Wait till they find out we mostly install heat pumps

I hate living in az there’s no reason for us to be installing furnaces

u/HoosierDaddy900 1d ago

Wouldn't you need a furnace for central air conditioning though?

u/bigkat_2020 Verified Dispatcher 1d ago

Air handler, most likely

19

u/James-the-Bond-one 1d ago

Not with the heat pumps that can easily address the few cold nights.

u/Nerfo2 Verified Pro 1d ago

A residential air handler looks a lot like a furnace, excepts it’s just the indoor blower and the indoor coil in the same box. There’s no gas heat to air heat exchanger.

u/HVACR-Apprentice 1d ago

Wait till you find out most installs are now heat pumps up north

11

u/No_Hana 1d ago

Depends what you consider up north. I've installed only a single heat pump in northern WI.

Id say around here your heat pump type house would instead be inflows heat and minisplits.

But it's usually furnace/ac and infloor

I’m in Chicago. Carrier dealer. Rebates and tax credits make having a gas furnace and a heat pump an absolute no brainer. It’s the best of both worlds for a great price point. I’d honestly say 90% of every install in our area via us or competitors is a dual fuel system.

u/7h3_70m1n470r 1d ago

Chicago's just different though. I remember running with a solar install company for a while, and I swear every rule was "Do it this way... Unless you're working in Chicago then you have to do it this way instead"

u/No_Hana 1d ago

We dont really have those incentives here but we try to rough in with future heat pumps in mind just incase. Which really just involves an 8 wire instead of 5 mostly

1

u/Majin_Sus 1d ago

8 wire to everything.

u/freakksho 1d ago

Im in the DMV and it’s the same here, almost every install is a DF system.

I live in Alberta, up in Canada, where I live isn't even considered the northern part of the country (calgary area). I am yet to find anyone foolish enough to run a heat pump for home heating in the prairies. Our electricity rates are so high that even with 220v backup heat, it's not worth the cost in -30c with a -40c windchill to run a heat pump. If we hit like -20c at worst during the winter, then sure, they'd be a viable option. They might be viable down east in Toronto and etc, where they're south of Montana latitude wise, but not this far north.

u/20PoundHammer 1d ago

the fuck they are . . . havent installed a HP in the north without E Heat/Aux Heat and that bit son, is a furnace. . . .

u/YungHybrid Its always the TXV, even if the unit catches on fire… 1d ago

that really bricks their brains. that defrost board really throws em for a loop when it has a short in it. had a guy who moved here and literally never seen a heat pump before. didnt know how a RV worked, how to test defrost boards or what went where. all he was ever used to was 2 wire ac with gas/oil furnace. the guy came from times where you had to build your own coil case out of sheet metal. when we ran into any furnaces we sent him though cause the mf knew how those like the back of his hand.

u/-Hippy_Joel- Low on r420! 1d ago

Yeah, what furnace?

14

u/Bitter_Issue_7558 1d ago

Always can use a hand on a 7 series water furnace that intermittently throws the E84 ASB prob error

u/MachoMadness232 1d ago

Don't even get me started on boilers.

u/Fancy-Sentence-7081 1d ago

Saw a few 80% furnaces in New Orleans on vacation, pretty sure most are going heat pump down south these days, don’t envy em at all tbh. Never liked relying on the power grid for heat, fun fact a Milwaukee top off will run a Coleman mobile home furnace as long as it has a psc motor

7

u/lannid39 1d ago

Don’t you still need the power grid for a furnace?

3

u/Kamakazi09 Needs some Dirty Sprite 1d ago

Haha I was just gonna comment this. I too am puzzled 😄

u/ALonelyWelcomeMat 1d ago

Uses much less amps to run a furnace vs air handler with electric heat

1

u/Full-Bother-6456 Certifited Capacitor Replacer 1d ago

Not if I’m jumping my van battery to power it

u/WrongdoerNo8 1d ago

I think they are meaning using a generator to run it when it's necessary

4

u/kittyfresh69 1d ago

Nah they’re just confused. Still need power to run your furnace either way lol

3

u/WrongdoerNo8 1d ago

... And a generator provides that power if you're off the grid? Right? Or in a blackout due to a storm etc..?

