Replaced filter. Cleaned drain, panel, flame sensor and inducer port. Cleaned condenser coil. Checked all operations. System can fail at anytime because of bad capacitors. Put blower speed in high for cool mode. Adjusted grills. Bedrooms are cooler, but this might not be enough. Next option is duct repair or dampers to push more air to bedroom. Home owner rents out bedrooms. Not interested in IAQ at this time.
