Question

What is the red switch plate at the top of my basement stairs for?

Vo-tech student, electrical, Passaic County class of '27. This is about my grandparents' house in Wayne, which I've been looking at much more carefully since I started the program. At the top of the basement stairs there's a switch with a red plate that says something like "burner emergency." My grandfather says it's for the oil burner. They converted to gas a few years ago and the boiler is new. Does that switch still do anything now? Is it supposed to stay with a gas boiler, and if so, why is it at the top of the stairs and not next to the boiler? I'm only asking out of curiosity, I'm not planning to touch it.

Before you go out on your own: what nobody tells you about year one

I get asked about this every week, so here's my list from 25 years, the last 14 running my own company: - Get your license first. As I understand NJ's rules, registering as a home improvement contractor is not the same as holding a trade license, and it doesn't let you do licensed work. Check with Consumer Affairs. - Insurance will cost more than you think, and you need it before your first job, not after. - Price for callbacks. If you don't, every callback comes out of your pocket. - Your first truck doesn't need to be new. It needs to start every morning in January. - Keep your books from day one, or pay someone who will. - Most new owners undercharge for the first two years. I did. Ask questions below, I'll answer what I can.

I'm not hiring HVAC helpers without a 608 anymore. Fair or not?

Hiring two helpers for the heating season. This year I'm making the 608 a requirement to interview, not something we'll get to after you start. My reasons: - It's cheap and you can study for it on your own time - It shows me you'll finish something without being chased - I can send you to the supply house or put you on a recovery job on day one - The last three helpers I hired who were "planning to take it" never did I can see the other side: someone who's never been around equipment doesn't know what half the test is talking about. Tell me if I'm wrong.

From the hiring side: why a paper trail matters more than you think

Here's what I look for when I hire, and it's not what most young guys expect. When someone tells me they have three years of experience and all of it was cash, I usually believe them. But I can't verify it, and on our public jobs everybody goes on certified payroll from day one, so I'm starting them at zero on paper whether I like it or not. The applicants who stand out walk in with something I can check: pay stubs or W-2s, a 608 card, a letter from a past employer, a log of jobs with dates and who they worked under. It doesn't have to be fancy. It has to exist. If you're getting paid cash right now, start that log tonight. Nobody's coming to build it for you later.

Where the money from a $189 service call actually goes

Every year a new tech sees an invoice and asks why he makes $22 an hour when we charged $189 for forty minutes. Fair question. Here's roughly how I explain it at my shop. Numbers differ everywhere; this is the shape, not a formula. - The tech's wage, plus payroll taxes and workers' comp on top of it - The truck: payment, fuel, insurance, repairs, the stock on the shelves - The office: the person who answered the phone and scheduled you - Drive time between calls that the customer never sees on the bill - Callbacks, which we fix for free - Slow weeks in October when the phones are quiet and everyone still gets paid After all that, a healthy shop keeps a margin, and plenty of shops don't. I'd rather you understand this before you go out on your own and price yourself out of business.

EPA 608: what my students get wrong every year

Every fall somebody in my class assumes the 608 is a formality. Here's what actually trips people up, in order. First, they skip the Core section because it "isn't technical." Core is where people fail. It's rules, dates, recovery requirements, and it's all memorization. Second, they cram the night before. You need to know the rules, not just recognize answers. Third, they don't ask how their specific test is given. The format depends on which type and who's proctoring it, so ask the testing organization before you show up. Go for Universal if you can. Ask me how I know you'll want it later.

Honestly thinking about adding an HVACR license to my electrical shop

Honestly didn't think I'd be asking this after 22 years. Half my calls down here involve heat pumps now. A lot of the raised houses went all-electric in the Sandy rebuilds, and I've been doing the circuits and handing the customer off to an HVAC guy I've known forever. He's retiring in the spring. So I'm weighing getting the HVACR license myself versus hiring someone who has it. Anyone here hold both an EC and an HVACR? Could I even meet the experience requirement at this point, or am I starting from zero? Kash, I'm looking at you.

Don't cut a line set on demo until someone certified has recovered it

Saw this twice this summer on fit-outs, so I'm posting it for the electrical apprentices. You're demoing a space, there's an old split system or a rooftop unit coming out, and someone hands a first-year a pair of cutters and points at the copper. Don't. Unless someone with a 608 has recovered the refrigerant and told you it's done, that line set may still be charged. Cutting it vents refrigerant, which as I understand it is illegal, and at close range it can freeze-burn your hands and face. Ask the GC or the HVAC sub, "has this been recovered?" and get a name. It's the same as LOTO: you don't assume it's dead because somebody said it probably is. Glasses and gloves either way. Stay safe.

First week of the fall semester: 22 new faces, three have held a torch

Every September I swear I'll stop being surprised, and every September I'm surprised. New class started this week. Twenty-two of them. Three have held a torch, and one of those set his sleeve on fire in the first hour. Nobody hurt, everybody learned something. First thing I teach, before anything technical: where the extinguisher is and how to use it. Second: how to sweep a floor properly. They laugh at that one. They stop laughing when they find out how much of the job it is. For anyone who trains helpers: what's the first thing you make a new person learn? Ask me how I know it matters.

