14:38 there is a GREAT example of this in the failure of the Sampoong department store disaster in Korea. If you have never heard of it I suggest at least reading the wiki, but the short of it is, the did a bunch of stuff to the building it wasn't designed for, and the straw that broke the camel's back was moving the air conditioning units around on the roof, caused the whole building to collapse, full of shoppers.

@GGigabiteM

The A/C units on the Sampoong roof caused a punching shear failure of support columns. The building was already grossly overloaded because of illegal additional floors added to the building over the original plans, and the relocation/undersizing of existing support columns to allow for more open space inside the building. The building was already in imminent danger of collapse because of the overloaded columns, and there were several columns that had the floor separating away from them before the A/C units were moved. The building would have collapsed on its own eventually, but the vibration from the A/C units rapidly accelerated it.

It won't be a problem. Ive set up a ton of these already and changed a few. 5 mins and the motor , wheel, turbine is out. Easiest motor to take out and clean.

Impressive job! So nice to see someone take pride in the simplest but profound details of your job. Good job with drain line and gas line.

I don't think that they "don't anticipate it." They simply don't care about the environment it runs in, because they met some DOE standard for lower wattage. Also, many building design "pros" are not cable of designing good ductwork. They too only care about the cost.

ive changed on out its actually pretty straight forward and quick. The hard part was just getting the motor. The one I found dead was back in early Jan, Sigler said they couldnt get it until end of February

We have switched thousands of our units to Merv 13 filter and knowone took the time to see if any of the units were designed to use them! All the motors are running less amps day of change,afyer a month the motors are down 1.5 to 1.9 amps. So we are saving energy,while doing much less work.Not to mention alot of the filters are bow shaped after only a week!

Looks like the motor actually in heat exchanger compartment with air blowing down across it?

Comment towards the “eco-blue” blower assembly, likely unrelated to any issues you’ll run into with them but curious if you’ve encountered the same thing as myself. I had issues with a very similar packaged unit I installed that would intermittently trip the fan limit located beside the blower during the heating season (-40C -20C winters from where I’m located). Talked with tech support and was informed the blower motor itself in my particular unit was wound for a 50hz power supply where we have 60hz. Perhaps this may relate to why your unit wouldn’t produce the expected CFM based off the ESP/CFM chart.

Unless I'm looking at it wrong, that blue fan looks like a conventional bladed type. I wonder why they thought that was more efficient? The engineers aren't going to be the ones cleaning it, which is probably why it's hard to clean.

1” of static is up there but it is what it is. if the costumer don’t wanna change ductwork, put it in the report you said to change it, and let it ride. Running only in Cooling with high static isn’t good on the blower motor, and compressor if superheat is Low. But high static on heat pumps in heat mode may be more detrimental to the lifespan of the compressor because of head pressure, what do you think? 6 one way half dozen the other? I’d say a majority of ductwork is sized wrong around pnw WA too. Great video

Nice job ! From my experience. The blower assembly just need to get a new shaft, wheel and a bit of screw to old that motor bracket… And for the cracks that u see under it. When u retrofit that blower thing and dissambly it. U take 4 metal holed can-trust and u made a stronger floor for the blower and it will not shake again. Yes there is a short to ground somewhere but its maybe so easy to find . Especially on the 24v side. And for the honeyweel jade economizer control.

It really depends on the scale of the project. Some (larger) mechanical contractors have separate divisions of sheet metal, pipe fitters, refrigeration, start up, and even TAB (test and balance). The projects I work on always go through TAB where they test, adjust, record and balance airflow(and water if applicable) to the mechanical schedule laid out by the MEOR (mechanical engineer of record). It can be a painful step of a project, but really shows that all air handling equipment, duct work, pumps, piping, etc. was installed correctly and is performing as expected.
