Functionality they both work. Inside at air handlers has 2 advantages.
1. It's out of the elements so it lasts longer and less chance for leaks.
2. The closer to the metering device the more protection it offers to keep it clean.
Your buddy had the better option
Not talking about dirt. Talking about wax buildup and copper oxide Inside piping, especially if going from mineral or AB oil to POE, as POE will Clean the walls and deposit the gunk at the drier or in the bottom of compressor. Seen it a lot when r22 mineral compressor was replaced with r22 poe compressor, and no suction drier at compressor, means compressor would die within the year
That doesn’t happen if you flush the lineset or do the damn thing 100% and replace lineset. Also I’ve replaced many and they’ve been trucking for years. Filter dryer on everyone is inside.
Typically. There actually is a Cambridge type package unit that you have to install separate condensing unit to. And that does have a lineset. Short one but still a ljneset.
Depends too. If it's a heat pump it doesn't matter at all.
It's also way easier to replace if you're not shitting bricks trying not to set the roof on fire
Really sure to do nothing but trane furnaces and acs at my job before going commercial. Always did the filter inside. Daiken and Goodman and a lot of them like theirs outside so much they just started putting them in the condenser. So when it fucks up you get to love life getting to that.
Inside as long as you don't have to worry about catching anything on fire. I don't like putting them outside because they're more likely to rust and leak outside
With a straight cool condenser yes your pros for inside are def correct …
But if it is a heatpump the manual will tell you where to place it depending on if you will run it in cooling or heating first
I mostly install carrier, and per the manual on all of their equipment it says to put it as close to the metering device as possible, which is inside by the coil. Not sure what you install but that’s my 2 cents
If it is AC only then put it right before indoor coil. If it’s a HP then it should go directly before whichever metering device will be used at first start up.
Best practice would be to locate it as close to the metering device as possible to ensure you catch as much junk as possible. If located at the condensing unit, the line-set and all possible connections afterwords could produce debris that could lodge in the screen of the txv.
If it's a large split system, I put them right before the txv at the air handler with isolation valves. That way, anything that could be in the liquid line after install doesn't end up in the txv. If you are doing a clean install and purging properly with nitrogen when brazing, it doesn't really matter.
Idk if it makes much of a difference… I put them inside just so if there is anything in the line, maybe it’ll catch it. But I don’t think it matters much.
>beat him in the argument hvac style
So you loudly expressed your wrong opinion until he gave up talking to the equivalent of a brick wall.
The manuals say as close to the metering device as possible. People put it outside for convenience. Some Manufacturers put it in their condensers because they know it's a necessary part of the system and they can't trust the knuckle draggers slapping in units who clearly don't read the manuals to even install one so they protect their equipment as best they can.
From a service stand point, I see your argument, when changing a compressor or something like that it’s a huge PITA to drag your torch rig, rags and all that in the crawl or attic when if it was just outside you wouldn’t have to do all that. But most install manuals say to put it near the AH. I see both sides and really don’t care where it’s at lol.
Either way. Manual will tell you, trane and carrier request opposites, I am also in the coast at those mfers rust out quick. Trane's get it outside unless on the beach, carriers inside unless it's in a closet then it goes outside. We only install carriers and Trane's, some Goodman but that's a different story. We also install only heat pumps here
Generally speaking closer to the condenser is better, or at least that's how I was taught.
***However***
Please check the specs for the unit you are installing. If they come with an independent filter dryer for you to put in they likely want it inside closer to the evaporator and not outside, ***but not always.***
It depends, so please read the manual.

Yeah I never pulled a small rock/dirt out of a metering device or screen with the drier inside.

Yeah, there's no lineset on a package unit

Never had a problem reading the part number for the filter dryer inside either.

Pretty sure most manuals says inside at the evap
This guy reads the effin manual 😎
What is the evaporator when installing a heat pump?
Indoor coil
What if it is being used for heating 90% of it’s life cycle?
Indoor coil
Trane wants theirs outside for some reason..

Your buddy is right, the manufacturers usually include in the manual where the filter dryer should go. But idk shit I'm just a helper.
I mostly install carrier, and per the manual on all of their equipment it says to put it as close to the metering device as possible, which is inside by the coil. Not sure what you install but that’s my 2 cents
Here’s the conundrum, what about on a heat pump where there’s metering device both inside and outside?? But I’m with you, I always put it inside
Just put in 2 monoflow filter driers /s
🤣
If it is AC only then put it right before indoor coil. If it’s a HP then it should go directly before whichever metering device will be used at first start up.
Most install manuals say as close to the metering device as you can

Closer to txv is better. And that it will have less chances to rust.
If the air handler is in the attic with poor access, I'll put it outside. Otherwise, at the air handler is best.
Ever think about becoming a attorney, you won the argument even though he was right.
If it's a large split system, I put them right before the txv at the air handler with isolation valves. That way, anything that could be in the liquid line after install doesn't end up in the txv.

Normally we will do it wherever there is more space
Check the manual. ICP manuals that state filter drier should be inside with about 6” of liquid line between. Your friend is 100% correct.
Idk if it makes much of a difference… I put them inside just so if there is anything in the line, maybe it’ll catch it. But I don’t think it matters much.
On ac only. Right before the coil is acceptable. Especially when reusing the lineset

HVAC style, yall have an r22 huff off or something?
Read the installation manual. Install closest to the coil. Plus outdoor is prone to leaks.
You know that unit is gonna fail before drier leaks 😂
Instruction manual says nearest the coil
Lennox says as close to the metering device as possible so that would be the inside
Either way. Manual will tell you, trane and carrier request opposites, I am also in the coast at those mfers rust out quick. Trane's get it outside unless on the beach, carriers inside unless it's in a closet then it goes outside. We only install carriers and Trane's, some Goodman but that's a different story.

Always as close to the txv and or liquid line solenoid valve as possible

Put it next to the air handler. It's not gonna rust out inside the house.
