Customer Question
I have a model 9500...
I have a model 9500 thermostat. The air conditioning comes on at 76 degress as set, and seems to be working OK, but the temperature on the display keeps going up and the it never cycles off. (the heat never did this). The thermostat is placed on the wall adjacent to the closet where the air unit is located. Don't know if that impacts it or not. I am sure this is gonna cost a fortune since it does not cycle off. Suggestion?

Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.
1. Is outdoor unit coming on?
2.Does air feel cold coming out of registers?
Ask Your Own HVAC Question
Customer reply replied 3 years ago

yes, to both, everything is running properly

HVAC Technician: airheatman, HVAC Technician replied 3 years ago
OK if unit is running and air feels cold, the temp should not be going up. Do you have a thermometer that you might compare to the thermostat display? Your thermostat could be wrong. Is it comfortable in the house?
Ask Your Own HVAC Question
Customer reply replied 3 years ago

No I don't have a thermometer. The house feels comfortable. The thermostat/air unit are at one end of the house. That end therefore is typically cooler, which makes the higher temp reading on the thermostat even stranger.

HVAC Technician: airheatman, HVAC Technician replied 3 years ago
Does that end seem warmer than usual?
Ask Your Own HVAC Question
Customer reply replied 3 years ago

not really

HVAC Technician: airheatman, HVAC Technician replied 3 years ago
I would start by getting a thermometer and comparing actual temp to what thermostat is reading. You may need a new thermostat.
