Good place to start is to check the coolant level and make sure its using the correct type of coolant and properly mixed for protection. Won't hurt inspect for a clogged heater hose/core-feel the hoses should be the same temperature if not something is wrong.
Could be also air mix or blend door not opening due to a malfunctioning actuator or vacuum or hose problem
