Just finished install today! Contractor worked miraculously fast on my timeline. I got a similar quote from Dandelion for $85k. I'm not sure why my quotes were higher than most people's online, but I have a two zone setup with split units both in my basement. Assuming a single, packaged unit would've been cheaper, but I wanted to keep my two zones.

We chose water-to-water in order be able to use our existing cast iron radiators in an antique home. It has taken some effort to identify some very small leaks in the old radiators, which were causing air to get into the system, but once that was ironed out, it has been working well. The biggest challenge was getting all the tradespeople lined up. If one was available, another wasn't. Shipping delays and price increases over the last year also caused delays. It's not a process for the faint of heart, at this stage.

Ron is a very good geo installer, responsive, knowledgeable. I wanted to find a Long Island installer for WaterFurnace, but after repeated calls and msgs, they never got back to me so I went w/ Ron and his company. Climatemaster is a good 2 stage heat pump too, reliable, not as much telemetry metrics to monitor vs WaterFurnace. I also evaluated Dandelion, wrote a review on reddit here: https://www.reddit.com/r/geothermal/comments/qbkaa4/comment/hhjg95d/?context=3 and decided against using them and glad I did since they have gotten out of the market of retrofit geothermal in Long Island https://www.newsday.com/business/dandelion-geothermal-w63o8zz1

The Climate Master unit is great and the phone app gives you great information but the thermostat on the wall is pretty useless. It has a giant screen but will only show you the indoor temperature. Weather, set point, time, etc… are shown one at a time on a few second loop in 8 point font
