What Temperature Should You Keep Your House? | Energy Saving AC Thermostat Tips


Nobody likes being hot and uncomfortable when they’re trying to relax at home, which is why many of us have turned to Air Conditioners as the solution.  But what temperature should you set it to to beat the heat and avoid draining your wallet?  We’ve got a few suggestions and tips.

What temperature should I set my thermostat to?

When it comes to managing the temperature of your home, it can be a bit easier if you have a programmable or digital thermostat.  That way you have a bit more control and can program it to switch to different temperatures when you’re away from home or sleeping.

So which temperature is best?   While what’s comfortable for you may vary, Energy Star has a few recommendations.  When you’re at home, the recommended temperature to keep your home at is 78ºF.

When you’re away from home, you don’t need to keep your home quite as cool.  They instead recommend switching your thermostat up to 85ºF.  If you don’t have pets, you can potentially turn it up beyond that.  The closer the setting is to the temperature outside, the less your air conditioner has to run.

And finally when you’re sleeping, it’s recommended that you set your thermostat to 82ºF.

Making adjustments

We understand that those temperatures may not be comfortable for everyone so you may need to make a few adjustments until you find the temperature that is right for you.  When you do this, try lowering it one degree at a time until you find the highest temperature you’re comfortable at.  The reason for this is that each degree lower your thermostat is set can potentially cost you an extra 3% on your bill.

You should also avoid turning the temperature way down in the hopes of cooling things down faster, as tempting as it may be.  The truth is, it doesn’t actually speed things up and instead it just uses extra energy.

More Tips

We’ve shared some of these tips before, but we though it might be helpful to have them all in one place.

Open the windows at night – If it’s cooler at night and you don’t need the AC, open up the windows to let in the cool air. When it starts to heat up again and the sun comes out, shut the windows and close the curtains or shades.

Use box or ceiling fans – Fans typically use much less energy when compared to your Air Conditioner.  They also create wind chill which can help make you feel cooler even when the temperature is actually the same. Rather than turning down the thermostat, try switching on a fan while you’re in the room.


Energy Audit – Some energy or service providers can perform an energy audit in your home to help you avoid using unnecessary energy.  You can also perform a quick audit yourself by running your hand around the outside of your windows to see if air is escaping and to find out which ones need to be resealed.

Change the air filter – When your filter is dirty, it forces your air conditioner to work harder to cool your home. Changing yours regularly can help you more efficiently cool your home.

Window AC Tip – This tip is mainly for room or window air conditioners.  Instead of leaving it running all the time, try turning the unit on around 30 minutes before you plan on being in the room.  That way it has enough time to cool and you won’t be as tempted to turn the temperature way down.
