I changed the thermostat in my house and the heater works fine but the a/c will not come on and I don't know why?

My a/c will not come on I changed my thermost in November the heat woks but the a/c will not?

My a/c is not working after I changed the thermost

If the A/C system worked before you changed the thermostat and it does not work now it is a good possibility you wired the new thermostat improperly or in the case of the new digital thermostats the setup directions were not followed. Revisit the install and find your problem.

Did you put in a jumper from rh to rc ? Saying this not being able to see what kind of honeywell you have
