customers seeking heating and air conditioning repair service in Raleigh NCand the surrounding areas often ask, “Is there a rule of thumb for how many energy is saved between summer and winter by raising and lowing the set-point?”
Here’s our simple answer: “Save MONEY on every DEGREE.”
Energy savings are typically 2-4% for each one degree difference in thermostat settings within a 24 hour period. Therefore, you can estimate your savings by changing the set-point during unoccupied periods in which the prorate charge is simply the percentage based on the number of hours of setback and setup. Here’s an example:
If you raise the cooling set-point by 10 degrees for 12 hours, the estimated savings would be anywhere between 10-20%. How is this calculated?
2%/degree * 10 degrees * 12 hours/24 hours = 10% savings
4%/degree * 10 degrees * 12 hours/24 hours = 10% savings
Remember that these are percentages of your electrical use not of your overall electric bill total.
Also, keep in mind that your savings is reflective of your climate. Milder climates offer greater savings in comparison to harsher climates and, of course, you may see variations in savings depending on other factors such as insulation.
