Is anybody familiar with Earth to Air LLC company? They are a newer company but I cant seem to locate a DX installer for the more familiar ECR Tech in my area (north central PA).
TIA

You can call EarthLinked yourself for their dealer near you. Their number is 1-866-211-6102. EarthLinked recently changed its name from ECR Technologies, Inc. to EarthLinked Technologies, Inc. This was to stop confusion between them and another ECR Industries.

EarthLinked is a very good product. If you don't want to call them to find a dealer, I'll find one for you. Just let me know.

As for Earth to Air, please read my post in another thread about them: http://greenbuildingtalk.com/Forums/tabid/53/forumid/13/postid/34354/view/topic/Default.aspx

Hopefully this guy's close to you. He's in Lawrenceville, PA.

It's Bing Hughes with Advanced Air. Phone is 866-423-8247.

Living in CT, and looking to have a DX geothermal system put in for heating, cooling and hot water. I believe in the system but I can't find anyone that has had problems or the down side of a geothermal heating system. I need to know what to expect on the down side. Does anyone have any feedback

I'm sitting here contemplating your question. I'm not seeming to be able to think of a downside.

About all I can come up with is the downside of it being installed incorrectly. Call EarthLinked Technologies, Inc. and ask who's the dealer near you.

I guess one other downside--and it's only a temporary one--could be that it can tear up your yard a little for a time. But yards can be put back together somewhat easily. Especially when you get all the benefits of geothermal in your home.

Another temporary one could be the up front cost. But really, what else are you going to put in your home that pays you back as much as a geothermal system? Along with giving you the ultimate comfort!

Where in CT do you live?

Brainstorming some potential downsides:
-biggest one in CT is probably cost of electricity - in New England there are areas where you need a COP of 5 or even 6 to beat natural gas, though gas isn't available everywhere. Make sure you get an accurate analysis of relative operating cost with current energy prices.
-in the event of a power failure you will need a _big_ generator (I could run my old oil burner off a car battery and inverter, my heat pump would need a 10kW generator)
-disturbance to ground, though it can be a good excuse for new landscaping
-electric service might need upgrading (primarily only an issue in old houses)
-people constantly bugging you to see your system and explain how it works

These are all pretty minor - the bottom line is if the economics work out and you can hook up with a good installer, there's no reason not to do it.
