To my understanding some of the coils would work on 3 up to 4 ton but I might be wrong.

[@Mitch2294]

Proper metering device is key. If the coil is starved Upsize the piston not the greatest for efficiency but you could probably make that coil work.

[@user-ip4ke7ki2u]

Wow I don't understand how and why most techs did even try to check data plate on both air handler and condenser unit. HVAC GUY your best please keep making videos. When I went to HVAC SCHOOL I learn a lot from you. I have since graduated and I am working on the field as HVAC tech doing service and maintenance on the field. By the way my favorite video is OMG possible lighting strike!!! keep the good work. Hopefully one I would like to work with you a service call Thank you!!!

[@549BR]

In reference to mobile or manufactured homes, my experience was good with the tenants or owners, and generally not good with the property owners or landlords. They were usually very cheap, and didn't appreciate a high caliber contractor. That unmowed lawn would be the first tip off about the presence of cheap. Hopefully, you will give us a follow up on that call. Good video as usual. 😎

[@HVACGUY]

They didn’t balk on my prices

[@cardsfan-ym1bj]

I usually don't mind the mobile or manufactured homes,most of them in my area are privately owned no management company they just own the lot,but a lot of the big companies won't mess with em so I carved a nice lil niche out for myself.

[@USA-GreedyMenOfNoIntegrity]

I keep telling him that. He must like being abused. I learned that in year one. Now on year 22 I still don’t work for landlords, apartment complexes, commercial businesses, builders or insurance companies. I make a good living, don’t have to wait on my money for weeks or months, rarely have a warranty call after I stopped selling junkitrol aka Goodman, rarely work weekends or after 5 pm. Why, do good work, take care of loyal customers, I’m picky, not anyone’s buddy and I charge above average prices for my area. If you are a low baller, I hope you like working a lot and spending time away from your family.

[@Chris-ru3ri]

I miss those old Rheem units

[@donnyjackson1908]

A nice 4 Ton coil and adding a TXV will likely tune that right in. I believe those Coleman MH Electric furnaces come with a 4T blower drive so should handle 3.5T on high speed.

[@Balticblue93]

That is literally exactly what I said. Throw a 4-ton coil and TEV in and possibly upgrade the blower motor, but a half ton coil is not going to magically fix the system. That is barely worth the work.

[@USA-GreedyMenOfNoIntegrity]

Yeah, the cheap ductwork can’t handle 3.5 ton though. That’s why you put a tall 4 ton coil in there.

[@timesfly1081]

I came here for this comment 😂 At least he got a sale out of it Silver lining?

[@dfwhvac]

Id verify that the evap coil isn’t undersized instead of the condensing unit being oversized. Maybe the duct work and cfm is made for 3 tons. It’s more likely that the evap coil is undersized, but still I’d wanna make sure just in case

[@mikeanonymous669]

Coil was likely replaced and thats why it looks new and had to have the lineset reducer brazed in. The outside unit is the original unit/size that should be mated with a proper size evap coil.

[@robalexander7348]

That was a good find Curtis, it takes a good service man like you to find that unusual problem 👍

[@chrissipple1018]

A different evaporator wil help, but unless that mobile home was built for cooling the duct work is sized for heating too small.

[@adampajcz8719]

No mobile home is designed for cooling. Landlord probably had a 3.5 Ton condenser sitting around and had someone install it when theirs broke down.

[@jameybaker9643]

A 4 ton Evap coil would do a great job!

[@bills6946]

Better dehumidification, for sure

I wonder if the ducting or blower can handle 3.5 tons. Good content as alway Curtis. 👍🏻

[@staind288]

I have a 3 1/2 ton in my double wide. Just put in a little over a year ago. Seems to work fine until Temps get in the 90's. That's just due to poor insulation

[@USA-GreedyMenOfNoIntegrity]

3 1/2 ton is max on AC only, 3 ton for heat pumps. Always upsize my indoor coil 1/2-1 ton bigger than the outdoor unit.

[@clintgray1623]

On double wides need to upgrade the blower motor to 3/4 Hp Complete motor and squirrel cage assembly,

[@johncspine2787]

Amazing..ppl look, but don’t see! In Utah we are having a freak 80+ day right after over a foot of snow literally just melted off..I switched my Mitsubishi mini split (a four head of five available) to cooling, and first was trying to run it like I’m used to down south, with high manual fan settings, and it just..never shuts off even when you reach temperature..so, I do my research, and just put the four heads on auto, with certain rooms at certain temperatures, and..it’s shockingly, shockingly quiet! Both the indoor cassettes, and probably even more shocking is how quiet the outdoor unit is..I’m used to hearing….”BBBLLLAAAAAAAAAAAAAAAHHHH!!!”.. from every outdoor AC I’ve ever heard, and this thing just sort of gently makes a draft of the warmth off the coils..then as I’m standing there, it ramps it down even slower..I’m just amazed by this technology..I’m only using four of the available five heads because I only have four main rooms upstairs, and didn’t see a need to install the fifth one downstairs as I’m by myself, the downstairs seems cool all summer as I’m set into a hill, you walk in my ground front door, then go downstairs and walk out the back of the house, so it stays pretty cool in summer. I think the cassettes are a 12 in the kitchen, 9 in living room, and two 6000 in the bedrooms..the kitchen is west facing so they bumped up the capacity. I’m just beyond thrilled, but, I’ll have to see how it handles the 107 degrees when it comes!

[@RadioReprised]

At 10:50...isn't half of the upflow just porting around the coil ?! Foil ain't sealing a thing!

