Customer Question

When I turn my house AC on, air flows out of the vents but it is not cold.
JA: Soon. I'm trying to find the right HVAC Technician for you right now. As soon as they are ready, I will let you know.
Customer: The condensor outside is not running.
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: Yes I did. I'm seeing a strange 'STG1' on the display
JA: Do you plan on doing the work yourself?
Customer: I'm thinking I may have hit a wrong button or something. I've never seen that on the display before
JA: Anything else we should know to help you best?
Customer: I also changed the filter
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and then connect you two.

Hello, tell me a lot about your technical skill sets and if you have a multi meter or not, and if you can the brand and model number of the thermostat, its on the back after you pry the thermostat from its wall mount plate,

We can go from there.

Hello Phil-I would say I'm reasonably handy but I do not have much experience with electrical work. I do not have a multimeter. However, if a quick fix is possible I can purchase one.The thermostat is a Comfort Stat CP2801.Thanks

Hello again,

Here is the manual for that thermostat. See the right hand column under "heating System" it describes the "stg1" message as a normal operating signal.

Follow this instructions and let me know in detail how it goes on your end.

we can go from there without a time limit.
