Geothermal HVAC is like a heat pump that uses the constant temperature of the Earth. Ours is forced air & no it does not produce as hot of air as oil or gas (something like 110 instead of 115?). It works in cold climates & like any heating system, it runs longer when it is colder but certainly not 24/7. You also get cheap air conditioning. I can crank up the A/C & my electric bill hardly notices. For three months a year in the winter, we pay about $100/$135 more a month for electric but then again, I'm not paying the oil delivery guy $500 every time I call. Geothermal HVAC is far far far more efficient than oil or gas or electric. If your relative had problems it could be his unit was not properly sized. We have a closed loop system running off of two 375 foot holes. We don't burn oil or gas & don't have to worry about having a fume problem & killing everyone. We don't have explosive gas piped into our house or sit on 275 gallons of diesel fuel. Really, just because it is green, it will even work for the right wingers out there & save you money.You are an idiot if you pay extra for stupid "green" anything. I would like to know what kind of geothermal HVAC you have. Are you talking about re circulated ground water? I have relatives in northern Indiana that have that kind of system and they say it is not very efficient. They wish they would have put in oil.
That's the way I understand it. It's kind of like a heat pump where you barely get luke warm air. If it gets real cold outside, it runs 24/7.
I'll keep my natural gas furnace. When it turns on, you get hot air coming out of the vents.
