Your "favorite" (pet peeve) type of hack

[Fridge_expert]

No pictures for this one unfortunately, but a sharing experience for all of us!

I'm a big fan of ductless splits (Mitsubishi is my favorite!) and I want to install a system in my dream home one day...

but..

The sad thing about these is when I see a nice one installed and the lineset is all coiled up and left on the roof or the ground to rot in the elements, like, how hard is it to cut it back and reflare??

Or at least coil it up in the attic or something...

I guess I can't really judge most of our fellow tradesmen in respect to their quality of work. I look at their results and see an opportunity to share some wisdom. If they just don't care, the system will usually weed them out unless they get their attitude adjusted. That said, techs who leave trash (spare parts, soda bottles, butts, fast food bags) in their work area should be chastised for their inconsiderate action. There is no excuse for trashing another's property. That would be my rant on the question at hand.

The total charge is calculated for a 25' line set. I myself just can't do that.

If i weren't mistaken i think you can use a short line set on a Mitsubishi unit with the factory charge, the condenser is large enough to handle the extra refrigerant that would otherwise be in the line set.

There are only a few things i like more than a clean/organized tidy work area/van. I've seen guys with a van like a tornado hit yet they know where every screw is located, i myself couldn't pull that off

I agree.

I know for when I went to training there is a minimum length for a line set I think it was 15 feet

you are correct, 15' minimum

My pet peeve is door switches taped closed.

[mattt787]

I think that's what they said if you have less it could have problems and to coil the line set flat to not trap oil

Yep. I'd say I see that on about 30-40% of the units I service.

Dead comps left on the roof. The idiots had to bring the new one up, but cannot carry the old down, and turn in for recycle. Older restaurants are the worse, stuff hiding under and behind ductwork!

[jtrammel]

Armaflex ripped on line set, suction and liquid line grommets on ah/coil left out, gas line ran at an angle (swing joint) just because someone is too lazy to make a couple more threads and put in an elbow, tracpipe, Romex in lt flex from disconnect to condenser, flex improperly installed, leaving boots unwrapped because of laziness, mastic on insulation but not on the duct joints, and no service disconnect in line sight of a piece of equipment just to name a few.

Control wires spliced in stupid places, like at the end of a whip tucked under a package unit, inside the hood or curb, between return and supply ducts, even inside disconnects. Always just put together with wire nuts, too much insulation removed so bare wires are exposed.

Ditto! Have a 12 story beach front condo where whole condensers are left on roof to finish rusting away, even their cardboard boxes are left up there.

Old refrigerant jugs left on roofs, mechanical rooms and roof hatch access closets.


The future isn't what it use to be.

Piles of old air filters in attics and crawls... At least one can drag it out and put it in the HO's trash can.

I'm going to go with tobacco spit. Where I used to work, I'd say 40% of the work force chewed. In all of their laziness, they wouldn't walk to the floor drain to spit, but rather just spit on the block wall.

Now a close second is sunflower seeds. I would eat them, but kept a cup that I'd spit them into and throw away. Most did not, and just spit them everywhere.
