As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about your home's heating, ventilating, and air conditioning (HVAC) system can have a big effect on your utility bills – and your comfort:
- Replacing an old central air conditioning unit with a new, efficient model could cut your cooling costs by 30 percent. Sizing and proper installation of a central air conditioning system are critical to energy efficiency and home comfort.
- New furnaces that use advanced technology deliver higher efficiency than even standard models that are still available today.
- Features of new, efficient boilers that improve efficiency include electronic ignition, which eliminates the need to have the pilot light burning all the time, and technologies that extract more heat from the same amount of fuel.
- High efficiency electric air-source heat pumps (ASHPs) that use the difference between outdoor and indoor air temperatures to cool and heat your home use less energy than conventional models.
- Properly using a programmable thermostat in your home is one of the easiest ways you can save energy. The key is to establish a program that automatically reduces heating and cooling in your home when you don’t need as much.
