Advice for Santiago Chile

I have been a digital nomad/full time traveller for over 9 years. I always thought Chile was more chill and now that I am also older and more chill I wanna go, one issue I am scared of that other parts of south america have...not proper heating. I have frozen my ass off in Colombia and Brazil since they don't have proper heating and I get cold super fast. I know Chile gets cold especially at night. Do some buildings have central heating? Do most airbnbs that have heating listed use space heaters? Any advice with this would be really helpful, I will probably go around Sept/Oct and stay 6 months.
