Your House Temperature

Quick Question:  As summer weather sets in, what do you keep your thermostat set to?  I’m just curious how our 77 degrees compares to other people.  Also do you keep it constant (we do) or do you change it based on the time of day.


  1. Arjun Muralidharan says

    We keep it at a frosty 68… we have a geothermal heat exchange pump, which uses earth heat to heat the house and water.

  2. Jill says

    we do 77 too, and it is constant. Up in Michigan, it is not so much to get the heat out of the air at this time of year, but to counter the humidity.

  3. Mary Anne says

    Brrr! I don’t stop sleeping under two blankets until it’s up to 80. I keep the air conditioner (the new one with all the tech gadgetry) set at 81, which seems to keep the side of the room where the bed is a comfortable 85. The downstairs stays quite pleasant with ceiling fans when the outdoor temperatures are in the upper nineties.

  4. Mark Shead says

    @Joel – YIkes that is pretty warm!

    @Arjun – I’ve been looking at geothermal heat pumps. I really like the idea because it sounds pretty efficient. Are your AC bills pretty low?

  5. says

    I have one of those programmable thermostats that has “levels” throughout the day, currently:

    Wake (5:15): 74 – easier to get out of bed when it’s not freezing cold in the bedroom
    Leave (7:30): 82 – Not home during the day
    Arrive (5:00): 71 – Walking in to a cool house always makes me feel comfy
    Sleep (9:30): 68 – I love to sleep in a cold house!

  6. says

    Gotta love those programmable thermostats! We have 2 central units: one upstairs and one down). They are both set for 78 when we are home, 84 when we are not, and 81 from midnight to 6 am.

    Although we did bump both of them up to 80 this past weekend, just to get the units to shut off in the 100+ degree weather!

  7. Deb says

    We are in Florida & program our thermostats to 80 when we aren’t home, 78 while home & awake & 75 while sleeping (nothing worse than waking up due to the heat). We keep all of our ceiling fans on while at home to keep air circulating so it feels cooler than what the temperature reads. Of course, when it is 78 in the house and the heat index outside is 101 it feels pretty chilly when you first walk in.

  8. Jeff says

    Here in Sunny southeast Virginia, I keep my thermostat at:

    68 – Winter
    78 – Summer

    At the height of the Heating or Cooling season, my combined Electric/Gas stays below $200.00. Spring and Fall are the best. I might break $50.00. To be fair though, I do have a small house (1200 sqft) so that helps.

  9. says

    As of mid-May we turn off the heat and then do not use the air conditioner until the temp reaches at least 35Celcius(90 F)

    In winter (Canada) using a programmable thermostat it is 15C (59 F) night/day and 19C (66 F) for when we are actually in the house (before work and after work)

    If we are cold then just put on slippers and a sweater :)

    @Mark: The bills are yet to be seen, as we just bought a new house. The initial heating up cost us a lot, and the bills are high the first quarter.

    We’ll have to wait and see, but I expect them to normalize in a month or so. It keeps the house pretty well conditioned, as it has intelligent modes for summer, winter, night and pretty much manages itself. It also uses the heat emanating from the pipes of the house and reuses it.

  11. says

    We don’t have any options in “setting the thermostat” in the summertime. We live in an older house without air conditioning. Some demented former owner replaced the wood-framed, double-hung windows with aluminum-framed jalousies about 40 years ago (we estimate) and it would be totally impractical to air-condition the house without replacing all the windows first.

    I think a demented owner could only really get away with a stupid modification like that in a mild climate like ours (Los Angeles). Anywhere else, the first winter would be the last for those windows.

    At any rate, in summertime we have fans going all night to pull the cool air in, and then before it heats up outside in the morning we close all the windows and use the fans to circulate air inside the house. With the thick stucco walls, awnings on most windows, and the northwest-southeast orientation of the widest dimension of the house, the interior stays livable even when the temperature is 110 outside. Not chilled by a long shot, but livable.

  12. Adrian says

    Thermostat? When it gets hot[1] I open the window, when it gets really hot[2] I close the window and the blinds. Ah you crazy oil-loving americans, gotta be airconditioned all year round.

    [1] 25-30C
    [2] 30-40C

  13. Claudia says

    My husband and I like it as cold as possible without spending a fortune on heat and A/C.

    During the winter, we keep our house at 61F unless it is brutally cold, and then maybe we will move it up to 63/64F.

    During the summer, we keep it at 77F when we are out, 74F when we are home/awake, and 70F when we sleep!

    We have a HE system for both heat and A/C, so our average bill for electricity and gas is around $200.

  14. Quick Lunar Cop says

    In the summer:
    – 24C / 75F (day)
    – 26C / 79F (night)

    In the winter:
    – 21C / 70F (day)
    – 16C / 61F (night)

  15. Carm says

    We have no air conditioning for summer so just regulate with open windows and fans. In the winter we keep the temp at 65F.

  16. Carol (Texas) says

    I live in Texas and actually ran across this site researching. My husband and I are constantly battling over the thermostat. Our home is about 1200 sq. ft. ranch style older home. The ac/heat unit is about 6 years old. Our electric bills run between $225.00-565.00 generally higher in winter months. I’m very hot natured and want it comfortable to me when I’m home which is evenings so I generally turn it down to 74. He’s home all the time and cranks it up to 79. I think it would be cheaper to leave it at one temp and not go up and down. The house gets very warm past 77 (even to others). We’ve had it serviced recently and all is working well. We have very few trees around our home and live very close to power lines. I’m trying to come up with a solution for both of us to be happy and crank our utility bill down in this 100+ degree weather. Any ideas? What’s a happy medium that will prove to him our electric bill can come down and maintain cool? Thanks.

      Here are some suggestions that might let you keep it cooler without running the air-conditioning more:

      Make sure you have proper ventilation in your attic. If it is getting much over 110 to 120, you probably could improve things by putting in vents. You might even check into the powered vents that kick on at 110 degrees.

      1. If you have a dark roof, you might consider a lighter color–particularly a cool metal. We are in the process of putting on a reflective roof and initial tests showed a 10 to 15 degree difference under the roof in the attic where the metal roof was than where it wasn’t.

      2. Make sure your house is sealed as much as possible. Clear caulking around the windows can help a lot.

      3. Insulation in the attic and possibly in the walls might help too

      4. Grilling outside may help keep from heating up the house when you eat

      Hopefully something there will help. :)