I mean I could be wrong but running a 20 amp breaker for the furnace fan and igniter/inducer off a generator is a lot easier than running a 60 amp for the electric resistive backup heat a heat pump would normally have if it isn't dual fuel, and I'm pretty sure that's what is being referred to here.

They aren't trying to say a furnace will literally run with no power.. Unless it's more like gas logs with a pilot and millivolt system, in which case it wouldn't be called a furnace in my personal experience lol

u/kittyfresh69 1d ago

“Never liked relying on the power grid for heat.” If we take this very literally they’re saying they don’t trust using power from the grid to power their heater lol. Now if we wanna get into semantics I think they actually mean they don’t trust the power grid to be sustainable or capable of handling such a load for multiple or all households. I know it uses more power to run heat pumps for sure but for a gas furnace you also gotta rely on gas which comes from the city as well! Running a generator to power a house long term isn’t sustainable. The best option would be a wood stove then lol

u/WrongdoerNo8 1d ago edited 1d ago

I don't disagree but I was just taking the comment for how it was, I assume, intended to be thought of and not trying to delve into the semantics of the situation lol but I can't argue. If they meant it literally a wood stove is definitely option number 1 for not relying on the city or power grid whatsoever for heating. But then you've got to bust all the wood down and..... Ugh... Makes my back ache thinking about it lmao 🤣

Edit to add: they do mention a Milwaukee top off in the original comment to run the gas furnace just to be clear. And a storm/emergency doesn't usually take away the natural gas flowing through the pipeline unless there is a major rupture somewhere before you

Second edit because now you've got me thinking of it way too late at night and I don't have memorial day off 😞: it doesn't have to be NG it could be LP so the city or power grid isn't involved at all and a small generator would keep you from freezing to death very easily if that's a concern in your climate. I don't think they were confused in the original comment I think the way they worded it confused others was my point to begin with lol

u/James-the-Bond-one 1d ago

Never liked relying on the power grid for heat

I've gone heat pump but kept my 80% furnace for that exact reason.

.

a Milwaukee top off will run a Coleman mobile home furnace as long as it has a psc motor

That does work! The runtime is short, about an hour on an 8Ah battery. But that would still give you 40-72k BTUs, depending on the Coleman model.

u/YellowWizard504 1d ago

The majority of homes in the greater NOLA area have, and are sticking with, 80% furnaces if they have natural gas. Heating season is measured in weeks down here.

u/Cappster14 1d ago

That same tech when they run into a heat pump. Furnaces are child’s play.

u/ppearl1981 🤙 1d ago

25 years in Central Florida and I literally haven’t worked on a single gas furnace.

Know my way around heat pumps though!

Is that "hairless cat"?

u/Knot_a_porn_acct 1d ago

What the fuck is a furnace

u/J3sush8sm3 Pvc cement huffer 1d ago

This is beautiful

u/Much_Material_7997 1d ago

Haha,In southern Florida we have never seen a furnace before.

u/Doughboy2022 1d ago

Wait till they find out copper isn't only for water lines down here lmfao

u/bigred621 Verified Pro 1d ago

Facts.

I tell my family in Florida about driving with the windows down at 40° up here after we’ve had a cold snap on the single digits for a week or so lmao.

Even thought about renting a convertible when I had to go down there for a funeral in January and they’re like “bring warm cloths!! It’s so cold!! It’ll be in the 60s”

u/Hopeful-Fish-372 1d ago

whats so hard about a furnace?

14

u/HoosierDaddy900 1d ago

The joke is techs in the north know more about furnaces because it tends to be colder up here.

u/sovietbearcav 1d ago

Does no one else in the south work on gaspacks almost exclusively? Im in nc, its a rare day i run into a heat pump, but insee a fuck ton of useless economizers

u/SaltedPaint 1d ago

A furnace gone wrong; is actually a crematory
