My Honeywell thermostat isnt keeping my house cool even though the temp is set to 69. Currently 90 degrees in here

I set the thermostat to 68, and instead of blowing out cold air, it blows out heat and I don't know why

Its probably not the thermostat. The air conditioner may be stuck on heating mode. If its a reverse cycle, the reversing valve may be jammed so even when the thermostat is calling for cold air, it stays on heat. If the machine is on heating mode, it should be blowing cold air out of the outdoor unit of the air con. If its on cooling mode, the outdoor should be blowing hot air.

Just moved into an apartment with a Honeywell RTH111B. When I got here it was 75, five hours later it's still 75 even though I set it for 68. Any hope I can get to a comfortable (for me) temp?


Temp depends upon ur action of opening and closing door frequently and also depends on your system whether filters are cleaned or not. Plz check.

I have a honeywell ct3200 with a trane xl 80 furnace. it will cycle on to the right temp, go off and cycle the furnace back on 30 seconds later. Is that normal? It is 32 degrees outside, set at 68


Hi, check page 22 in your manual, it says "Adjust the screws on the back of the thermostat as instructed on page 7." Your furnace is a 80% efficiency but is also a high efficiency 2 stage heating system so try adjusting screws A and B both ways and see which gives you the correct cycling.

Honeywell RTH230B a/c problem


if you set the thermostat on 70 and your house won't get ant cooler than 72, there is a problem with your system,not your stat. I'm thinking you are low on refrigerant if it is somewhat working. when the unit is running, if you can get your hand on the larger refrigerant line under the black insulation, it should be cold, about 55 degrees.
