Hey guys long time no see! I haven’t been online in a bit but have been watching an online discussion about if a flow check is needed in this application.

I always installed them in the thought...

Your not kidding. We have been getting so many water tanks, boilers etc with manufacturer defects, and thats if we get lucky and they aren’t smashed by the warehouse guys. It used to be rare now it...

🤑 annoying for sure. I have a love hate relationship with inverters. The ones we had the most issues with “Life’s good” at least had the handy little service tool you could plug in and get...

Thanks for the great advice, is one of those other part numbers and actual service tool? I’d think with the volume we are doing mitsu would either give us one or it would be a good investment. We...

My supplier is going to let me borrow a MA controller and I’m going to ohm out the thermistor. With correct charge and fan set for high the unit has been heating perfect all week thank for even...

My DSG confirmed that even with the older unit it should still lockout. So I suppose now it’s also a matter of finding out why the heat pump isn’t.

Thanks for adding some insight. I believe we took this into account when ordering. It’s only a small condo. This was a while back but I believe that for being one of the deterring factors for going...

This unit being one of the first iterations of the 1/1 ducted with standard chassis, what I was told they do not lock out heat pump unless state of error. I think maybe the reason I haven’t had a...

Hey all,

I installed a mitsu ducted combo a few years ago, Suz / Svz kp30 Na2. Out of the hundreds I’ve installed this one seems to always be the thorn in my heel. Oh EH-10 electric heat kit as...

Trust the science!! Haha I think the aprilaire accordion style filters do a great job, the uv lights I’m not sure of. I’d imagine out there in the golden state the air quality would rule out such...

Yeah. I also let my helper know where it is just in case. That’s not how I want to go haha. It’s basically a shot of pure adrenaline, enough to make all your vessels constrict and open your airways. ...

I went to an allergist after I had the bad reaction and told him I’d like one for peace of mind, at that point they almost have no choice but to write the script. Else next time you get stung and...

This also helped me a lot when I was attempting to learn AC.


LOW CHARGE = High superheat. Low suction pressure, indoor TD, subcooling, head pressure & compressor current draw.

OVER CHARGE =...

I was never allergic to bees until last year and I’m 35, I have a weird reaction called “serum sickness” though not the usual swelling. I get stung now and 10-11 days later I break out I’m full body...

What’s the old saying, as long as you wait until after lunch your not an alcoholic or was it breakfast? I think it was breakfast. Carry on.

I’ve never not did an attic job because it was too hot. We just get it done, that’s my summer weight loss program. I don’t understand how guys could not take summer attic jobs, if the person doesn’t...

The key for installations is to get up there early and acclimate as the attic heats up, typically if I’m doing a change out I’ll get the return hooked up and wire it in with the fan jumped out and...

Nice install OP. You clearly take pride in your work, not sure the fuss over the 1” filter, if they are changed regularly it doesn’t matter which we all know.

Seems you have been bamboozled.

Looks pretty good, I’d try not to go past 90 with the tubing though, that suction lines looks about as close as you can get to being kinked. If you brought your suction line straight down you...

It’s not the best but definitley works. Helps to heat the tubing a little. I have got myself out of a few jams with it. Easier than the old pound in ones.

Yep that’s the one, I’ll never go back to a regular one after using this one.

Getting the nitro reg that clicks into the different settings for psi test , braze etc. was a game changer for me makes it so easy to flow while brazing. I used SB8 for a year or two but lately it...

Yikes! Are those shark bite for refrigeration lines? Now that is scary.

Everyone I’ve seen in the field has been when repairing the leaking joint it’s on. I think they are garbage.

The new bubble wrap isn’t the easiest or fastest thing to apply “correctly” I think it gives a nicer product than the old FSK wrap though. I like that with a good pair of scissors you can make a half...

Y’all don’t use bubble wrap?

One of my favorite part of being in the field is all the interesting people you get to meet, I’ve come across all sorts of grows in basements, from reptiles to reefer. I feel like the weed isn’t as...

Any friend of Paul Stamets is surely bound to be an interesting character, look that guy up!

When I’m assigned to this type of install I always will send an email out to the sales team to explain all of the reasons it’s a bad idea or won’t work, that way 6 months later when it’s FUBAR with...

Field controls makes a lot to do this, satisfies code in a lot of places that want in for every cfm going out.

We usually tie in the range hood to the same setup.

Blown in insulation after us, plywood works good, we nail off a 2x4 parallel at the base so it’s strong. I usually run some webbing over the top back to the board as well and cut arcs in them to...

Only Union guys that I know that don’t have work are the ones that don’t hustle and can’t self manage or think. The guys I know that were good and hard workers before going into the union seem like...

The bubble we use is rated R-8 with the air strips. Works great and not as much complaining by the apprentices.

Yikes, that looks awful bad. Clearly no care for craftsmanship, new construction is tough to make money but they could have at least supported the drain and zip ties the low voltage.

I do 95% of my attic jobs in round pipe. Works great, easy to seal, insulate, can be installed by one person easily 5’ at a time. Fittings are easily bought at the supply house, take offs 90s etc and...

I’ve had a bunch of Veto bags, the ones I’ve come to stick with are the tech LC and the OT-XL for tinning tools. I also just picked this little guy up and I’m liking it.

I’ve got too many red tools, in 12v the bandsaw and the pipe cutter are my favorite though.

So again, you would have cut off the zip ties that were installed by the factory knowing it would cause a problem in twenty years?
