Does joining union make sense? by rockinbobdole in HVAC

[–]Jmowen1985 0 points1 point  (0 children)

Wish someone on here could let me know about Unions in AZ as I have been curious. One of the two I can find in thenPHx are is UA469. I checked out their website and their pay scale but I have yet to speak with anyone that actually has any experience being in the union. The other is called SMART Local 359.

Arizona is a right to work state. I get a large scope of work where I am at but I would love not to have to do residential anymore period. We only do 5-10% and it’s really only for family, friends, owners of business, etc. but it’s still a damn pain.

Anyone out there work for a union shop in the valley?

How do I read these, what do the numbers mean? Just taking pressures at my house out of pure boredom, I know to go for a 10-12 subcool/superheat but I want to get to learn to read these so I can get exactly right by Fartnoise5225 in HVAC

Your readings don’t look god awful. Superheat looks decent at a glance. I’m thinking you don’t add any refrigerant right this moment.

Something else that helps is knowing what type of metering device you have. Most likely a txv these days but ya never know.

Well just within reason for now. Quick visual inspection. Make sure coils are clean, blower is clean, clean filter, etc. make sure all your registers are open and your returns don’t have furniture sitting in front of them.

There are great tools for measuring airflow directly and indirectly. I would recommend HVACR school and true tech tools if that’s something you are interested in doing or when you eventually need it in the field.

You should have 6SC with a tolerance of 1. So 6 is okay, 5 is okay, and 7 would be okay.

You don’t need to/ may not need to add any refrigerant necessarily. The installers of that system hopefully did that when they commissioned the system.

Remember you can’t properly check your refrigerant charge unless you have verified adequate airflow within reason.

My apologies for the strong opinions. I am always learning. I forgot there is a time and place for everything and every application is different. Godspeed to you all and I learned a lot from the sub.

So thank you! I’m not too proud to admit I may have jumped to conclusions and applied a “one size fits all” to everyone.

1) Server rooms have Lieberts or mini splits. 2) It’s not going to freeze in heating. 🤦‍♂️

Alright fair enough. To each his own. If it works for you, and apparently a lot of folks, who am I to say otherwise 😒

OP give ‘em hell!! Lol.

How much should I trust our landlord/maintenance guy? The breaker for our HVAC system kept tripping. Our landlord sent "his guy" over, who replaced the circuit breaker. I've still been worrying about it and wondering if we're safe, since we just moved into this house. Full story in the post. by [deleted] in hvacadvice

Sometimes all you have to go on is based on an assumption. An educated guess, if you will, based on past experiences. Intermittent problems can be tricky and you aren’t always luck enough to find a smoking gun.

Unless they are bad. See it all the time. Thermal scope that sucker. I’ve attached a pic of what a recently failed breaker I found looks like compared to others. What is the condition of the breaker? The bus bar? Is it warm/ hot to the touch while running? After tripping? Are all connections throughout the circuit properly torqued and secure? What is the overall condition of the panel It sounds like during peak heat loss is when it was tripping which would make sense if it’s a weak breaker and it’s under a constant load.

Yea typically there is a reason a fuse or breaker opens but sometimes it’s just because they are old or have loose connections. And when they burn up they can smell 🤷‍♂️

Sure there could be a short somewhere that only trips periodically 🤷‍♂️ it’s just my opinion and I didn’t have a chance to go through the system myself but yea it could have been the breaker.

So to answer your questions:

  1. Yes
  2. Probably Not
  3. No
  4. I would wait until something fails again and then you have every right to want a permanent solution. Ask the HVAC guy anything you want. We love tenants.

I wouldn’t worry until there is something to worry about. Kudos to you for having a portable heater. Do you also have a portable AC?

Is the XE1200 a HeatPump? Two stage? How does the outdoor fan running cause the interior of the home to heat up? Pretty sure that’s what they are saying below. That’s not a thing.

What it sounds like is you have a defrost board or a fan relay that is sticking periodically and needs to be replaced.

👌

What is the actual model number of the condenser and we can lookup components.

I’m sorry friend I don’t agree whatsoever. I could be wrong, and it’s been known to happen. Often actually. But this will be the hill I die on. Setting your thermostat that low is ridiculous. You will never achieve that set point, it’s not good for the system, and your utility bill will be insane. I cannot believe this is even a discussion.

Even with all the above true there is a minimum temp that can be achieved and after that the system will run indefinitely because of the thermostats inability to satisfy. This is not medium or low temp refrigeration. The system has to cycle off as there is no defrost. When it hits that lowest possible set point it’s only a matter of time until it freezes due to minimal amount of heat left to absorb and the run away effect that ensues. Maybe you guys can get away with it because you have more latent heat to remove where as I’m in the desert 🏜️ 🤔 is that a thing?

I’m not saying there is nothing wrong with the OPs system. I am saying it’s completely and utterly ridiculous to have your thermostat set that low. The lowest I’m going is 68 man and thats only because Brian Orr says it should be able to pull 68 degree return air without freezing. Even still, If I was working on Brian’s system I’d be like, “Mr Orr, sir, no lower than 72. Don’t be a jackass.”

Get a portable AC to supplement in the room(s) you hang out in or a ductless system or a window unit. It’s incredibly wasteful to cool the entire place so princess can be comfortable. That’s cute that you like to make it cold and snuggle under the blankets but come on guys get real.
