Geothermal - Heat Pump and Ducting install

We still don't have a date for our electrical utility upgrade (from 150amps to 400amps), but I've been repeatedly told it should be about $1000. The HVAC contractor is getting antsy, and has had our equipment purchased and sitting around their shop for a couple of months now, so we are going ahead with the heat pump installation. Apparently we can run temporary electrical to test it out, and do final electrical (and inspection) later. Hopefully it all goes as planned.

The HVAC contractor showed up on monday. They're scheduled to be here for four days, but are hoping to knock it out in three.

They immediately got to work dismantling and removing our old natural gas furnace.

By the second day, they had the heat pump in place!

Here are some photos of the guts of the heat pump:

We got a Energy Recovery Ventilator (ERV) installed as part of this project. We are hoping to continue tightening up the building evelope, especially as we eliminate the need for combustion air for natural gas appliances, and the ERV will ensure we still get enough fresh air.

And finally, we have a steam humifier for the dry winters here in Colorado:

UPDATE October 2021: The steam humidifier does a great job keeping the humidity up, but it's an absolute energy hog. In the autumn, the steam humidifier is often using more electricity than the entire heat pump. I'm a little horrified to think how much power it's going to use in the winter. I'm actively looking into different solutions for humidity now.
