We’re writing this on a day so humid that Pennsylvania feels more like Louisiana. Air conditioning is keeping us cool, but the world outside is grey, dreary and sticky.

A few weeks earlier, a different story. Breezy, warm but not too hot, clear blue skies. The ideal summer day. Perfect summer weather like that is hard to come by.

Creating the perfect summer climate indoors is much easier. Read on to learn how to achieve ideal coolness in your home this summer.

What’s the ideal air conditioning temperature?

Thermostat set at 78 degrees for optimal air conditioning in Summer

In an ideal world, we’d tell you to set your air conditioning to 78 degrees in the summer for optimal comfort and efficiency.

However, we recognize this may not work for every home or family, due to factors like:

  • The layout of your home – If you spend a bulk of your time in southern-facing rooms, you may want to keep things cooler than 78 degrees.
  • The time of day – Keeping your home cool when no one is at home can seem like a waste of money (more on this below)
  • Humidity levels – High humidity in the summer might encourage you to run the air conditioning more than you’d anticipated. You can control humidity in the summer by investing in a de-humidifier, or by running exhaust fans in the bathroom, kitchen and laundry room.

What’s the best air conditioning setting when I’m not at home?

You can save money in the summertime by keeping your house on the warmer side when you’re not home. Raising your thermostat setting by seven to 10 degrees when you’re at work – or any time you’ll be away for two hours or more – can cut your cooling bill by as much as 10 percent.

You can save energy when you’re not home by installing a programmable thermostat. This will allow you to set your air conditioner to a warmer setting while you’re at work – or a cooling setting during the winter – while still ensuring an optimal comfort level at home.

Keeping your home cool without overworking your air conditioning

You might think that 78 degrees is too warm to keep your home cool. However, there are steps you can take to keep cool air in and warm air out, thus ensuring your home remains comfortable:

  • Use window treatments to block the sun and keep heat from entering. (By the same token, you can leave your curtains and blinds open in winter to add some extra warmth to your home.)
  • Try not to use appliances that generate heat – like your oven – until after the sun starts to set. It’s summer, so take advantage of grilling season if you can.
  • Install ceiling fans and replace old air conditioning units with newer, energy efficient versions
  • Replace your old weather-stripping and put caulk around windows and doors
  • Dress for the season. Before you crank up the air conditioning, see how you feel by swapping your pants for shorts.

It also helps to make sure your air conditioner isn’t working harder than it has to by scheduling regular maintenance. If it’s been a while since you’ve had a heating and air conditioning professional look at your system, contact All Seasons Comfort Control.
