My AC thermostat is set at 83. Temp in house is saying 89. Humidity in CYV by my clock on wall says 55-56. I am not at the house and I just had a friend check it out for me.
Question is: Is this too big of a variable between set temp and actual temp that is being read on the thermostat? Since I am not at the house at this time, I am wondering if all is OK. Villa is only <5 yo. Never had any problems before and I actually have never noticed what the variable is before the unit comes on, when I am there It's always been fine.
Any thoughts would be appreciated. Thanks.

I would say you have a problem. Temperature in my house is very consistent to set temperature on thermostat, never 6 degrees warmer.

It is definitely not OK. The temperature in the house should be within one degree or so to the thermostat setting. The first thing I would do is to verify the actual temperature with another thermometer. Then turn down the thermostat to 80 degrees and see if the AC unit comes on. Also, check the breaker to see if it is tripped and check the condensate drain line to see if it is clogged.

If the house is less than 5 years old, the HVAC system should still be under warranty. If it is a Carrier Unit, you can write down the model number and the serial number from the inside air handler unit. Then, go to the Carrier warranty website and it will tell you the exact status of the warranty.

Did the friend mention whether both the inside and outside unit were running and whether they felt cool air from the vents?

At that differential I would expect the unit to be trying to cool the house.

I have had the blower fan stop working - the outside unit was running but no air was moving through the coils.

I have had the drain line clog and the float switch turn off the outside unit - the inside unit was running and moving air but the outside was not.

A common issue is the starter capacitor at the outside unit - the inside unit would be running and moving air but the outside unit would not. In this case, you might hear a hum at the outside unit.

There have been a lot of lightning storms this year. It is at least possible that the breaker for the outside unit might have tripped. Easy enough to look in the breaker box.

I see an A/C repair service in their future.....

Check your smart thermostat setting's would be a basic starting point? If not the issue then you should probably have a pro check it out.

I posted last month my A/C thermostat is 5° off reading higher than temp recorded by 2 digital thermometers and one analog. A/C thermostat set at 83° whole home is 78, 47% humidity.

If you are seeing a difference between another thermometer and the thermostat reading, calibration of the HVAC thermostat may be off or accidentally set incorrectly.

If the temperature displayed on your Ecobee thermostat is incorrect, follow these steps to correct it:


1) Go to the main menu on the thermostat.

2) [Select “Settings” > “Installation Settings” > “Thresholds” > “Temperature Correction.”

3) Adjust the temperature correction value to calibrate the sensor.

I read the question, but if the inside temperature is 89 degrees, it sounds like the AC is not working at all. My unconditioned garage has a temperature of 89 degrees. That is why I suggested turning down the thermostat to see if the AC kicks on.

Plus, the original post mentioned the "actual temp that is being read on the thermostat." It is the thermostat that is reading an inside temp of 89 while being set to 83, not a separate thermometer.

On my ecobee thermostats at both houses the temperature difference between the set temperature and the actual temperature recorded on the ecobbe unit is never more than 2 degrees - if I have not changed the settings recently.

You both may be right, the post is ambiguous (to me) about what/where the lower temperature is being measured.

I read the post as the separate in house measurement was a thermometer with the humidity gauge.

Lots of good advise here, hopefully the OP will figure it out.

If your humidity is staying under 60 I think you will be ok until you get back. I have had a bad thermostat that I had to replace and currently I can get several degrees difference in various rooms. But to be save seems like you need someone to verify that the A/C is running and cooling the home. For now ask your friend to turn the temp down to say 70. Then see that the fan comes on in the heater and that the outside air compressor is working. That may answer your question. Espically if the temp does not start dropping.
On my heater their is a peep hole that I can look into the heater and see the current code. The code could be a good or bad one and they may change. Your friend can try and find the peep hole. Look up the manual on the internet for what the codes mean.
My guess is you might have a bad condenser (outside unit) and this is rather easy to fix. I am guessing this as your unit is not too old.

I would call for service

Have your Person check to see if AC is running constantly, but not cooling the house..That will be an ugly electric bill. Happened to us while we were away bill was over $300. yep we had a leak chuck farrel came out next day and fixed it.
