Top 6 Energy-Saving Home Improvements
$$$$ Big Ticket
$ Less Pricey
1 Windows/Doors
$$$$ Replace single-pane windows with dual-pane models that have high-performance glass. New technologies can cut you heating and cooling costs by 10-25%
$ Install interior storm windows to reduce heat loss; plastic sheeting sealed tightly to frame is the most affordable option
2. Water Heating
$$$$ Replacing older units with Energy Star models saves an average of $76 per year; tankless water heaters cost more but deliver up to 30% more savings than standard natural gas units
$ It's easy and effective to add an insulation blanket to most standard water heaters
3. Heating/Cooling (HVAC)
$$$$ New Energy Star furnaces and AC units are much more efficient than older units; it may be worth replacing one that is more than 15 years old
$ Replacing and/or cleaning air filters regularly could lower your bills by 5% or more. Install a programmable thermostat to automatically lower the temperature 10-15 degrees for 8 hours per day, and you'll save as much as 10% per year
4. Insulation
$$$$ Installing insulation within the walls is an elaborate project that may require the services of a contractor
$ Adding insulation to the attic is fairly easy and inexpensive; eliminating drafts can be as simple as sealing holes or cracks with caulk or applying weather stripping around exterior doors
5. Appliances
$$$$ Replacing washers, refrigerators, and dishwashers is quick and easy but can be costly; you can save an average of $34 a year in energy costs for each new Energy Star model you purchase
6. Lighting
$ When replacing old lights, use Energy Star qualified fixtures. Compact fluorescent light bulbs (CFL) last longer than standard lights and each one will save you $30 over it's lifetime - LED products last longer and use even less energy