That was a mess. I hope they change the battery in the chirping smoke detector.

[@analogmoz]

It's not a proper video from Curtis unless there's a barking dog and a failing battery on the smoke detector.

[@user-vy2tx8uc1u]

i think you are on it curtis. Thanks For the video. Im "assuming" this problem is a new one and not been a problem since installation. Makes me think ductwork and blower aspects are Fine. New coil with correct piston should get this one rolling. btw, im assuming we know the previous company replaced the evap with a smaller one. maybe they Found a leak and replaced coil, kinda like they Fixed an issue and caused another one. Thats where my mind is at on this call.

[@georgewelker853]

I would suggest to double clean that indoor coil. Most of the 3.5 ton condensers will do reasonably well with a .5 ton smaller indoor coil

[@gor312]

I'd say the more likely problem is that they have the totally wrong orifice in the system. A 3 ton orifice with a 3.5 ton condenser would give you a very low evaporator pressure and low efficiency. A slightly smaller coil would just mean somewhat lower efficiency, but this wouldn't prevent the system from working.

[@mwdub02]

Usually we go a half ton higher on the Evap. You might want to get a 4T coil if your drive can handle it. Good catch man

[@Balticblue93]

100% agree and exactly what I said. We size up a half-ton on all our systems here in Denver.

[@joshuaseaton4526]

No way, why upsize on a small trailer when the ductwork is high static as it is?? I would do an entire heat loss/gain calc and then replace both based off my numbers. I would gather that place needs probably a 2 or 2.5 ton unit.

[@woodworkking1099]

[@mwdub02]

@@woodworkking1099 I don’t know about you dude but we do VRF systems and that’s top of the line that very few techs can touch. They still oversize their Evap coils. Probably LG and Daikin is drunk too. It really application dependent and I’m not being specific here kid.

Yea that oversizing evaporator coils hardly turns out good for the compressor. I dont get why manufactures go for that.

[@kbmblizz1940]

To help non-trades, superheat too low, suction (return) line ice cold but not enough cooling (air temp drop thru heat exchange) could mean not enough airflow, wrong piston or undersized evaporator. He thinks it is the latter.

Did you a delta split across the evaporator. Hopefully your ductwork can handle 3 1/2 ton Might ask owner to resize to matching 3 to ton

[@stanleyroberts2461]

Is the blower big enough to handle a 3.5 ton unit? Always good to pick up new customers. Keep up the good work

[@timesfly1081]

Honestly I’d try bumping the blower to high speed first before replacing it

[@daleborg9070]

Curtis, I never heard you say what the complaint was as to why you were called.

[@yellowdeer7163]

I once found a 3 ton outside an apartment with a 2 ton evap coil. The manager had a company put in the outside unit??.The line set outside went from 5/8s to 3/4! The resident kept complaining.The apartment had a vaulted ceiling and no insulation whatsoever. This was on a third floor here in Dallas. It was a losing battle with the manager. Talk about kicking a dead horse.

[@Mitch2294]

Proper metering device is first pump it down and check the piston size you could Upsize the piston to feed that coil it’s definitely not going to be maximum efficiency because of the lack of surface area (smaller coil) but it should work most new units have lower btu per ton anyway that unit probably has a 36-38,000 btu compressor even though it’s a 3.5 ton. A quick google research would give you a definitive.while not recommended I think it could be made to work.

[@kens.3729]

What Decade do you think 🤔 that Coil was Last Washed Off ? 1990’s ? Totally Disgusting. 🤪

[@Gutter-Snipe]

first off if your AH can move 3.5 ton of air Coil is not your problem. it does in fact derate the system as a hole some and i am not familiar with what a double wide needs in your area. that aluminum foil trying to block the Air gap in the front of the coil is a potential major problem, add that to the open air intake at the top of the air handler might be the hole ball of wax. some air flow testing might have been a good idea, could also be a TXV with air going around the coil. just my 2 cents performance data of the coil outdoor match up might be just find for sensible and laten.

[@latitude67]

what about the stratus leak finder, i have tested a couple of different leak finders, and nothing beats the stratus in finding leaks, especially when searching for co2 leaks.

[@awshortclips]

I'm no HVAC tech but isn't that unit way too big for that mobile home anyway? I heard when units are oversized they switch on and off (in AC mode) really fast and can make the place humid.

[@mikeanonymous669]

Most mobile homes arent very thermally efficient like a house. They are horrible to cool and just as bad to heat in the bitter cold. Didnt notice if it was a double wide or not.

[@timesfly1081]

Here in Florida, oversized units = MILDEW EVERYWHERE

[@97Napkins]

just my guess right after the evap was clean... Its got to be an undersized coil or wrong piston. could also be wrong blower drive.

[@jeffreyhalet9632]

So the smaller A coil can’t handle the volume coming from the 3 1/2 ton outside unit. Which means the low insulation mobile home needs a higher volume of exchange ? Not an HVAC guy but love watching and learning from you.

[@karellodewijks4971]

👍👍😊😊

[@joshuaseaton4526]

Hey Curtis, even if that unit reduced to 3/4 suction you would be ok. Rheem lineset charts are very forgiving. Very little efficiency drop between the common lineset sizes.

[@clarkbreen4634]

I actually thought being within a half ton was OK guess I was wrong

[@joelmelendez5916]

Tio ..what happen if u change only piston . ??? For a 3 1/2 piston .... ???

[@97Napkins]

better not install a 3 and half ton coil unless its a 4 ton drive or same problem. I bet its 3 tons .. count the vents and the return size. better yet call the manufacture.
