Jersey, I'm sure glad they did put ours on a separate breaker. In all honestly we are confident with our geo installer and their knowledge. I truly believe these systems are quite complicated and as Ladia has displayed over and over again with his knowledge things can and do go wrong. And, boy, are we learning here. Yes, I sure wish I would have disconnected those strips sooner (or been more persistent on the geo person that there still lay a problem besides the transformer replacement by the electric company) and not waiting for their staging question to be answered. Our system was a newer line so I'm sure there is some learning for the tech too. I sure hope I don't get another surprise next month like I did this month (I have even been reading the electric meters and right now my hubby has had to reset the compressor by turning the thermostat off then back on a few minutes later and that seems to reset and the geo then works fine--hardly hear it running. BUT, by far this is a temporary fix until next Monday by the geo people. I will note their findings (so future homeowners who are looking at geo have light of problems many of us have had and learn from our misfortunes.
Typical geo heat pump has about 400% efficiency (It doesn't make heat it transforms high volume of low intensity heat to lower volume of higher intensity heat.). So if it would work correctly your electric bill should be about four times less.
