1. Check for wasting water: Leaky Faucets, Worn out Flapper Valves in the toilet, leaking hose bibs. A fast easy way to check is to turn off everything and go look at your water meter. If the water meter is moving you are leaking water.
2. Check for wasting A/C: First if your A/C filter is dirty change it, a dirty filter makes the unit work harder. This equals $$$. There is no fixed schedule for changing the filter, every home is different so a visual inspection will let you know when it is time. Second check for gaps in your windows and doors. The more gaps the more you are throwing away $$$ by letting the cool air escape.
3. Look at the location of your outdoor condensing unit. If it is in direct sun all day, consider adding some landscaping to shade the unit this will take some of the strain off.

4. Maintain AC system: Replace the filter and clean the coils, call a maintenance company for service regularly.
5. Seal Windows and Doors: If you are wasting A/C through gaps and leaks, and are not in the market for replacing windows right now, start with adding weather stripping, same thing if your doors has gaps.
6. Replace Light Bulbs with More Efficient Varieties. They are as bright as regular bulbs once they’ve been on for a minute. This is a huge one, it saves us so much money each month!
7. Replace Appliances & Components with Energy Star rated units.
8. Replace or repair leaking plumbing: Change the washers, shower heads or toilet tank flapper valve. If you have a worn out flapper valve the tank is constantly leaking and thus refilling. Changing a flapper valve is easy. If you have leaking hose bibs and a traditional gate valve just tightening the screw that holds on the wheel can often stop the leak.
9. Add attic insulation: Check your utility company and see if they offer any incentives. Even without local incentives, adding blown in insulation is a relatively inexpensive method of insulating, and will save you a bundle on heating and cooling costs.
10. Paint: Painting your house a light color or even a reflective paint will provide an energy savings by taking some of the heat load off of your A/C.
11. Add Window Film: This is a very affordable option for reducing heat load into the home. If you can’t do the entire house at least consider adding window film to the west and south.
12. Landscape: The overall heat load on your home can be offset with strategic landscaping to buffer the house from the sun.
13. Add a timer to your traditional water heater. Set the timer to turn off the water heater while you are away at work all day and set it to come back on in the evening.
We have done a lot of these in our new house that is twice as big as our last house. Our utility bill is exactly the same here. So, these really do help!
