On days when you can’t escape to the beach to cool off, try these top seven energy saving tips to keep your home cool and save money for fun summer activities.

1. What are a few degrees?​

Running your air conditioning at 78°F instead of 72°F can save between 6 and 18 percent on your cooling bill.*

2. Re-decorate!

Placing lamps or TV sets near your room air-conditioning thermostat can cause the air conditioner to run longer than necessary because the thermostat senses heat from the appliances.*

3. Plug the leak.

On average, households lose about 20 percent of their heated and cooled air through the duct system to the outside. Find those leaks with a home energy audit through MassSave.

4. Use the dynamic duo.

Air conditioning combined with a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.*

5. Get a gadget.

If you have a window air conditioning unit, try a device like the modlet and control window AC units from your computer or mobile device. Technology like the modlet can save you up to $70 per unit or 466 kWh a summer. To cancel out the CO2 emitted by this electricity waste, you’d have to plant eight tree seedlings.

6. Install a programmable thermostat.

And save up to $150 a year on energy costs when used properly. Get one for free when you do a Mass Save energy audit. *


If every room air conditioner sold was ENERGY STAR, it would prevent 900 million pounds of greenhouse gas emissions annually, equivalent to the emissions from 80,000 cars. **
