Done!

[bentruler]

Ok, they got done over a week ago, but I've been busy.

I know my installer posts / reads here, so...
2 zone 4 ton XM16i. Heating 3200+ sqft (like the sqft matters)

The first floor supply runs through the unconditioned basement. Its becoming my new wood shop, so I didn't want to ruin this with dust. Return runs throuh a line of closets.

2nd floor goes up through a closet to the attic and comes back down.

Some required shots:

Before stat:


And they (10+ of them) controled:


With a 15 month old... So off the wife goes for a week...
She took the camera with her, so I don't have any shots of what happened then.

So after a week:


I can't say enough how huge the 18" runs for the 2nd floor looked...


Now I do have to do a little shoe squeezing... I came home from work to find:


You see, the wife and 15 month old had come home the day before. The yahoo doing the electric (me) had pulled out all but two of the baseboard circuits when the lines for the heat pump got installed. So I was in hot water. I've never been so happy to have strip heat on one floor. I was so happy to see they hacked something together for the night... Saved my bacon.

Final wrapped:


Stat:


No picts of the outdoor unit, its dark out, and I'm cozy in the house. I'll get them tomorrow since I've got to wait for the electrical inspector.



I'd like to thank everyone who shared advice and comments with me and the other HO's. I learned a lot, both about the business and HVAC tech. Now I've got to convince my FIL to not take a per sqft bid on his new place.

What zoning system did they use?

By not using rectangular duct you wasted ALOT of space down there.

I have to ask...why would you install this in the vertical downflow position if all the ductwork is above it? It seems more logical to install it in the upflow position...much better airflow.

I like that thermostat. Does it come with an outside (wireless) temperature display too?

[seatonheating]

I must say that is an awesome install. Would love to see some more pics. Whoever did this work should be very proud of themselves. Must say, this is the best work I have ever seen. I'm blown away!

Not to mention waste of time wrapping all that pipe with insulation. Rect. duct with insulation on the inside would have been faster and saved much more space. Just my $.02 (my company has a sheetmetal shop so we do things that way all prefabbed from the shop)
