Home is not cooling

Llewis — Fri, 01 Jul 2022 23:34:47 GMT

I am having cooling issues and the thermostat saying 2+ hours to cool the home. My ac unit is running but my home is not cooling. I have also changed the filters. Please help troubleshoot this issue it is 90+ degrees out.

sometimes the ac unit is working so hard because of heat you may want to check out side to see if there is frost around line, the fins all around are clean and clear of leaves or other air blocking material. Also sometimes the unit in the house above the furnace that connects to ducts can freeze up because it gets dirty over several years. if you see any water by floor where unit is then that would be the case. some places to start

I am also having this problem. I already checked all the things listed above and they are fine. We have hired 3 ac repairmen and none of them could find a problem with the ac units. Any other suggestions to do with the nest thermostats? Thanks for the help!

Me too same issue! Had my NEST 3rd gen thermostat for over 3 years. Earlier this summer I enabled Learn Mode - inside temp was between 72 to as high as 78 degrees. With the externally high Arizona temperature I disabled Learn Mode, but the unit acted as if Learn was still on.

I could not bring the inside temperature down to 72. The display showed 2+ hours to cool. My AC unit is two years old, with no issues. I tried factory reset the NEST, even turned off all energy saving features, schedule off, etc. display showed 2+ hours to cool.

Called tech support twice to report this issue. Had me reset device, same issue. One of the tech's mentioned this is a known problem and a possible software update maybe needed in the future. Since tech support could not explain or resolve this problem I had no choice but to remove my NEST unit and install a Honeywell non-programmable thermostat. Set thermostat to 72 degree and house is now maintained the set temp. Maybe NEST will address this issue and provide it customers a solution. Disappointed to say the least. 😞

I find that those times like 2 hrs to cool or heat can be way off at times

Hello DanMag,

Thanks for reaching out to the Google Nest Community Forum. I'd love to know more about this.

Could you share a photo of your thermostat's wiring with us? Are you getting any message codes or wiring reports? Also, please gather the power readouts from its settings under the technical info.

I'll look forward to your response.

Thanks.

Mark

I am about to do my brothers. He got the same thermostat as me. wonder if we will have any issues when doing his.

I did have to redo all my google home stuff when I got a new modem. When I did that somehow it must have gotten an update or something because this time i actually was able to say I had the 24v common wire. When I do my brothers I will start with saying I have the 5 wires Y/C/W/G/R and no OB* . The problem I had early on apparently is no longer an issue, at least not with mine. I just said I didn't have a C wire and it worked before when it use to give a fail code or something.
