Hopefully in the mean time our little portable AC holds up, because it's Finals week and we need the school network. Wish you could be out here doing the install, or even just a review of the air system. It's ancient>.

Sounds like the place is one of those holes in the wall community colleges I've gone to, had a couple of semesters where they didn't give a rats ass about network performance enough to where some classes had to leave early on some days.

[@EnderMalcolm]

@@MrKillswitch88 It's actually awesome to be there, just having some financial trouble. We had two buildings, one owned and one rented. The rental agency was price gouging the college, so we moved entirely to the other building. The issue was that, with all the construction work and with covid, building maintenance lacked a bit, and the AC failed before it could be repaired. The network performance is usually great, they just need to keep the room cool, and that's hard to do while there's an AC down.

I did not realise that there are people who think NTE means "fix it for this much". No guys, its the opposite, the customer preemptively gives you permission to spend up to that amount to fix the problem. The NTE is the customer's way of saying: "If you can fix it for less than X, just do it immediately please. If it costs more, we want to know before you continue." They don't want to you to waste time checking with them over an amount that they are going to agree to anyway.

[@HectorFabela-k6u]

@@vinny142 A lot of my jobs the customer asks me for an NTE before they send me. Which is my rough estimate based on experience. Then of course, if I need more time or materials than that, I call them up. I have never had a decline for an NTE increase.

[@martinkisiel]

Was probably a headache for you, but fun video for us to watch! Love the content.

[@EyeMWing]

As a customer, NTE just means 'if it's going to be more than $x, there's some additional thought that needs to go into it' For example, we had our hot water heater at the shop stop working. NTE we gave the plumber on initial diagnosis was $300. Essentially, 'emergency callout and swap any sensors or filters or whatever'. Two hours later, we get the prognosis: Everything about it is dead. Technically fixable, but it'll cost ya. We were already planning an expansion that would require more hot water, which is why we set the NTE so low. So we worked with the plumber on estimating the upgrade for that expansion, worked out that shutting down for the week, comping our customers with prebooked appointments and doing that work would be cheaper in the long run than throwing parts and labor at the old system we were going to replace anyway, and shutting down for a week in an orderly fashion. If our HVAC were to stop working, we'd have a very low NTE because we'd be waving the estimate for repair at the landlord about it to see if we can get them to pitch in to replace the paleolithic garbage with modern units that don't cost a thousand bucks a month to run 6 tons. Like, any action beyond 'replaced bubblegum part and hosed the wildfire ash off' is farther than we really want to go.

Labeling those things correctly is such a big deal! I'm telling contractors installing them at my work usually that if they don't do it so that even my trainees would be able to make sense of what is where, then I will make sure to give them a call as soon as something is wrong in 5 years and if they cannot identify what is where within 5 minutes of them being there, I will get 25% of my money back from everything they have just done. I put this into our contracts to make it legally binding and usually they are doing a good job of labeling them anyways, but damn it is frustrating when they haven't done that correctly when installing it!

I can appreciate the sarcastic comment you're making in the title about clients avoiding any sort of regular maintenance, as well as always opting for the cheapest option when making the recommendation of replacing a part preemptively so it is not breaking by surprise when the weather gets hotter and the ACs have to work extra-hard. But the thing is, we have a maintenance contract with a guy coming over every now and then, cleaning everything, checking temperatures and if there are any problems in the making, and also following the recommendations of replacing stuff, and the damn ACs still break by surprise, especially when they are needed. Maybe ACs are just shit by default.

I think it's great that guys who make parole can find a job changing filters. However, these clients don't realize what they lose by not paying an HVAC contractor to do that work.

Recently, at one site, the filter rack rods and media did not reach all the way across the evap. About 10 inches of evap was left exposed. I called them and talked to their service manager.
