A programmable thermostat adjusts the temperature automatically when you are away or asleep to conserve energy and save money on your utility bill. One of the easiest ways homeowners can conserve energy, save money, and help fight global warming is to use ENERGY STAR qualified programmable thermostats.
An average household that spends more than $2,200 a year on energy bills can save about $180 a year by properly setting its programmable thermostat and allowing it to maintain those settings.
Puron, the brand name for R-410A, is the new non-toxic, non-flammable refrigerant of choice. Units using Puron are more efficient and less costly to operate. R-410A has been approved by the Environmental Protection Agency (EPA) to replace Freon and reduce environmental damage. Freon will become increasingly expensive to replace in existing systems. In 2010 it will be totally banned in new systems.
