Heating and Cooling

  • Turn the thermostat down during winter and up during summer.
  • Open curtains or shades on the south and west sides of your house on sunny days during cold weather.
  • Close curtains or shades on the sunny sides of the house during the day in hot weather.
  • Close curtains or shades at night during the winter.
  • Run paddle fans clockwise on low during the winter to circulate air, and counterclockwise during the summer (when in the room) to feel cooler.
  • Check ductwork on the HVAC system for leaks. Patch ducts with metallic tape or duct mastic.
  • Change your air filter every one to three months.
  • Make sure the fireplace damper is closed when not in use.
  • Install solar blocking film on windows.

  • Drain your water heater once each year.

  • Collect rainwater from gutters in rain barrels for watering plants.

Further Learning


  1. Thank you so much for the information about closing heating/cooling vents. Since this house tends to h/c unevenly on one side, I really have tried that.

  2. The draining of the Water Heater is not wise as the build up that you are cleaning out will clog the rubber seat and it will leak.

  3. connect microwave to a surge protector with a switch, and turn it off when not in use. Who needs another blinking clock in their kitchen? Same goes with TV, DVR and other electronics. Also put your lamps on a timer, so you are sure they are off during daylight hours. And check with your energy company for the “peak” hours and do your laundry during “off peak” hours. Look around, your house is full of places you can save money.

  4. Watched your show this morning (9/26/16) and where do you get those gasket inserts for your outlets? Husband tried to find them but we need a correct name and location to purchase them.

  5. I own a second-floor condo that was built in 1986 and is subject to blistery cold Colorado winters. The walls appear to have very little if no insulation and the wall behind my bed in my main bedroom gets extremely cold to the touch in the winter and I can feel cold air entering through the wall sockets even after installing foam gasket inserts. I recently had new windows installed throughout in an effort to help with the energy bill, and now I’m looking for a solution to insulate that wall in my bedroom. I’ve looked into having insulation blown into the wall, but that is a very expensive process and requires patching holes left behind in the wall, yet one more expense. Can you recommend an affordable solution?
