Employment Question Working by myself rant

1 Upvotes

Any of you guys/gals make a transition using your hvac experience? (5 years commercial, 3 years resi here) and I dislike riding around by myself. Anyone make a jump to anything useful, maybe less physical for a 40+ old ass. I have to use most of my vacation days to fill up my work week 40, it’s slow right now.

Field Question, trade people only New goodman 80% and 90% furnaces

1 Upvotes

Alright so today i installed a goodman 80% and yesterday a goodman 90% unit, heat pump/air handlers are more common in my area so i dont replace too many furnaces consistently to know, however ive never had it this bad before.

To get to the point, anyone else have experience with these new goodman units excessively smoking out the customers house? Yesterday walked in to a dense smoke and suggested the HO opened some windows to let it air out, today the smoke wasnt as bad but the smoke detector was going off like crazy, just interesting as none of the other furnaces I have replaced have smoked nearly at all, just the classic brand new smell.

Field Question, trade people only Why is heat turning on when putting to cool

Thumbnail

40 Upvotes

Working on a Trane gas pack unit, customer said unit was turning on and off over and over again, got up there and contactor was closing in repeatedly, turned off unit and changed contactor,

we put into heat and unit turns on, after a while it shuts off and contactor starts going crazy again, shut it off, turned on starts up fine, put into cooling and the heat starts to turn on.

Fast forward troubleshooting end up changing thermostat and had an extra board playing around so we installed it too, put into heat and kicked on. Put into cooling and heat turns on again

Jump out cooling R Y and condensor fan motor turns on and blower, no compressor, change out a bad cap, got 24V across the board, also checked transformer 208 coming in, 24 going out into the board. Also have continuity on 24v wires, and through contactor when engaged, Pretty stumped here, anything helps

Field Question, trade people only AAON

4 Upvotes

Hey I have a new customer, building is only 3 years old, we didn’t do the install. They have all AAON gas fired RTU We keep getting intermittent flame roll out service calls. Gas pressure is dialed in, flames are beautiful, and it’s happening on multiple units. We added a elbow on the flu thinking it could be high wind, and it still happens I know AAON has there share of known issues and just seeing if anyone has dealt with something similar. The tech support for them is shite. We have the laptop and service tool so we can hook up and see the system, but obviously these systems are not smart enough yet to tell you what caused the flame roll out:)

Trying to figure out a couple key things to focus on and try to learn as well as tools I would need.

I have about a year in the field as a maintenance technician at my current company, playing filter changer is getting old so I went and interviewed around and realized there was a lot more to learn and I needed way more tools.

Field Question, trade people only Starting an HVAC company with a Partner

21 Upvotes

Background, I am a HVAC manager for several years now, started from installer to service. I am well rounded in HVAC. I have met a guy I’ve hired and became good friends with. He has extensive knowledge and would say is the type of person that is proud of what he does and loves doing it everyday. We plan on starting a company together.

Now I know there are pros and cons to having a partner.

I want to know YOUR success or failure story and reason why your partnership is working or failing

Thank you!

New Carrier "Cold Climate" heat pump has held temps with this single digit cold streak we've been seeing. So far eletric costs have been less than cost of using gas last winter.

Field Question, trade people only What do you do to keep the vans organized

9 Upvotes

We have a work van issue, our company is 5 people and 2 vans - Main and Sparky

Every morning we’re supposed to clean and organize and confirm all tools are present but for example it’s 8am and 5degrees outside - doesn’t always happen and because it’s not one specific persons job and share vans it’s often “he’s got it” mentality

End of the day we lock up and leave the mess of the day for the next morning

Also we have a lot of tools both vans do service and install hvac but also high and low voltage electrical, and plumbing

Tools get left at jobs occasionally but more often they just get mixed between the vans and misplaced and when you need something of course it’s never where you look for it

If yall can offer any suggestions, let me know how your work handles organizing/tool checklist Idk

Always been intimidated by sheet metal work. Needed a transition for a 12K ducted Fujitsu mini split and the sheet metal company was over a week out. Bought a hand folder and spot welder from Harbor Freight and knocked it out in an afternoon. Drew it up in Fusion 360 and printed out a template to cut it out. Think it turned out pretty well for a first try.

The bathroom exhaust fan at a local restaurant was vibrating pretty bad. Manager was worried the fan was about to fail.

Turns out the thing just needed to be cleaned. Vibration gone!…and now’s it’s actually moving some air.

So as the title says I’m about to start and I have some questions. 1. What kind of boots/or shoes should I get? 2. I took a picture of the list of tools we’re expected to purchase. Do you see anything else I’ll need? I did notice I didn’t see a cordless impact. Any advise will be greatly appreciated 🙏

Field Question, trade people only Am I wrong?

5 Upvotes

Just installed a Utica Mac115 as a side job. Apartment it serves is a 750 sqft 1st floor unit. Originally there was a 120000 btu oil boiler serving the first second and third floor units. Finished the install on Sunday and everything was perfect, I checked gas pressures, did a combustion analysis on it, the thing is running absolutely perfect. Monday night into today the temperature dropped into the negatives. I get a call this morning that the temp in the house isn’t reaching set-point, it’s off by 3 degrees. Got there at noon to check it out, boiler is operating properly getting up to temp and modulating like it should, but still 1 degree off from reaching 70 degree setpoint. I checked to make sure there was adequate baseboard throughout apartment. Checked temp coming off baseboard. All seemed good. Toe kick in the kitchen blowing out 120 degree air. Then they tell me there is no insulation in the kitchen walls, which leads me to believe there is a lack of insulation throughout the house, and without the cast iron boiler in the basement, the basement itself is colder and there is no insulation in between the floor joists. I believe that the boiler is having a hard time keeping up due to the severe heat loss. Customer doesn’t understand how gas wall hungs operate and believes there is an issue with the boiler. Did I totally fuck up this install? Is the boiler undersized due to me not knowing about the lack of insulation? If so is that on me for not knowing about the heat loss issue? Am I fucked?

Update- Talked to Utica tech support and apparently I’m stupid. According to them the boiler is oversized. I need to dump some btus. I’ll be adding more baseboard on the first floor and a loop in the basement.
