Split System Not Cooling Having Multiple Issues | HVAC

I'm running on fumes on this last service call. I always forget how this time of year can get with these attics, but you gotta try and keep your composure and stay on point either your diagnosis. HAVE A GREAT 4TH OF JULY EVERYONE!!!!!

That is actually a pretty nice attic for a low pitch roof. I have been in some that you have to belly crawl and lay in front of. Low pitch attics are hot because you are right against the roof. Not uncommon to find larger size air handlers than the outdoor unit in the south especially goodman, helps meet seer rating and dehumidification. Just ask your local goodman rep.

[@AB_HVAC]

I'm so not used to seeing the mismatched tonnage. My tech school up north taught me to only ever undersize the evap coil by like a half ton for better dehumidification. I've been in worse attics down here but none at this time of day.

[@AaronPowellvox]

@@AB_HVAC @myHVAClife is right. For some reason they do that a lot with Goodman. Sometimes it’s like that from the factory, you’ll call and ask for a 2 ton system and you’ll get a 2 ton outdoor with a 3 ton evaporator.

[@AB_HVAC]

@AaronPowellvox that's so dang confusing

[@joeshearer1247]

Your eyes must be getting tired that’s not a Goodman air handler.

[@MetalDetectingwithCZkidd]

S FL famous for belly crawling.

[@jph77]

I'm from the south and have a walk in attic from the upstairs bonus room.

[@AB_HVAC]

I love those kinds of attics. Better have that OSHA approved platform 😅

[@justwork_hvac]

Cool video, brother. Be safe in those attics they are rough around this time.. i just used that leak seal the other day..

[@AB_HVAC]

I'm a fan of it, it works either way honestly. Shows you where the leak can be if it can't seal it

[@MoonRambo702]

I’d use that same ladder just the shorter one, versatile. I feel u on the basements tho, I was spoiled in Michigan, now I’m in Vegas with these hot ass attics and nobody has a pull down. Ladder needed for every job.

Man, we used to just walk down a flight of stairs, move some totes around and boom got room to work 😅

@MoonRambo702 🤣🤣 man me and my old bosses had to do some townhouses over off Woodward in highland park. My old boss called me up (owning and working at a new company now) said all the furnaces and condensers were stollen.

[@MoonRambo702]

@@AB_HVAC 😂 always the neighbors. It’s a huge problem. bro they watch y’all put em in and call the boys the min y’all drive off. It happened a few times to me on the east side. The mgt co. I was working with started having me take the tanks, furnace and ac units to storage, and put em back the day ppl move in. And they have like 3 sitters that are homeless and move em around to nicer vacant properties. They clean and keep up the house too while it’s waiting for a tenant.

[@AB_HVAC]

@MoonRambo702 🤣 I still remember putting in those units like it was yesterday. Lots of ductwork and pvc being rand for those 90% 'ers

[@Devsfan70]

People in other parts of the country just don't understand how hot the South gets. I've lived in Georgia my whole life and still hate the summer. Good AC is a must. 🥵

[@AB_HVAC]

I been here for 5yrs and it's getting hotter and hotter every summer it feels

[@Devsfan70]

@AB_HVAC you're probably right. The older I get, the less tolerance I have for it. I just try and limit going out to do anything in the early part of the day. Yeah it's still hot and muggy but it's not a peak heat.

[@AB_HVAC]

@@Devsfan70 yeah. I had to swap a gas valve in a low pitch attic on Tuesday for a home up for sale

[@patrickbell4687]

I can see in the video it has has to be hot as he'll in that attic. Make sure sure you stay hydrated during the day, especially in the summer. Stay healthy!!!

[@joshmason1725]

I use a little giant king kombo , its light, and unfolds from a 6ft to a 10 ft, they have many sizes...so I recommend a cordless m12 Milwaukee fan .

[@chrisscott1547]

In my experience, leak sealers can work OK on slow leaks (makes them slower) but if refrigerant is gone, you'll get a callback. Oversized evaporators can work OK, but may want to reduce blower speed. Attic work this time of year earns a surcharge...

[@jkmarshall3553]

For hard work like that, I'll take cold any day over that heat!

