Furnace Install

 My installation date is Friday the 13th :)  Good thing I am not superstitious.

2 man crew arrived at 8am, and finished about 11am.  They said they would be done by lunch and they were done by lunch.  The new unit slipped right in place of the old unit.  It is a little smaller actually so they had to add an air flow box underneath.  Which I guess helps with the air flow anyway, because they are building furnaces so small now that there isn't enough space for the return air to enter anyways.

They pulled my A-coil out and I was a bit concerned to see all the rust on there.  I guess that is pretty typical though.  Something about how they don't build them like they used to.

Here is the new one, you can see the airflow box underneath.  I need to clean up the humidifier tubing and wiring.  We hooked up the 2nd stage of heat to the nest, though I can't really tell much of a difference in the fan speed between stage 1 and 2, apparently you can tinker with the CFM setting for the fan, but I haven't gotten there yet.

When I just run the fan it is very quite though.  I think it runs at about 30% of full, which is very quite and uses about 200 watts instead of 600 to 800.  So I might consider leaving it running, but I have never really needed it.
