Um no.
I work for a residential HVAC service and repair company. The single most expensive repairs (and most problematic systems) we routinely stumble across are geo thermal.
Compressors need to be special ordered as nobody around keeps them in stock. Turn-around time can take 1-2 weeks, and longer during peak seasons. Pumps are the same. And lord help you if there's a leak somewhere. I think the theory behind geo is sound, and there's a lot of potential there. But long-term it's going to potentially cost you beucoup bucks, especially if you're not an annual maintenance kinda guy.
Truth be told, I think 99 percent of the issues stem from improper installation. When geo was all the rage 8-10 years ago, every swinging dick with an HVAC license (and some without) wanted a piece of the action. Well, you get what you pay for. We have a customer west of DL who had a company install his Geo, then went out of business. Now he's stuck with an expensive system that kicks out error codes like a Bismarck bouncer, and is considering starting over with a standard forced-air system and air-to-air heat pump. QUOTE]
I think the industry evolved so fast that manufactures were in a big hurry to be the first to the market , Sort of like the snowmobile industry of the early 70s. Thinking back, I remember one manufacturer bragging up their new scroll compressor then about a month later they were in the process of a unit "upgrade" that consisted of a rubber mat to set under the unit on because of vibration issues. I toured the Hutterite colony in SD hoping they were building a down to earth affordable heat pump but instead they were more interested in promoting an expensive all Stainless Steel cabinet. The most important thing I know of is to get ALL the air purged out of the system during installation and use good makeup water with additives and corrosion inhibitors.
