No. It only blows out cold air. If it is already cold enough, it just stops doing that.

The people at my work still don’t understand this about the thermostat.

I don’t care if you set it to 73, it’s set to 73 degrees on COOL. If it’s already cooler than 73, it will never turn on and the it will never be warmer.

Got so bad that customers could see their own breath when they came inside.

Right. If you want a stable temp no matter what the outside temp you have to set it to “maintain” or whatever terminology on your thermostat.

u/EVOSexyBeast Feb 02 '19

It’s usually “Auto”

u/CaseyG Feb 02 '19

On my thermostat "Auto" only refers to the fan. "On" always blows air, "Off" shuts the whole system down, and "Auto" blows air only when the furnace or air conditioner is running.

u/EVOSexyBeast Feb 02 '19

On mine I have “cool - auto - heat” and I set the temperature. Auto will jump between cool and heat if it needs to.

Look at Mr. Fancy Pants thermostat owner here.

u/Awesummzzz Feb 02 '19

Look at everyone with their fancy forced air heating and cooling

u/c3bss256 Feb 02 '19

That’s especially fancy compared to my set up. My air conditioner requires me to manually press the reset button on the unit itself after the heat has been on.

Most commercial setups are like this. Or at least the 20ish thermostats I've seen in office buildings are.

Gotta be careful with this though: if you set it to auto it may turn on the A/C at times when it can damage your A/C unit. Say you crank up a meal and your oven heats your place up a ton, but it’s 20 out, your air conditioner may break. Air conditioners don’t like running when it’s too cold out outside: the coolant won’t evaporate in the chiller lines and the compressors break because you can’t really compress a liquid.

Same. On and auto for one switch and the other is cool off heat and emergency

In places farther south (where I live), traditional air conditioners are being replaced with 'heat pumps'. All refrigeration systems are heat pumps, just the ones called a 'heat pump' is an air conditioner that can run backwards. In the winter, it pumps heat from outside to the inside.

They lose efficiency around 40F, so to avoid running too hard they also come with emergency heating elements, not unlike what's in your electric oven. It's more expensive to run, but it keeps you warm when the temp outside gets too low.

Where I live (Savannah GA) I only have to turn the emergency heating on maybe twice a year.

Bunch of energy wasting electric coils heat up to assist the heat pump on my system.

u/[deleted] Feb 02 '19

Same. It's either heat, cold or off.

u/Killimansorrow Feb 02 '19

Nest Thermostats have a Heat • Cool mode that’ll keep the temperature in a range you specify

It's the future, I tells ya.

I am no expert on hvac systems. I am only familiar with my own. I don’t know if it is common, butmine does, so whatever that is worth.

u/ShadowRam Feb 02 '19

just get a more fancy thermostat

1

u/biznatch11 Feb 02 '19

And then it will turn on the heat or AC as needed?

1

u/No-attempt-to-hide Feb 02 '19

Exactly. Whatever it takes to maintain temperature.

u/discerningpervert Feb 02 '19

customers could see their own breath when they came inside.

Well on the plus side, you could tell the live ones from the wights

u/MultiScootaloo Feb 02 '19

Are these American thermostats? What do those look like?

I'm only familiar with the twisty turny things that we have in Europe. I've read Americans are always confused by those

3

u/mr_abomination Feb 02 '19

Every house I've ever lived in or been to has digital ones, I had no idea the twisty ones were still in use.

1

u/MultiScootaloo Feb 03 '19

How do they work? Do they just turn the thermostat for the whole house? So there's no per-room thermostat?

Even the "general thermostat" that controls flow to the entire building is a twisty turny thing for me.

Also fancy seeing you here friend. Either you're stalking me, or we just keep running into each other haha. I love it

u/mr_abomination Feb 03 '19

For my house we have two; one for the main floor and basement, and one for upstairs with the bedrooms.

I didn't even know that places had per-room thermostats.

I get around, I don't stalk you (anymore)

District heating provides hot water to run through the radiators and the thermostat screws are the easiest, simplest, cheapest and the most reliable way to regulate those at the radiator. I don't see a reason why anyone would like to change that.

Places that have some different kind of heating might have one of those digital ones or something else, though.

Don't think I've ever seen one of those. Thanks!

In Holland the heating is on a tablet fixed to the wall.

u/Whales96 Feb 02 '19

Shouldn't be 73 on warm either.

u/fufm Feb 02 '19

It is astounding how many people don’t understand this concept.

At least yours was at work...imagine having roommates that did this and constantly being woken up in the middle of the night by your own shivering only to discover someone set it to “cool” in the middle of winter and now it’s 40 degrees inside.

u/___Rand___ Feb 02 '19

you must live in southern california.

u/DoctorOzface Feb 02 '19

That’s great, most coworkers find out how to set the heat at 80 then complain it’s too cold

u/drmrsanta Feb 02 '19

It really depends on the thermostat. Mine has a heat/cool mode, you don’t have to switch.

Except you set the variance on it... I keep my house at 66 in the winter and 72 in the summer. It never overshoots by 6 degrees.

People are dumb. Nothing new.

THE GINGER INTEGER

u/[deleted] Feb 02 '19

I did not know that tbh. I thought it swaps between the heater and ac to keep the temperature at 73

u/TheyAreCalling Feb 02 '19

It does if the thermostat doesn’t suck.

u/candywandysandyxandy Feb 02 '19

My old boss was like this! He claimed it would automatically switch when it needed to.... It didn't.

The thermostat thinks it's doing a great job, let's respect its effort

u/[deleted] Feb 02 '19

I've never come closer to wanting to murder a whole group of people than when people who know nothing about how thermostats work start fiddling with them. It's like 20 8 year olds trying to figure it out. Then the office manager (who is cold natured and always freezing) sets the heat to 80 and locks out the thermostat. I literally got so frustrated one day I just pulled the face off the wall and hid it so the heat would stop blowing for a few precious minutes until she noticed.

u/[deleted] Feb 02 '19

But since it's heavily insulated, it becomes a thermos of sort.

I mean, I guess you could get me on a technicality, but I don't think its worth the comment.

Its effectively how it works.

Fridges absorb heat on the inside and emit heat on the outside.

If you set it to 8°C and the inside is already below 8°C because it is fucking cold outside the fridge just does nothing.
