There's an easy check for noncondensables get post count up and apply for pro.

Make sure the piston isnt clogged, but if it were your sh and sc shouldnt be in line. If it warms up any it will be bouncing off high limit.

I hope there are plenty of homeowners reading this post!
This is that guy who came in $1000 lower on a full system quote!
Now you know what you're paying for!

I hope your boss goes out of business for ruining my industry! Sorry about your luck. I would suggest finding someone else to work for. You are on a sinking ship!

Same thing at my company. After I wasted around 15 pounds from two different systems, they finally sent a memo out to all our installers.who cant read anyway. Big sticker right.next to service valves charged with nitrogen, remove and pull vacum then charge.. Lol dont.they get it dry unit....lol

I read your post and it made me cringe... I just had one of my guy's install a Goodman dry R22 unit. I told him about 8 times that there is no refrigerant in the damn thing and that he needs to let the nitrogen out then pull a vac then charge. This dullard went ahead and pulled a vac then cracked the valves releasing all the nitrogen into the system then turned the unit on... He sat there for 2 hours like a dope trying to figure out why the suction side gauge was pegged out at "retard". I told him that he's the reason why it says "retard"... I went out there and heard the compressor being tortured to death.

Sounds like noncondensables. Recover the system, pull a good vacuum, and recharge. Your boss should be smacked for telling to not do anything unless the customer says something about the noise!

I would say overcharged..

Sounds like non-connies also.

non condensibles.

They ship systems with orifices and txvs. If was new system why wasn't the factory charge adequate?

Not to sound stupid but from what i read he has a new 410a system and a new air handler,Shouldnt that be a txv not a fixed orifice.
and did he change the filter drier as well

I agree, first glance sounds like noncondensables

Overcharged

For that OD temp, the head pressure should be around 375 psi. Measure subcooling and see if it's not way high.

Remove some and tell us what happens ....

Balance the charge, all I install is Goodman and I've seen this more times than I can count.
