Defrosting the Freezer

 


It is that time of the year again.  We had a coldish day we were able to put out freezer items out on the porch.  The freezer really needed it too!

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.

New Furnace Time

 My furnace has been leaking water out the bottom for awhile.  I looked at it and it appeared to be coming from the heat exchanger, so eventually I thought I would have someone come look at it.  I chose to go with the company that installed it, since I didn't want to get a fly by night low cost to inspect an arm and a leg to fix.

It was a Trane XR90, 92% efficient furnace.  It went in with the house in 2009.  Chuck came and assessed the situation and determined it was in fact the heat exchanger was no longer sealed.  The furnace has a 20 year warranty on the heat exchanger, so I was able to get the part for free, but the labor to replace it was going to be about $1000 he thought...

So I inquired about a new furnace, he recommended a Trane S9V2 which is 96% efficient with 2 stages of heat for $5500.  There are some rebates involved and my Trane discount which knock it down another $825.  So I went with that option just so I don't have to worry about it or deal with more parts failing.

I also asked for the Heat Exchanger as that is an expensive part, and I figured they owed me that and I might be able to sell it.  I also called around and received a lower bid, which they agreed to match ($5080).
