ROANOKE, Va. -

Half of the energy used inside your home is due to the heating and cooling systems.

Greenway Energy Management Solutions says there are things you can do yourself to help save energy and money.

Using a programmable thermostat can save you nearly $200 every year in energy costs. This system is best for people who have a set schedule and are away from home for long periods of time.

Many people go wrong by never replacing their air filter. You should check the filter every month and have it changed between 30 to 60 days, especially during the winter and summer months.

Make sure you're having your HVAC equipment tuned up yearly and seal your heating an cooling ducts. This can improve efficiency of your heating and cooling system by as much as 20%.
