everything worked well since this morning. For some reason, I turn off the AIR conditioner power in switchboard,then turn on the thermostat let normal air blow and clean duct. after that,turn off the thermostat. But this afternoon, I turn on the power back and turn on thermostat @ cool, my baby lennox hs29-018-1p cant start, no cold air at all. just the air form basement. must be something wrong. Any one can help me will be very appreciated.
