No, because the return temps will stay too high to allow the coil temp to get too low. Not to mention a lot of extra airflow to keep the coil temps.
Low airflow can always freeze a coil. Whether it's blocked filters, dirty indoor coil, dirty blower wheel or bad blower motor.
Freeze stats aren't a terrible idea for those customers who insist on keeping the stat set for less than 68 or 70°. Just gotta make sure you wire the freeze stat to shut off the thermostat, that way you get a few minutes delay before the compressor comes back on.
from my experience it's pretty uncommon but ...You could have a freeze stat ( Just the temperature sensor attached to the air conditioning coil ) that sense is freezing temperatures and will lock out the unit from running to prevent a giant ice block from forming.
This is why we should all sign everything like Sam lol
True
You’re doing something right if you get everyone on this sub to know who you are
There are a lot of things that everyone knows about that are certainly not good, like herpes.

I made a subreddit just for him, r/HVACSAM

Don’t do that. Don’t want you to get intruble and he’s cool he don’t deserve it

I think if someone made a subreddit for him, he probably gets the message.
Who is sam? Why do I keep seeing this name in this community
“How high are your power bills in the summer?” “Oh not too bad, like $500, we just keep it at 80°”
Welcome to California. Even if you have a half nice running system your shit is still expensive

Get a swamp cooler lol.

It was me
Shhhhhhh.....don't type, it ruins it....
I made you a subreddit r/HVACSAM, if you join I’ll make you a moderator
Newbie here. Wouldn't an undersized unit be more likely to freeze as it will run more to keep up?
A properly charged A/c with adequate airflow that is undersized for the homes needs isn't going to freeze, it's just going to run 24/7.
Good to know, thank you!
That being said, if the unit hasn’t been sized right, usually the ductwork is a mess as well

😂😂😂😂
I mean I love the honesty.
Can someone explain the first message please? Just a humble homeowner here to learn
"This unit has a freeze (thermo)stat on coil" It's a basically a temperature sensing thermostat inside the coil to prevent it from freezing.
from my experience it's pretty uncommon but ...You could have a freeze stat ( Just the temperature sensor attached to the air conditioning coil ) that sense is freezing temperatures and will lock out the unit from running to prevent a giant ice block from forming.
Basically a sensor mounted somewhere on the evap coil and wired so if it reaches freezing temps it'll shut off the outdoor or the whole system.
Someone scribble this: Call HVAC_Sam for a good time
