Yes, I’ll be back to seal return.
Yeah the Schrader valve when you unscrew that top one sounded like it was leaking just so you know might want to replace the Schrader valves on that unit
@@andyvitz but pressures were fine, so ... maybe not as long as caps seal the valves
recommend ,return vents above the doors ,that house is at negative pressure,and it will struggle with no returns.
@@MariosACandRefrigeration All you have to do is take an inch off the bottom of the doors, if that's the case.
@@jthonn most new doors have a 1 inch piece of press wood on the bottom,for support.
There might be a problem when you walk up and the compressor sounds more like a vacuum pump 😂, that sounds is cavitation I believe.
clickety clacking away she was...
Good little vid Curt ... How bout them Vols ⚾Champs ... Thx
Another fur coat coil but of the evaporator type. Awesome job done as usual Curtis!
Was that a Compressor or a Popcorn 🍿 Popper ? 😬👍
Looks like someone was living in the package unit.. Nasty!
A whole family! Nasty for sure, and unhealthy.
The beginning conditions at 3:20 are ridiculous once you see the condition of the indoor Coil at 8:23. That amount if blockage should make the coil freeze up. The ending low superheat at 14:56 indicates that the metering device must be an orifice. It's likely that someone previously overcharged the system to address a persistent icing issue due to very low airflow. Therefore, it's essential to check the external static pressures. Sealing the return might further reduce airflow.
It's also highly probable that the system is too large for the home. A smaller, properly sized unit might be a better match for the current ductwork.
Been there done that. Suit up, put on your gloves and tape your wrists and ankles and wear a a good quality filter mask. Don't forget to spread some bait when your done.
I really enjoy your videos. Stay safe.
Those are (were) my favorite compressors. Very bulletproof. Great video. Thanks for posting.
They are good, as soon as I saw it, I said there's another big red.
Some critters for sure, she even said so. I never heard of keeping the doors closed because of varmints before. There was something rattling in that compressor that did stop, weird, but we have all heard some weird stuff in units and compressors before. It has got to be cooling much better now. As someone has stated before, there sure are lots of package units in your area. Nice job
Good job Curtis
that system is overfilled. Someone added refrigerant to get the suction pressure up and never looked at the plugged evaporator.
Great job,Curtis!
Thanks
We bought a Victor Rat Trap that is powered by "C" Batteries, and it sure gets the job done! There was an opening in our Log Garage from the outside that they found. It was killing one or two per night. There are no poisons for the Cat to get into! No more problems this year 😉
Somebody left the winter blanket on, on the evaporator.
Because the evaporator coils are always wet with dew when in operation, any filter leakage causes a problem very quickly.
Finished just in time ☔. That coil was filthy even had a guest rat😂...Saludos Vato
Saludos
Those damn things go through expansion valves like crazy. I bet I've changed 15 or 20.
Another save by HVAC GUY! Thank you Curtis
You bet!
Yeah, another slam dunk.
Another great save!
.
Use fiberglass filter? Where you were measuring liquid line temperature and pressure was before the condenser. Did it have a pressure port after the condenser?
Yes
That thing was a vacuum cleaner! Sucked up all in sight😊
A much cleaner coil now Curtis 👍 Au
That compresser sounds like it's overfilled but I don't see it sweating.
It's when you are in a slight rush you faulter. Today is it " About to rain on me.. " - the other vid when you tried to go fast to save the Church some time/hour rate. Heck we all do it.
That return flex should be replaced. That dust indicates rodent damage.
Great job!
I find the ones that have the coil outside the house with the compressor interesting. I take it it is always temperate climate there or something. Cannot imagine that in a place like Bismarck North Dakota. You would have tons of cold air coming in from that opening.
Nice work Curtis.
Thanks!
Looked like fluffy been living in there
I am supprised the evaporator is not froze solid. and the charge numbers looked good? thanks Curtis
There's gotta be a rat living in that duct work. That was nasty. I'm surprised a coil that dirty didn't effect the pressures too much. You should have told that lady that closing doors isn't going to keep the critters out. Rats can squeeze into wherever they want. Give her a good spook. lol
Good Job!!!
Thanks!
@@HVACGUY how many calls you usually run a day
3:20 shows you,there is more to this,then nice gadgets.
