Hi guys, I've got an electric 2005 York Heat Pump/AC split system that won't blow hot. All winter long I've avoided using the heat, now that I need to turn it up the kids are crying that it blows cold air. Pulled the '05 electronic thermostat off the wall to reset it, then turned the temp to 72 and waited; blew cold air until it got down to 68, then shut it off once more. Full service June 2006, no issues found; no reset button on unit, climbed around the attic for no apparent reason. Heat Pump model #E2RC048S06G. Checked breaker on both master box as well as AC unit, no issues found. HELP!!

Call for service.
