Keep Your Cool AND Save Your Money this Summer

Summer’s here, but while temperatures are rising, your energy costs don’t have to. Count on the experts at ENERGY STAR to show you how to keep your energy bills under control and help protect the environment all summer long. 

Keep Your Cool 2020




1. Maintain or Upgrade Your HVAC System

With heating and cooling costs counting for nearly half the home’s total energy bill - more than $900 a year— ensuring your HVAC system is operating at peak performance is the key to keeping cool this summer. Be sure to:

Check your air filter every month. If the filter looks dirty, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

Get an HVAC maintenance check-up. Just as a tune-up of your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Schedule an HVAC contractor to inspect your heating and cooling equipment. A typical maintenance check-up consists of inspecting system controls and components, and making sure connections are tightened and in safe working condition. Specific to cooling equipment, the contractor will inspect refrigerant levels and adjust them if necessary. They will also clean and adjust blower components and clean evaporator and condenser air conditioning coils.

Consider installing ENERGY STAR certified heating and cooling equipment. If your heating and cooling equipment is more than 10 years old or it needs frequent repairs and your energy bills are going up, it may be time to consider a replacement. ENERGY STAR certified equipment could provide dramatic savings compared to a unit installed 10 or even 5 years ago. Let the ENERGY STAR Heating and Cooling Guide help you navigate an HVAC equipment upgrade that will save energy, save money and help protect the climate.

2. Install an ENERGY STAR Certified Smart Thermostat

A smart thermostat that’s earned the ENERGY STAR is Wi-Fi enabled and can automatically adjust temperature settings in your home for optimal performance. ENERGY STAR certified smart thermostats have been independently certified, based on actual field data, to deliver energy savings. They allow you to control your home’s cooling remotely through your smartphone and quickly enter a low-power standby mode when inactive.

3. Choose an ENERGY STAR Certified Room Air Conditioner

Households without central air conditioning can save money using an ENERGY STAR certified room air conditioner. ENERGY STAR certified room air conditioners use 10 percent less energy and, on average, cost less than $70 per year to run.

Certified room air conditioners with variable speed technology save even more energy and quietly regulate the temperature, providing the innovation and energy savings you're looking for in a state-of-the-art room AC.

Be sure to properly size your room AC for comfort and savings. An oversized unit will cool the room but only remove some of the humidity, leaving the room with a damp, clammy feeling.

Stay connected! ENERGY STAR certified room air conditioners with connected functionality offer additional convenience, comfort and energy savings by allowing you to turn off the unit remotely using your phone or computer, schedule changes to settings based on your needs and receive feedback on how much energy your product is using.

4. Keep the Heat Out and the Cool In

Seal your ducts. Sealing and insulating ducts can improve the efficiency of your heating and cooling system by as much as 20 percent — and sometimes much more. Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house.

If your home experiences hot ceilings and walls, uneven temperatures between rooms or high energy bills, consider adding insulation in your attic. This will help maintain desired temperatures throughout your home and help lower energy bills.

Replacing your windows? ENERGY STAR certified windows reduce the "heat gain" into your home more than typical windows, without reducing the visible light. So, you can enjoy the sunlight, without the heat!

Close window shades and drapes in warm weather to keep out the sun's heat.

5. Be a Fan of Fans

Run your ceiling fan to create a cool breeze. If you raise your thermostat by only two degrees and use your ceiling fan, you can lower your air conditioning costs by up to 14%. Remember, ceiling fans cool you, not the room. So, turn it off when you leave the room. Need a new fan? ENERGY STAR certified ceiling fans with lights are 60% more efficient than standard fans with lights.

6. Look for ENERGY STAR Certified LEDs

Replace those old, hot incandescent light bulbs with much cooler ENERGY STAR certified LED light bulbs. ENERGY STAR certified LED bulbs produce about 70-90% less heat, so they're safer to operate and can cut energy costs associated with home cooling.
