Warm Days, Cool Nights: Seasonal AC Tips for Energy Efficiency

This is the time of year when those of us in the Chicago area can still experience some pretty warm daytime temperatures as our nighttime temperatures begin to get downright cool. Humidity begins to drop and the air starts to feel fresher. It can be tempting to consider turning seasonal AC on and off or to only use it as needed. We may even view it as a way to save energy. That may not exactly be the result. Here are some tips to stay comfortable in the fall, while also being energy efficient.

5 Tips for Seasonal AC Energy Efficiency

  • Let your thermostat do the work. Rather than turning AC on and off between daytime and nighttime, let your thermostat do the work and set it two or four degrees warmer. This will allow your residential AC unit to operate more energy efficiently while not having to work too hard to bring the temperature down inside your home during those warm days.
  • Use fans to circulate the air. With a higher thermostat setting, it may be a little warmer in your home during hotter early fall days. This is a great time of year to use your ceiling or oscillating fans to circulate the air. Since your AC will be operating less frequently, the fans can offer an assist in moving the air in your home.
  • Opening windows may not be the best idea. Opening your home’s windows can be tempting this time of year but if someone in your household suffers from allergies it could cause problems. It can also cause your air conditioner to work overtime if you forget to close them during warm days. An open window, even with a screen, can also be a security problem.
  • Change that filter. If you haven’t changed your air filter yet this summer, now’s the time to do so. Filters are inexpensive and easy to change and just maybe the single easiest thing you can do to keep your residential AC operating efficiently.
  • Check your outdoor unit. Fall leaves have a way of gathering around outdoor AC units. Be sure to make an occasional visual inspection of your outdoor unit making sure it stays unobstructed.

Turning AC on and off during the early fall can be tempting but it also can be hard on your equipment. By turning your thermostat up, using fans, keeping windows closed and maintaining equipment, you can get through these “tweener” months using your system efficiently.

Many times, a residential AC unit can limp into the fall, barely surviving the summer. That’s why this time of year is a good time to get an AC checkup so it will be ready to go in the spring.
