You guys 'think' you got HVAC troubles

So, this week, "the end of" my part of getting my Dart painted, is installing the OD unit for the neighbor's AC/ furnace

And.......everything fell to you-know-what

First, Lowe's screwed up and sold him an oversized unit. Instead of noticing that his 30 year old furnace was a 65--70% AFUE and downsizing the new 80% plus unit, the sold him a new unit with more heat OUTPUT than his old one. I under--fired the damn thing to keep it from short cycling

And, (we didn't know at the time) due to old remodel, some of the ductwork is "marginal"

======================

On to the AC............

Lowes sold him a 3 ton (36000 BTU) when a TWO ton would have been more than ideal. The good news is they sold him and indoor coil with an external equalized TXV instead of an orifice

The BAD news is the cheap --*** Winchester condensing unit HAS NOT START relay. Like a window banger this means the damn thing won't start until pressures equalize, "not something you want" with a TXV

========================

ONTO the fireup..............

So I get things together, started up, and things don't look too bad. UNTIL I went to remove the gauges, THE LIQUID SERVICE SCHRADER is STUCK OPEN!!!!!

This would not normally have been a big deal, except I yanked out the disconnect, shutting down the compressor. I probably SHOULD have just shut off the liquid line service valve and let it "pump down" right then and there.

=========================

So what we have NOW is.........

A liquid service schrader stuck open, and the gauges still hooked up

It still won't start

And have evacuated a recovery tank, tossed it into the freezer, and spend 3 trips 1/2 hour apart trying to get enough out of the indoor side to get the damned compressor to start again..........

I did not need this. I'm getting too old for this. Plus, I don't have a recovery machine "exactly designed" for R410. If you are not aware, it operates at about TWICE the pressures of R22
