Removing- 2x4 5 ft long

Loading- Make the supplier store do it on new equip
improper lifting with the assist of the dolley - change outs

Looking at the operating procedures, it doesn't say anything about purging the lines, of air, before recovering freon. Is there something im missing or just crack a connection?

Went to do a bid the other day. This is what I found on a 37 year furnace. Tri level home with main return in bottom bedroom behind the tv, behind tight louvered door, under stair well, through 1/3...

This happened in 2008 in my area. Couldnt find a cap anywhere.

Thats will they're high static systems. Can we say Tornado type air flow, LOL Our average temp here in summer is about 98* and 1 to 3 weeks of 110+

Nordyne has 14.5

I just watch some Yellow Jacket videos and they use their crt when using their vacuum setup

Thats weird. All my nordyne Ah has the txv already installed on the indoor coils. Even the old R-22 ones. THese are all Kelvinator units

The picture I posted is a variable speed AH and rated for a 16 seer system and its a standard tube/fin design with their special coating. It might be different from supplier to supplier.

I just almost had the same problem on a nordyne hp in cooling mode. But.mine would go into suction at compressor. HPS did not trip. indoor Txv went bad.

This is from the new b6 series from nordyne. Its not a mc but what the call there ant eater coil. Has special coating to block the corrosive.

AHRI shows the same seer rating for goodman thats using a orfice or txv.

I just checked out the microchannel coils for Nordyne. What a nightmare. Im doing a new construction job right now and am planning on installing a nordyne system. Looking at they're "quick data...

If you look closer, the zip tie is just holding the black insulation over the sealed end of the line set. Havnt sweated the connection yet. Waiting for the follow up appointment to finish it out.
