In circumstances where cooling is needed in only one room, it may be preferable to install a single AC unit to serve that room, rather than create a new zone for a central AC system.

Hydronic heating systems are among the most efficient in heat distribution; a unit that combines both hot water and home heating reduces equipment purchase and installation expenses.
Some dryers do not make efficient use of the energy they consume. This is especially true of older models, and in homes with large numbers of people and laundry.
Dirty filters restrict the airflow of your heating and cooling system, making your system less efficient and increasing the system's energy demand.
Refrigerant coils, located at the back, are designed to remove heat. When dirty, the refrigerator cycle runs longer and more often; dirty coils can require as much as 25% more energy to function properly.
Whether leaving the house for a few hours or a few days, there is no better method for eliminating costs for heating and/or cooling when not in the house than simply shutting the system off.
The unwanted escape of heated or cooled air is often one of the greatest causes of wasted heating and cooling energy.
Blocked intakes and vents cause electric fan driven systems to work harder and heating and cooling systems to work longer. Moreover, blocked intakes and vents can cause combustion systems to build up unsafe amounts of explosive or harmful gasses.
A programmable thermostat will reduce the amount that your heating and/or cooling system runs unnecessarily, such as when the house is predictably unoccupied or at night when occupants are asleep.
Traditional incandescent light bulbs consume a lot of electricity; wasting much of it. This is especially true in large homes, and in homes with large numbers of occupants. Newer bulbs, such as Compact Fluorescent Lights ("CFLs") consume one fifth of the energy used by traditional bulbs. Switching to CFL bulbs is one of the lowest cost ways to get huge savings on your electricity bill.
