It’s much more laborious for your system to achieve a consistent setting for many hours. It can also cause a lot of strain on your system, since it’s constantly turning on and off.

So, on top of it increasing your utility bills, it could also lead to a reduced life cycle for your air conditioner.

Regardless, the larger the difference between your indoor temperature and the outside temperature, the more your AC costs will be.

6 Approaches to Boost Your Air Conditioner’s Energy Efficiency

During the summer months, it’s recommended to set your thermostat at 78 degrees when you’re home and 88 degrees when you’re out. It’s additionally important to avoid setting your thermostat to a colder setting than usual when you turn on your air conditioner. This doesn’t actually cool down your residence any sooner, it just leads to more expensive utility bills. While these temperatures could feel high, there are many approaches to keep comfortable without having to constantly run the AC unit.
  2. Use Fans, Curtains and Blinds. ENERGY STAR says dialing up the thermostat by just 2 degrees and using your ceiling fan can lessen AC by up to 14% during the course of the summer. It’s important to note that fans cool people, not spaces. So, when you leave the room, turn the fan off to save energy. Also, keeping blinds lowered and curtains drawn during the day helps keep cooler air inside. There are also some window treatments meant to deliver extra insulation and enhance energy efficiency.

Caulking or weather-stripping are easy mends for leaks or drafts around windows and doors.
