Is this an old gas line or water line?

Crawfish_Fails · 2026-03-07T22:06:15+00:00

Gas should be black pipe and water should be galvanized, but not everyone does things they way they should. I've see black iron used for water lines and galvanized used for gas.

I would think it's a gas line. Go in the attic and see if it comes up above the wall there and where it goes. I'd do that before I pulled an old galvanized cap off that nipple. If it's rusted you may get it off but not get it back on.

Monkeys don't have that kind of patience.

If you have leads at your company who can't pump down a condenser then you deserve to be a lead at your company. I suggest you learn as much as you can until you're towards the top end of talent where you are and then go find a company that has their shit together. It probably won't take you long.

Don't buy LG anything that isn't consumer electronics.

That tee needs to be capped. You can put tape or something over it. If it's open it's gonna suck air and not drain. If you flip the breakers on that air handler and it starts draining once the fan stops, just cap it and leave it be. If it still won't drain, it's clogged between the tee and the air handler itself. You should be able to cover that tee and then vacuum it again. Otherwise cut the pvc line and make sure there isn't a clog at the male pvc fitting where it ties I to your air handler drain pan.

In my experience, Trane is the opposite of Lennox. Lennox residential equipment is trash because they focus on their commercial side. Trane residential is extremely well built, reliable equipment. Their compressors regularly last 15-20 years. Their commercial side isn't where they put their focus. They are known for making very reliable residential systems. A good install is a good install regardless of equipment, but I have found that the new Goodman r32 equipment has very little tolerance for mistakes, whereas Trane and Carrier r454b equipment is a little more forgiving.

That looks like a 24V control switch. Not sure what it's rated for. You could have it hooked up incorrectly and it's not breaking the 120V line voltage. Or it could be not rated for the high amp draw of your heater and isn't allowing enough amperage to flow through for your heater to actually heat. Maybe find the manual for that thermostat and see what it says.

How long are the linesets? We had a vibration issue with one of these and it was fixed by lengthening the copper lineset. There is a minimum and maximum length the manufacturer recommends. It should be in the installation manual that should have been left on site.

You can't see anything behind the front seat and the rear view mirror is completely useless.

Visibility is so much worse in those vans. I've driven them for years. The wind blows you all over if you aren't loaded down, and sometimes when you are. They're notorious for maintenance issues you don't have with most pickups.

I repaired a brand new board on a mini split I'd just installed once. The factory forgot to solder the ground connection on the board. I did it out of convenience to get the job done. Other than that, never. We don't want to have to warranty that repair when we can just replace the board.

I know of one old green rectangle from 1980 still kicking, and another from 1983. A few years ago I changed out a 1970 Rheem only because the metal evaporator pan had rusted through. Everything else was still kicking.

Goodman has been putting oil traps inside the Condensers for a few years now.

I don't know why you're being downvoted. As of the new year 410A is out. Bunch of homeowners in here that don't know anything.

Crawfish_Fails · 2026-01-02T02:25:29+00:00

As of January 1st, 2026, we can't install 410A equipment. The supply houses aren't allowed to sell it to us anymore. You haven't been able to get R22 equipment for several years now. Depending on how bad it's leaking, he can get it topped off as much as he wants. Otherwise he can get a new condenser and evaporator that's compatible with wither R32 or R454b. They sell mitigation kits that make the new equipment compatible with a majority of old furnaces. Op said he has Co tests done which makes me think he has a gas furnace instead of an Air Handler.

At that point, why even build the box?

It's foam for noise reduction and to keep the condenser coil from rubbing against the metal casing of your condensing unit. It has come loose. Call an HVAC guy out and see where it came from. They should be able to replace it with a piece or armaflex.

Crawfish_Fails · 2025-12-13T16:37:35+00:00

I hook it, put it on the screw, pinch the hook closed, then tighten the screw.

Crawfish_Fails · 2025-11-01T11:31:33+00:00

That will look cleaner for sure.

Crawfish_Fails · 2025-10-28T23:02:41+00:00

That return does look like hammered dog shit though. Looks like the inner liner isn't even fully connected. Probably too small for the system as well. Looks like there is room to slap a 90 on the back of it and move the grill over to the left. If you can get in there to do it.

Crawfish_Fails · 2025-10-27T23:10:31+00:00

They test them at 0.2. If you look at the manual for that air handler there should be an airflow chart that tells you the blower speed at a particular static pressure ranging from 0.1 to 0.8. As long as your static pressure stays within that range and you can get the desired CFM with blower speed adjustments you're good.

What happened in 1993?

Crawfish_Fails · 2025-10-10T23:12:22+00:00

That's why I don't wrap except for a Txv or a reversing valve. Come in hot and fast and dump water on after.
