Check the heater control valve and the air blend door/actuator to include the heater core-

At the firewall there are two heater hose. One of it would have a valve that is controlled by a cable. Ensure the valve is fully open when heater is used.
Did you try back flushing the heater core? they can get clogged up pretty bad if coolant was not replaced previously.
