What do you mean by less efficient? If they're both done electrically, they're the same process, just moving heat in the opposite directions. If done with gas, you can't cool anyway.
Cooling in Chicago is through a lower temperature difference than heating. So heating will use more power. That's because the average temperature is below human comfort level. https://en.wikipedia.org/wiki/Climate_of_Chicago#Data https://en.wikipedia.org/wiki/Climate_of_Chicago#Data
- slfnflctd 7y agoRunning the compressor in an air conditioner takes a whole lot more electricity than running a blower fan to move air across some gas heat. If you wanted to break the whole thing down into physics, I'm not sure exactly how it would go, but at least in terms of market prices I can assure you it is much cheaper to heat a home with gas from 40 degrees F to 70 than to cool one with A/C down to 70 from 100.
- s_gourichon 7y agoSome refrigerator designs work by burning gas. The core principle of a refrigerator is to use energy to move heat from one place to another. One classical source of energy in such thermodynamics context is to give oneself a hot spot and a cold spot. Heating gas can be used to make the hot spot. I remember using on vacations in the 80's a model that could work with 220V, 12V or gas. More on https://en.wikipedia.org/wiki/Refrigerator https://en.wikipedia.org/wiki/Refrigerator
