Hey guys this might seem dumb but I'm trying to figure out what the ideal controls setup for refrigeration systems utilizing cooling towers are that people use across the board. More specifically...

nice, I see what mean there about what is essentially an inverted trap that would hold air, may have to look into redoing that, I wonder though if the head created from that drop would eliminate it?

Hey guys so this summer has been a bit crazy and I've been put on some water projects rather than my usual realm of refrigeration which has been a great learning experience but I have some questions....

I been bouncing back and forth between Ariat and Justin lace ups over the last few years with little complaints. I usually run with the safety toes and electrical hazard rating stuff which is...

So I'm no mini split guy so forgive me if I missed something basic here but just curious what you guys think. New customer called up, has a Durastar 3 head mini split Model#DRA3U28M1A installed in...

lol how do you add refrigerant without measuring refrigerant? what tech support guy just says, "ya add refrigerant if its not blowing cold air?"

sorry bro but you have the same music interests as my old high school girlfriend, your soul needs to be cleansed.

holly batman, you could argue a monitor or guage is a control. a guage takes an input pressure read and thus give an output read which controls my decision to overcharge your AC.

well i would argue a monitor isnt a control it is a monitor kinda like a gauge or digital display. a control like say a temp control (tstat) takes in input(the temp) and gives an output(open/close...

probably not what you wanna hear but I'd stay OEM if possible if not though I kinda like using the KE2 controls. they are usually the temp control and defrost in 1 unit.

these places are in the more normal areas of California where housing is extremely affordable and most voters are conservative

lol where is this my guy cuz as far as i know the valley and sierras...

they're covering their ass. Fieldpiece lately hasn't been winning points for reliability. Personally I've bought 2 wireless temp clamps and a micron gauge in the last year that have had problems and...

this is what I meant by a sales guys mental image, where guys run a vehicle thinking this is how the customer thinks and will thus generate more leads of a particular type. Only thing that bothers me...

just my 2 cents but I would think you'd want to drive whatever suits the task their performing. I worked for a contractor once where all the office/sales guys drove 1/2ton trucks but didn't use the...

on the topic of whiskey I gotta recommend a jamison + rootbeer crème soda on the rocks.

i would go oem especially if they're tandem. those tandem compressors usually have a hard piped link for the oil and a manifold for the refrigiant lines and it adds alot of labor if you have to...

I know its not always possible but if the wind is coming from say the west I'll put it up on the east side of the building where there is less wind. I've only ever had a ladder fall due to my own...

there is no magic formula to marketing. If you wanna obtain commercial customers you need to meet commercial building/business owners and sell yourself to them just as you would a residential...

Curious if anyone on here has looked into what it takes actually build coils. Have always been intrigued with the idea of building my own ac condenser and with the supply shortages/ lack of quality...

pellet grills are the modern way to go. pretty straight forward to use, its honestly like cooking in the oven but with wood pellets. I'd recommend a Pit Boss, pretty good quality I'd argue better...

would bet $100 its not 410a in the system. if the condenser says r22 its not designed for 410a pressures, u can also check the compressor tag if it says mineral oil its definitely r22, if its poe...

just based on these readings I'd guess refrigerant restriction, but like the other guys said there's possibly more to it. sounds like your hinting that maybe the ducts are screwed up.

ya its seems like its becoming more and more common. We have several customers that run portable chillers on manufacturing lines that every couple years they replace with used ones which is ok i...

not sure on the evaps but that condenser has definitely been outside for the for a few years, there's the usual half of the panel screws are missing, rusting/corrosion on the filter shell bolts and...

yup, and it came with 2 matching evaporators.

best part was about an hour into me being here the install contractor shows up and I asked him if he wanted me to pull off so he can fix his system, and he said no but he'll come comeback another day...

lmao ya....

that compressor plate is the one in the "new" unit

tag as in data plate or tag as in invoice?

So my company was gonna quote a new cold storage system for a local cheese plant but they found someone cheaper. of course we get called to come out and fix a warm box the following week. the...

around here you probably got 50/50 chance with a tagged truck of it either being a legit knowledgeable tech or a complete rookie working for someone. The untagged guys its like 50/50 you either get...

So I'm a HVACR service tech who does a little bit of everything and lately I've started reading the manual J and Manual T books. At this point in my career I don't actually design or sell systems but...

Ya I'm aware of the possible problems with a 407c conversion and the customer was made aware before the job began but comparing the price of 200lbs of r22 vs 407c in todays world for a system that...

So did a conversion of an old r22 system over to 407c and when performing the oil change the drain filter came out totally plugged, oil was black lookin like old motor oil. So in this instance when...

well here in california we usually don't have the battle with humidity. All these systems really need to do is pull down the sensible heat so alot of guys can get away with just using the 400sqft...

nice! I was at a dairy one day that always had a couple of grouchy dogs roaming around. went to go get a couple tools out of truck and when i shut my door it startled one and he made a quick chomp at...

I don't believe you can change stats as its a communicating system. the boards in the condenser, furnace and tstat are all sending feedback to each other and if anyone of those is missing it won't...

what exactly is the point of this. Are you trying to be alerted of a specific component failure or just being alerted of a system failure sooner. I think everyone gets all gung hoe on controls but...

I'm not looking for a safe heaven I wanna fix the problem. I wanna how we get the industry to work together and try and actually do better work rather than "make more money." It almost seems like...

ya I made that maintenance dude sign a tag and they're getting a bill for the time I left house till I got home, all overtime of course as it is a saturday.

So as a technician I had a rather frustrating experience today in which I got called out to look at an AC at a Union industrial plant. upon showing up to the job I started my diagnosis which was a...

got it. However just opened the zip real quick and noticed the exe said Quick patch. Is this the actual tool or just just a patch for the tool?

much appreciated sir.

lol well thanks for a response. ya did some digging and the cable and an old xp laptop I can get, its the gx software thats being a bit of an issue. from what I'm gathering this software is gonna...

So an old customer recently purchased a multistory building which has a single 50ton ac system for the building controlled by a Metasys/ johnson controls EMS system. TBH my backround is more...

I see what ur trying to say here and I believe you're talking about "quoting a repair" which in a way I will do for instance I get a call, service call is charged by the hour, then I diagnose say a...

I mean if all you do is residential ac or only chilers and boilers I could see flat rate working, maybe. For a Company like where I'm at where you go to residential, then a restaurant, then a dairy...
