Is it a good idea to switch to geothermal air conditioning if your monthly bill is already low? Our expert Dan Danowski has the answer. Video Script: Oh hey, welcome to Ask the Expert. I'm the expert, Dan Danowski with IWAE.com. The question comes from Duffy in South Carolina: I own a house in South Carolina, but we only visit a few times a year. I spend $40 per month on the air conditioning to keep from getting mold and mildew. I'm interested in possibly going to geothermal. Would this be a good fit and make sense economically?

Ok, so $40 is cheap. That's a really low electric bill. So, if you get a geothermal, you could save money, but it's probably not going to make enough to make a difference. Even if you save 10%, that's like $4. If you save 25%, which is big, that's like $10. So like if you run it for 400 years, maybe you'll make enough to make sense of it. No, I think you're good, you're doing ok. I know my neighbors would murder a hobo to get that.
