Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
Turn off your A/C and put your fan switch in ON or FAN. Run the fan only for approx 3 hours. Check your air filter and clean/replace as necessary. Also check your evaporator coil and clean if necessary. It is possible that your evaporator coil is frozen up from a dirty filter or coil. If it continues to be a problem, you probably have a refrigerant problem which will require a certified service technician to address. Try taking care of the filter and coil first. :-)
