I replaced my thermostat a couple of months ago(honeywell round digital) with a Hunter non-set back thermostat and with central air I'm experiencing long (mostly 1-1/2 hr. on and similar off times) run and off cycles.
I don't remember having this with the old thermostat. It use to run approx. 30 minutes on and similar off cycles. The a/c unit is running great putting out cold temps. 2 1/2 ton unit but it seems to get very umcomfortable when running and then the long "stuffy" off period.
I tried replacing it with another of the same type and no difference in performance. I do have it set with the 1 degree variance instead of 2.
Any ideas would be appreciated
p.s. I usually keep the setting at 75-76 degrees during the day.