[@MetalDetectingwithCZkidd]

Good find on the wire. I would cut the KW in half if the wire size was not sufficient. Then tell the customer to get an electrician out there to change the wire. Most of them were reminded when it got cool out and the house was not heating properly. Disconnect did its job, sort of. To small wire = fire. 10KW at 240v and 8KW at 208v I think is how it works, however, wire a #6, always for anything with 10KW, breaker and fuse size very important as well. I know the heat in attics, S FL was a roaster up in there. The AC was a mix. Carrier AHU with a Goodman Condenser. Zombie AC. If in doubt on the size of the Evap coil, pop the panel and see if there is a manuf tag on it. Usually its there. Nice vid. Enjoyed.

[@redneckways1617]

#8 isn’t big enough for 10 kw heat strips and the blower…needs at least a #6 or unhook half of the strips which you can’t do cause that’s the only source of heat…your only option is to replace the wire with a #6 then run it off of a 50 amp breaker…still has a leak somewhere…that’s the best design for a rental property cause it’s the most reliable but personally I would opt for the inverter heat pump…runs a considerably less amp draw for the same load….

[@RidingWithRamsey]

Looks like the classic loose lug on the disconnect. Although the wire size is cutting it close.

[@AB_HVAC]

After stripping it back I was leaning towards the incoming power being 6gauge while the whip was 8gauge but I'll wait till it gets approved to dive deeper into it

[@techfive7202]

In Florida I call that a really nice attic

[@AB_HVAC]

130° or the size 😅? I just didn't like the way the access hole was.

[@myHVAClife]

Can't pull a vacuum on a unit with a leak, will suck in humidity through the hole. Can't add sealant because it will react to that moisture and create restriction. Need to fix the leak and with a goodman it is probably the evap coil.

[@AB_HVAC]

It's not a Goodman match indoor but I can try and use a lil 410a vapor and then pressurize more with nitrogen to find the leak with my fieldpiece leak detector

[@ccthepope]

Have a great 4th!

[@AB_HVAC]

@@ccthepope You too!!!

[@Dmcbigboy8687]

8 gauge wire is good for 40amps and 6 gauge is good for 60amps. I think the 8 should be ok for 10kw heater but would like 6 gauge to be much more safe.

[@tphvac87]

410A is garbage wish the EPA just stuck with R-22 now we got this new higher pressure trash R-32 and R-454B they just keep screwing us over, mildly flammable gas that runs at same pressure as 410A. Wild stuff man! Let’s replace a TRUE refrigerant with something that runs at double the pressure and leaks a lot faster than 22. Idk what they’re thinking? Lemme know what y’all think?

[@AB_HVAC]

I wasn't around enough with R22 systems to truly be able to compare the two. But I do find a lot more customers say they were happier with their R22 equipment than R410a

[@jrsmyth9761]

per the install instruction, minimum wire size for single feed is 6AWG. minimum 60 amp breaker/fuse. max wire length 80'. leak seal should be a last resort and ALWAYS mark the unit, in multiple places, that you put that crap in. I, for one, will not connect to a unit that has that crap in it!!! I will buy a set of gauges and hoses that is charged to the customer if I run across a unit with leak seal, UV dye or similar product.

[@danielzertuche9893]

Your HEATH is more important and your safe too first thing in the morning.

[@BallSnack5.56]

I've never heard of the right hand rule??? Only rule i followed when taking out disconnects was to make sure i was not leaning on the unit or touching anything with my other hand.

[@AB_HVAC]

Right hand so if somethings not wired properly the voltage won't go through your heart just the right side of your body down to ground...I think

[@BallSnack5.56]

@@AB_HVAC Well that makes sense, i'll have to try to make it a habit of using only my right hand then, the more you know haha

8 gauge wire can hold like 50 amps max I think

@@coastalcarolinarocks yeah I think that 10k around 60. The incoming wire had to be 6 gauge. Was a pain to strip back and had thicker strands of wire than that 8 gauge had

Attic air handlers should be illegal anywhere south of Ohio. LOL

[@gund89123]

I have air handler in garage. I am upgrading my home. My HVAC contractor was suggesting that we should move the air handler to attic, I said no. I live in San Jose, CA. It gets hot here in the summer.

[@AB_HVAC]

How can we make this federal law 🤣

[@AB_HVAC]

@gund89123 maaaaaan keep that thing in the garage 🤣 any service tech (and probably future installers) will love you for it. Just make sure it's sealed tight so that way if you use your auto start it's not sucking up exhaust fumes into the air stream. I heard that's a major reason why they try to move them from the garage
