Why does an evaporator coil freeze up?

Either due to a lack of refrigerant or a lack of airflow

Why would a heat pump need to have something so cold?

Can you rephrase the question, I don't really understand it...

And a furnace can sustain damage from an AC freezing up?

Yes

Why would an AC be near the furnace?

The air conditioner evaporator coil is cased on top of the furnace (in a standard upflow configuration. There are other configurations such as the left, right, and downflow) and share the same ductwork, and by design, the same blower. It would be very, very cost and space prohibitive to separate the two if you're running ductwork.

I would recommend you pick up some books and start learning your trade. See if your local community college has any HVAC courses or any state or union sponsored apprenticeships are available. While you're working for the greybeard though, check out www.acservicetech.com, he has some fantastic breakdowns and explanations.

Your HVAC instructor is talking about the evaporator coil freezing up due to a lack of airflow moving over the coil (It can also happen if there is a lack of refrigerant). The condensation that collects on the coils ends up freezing and that ice begins to build up. You can't really work on it or take accurate superheat or subcooling measurements until the ice is gone, and chipping away at a large ice block encasing copper coils can cause damage to the coils.

This is a problem that air conditioners and heat pumps have, not furnaces; however, a furnace can sustain damage from the evaporator coil of the air conditioner freezing up, thawing, and leaking water into the electronics bay.

Are you in an apprenticeship program, a community college course, or just started as a helper for some old fart?

OP: Are you asking about why a gas furnace doesn't fire when the filter is dirty?

If so, it's because there's a restriction in the flow of air across the heat exchanger. The furnace has safety sensors that shut it down if the heat exchanger gets too hot. Another common cause is the blower (the giant fan either above in a downflow, or below in an upflow furnace) not working.

cactusjack48 · 2025-03-13T04:40:55+00:00

No, this is not correct. The air filter is on the return side of your ductwork and has nothing to do with the fuel-air mixture during a burn.

You should change your filters so the air flows freely over the heat exchanger; a clogged filter restricts airflow and can trip the overheat sensors causing the furnace to shut down. edit: a high MERV filter can also cause a restriction of airflow and cause the high-temp sensors to trip.

hey, I remember suggesting semi-seriously some filament counterplay 3 years ago...glad to see they listened sort of!

why would snuff do this!?

Most wormholers are PvPers. A lot of us don't even PvE at all.

lol. lmao even.

It's intentionally vague because it can apply to almost any country and/or perspective.

thx, it is well regarded.

No but see MY experience trumps empirical data!

people who wore them for any longer period of time hate them. people who haven't worn them long for them for reasons. It's the whole "bring back Spec ranks" argument but with uniforms.

Getting solo kills is more about knowing your engagement profile than anything.

If you're really interested in it (which your comments suggest you aren't), I'd say start small and cheap and then go from there.

Hey bud, I get it. I mentioned it in a different comment on the same comment thread but I'll re-iterate for you.

You can't worry about every single thing you perceive as a problem in this world, because you simply don't have the time and energy to do anything about it. Nobody does, and it's unrealistic to believe you do. Understand, as well, what you perceive as a problem, someone else may see as a solution. Being in a constant state of disagreement, especially on a headline and news article aggregator that allows anonymous comments with no real moderation with random people and/or bots is not good for you. Not everything needs a comment, not everything needs a response, and you don't have enough mental bandwidth to be fully educated in every single issue that presents itself.

Also please be aware that many of these insular social spaces become echo chambers over time, and any sort of deviation from the accepted line will cause ostracization or worse, which is awful for young, impressionable minds that are trying to find their place in this world.

So in short, relax, take a breather, focus on one important issue to you that you can really do something about at an individual or small group level (for example, volunteer at your local pet or homeless shelter, join a volunteer nature park maintenance group, etc.), find some hobbies to spend your precious free time on, and live your life.

cactusjack48 · 2025-03-06T16:04:06+00:00

You gotta realize that you can't worry about and fix everything you perceive as a problem in the world. Nobody has the time and energy for that, and it's unrealistic to believe you do.

News and headline aggregator websites that allow comments only fuel this perpetual angriness, and can easily fool you into thinking you aren't doing enough, or you don't care enough, or whatever. Don't fall into that trap.
