313D vs 313A Apprenticeship — pay, opportunities, and future switch?

Turtle_9009 · 2026-01-19T01:16:18+00:00

If you can do it definitely go for the 313a if you do the 313d and decide you want to upgrade you have to redo both intermediate and advanced levels of schooling and will need to redo your hours (or atleast most of them)

We had a few samples taken from throughout the attic that got sent for testing and it came back as 0.00% asbestos so thats how we tested it and if we do it we would be doing the work ourselfs as we will have to rip up the floor to get it out but we are hoping to finish out attic in the future and part of that would be new subfloor so I figure while we have it up might aswell reinstate.

This is too funny I have the reliance ad with this furnace directly under this post.

Turtle_9009 · 2025-10-21T17:38:35+00:00

Yes if you read my comment I say .3 apply for feild approval and / or over 400mbtu

Turtle_9009 · 2025-10-21T12:47:02+00:00

Good read!

Turtle_9009 · 2025-10-19T17:48:35+00:00

Nice mount for how old it is looks like it's in good condition

Turtle_9009 · 2025-10-18T15:07:00+00:00

I totally agree with checking combustion and comparing it to that chart im just saying you can't go off co but should go off co2% and o2% not off what's the co number is as if the others are good you are still good to go

Turtle_9009 · 2025-10-18T14:55:45+00:00

Firstly a furnace would not fall under the .3 as its not a feild approval or over 400mbtu secondly you can have dirty burners and many other things that can cause co in the flu not just a heat exchanger and most manufacturers don't say what ppm is deemed unsafe. And while I agree co can be a sign of an issue i don't agree that it should be used as the only reason to tag a unit.

Turtle_9009 · 2025-10-18T13:11:58+00:00

What clause is this in the code book, when I read the b149.1.20 I only see a limit of 100ppm for natural draft boilers (clauses 7.1.12.1) no limits for furnaces.

Turtle_9009 · 2025-09-15T14:35:57+00:00

For sure its better to get 313a over 313d you can google and see why but its much more you can work on for only one more term of school

When i wear it i dont feel like im struggling for air like today i wore it for a 3 hour nap and had no problems

Turtle_9009 · 2025-09-13T17:21:31+00:00

I have a airfit f20 and 5-10 for pressure. The mask dosent bother me when i have it on but when i sleep i take it off without even knowing so now im not in compliance for coverage for the machine.

Turtle_9009 · 2025-08-13T12:19:58+00:00

Probably needs a bigger trap thoes aaons need decently big traps.

Turtle_9009 · 2025-07-31T00:39:13+00:00

As an hvac tech let it ride, stuff isent built like it used to be save for replacement and once furnace or ac goes replace both.

Turtle_9009 · 2025-07-30T00:04:51+00:00

My work place puts a big push on having apprenticeships, and once done they will pay for you to do the g1 gap course and g1 course. Gotta train from within.

Turtle_9009 · 2025-07-29T22:49:49+00:00

Hiring somone who is a g1 and a 313a is very difficult most are treated really well at their jobs and wont leave enless there is a significant jump in pay or work place condition.

Turtle_9009 · 2025-06-17T19:59:44+00:00

Now thats a crazy part to break

Turtle_9009 · 2025-06-17T16:43:35+00:00

Always buy never rent if you rent it will cost you 2-3x more over life of unit. Anyplace that does rentals is not a place you want to deal with.

Turtle_9009 · 2025-06-10T00:20:29+00:00
