You're rumming an AC? Sounds like it needs a good cleaming.

I'll interpret as I speak Squid: Clean the unit- youtube videos. Dry clean, then wet clean. delicate parts. messy.

If needs a charge (compressor runs) they need to add ports, i don't like saddle valves- braze is more gooder.

Rusty, I agree. Maintenance should be relatively easy, not made more difficult. (Detroit, do you hear that? I like being able to find parts on my vehicle. Please don't make it more difficult.)

I see. Warranty? or Craigslist? Did you put a thermometer in the outlet? Does it sound laboring or funny? Is it plugged in? Is the dial set all the way to: cool?

Did your post get cut-off? : It barely puts​ out any air and i...

It does sound a little labored. What would the thermometer read? And i guess i got cut off. And it sounds funny is what i was attempting to say. I hate typing on my phone

From the Windows down it is. Several of the Windows are covered by sheet steel. Great point. This one point is huge

Well, if it were me.... And it was Father's Day...

I'd head down to Harbor Freight and pick up several of their quilted moving blankets, hang them on the walls to create a thermal barrier...

Not just for testing purposes, but great to use year around for various things!
I use my Camo pattern a lot, and they're damned cheap!

Shoot, with some paracord and a few trees.... Instant survival shade

I have a second unit in the back (of the window type.) im pricing spray foam to insulate between the Windows and the steel. And in the ceiling. Any suggestions on foam type?

Check outlet temp, my old RV AC would deliver 20* under ambient. Never was impressed.

Have you pulled the front grill off yet to check for any packaging materials that might impede the fan or block the air movement? Keeps them from bouncing around in shipments.

Yea. The fan pulls across the cooling find instead of push tho.

is the issue that the air isnt cold or that there is very little air volume? what brand and model is it?

most rooftop units move decent air.. (air volume will feel similar to a window unit or car A/C vents)..

the air temperature on a spot unit like that should be 20-25 degrees colder than input.. run the unit for 10-15 minutes..
put a thermometer on the air intake, then on the vent closest to the coil.. (be careful about sticking the thermometer too far into the vents you can contact the fan or coils)..

if you have very little air volume and still not a good temp drop.. maske sure nothing is impeding the fan.. fan speed on most of these is important as its a single motor for outdoor and indoor fans.. as well as you need good airflow across the outside coil.. the lid needs to be secure on the outside of the unit.

It starts out cold and then starts to warm up. I then run just the fan for about 10 minutes, after that it blows cold again. inspection shows ice on the copper leading into the radiator (evaporator?) not sure of its nomenclature. I'm not an a/c guy.
