Why Running Your AC at Night Is Not Always Cheaper


Common Air Conditioning Myths Debunked

One of the most persistent myths we hear at Wighton’s is that running your air conditioner exclusively at night will always save you money. While this seems logical due to cooler nighttime temperatures, the reality is more complex than you might think.

Why This Myth Exists

Many homeowners believe that since outside temperatures are lower at night, their AC units won’t have to work as hard. While this can be true in some cases, several factors affect your system’s efficiency:

  • Thermal mass of your home
  • Daily humidity levels
  • Insulation quality
  • System maintenance status

Instead of focusing solely on nighttime operation, consider these proven strategies:

  • Regular maintenance checks
