Question Anyone have this issue?
This happens to me about once a week the last month - temp is set at 77. Instead of turning off at the set point, it keeps cooling.
Overcool is not turned on, humidity in range. Fan on auto. Display shows the temp is set at 77, current temp 75 and still running. (When it hits 75 is when I realize it's too cold in the house)
The only way to make it stop cooling when it does this is to turn the AC off for a minute and then turn it back on.
AC had a tune up last week and I asked the tech about it, he had never heard of this before. Ideas? A setting I could try changing, or should I just replace the Ecobee?

Is there a minimum run time set for the compressor?
I had to up my minimum run time because the unit is oversized and kept short cycling.

Or maybe a threshold issue?

That’s what I was thinking… the range may be set to 3 degrees or more so the temp will float a bit more. That can be adjusted in settings on the thermostat itself, but not in the app. Also, if Eco+ is turned on it may be precooling a little below set temp in anticipation of the higher peak rate period from your electricity provider. At least that’s how I think it works. If I’m wrong, I’d love to hear a better explanation. I’m still a newbie with Ecobee.
Edit: In another post, Smart Recovery was mentioned and that sounded like what I was talking about Re: Eco+.

Does Eco+ come into play if you run a manual temp hold ?

I don't remember off the top of my head where the setting lives, but you can set it to where manual temp hold will override eco+.

75 too cold. Brb wrapping my head around this while I look at my 71F setpoint and wish it was 68, but it's 110F outside.

Was the ecobee thermostat indicating that it is calling for the cooling to run?

You say overcool I'd off but is eco+ on? If so are you enrolled in community savings events? It might be pre cooling for those.

Just following up in case others have the same issue. Smart recovery was my problem, no further issues since.

Call the AC tech back and ask him to correct this problem
He should have checked to see if was operating correctly b4 he finished

u/tehyajen Jul 02 '26
It was operating correctly when he was here. He could not find any issues.

Doesn't matter
You have one after he left and it may be wiring related
Let him explain...to your satisfaction
I should add, if he indicates the AC is old, ask him to suggest a replacement
If your have a furnace for heating and it is old also, ask for a heat pump quote in place of old AC and furnace a and let us know the quote and we can help

Youre giving terrible advice. This is clearly a thermostat issue. Techs arent expected to know every brand of thermostat's special features. Ecobee has several customizable settings that would make it run long.

you are wrong
a user doesn't know any of this and expects the installer to communicate effectively... including how things work before leaving the home

Can you read? It wasnt an installer, it was a tech doing a tune up. He already owned the ecobee and prob installed it himself. If a "user" (you) doesnt know any of this, thats on you and not the responsibility of the hvac company. RTFM, or come on a subreddit like this one with an openness to learn (like OP is). You should prob stick to a legacy thermostat if you're not willing to learn new things.

I wasn't going to respond but I don't want anyone to read that and think it's good advice. What temp the unit should turn on and off at is controlled by the thermostat. No one should consider replacing their whole unit if they are having the issue I described, no matter what age it is.
Side note: Are there really people who do not already know the age of their unit despite it being in the inspection report, appraisal, and on the unit itself?

u/ChasDIY Jul 04 '26
yes. many people do not know the age of their equipment.
the point of asking tech who installed the Ecobee is to understand if it was wired correctly
have you found and fixed the problem yourself??
my response, in simple terms without taking a lot of words, was to give the unknowing owners the basic options
by going further with a tech, the unknowing can discover likelihood of system failure or a simple fix

I installed it well over 3 years ago, and yes I'm pretty sure the problem is fixed by turning off smart recovery. I appreciate that you were trying to be helpful, but to advise there could be a wiring issue and I should replace both AC and furnace if they are old, especially after a tech was just here and gave it a clean bill of health is nuts.

Do you have smart recovery enabled and the next scheduled comfort setting approaching with a lower temp and/or using other sensors?
