Your home’s heating and cooling systems might not be running as efficiently they it could be. Since Pacific Gas and Electric wants its customers to make smart choices managing energy costs, here is a short buyer’s information guide with additional energy saving solutions. While there is no rebate offered on these items by PG&E at this time, this guide can help you save energy and money for your home.

Central Air Conditioning: Get the Most Out of Your Cooling System

When it’s time to purchase a new Central Air Conditioning System for your home, look for a new ENERGY STAR® qualified Air Conditioner. These units can use up to 14% less energy than standard models, and can save you money throughout its lifetime.

Programmable Thermostat: Programmable Temperatures Mean Lower Bills

Programmable Thermostats automatically adjust your home's temperature. An ENERGY STAR® qualified programmable thermostat will change your home’s climate to a temperature you select, saving you energy and money when climate control is not needed.

Energy Efficient Heat Pump: Effective Winter and Summer

Did you know an Energy Efficient Electric Heat Pump costs about half as much to run as an ordinary gas furnace? Whether the outside temperature is warm or cold, an energy efficient electric heat pump circulates the air evenly throughout your house while moderating your home’s temperature.

Energy-Efficient Ducted Evaporative Cooler (EEDEC): Cooling On a Budget

An EEDEC may be a viable option and an economical alternative to conventional central air conditioner because of California’s relatively low humidity. Here are some important facts about Energy-Efficient Ducted Evaporative Cooler (PDF, 118 KB) that can help you choose the type of unit to install in your home.

Smart Buyer’s Tip

Consult a few contractors and get a few proposals for different energy-efficient solutions. Call the Contractors State License Board at (800) 321-CSLB or visit to confirm your contractor's license status or for a licensed contractor in your area.

Maintenance Checkup: Keep Your New System Running at Peak Performance
