Summer in New England means trips to the beach, hikes in the mountains, neighborhood pool parties, and air conditioners working to keep our indoor spaces cool and comfortable.  

Here are some simple tips to ensure you’re using energy as efficiently as possible during the warm summer months, so you can enjoy the season to its fullest!

Use a Smart or Programmable Thermostat

Smart and programmable thermostats can help you control your air conditioning more effectively. These units are easy to install and can automatically adjust the temperature according to the schedule you program. 

According to Energy Star®, smart thermostats can save up to 8% on an energy bill by using sensors and automation to adjust to your habits and the changing weather. Programmable thermostats are not responsive to weather or occupant behavior, but can still generate savings. Massachusetts customers may be eligible for a rebate via Mass Save.

Optimize your AC

  • Clean or replace air conditioner filters regularly, and perform preventative maintenance on central ACs and heat pumps in accordance with the manufacturer's instructions. This will not only improve the efficiency of the unit, but will also prolong its lifespan.
  • If your outdated, inefficient room air conditioner needs replacement, look for an Energy Star-rated model. Massachusetts customers may be eligible for a rebate via Mass Save. New Hampshire customers may be eligible for a rebate via NHSaves, as well as an incentive to turn in the old unit for recycling. Explore room air conditioner tips here.
  • Be mindful of your temperature setting. Three to five percent more energy is used for each degree your air conditioner is set below 78 degrees.

Use Fans and Ventilation

  • In milder temperatures, ceiling or portable fans and open windows can cool down your home for less than a traditional air conditioner.
  • When air conditioning is non-negotiable, fans can supplement your AC’s efforts, allowing you to adjust the temperature on your thermostat by a few degrees, thereby saving energy.
  • Be sure your ceiling fans are turning counter-clockwise in the summer, creating a down-draft and cooling effect. Fans cool people, so remember to turn them off when leaving the room.
  • Kitchen hood fans and bathroom exhaust fans should be used when cooking or showering to remove excess moisture from your home.

Keep the Heat Outside

  • Air seal your home to avoid heat gain, allowing your cooling systems to work more efficiently. Common air sealing techniques include caulking cracks, adding weather-stripping to windows and doors, and adding insulation. Learn more about insulation and weatherization.
  • Close and lock windows when cooling your home. Install window coverings such as shades, awnings, or sun screens on windows facing south and/or west to block summer light.

Pump Your Pool Efficiently

  • Pool pumps use a lot of energy – in fact, they are usually the second largest electricity consumer in the home, with ACs or heat pumps coming in at the top of the list. To clean your pool efficiently, choose a pump that is sized appropriately for the size of the pool, and run the pump only as much as necessary. Find more tips at Energy.gov.

When Possible, Run Appliances During Off-Peak Hours

  • Peak demand is when regional electricity usage is at its highest level within a specific period of time. Summer peaks typically occur in the afternoon on the hottest and most humid days. Because electricity is primarily supplied in real-time, peaks can put pressure on the regional power grid. Peaks also influence overall electricity costs. Running appliances like dishwashers and laundry machines early in the day or later in the evening can help reduce peak usage. Learn more about peak demand.
  • Time-of-Use rates have different electricity prices based on the time of day electricity is used. Determine if TOU is right for you!
