Regarding Luck_P’s post,

I’d be mindful of problems with freezing. If the loops are horizontal, perhaps there’s a fix that’s not too expensive – if you’re lucky.
If you have vertical bore holes, perhaps there’s a technique to determine which loop is defective and replace it with another hole. The problem has to be defective fusing of the sections of pipe. That being said, I’d be worried about when the next fusing will become defective.

I’d get quotes on what it would cost to put in a completely new earth link. I’d also inquire about warranties, reading the fine print, and ask how long these people have been in business. Ask for references where systems have been in service for 5 years and over – follow up with phone calls and visits! One more thing, I’d see if I could get the whole system (or should I say, ‘hole system’) covered by a home-owner’s insurance policy. Speak to an insurance broker who can get you the deal. It might be worth the premium on the premium!

Good Luck – Post an up-date!

BTW, my ground loops - 8 of them - are copper tubing filled with freon. I have a Direct Exchange or DX System - not your ground loop water system. My loops were put in drilled holes going down diagonally from the manifold.

Good luck.

SR makes a good point - for anyone else considering putting in a geothermal system - to check out any prospective installers. We were new to the area, and all we had to go on at the time was a list of 'authorized' geothermal contractors/installers from our electrical co-op. Just because they were on the 'approved' list, doesn't mean they knew what to do - or would do things correctly, even if they do know.
The guy who installed our system is now out of business, and we've come to find out that he more or less went out of business because he had so many lawsuits pending against him with regard to improper installations and system failures.
My loops have a leak, and in addition, instead of each unit(2.5 T downstairs, 2T upstairs) ecah having their own loop and pump, they're both hooked up to the same loop & pump unit.
Additionally, my upstairs unit blew 4 compressors over an 8 year period, and we finally bit the bullet and just replaced it - and when they pulled the old unit out, they found the installation directions insert booklet sucked up against the grille. I guess it had been there, impeding air flow since day 1, and in all the times the installer and his son(who joined another HVAC operation when his dad went out of business) had been out to work on it, they'd never figured out WHY it kept blowing compressors.
