Compare your answers to the correct ones below. Give yourself a point for every correct answer and write that number down.

1. B – Turning down your thermostat 1 degree can save you 3% on your home heating expenses. (Department of Energy and Environment)

2. C – Approximately 48% of families in America use natural gas to heat their homes. (Climate Central)

3. D – Ductless mini splits don’t generate heat – they move it from one place to another, which uses less energy than other forms of heating.

4. D – Air source heat pumps can keep your home comfortable down to – 13 degrees Fahrenheit. 

5. A – Central heating systems produce the same amount of air regardless of which vents are open or closed, so you’re not saving any money on energy. Plus, you can negatively affect the static pressure in your air vents, causing damage to your heat exchanger and potentially resulting in hazardous gas or carbon monoxide leaks. 

6. A – True. Heating itself removes humidity from the air, which can aggravate allergies and dry out your skin. It’s important to monitor indoor humidity during the winter and use humidifiers if your air is very dry.  

7. D – Your air filter should be changed roughly every 30 days or so to keep your indoor air clean. 

8. B – Thermostats should be put in the middle of your house where there are no doors or windows where drafts could affect the sensors inside.

9. C – Pilot lights are used to ignite gas-powered furnaces used for home heating. 

10. B – False. Your thermostat should be set to “auto,” which allows your fan to turn on and off based on the temperature in your home. The “on” setting will run your heater constantly, which raises your electric bill and can make your home uncomfortably warm.
