Places like Tucson, Arizona have extreme heat in the summer and places in Canada can often have extreme cold. Does a geothermal heat pump work in extreme climates? Video Script: Today's question comes from Sundai Mendoza in Tuscon, Arizona. Sundai asks, "Does a geothermal heat pump work in Tucson where the temp gets up to 110 or more for much of June to August?" The answer: Yes. You can put a geothermal heat pump there and it will be fine. You may think, but it's really hot, so certainly it won't work. Yes, but a geothermal uses a buried ground loop. There are a couple of other different kinds, but at the end of the day it's all about dealing with that buried subsurface temperature. And dirt is a really good insulator.

So, no matter how hot it gets outside or how cold, for that matter, if you're in Canada, a geothermal is going to do good and they're going to keep the same amount of efficiency. That's why they're so stable in terms of efficiency they save. They are always dealing with the same temperature. Under the ground. Where the corpses are.