Cape Cods: ductless heads upstairs or a ducted unit in the kneewall?

Settle a fight at my shop... we're doing a lot of Capes in Gloucester and Camden County this summer, upstairs is 85 by 3pm and there's no ductwork up there. Half our guys sell a head in every bedroom. The other half want a small ducted air handler in the kneewall or the attic with short runs to each room. So this one time in AC I put three heads in a Cape and the customer called the next summer saying the kid's room was freezing and clammy and the other two were fine lol. Oversized head in a tiny room. What do you guys do and how do you decide? Not looking for a brand war.

Side jobs, from the owner's side: what happens when yours calls my office

Happened again this month, so I'll write it down. A homeowner called us for a no-cool on a mini-split installed last year. Not our install. A helper from another shop put it in on weekends, cash. No permit, no proper evacuation, flare connections leaking. The homeowner wanted to know who to call about it, and the answer was nobody. What it looks like from my side: - The homeowner pays twice, once to him and once to us - If your own boss gets that call, you're probably done there - Handling refrigerant without your 608 is its own problem, and having the card doesn't make an unpermitted install legal - You have no insurance, so whatever goes wrong is on you I'm not telling anyone what to do on their own time. I'm telling you what it costs when it goes wrong.

Question

where can a condensate pump actually drain in a finished basement

ok so long story, we're doing a furnace and coil swap in a split-level in clifton and the basement is getting finished. right now the condensate pump just dumps into the laundry sink with the tube clipped on the edge. homeowner wants it "hidden," so the contractor finishing the basement asked if we can run it into the washer standpipe or tie it into the sump pit. my lead said "depends" (of course) and that it's the inspector's call. what are the normal options and which ones get people in trouble? also does the pump need anything wired to it besides the plug

Heat wave week: 14 no-cool calls in two days and what I keep telling new techs

So this one time in AC... ok it's this week, not one time lol. 14 no-cool calls Monday and Tuesday between Cherry Hill and Washington Township. Half were dirty filters and clogged condensate lines, a couple capacitors, one frozen coil the homeowner "fixed" by turning the thermostat down to 60. What I keep telling my new guys on ride-alongs... check airflow before you even think about the charge. Check the condensate before you blame the unit. Drink water in the truck between every call, not when you're already dizzy. And if the attic is an oven, do the attic part first thing in the morning and come down for air often. Nobody gets a medal for passing out over an air handler. What are you guys seeing this week?

Where do people in the city actually sit for the 608?

Two years in, non-union electrical shop in the Bronx. We've started doing a lot of PTAC and through-wall unit replacements in apartment buildings, and my boss wants two of us to have the 608 by the end of the year. Searching online gets me a hundred sites and I can't tell which ones are legit. Some say online with a webcam, some say you have to go in person. Is there a supply house or a school in the city people use? Or is the online one fine? Appreciate it.

Hiring two first-year apprentices this fall. Ask me what I look for.

I run a mechanical company in Burlington County: HVAC and plumbing, mostly schools and warehouses, a lot of it prevailing-wage public work. I hire apprentices every year and this fall I need two. I'm not posting a job here, and I won't take applications through this site. But I get asked the same questions every time I interview, so ask them here and I'll answer honestly. Fair warning: our jobs are on public schools, so there's certified payroll, background checks, and early starts. That isn't for everyone, and that's fine.

From the inspection side: whose license belongs on a heat pump swap

I get some version of this question every week this time of year, so I'll put it in one place. Not legal advice; your local construction office has the final word. As I understand the current rules, a condenser or heat pump replacement in NJ usually touches more than one subcode. The mechanical work goes on a permit from a contractor holding the HVACR license. The new disconnect, the whip and any circuit changes are electrical work, which means an Electrical Contractor pulls that permit or the work is done under one. Some companies have both licenses in-house. Plenty don't, and that's where I see trouble: the HVAC crew runs a new circuit because the panel was right there, and nobody pulled the electrical. The HVACR license is also newer than a lot of people assume. If I remember right it became required around 2014, so you'll still meet techs who talk like it doesn't exist. If you're a helper and you don't know whose license a job is under, it's a fair thing to ask. And find out which edition of the code the permit falls under; it changes what I look for.

Target superheat needs indoor wet bulb. Students, buy the probe.

Every summer a few of my former students come back from their first jobs saying they "checked the superheat" on a piston system and it was fine. Then I ask what their target was and they look at me. First, superheat by itself is just a number. On a fixed orifice system you compare it to a target, and the target comes from the manufacturer's chart or a target superheat chart, using indoor wet bulb and outdoor dry bulb. Second, wet bulb, not dry bulb. Wet bulb tells you how much moisture the coil is dealing with, and that moves the target a lot. A sticky July afternoon in Paterson and a dry day in September want different numbers. Third, measure the return air at the unit, not in the hallway. Buy a decent wet bulb probe before you buy the fancy gauges. Ask me how I know which one matters more.
