A piston in a 2 stage will work just fine with a multi speed blower and proper airflow in both stages. I've done it too, to get by for a day or two, but was impressed enough with the results to leave...

Nice, most of my equipment is Copeland. It was a disaster!

No doubt it will, and adding a TEV would probably lower it even more. I just don't think the metering device is the saviour of a crappy installation. It's nothing more than a band-aid for the...
I have a 2003 Goodman split heat pump, fixed orifice metering device, with undersized duct, low airflow, crazy high static pressure, and absolutely none of the problems you guys listed. Still on...
How did you get through the Copeland rust inhibitors/coagulation debacle Without changing TXVs? My techs were changing 10 TXVs a day during that nightmare!

I installed one of the gps units, the iwave-r right before Christmas. I had a 8' tall Christmas tree in my living room, after installing the iwave i couldn't smell it anymore. I run my fan in the on...
I've been to a couple of the classes and i was impressed. Thinking about putting one on my house. If it's good, great. If it's bad, at least I'll get some experience working on it lol.

Nothing wrong with a Frankenstein capacitor, but there is a right way to go about it

Yeah the only shortage in our industry is pockets being lined with cash. Dont worry, wont be long some legislators will decide they need to make some $ and 410 will join 22. Then the companies they...
Love your username! In all seriousness that probably does play a roll too

There's more than one way a 4 way valve can fail, temp reading isn't always the answer. But you have to get creative to get temp readings. If youre a tech you'll figure it out, if not it's time to...
Im pretty sure anytime anything in our industry changes or gets more expensive it's the democrats. Usual excuses: efficiency, global warming, greenhouse gasses, etc... Then they'll make a special...
Coolwhip is right, it's the Democrats.

I 2nd that, you cannot accurately charge or even check a charge if you arent 100% sure the coils are clean!

Yes subcooling wil vary greatly with fixed orifice systems. Charge to superheat. The only thing you use subcooling for in charging is to prove you have enough refrigerant stacked in the condenser to...
In alabama they give you a list of code books and textbooks you're required to bring to the test. The catch is learning how to get through the books to reference codes and do load calculations while...
Ive used imported 410 for years now, no issues that I know of.

I would shoot for 10* superheat as well.

I would always advise replacing rhe drier when opening a system, its not like they cost a ton of $, they're definitely cheaper than callbacks

Does this unit have a piston or expansion valve? Superheat looks a bit high to me...

I wouldn't personally, but if unsure about the failure i would add acid treatment as a precaution. Or find out who diagnosed it and ask them

I have 13 service trucks and they're pretty evenly split between jb platinum and yellow jacket bullet pumps. I have no complaints with either. The jb rep is at our supply house occasionally and does...
The telescopic ladder and the mighty brace come to mind. Mighty brace allows one man to work on or replace wall mount minisplits. The telescopic ladder is great for those lovely attic access doors in...

Package gas unit, microchannel slab coil

I helped one of my techs replace the evap coil (microchannel) in a Maytag gaspack today and i was surprised at how difficult it was. He's one of my top techs and I'm the service manager with nearly...
Some people never learn. They'll probably do the same thing to the new equipment after the warranty is gone...

Good to hear! Glad I could help.

All the new mortex coils ive seen came with an expansion valve already installed. .068 sounds small to me. Grandaire 3 ton should either have a .073 charged to superheat or a txv charged to 10*...
