There are many ways to reduce energy costs. The following could well result in possibly a 30% reduction in your heating and cooling costs so it is definitely worthwhile considering these suggestions:

An HVAC system that is older than 10 years is probably not running very efficiently. You should consider updating to a more energy-efficient current unit.

Insulation should always be checked and added at the beginning of the fall season.

Be sure that you have closed off the space between the foundation and cladding. Many overlook this area and it has the potential to be very costly.

Confirm that you have vapor barriers underneath the crawl space and over insulation in the attic.

If you have old and poor fitting windows and doors, consider replacing them with today’s energy efficient products. If this expense is not realistic right now, consider sealing up all of the gaps with caulk and hanging very heavy insulated curtains or window shades as a temporary solution.

Check for drafts by electrical switches and outlets and use additional insulation if necessary to prevent cold air from entering the room.

Check weather stripping and replace any caulking that is no longer providing the required seal.

Consider Energy Star appliances if you can possibly afford to replace the existing ones. If this is not feasible, be certain that you only wash full loads of dishes and clothing.

Replace air filters regularly as dirty filters will cut down on efficiency.

Consider investing in a programmable thermostat which will automatically set the proper temperature and eliminate waste.
