Thermostat problem..or something else


I have the thermostat set on 74 in the day time. My wife came home and the temp was on 74 and the AC was not on. She said it was a little warm in the house and put it down to 70! Two hours later when I got home from work the house was freezing! You could feel it when you walk in. I went upstairs and looked at the thermostat..it was still saying it was 70 degrees in the house! There is no way it was still 74. The AC was running for over two hours and you mean to say it didn't knock the temperature down at all ?

So what's going on here? Faulty thermostat or is there something else wrong ?? AC and house are 9 years old, replaced the thermostat in 2006.

Go to Radio Shack, and get a thermostat with remote sensors. Then place them around the house to find out what the ambient temp. is. How big is the house, and what size in tons is your outside unit? I would suggest bumping the thermostat down a degree at a time, instead of dropping it four degrees like it was.

We have a Town House, it is like 1600 square feet. The thermostat is in the living room, 2nd floor. We have our garage level, then our 2nd floor (living area, kitchen) and our 3rd floor (bedrooms.) I was actually considering going to get something to take the temperature to see what it really is.

The wife goes to extremes. She'd have the thing on 68 if it was up to her. I like it 73-74. I'm just surprised it didn't drop at all in 2 hrs.. not sure about the size of the unit outside.

My fault..it was still saying it was 74 in the house...so the temperature did not drop at all in 2 hours.

Start by posting the temp of the return air, the temp at the register closest to the AH, outdoor ambient and humidity.

That's only a start but it's good first order sanity check on the basic operation of your system.

Has the performance of the system degraded over time or all of a sudden.

How hot was it outside.

maybe it was too hot outside to drop the temp.