Exactly
that poor coil still looks dirty afte rbeing cleane dI had a rheem package unit i eventually was able to get rid of and get a regular split unit with a heat and a gas furnace
You would assume low superheat with an evap wearing a fur coat
Good job
why would my superheat drop when it was normal before the clean?
Didnt know trane used those popcorn compressors GE puts in all its fridges.
That compressor sounds like it has some ball bearings in it
The compressor sounded like it was shaking an aerosol can.
Maybe she needs to adopt a young barn cat who has been taught by Momma Kitty how to kill quickly and that the prey is food.
Cats don't need to be taught to hunt or kill mice. It's in their nature. Mine is 14, and had never seen a mouse til about 16 months ago when a family of them found their way into my house. It took her about 3 weeks to get all 9 of them. I haven't seen one since.
@@jimdavis6833 All cats will hunt, yes. Barn cats are particularly efficient about it, and don't leave little carcasses to rot under the couch.
@@jimdavis6833dont take life so serious bud. of course onusbones knows that cats can hunt lol
@@OnusBones My cat personally delivers the carcasses to me, even in bed. She never chews them up, just worries them to death, then deposits them where I'll be sure to find them.
@@jimdavis6833 Your kitty is trying to teach you how to take care of yourself!
Hey HVAC Guy! I have a question for you. Can a double breaker auxiliary heat strip kit be wired using one breaker or one side of the heat strip, instead of both breakers.
in this situation wouldn't it make sense to put filter inside package unit instead of at grill - protect the coil in case of return duct leakage.
Rats not a mouse
need to pull a new return duct too and clean the cond coil...
I still don’t understand why you use that foam gun. The coil cleaner is supposed to be put on as a liquid so the foaming action pushes the debris out of the coil.
Doors need to be kept open in this case.
Someone ran that unit without a filter for a long time.
There an animal somewhere in there
Yeah for sure, and it has a huge passageway right into the home's interior. I'll bet that sucker has chewed a hole part way between filter closet and the compressor unit, allowing detours into crawl space and framing. Nasty.
Sounds like non condensibles in the compressor?
Sounded overfilled to me too but the compressor wasn't sweating.
non condensables in the compressor Hows that work???
@@richardbartlett6932 well something like air is not generally excepted to be run through a an AC compressor. Things like contamination of moisture is not going to condense the way refrigeration has been designed to condense.
How does a coil get that dirty if a filter is being used?
because of that hole in the return, it sucks unfiltered air through any gaps or cracks.
A clogged filter will buckle and let dusty air in contact with the dew covered evaporator. The dust and water form a mud that becomes even more insulating when they dry. Doesn't take but a week for a leaky airfilter to cause a problem with the evaporator.
mickey mouse.
Open air return somewhere!
Wow! Complete blockage, that won't make it cool... Any bird or rodent nests.... Have you ever seen anything like that before?
Ugh that filter.....to thick for that return as it was just sucking it in!! Maybe a regular filter would be better? Take care and I appreciate the video!
Doesn't matter how thick the filter is. Once it clogs it will buckle and let dust collect on the evaporator.
So you’re saying you can’t restrict airflow with a filter that is to thick or has to high of a MERV rating for the CFM’s needed?
You need to change your brand of coil cleaner
yep, that was a really poor attempt at cleaning the coil...cover it with soapy water and leave it. You could see the foam on the ground was clean with no dirt dragged out the coil so it's doing nothing. The finished result was still surface dirty so it'll still be plugged .
Hi bro
What's up?
@@HVACGUY nothing much it is so hot here
AND to finish a proper cleaning job on the coil.. chemicals aren't cutting it, looks like a fin cleaning tool is in order..
That coil cleaner is useless, it's just foamy soap. . Buy some decent stuff that actually gets the dirt out.
Get both coils properly clean, upgrade or repair the ducting then pull the charge and weigh it back in..
hmm i see that my comment was deleted😆
12 subcool and 11 superheat before clean
10 subcool and 0 superheat after indoor coil clean
overcharged, but i dont think outdoor coil clean would make any difference
probably the last guy did a gas and go to get suction pressure up, vs. find and fix the issues. it's on the right track now *pun intended*
