I recently changed my furnace to a heat pump and do not need the exhaust vent in my roof anymore. The company doing the swap does not do any sort of roof repair- they’re just gonna cap it from the inside, but I don’t want water collecting in that 3 inch pipe.

Anyway to plug it from the inside that’s flush(ish) with the top of the vent? The problem is that I have a clay tile roof and to get somebody on there is going to break the tiles. I’m thinking some sort of expanding 3” drain plug or inflatable balloon type device that’s weather resistant.

Or I guess worst case scenario cut it as short as I can against the roof sheathing and cap it there…

I'm looking at a predator york rooftop unit right now and there is no power going from the board to the honeywell economizer module. I have 24 volts every where else but for some reason none to the economizer. If somone knows let me know plz help.

Someone thought it was a good idea to fill the unit with ziplock bags full of sand. Microchannel massacred

Southern California. Commercial Service technician. Over my career I have had shitty paying jobs, with demanding installs, Commission based jobs which was great in the summer and horrible in the shoulder season. I am currently at commercial outfit that pays good for my individual lifestyle. Iv always thought we as skilled technical tradesman should be at higher wages. I am currently at 37$ an hour. I hear 100k from technicians all day on-line, but can’t seem to personally meet anyone who really makes that. Anyone in the socal area have any luck making 100k+ a year? How long did it take? Commercial only

Hey guys, on a mini split, I know the ground/floor unit requires it's own dedicated electrical service. But what about the unit that mounts on the wall? Does it require it's own dedicated circuit as well or is it fed from the ground/floor unit? Thanks.

I have applied to my local union for HVAC, went to my interview and it looks very likely that will be put in their apprenticeship program but my non union company has gave me a raise of about $10, I was making $20 I’m only 20 years old and I’m very unsure of what I should do. The Union has a lot of great benefits that I am aware of but $30 hour right now for my situation is extremely good.

Looking for the most user friendly options. LG wall mounted indoor units if that matters.

Anybody have an ideas what tonnage this Ruud would be?

Im currently working as a dayporter/ maintenance at a commercial building. I have a pretty alright understanding of how most roof top units, vavs and fan power boxes work. Recently been getting more and more intrigued on the hvac and controls side of my job. Is there a solid way to get into the industry without having to go to school?

Hi,

26M. Just got out of PM job and while the salary is very good, I kinda wanna go in HVAC and start my biz in 2-3 years. I don't really like being in an office all day.

I've been offered an apprenticeship as an installer. They do service also if I want to in the future.

Just wondering, how hard is it to build your business in the HVAC industry?

From what I've seen, you need a truck, few tools and that's about it. Probably some sort of warehouse to store units too

Thanks for the advice,

Not gonna be fixing that leak 🤣

I’m looking to get in the field and wondering how likely for someone to make 6 + figures and what you have to do to achieve these numbers

Looking for advice, starting school in may and looking for any pointers or tips to better improve and take full advantage of my schooling.

Hi guys, I was wondering what you guys do to protect your shoulder from wear and tear of lifting ladders up

Two weeks into this new career path and im let go,

Really dont know how to feel bout it

I’m doing some research for the company I work at regarding 2-pipe heat recovery VRF systems. It is my understanding that the two companies I mentioned are the only ones currently in this space.

Is there a difference between the two in how their 2-pipe systems work? To my understanding, both their branch control boxes use phase separation and then direct the liquid or vapour to whichever zone it is needed at. Are there no differences between the two? Thanks for the help!

Recently I started working at a very big residential company that uses Nexstar. Part of it is a mandatory 3 day training about personality types, talking to customers basically to get them to want to buy shit, and they have an exact script that they want you to follow, which for the most part I did already...but some of it is just stupid personally. Am I in for a rude awakening? Does anyone else have experience with Nexstar? I'm not a salesman...I'm trying to be a technician but I feel like I'm going to get shafted while working here because I'm not the guy that scares customers into buying air scrubbers or other bull shit.

I'm debating leaving this trade all together because it seems your options are work for a smaller company that has terrible on call, doesn't compensate you properly and hires degenerates, or you work for a bigger company and you are just expected to be a salesman? Seems like a lose lose situation and I'm frankly just sick of it. Do I get out now or try to stick it out where I'm at.

So the other day I ran into an issue at a customers house. I was there for an A/C check up but I left my locking cap keys at another customers house. I went ahead and went through the motions. Then I went to check the TD and it was only 8 degrees. (I’m in the states.) the lineset was also making an ungodly noise. This check up is complimentary to our contract customers. So I told him we would come back the following day and get it figured out. I suspected a leak maybe. But when I went into the office today for first call some senior techs told me her unit was probably running fine and that it was only because of outside temps. Which was 74 degrees the day of the check up… I’ve had a 20 degree split on many days in other homes when the outside temps were lower though… I was thinking that it could be we were moving to much air across the coil, a leak, amp draws. I’m not sure. But I don’t agree with the other techs that say NOTHING is wrong. Something is amiss here.

Question: so how much should TD vary compared to a full blown summer day? Can it really get as low as 8 degrees and still be functioning properly?

Charge me!

So I had an interesting thing happen on a PM today and I’d like some actual insight as to why/what caused it to happen because it has me stumped

Walked up to a 410A package unit that was 2 circuits. First circuit was low on charge. No biggie. Checked airflow and stuff before adding refrigerant. I put maybe 2-3 short squirts of refrigerant in and my head pressure skyrockets and trips the compressor almost immediately. Low side didn’t really move that much. I ended up having to take the refrigerant I added plus some more out before it settled down to normal levels for the ODA. The condenser was spotless clean, fans working, no filter drier restrictions and the TXV appeared to be working correctly. Any ideas fellas?
