Quick Tips - Heating and Cooling


Reduce the biggest energy consumers in your home

Your heating and cooling system uses more than half of the energy in your home. A few changes in your heating and cooling habits can put more money in your pocket each month. Here are a few tips:

  • When you’re home during the warm months, set your thermostat between 78 and 80 degrees. Raise it seven degrees when you leave for a few hours. Raise it four degrees higher when you go to bed. During the cold season, set your thermostat between 68 to 70 degrees, when you’re at home.
  • Use a programmable thermostat. Set it at a higher temperature (try 85 degrees) while you’re away. Then, program it to be at a comfortable temperature (78-80 degrees) when you return. Consider one of our energy-saving options (link to Programs under Energy Efficiency)
  • Check your air filter every month, especially during the summer and winter. Replace it when it’s dirty.
  • Have your heating and air conditioning system inspected and cleaned twice a year by a licensed professional.
  • Replace your air conditioner, if it is 10 years or older. Consider a new, more efficient model. Take advantage of CPS Energy’s Air Conditioner Rebates. When buying a new central air unit, remember that proper sizing and quality installation are critical.
  • Repair leaks in your air duct system.
  • Reduce air leaks and prevent unnecessary air infiltration around the house. Add caulk around window frames and weather-stripping around door frames.
  • During the summer you want the fan to blow air straight down, so your ceiling fan needs to run in a counter clockwise direction (as you look up at it). The warmer it is, the higher the speed should be. During the winter, your fan should run at a low speed in a clockwise direction.
  • Check the insulation in your attic. The recommended level for an attic in South Texas is R-30 to R-60 (the higher the R-value, the better your attic resists the heat and cold). Take advantage of CPS Energy’s Attic Insulation Rebates.
  • Replace old windows with ENERGY STAR® windows. Cut your energy bill as much as 15 percent.
  • Install solar screens and solar film on your windows to reduce heat infiltration.
  • Plant trees and shrubs to reduce direct sunlight on your home and its effect on the temperature inside your home. Take advantage of our Green Shade tree rebates.
  • Install inexpensive foam gaskets behind the face plates of all electric sockets and light switches.
