You got to the station and say "hot air recharge please". They will let you know if that's something to try. They say most of the time the recharge won't last long enough because of leaks in the system, always a big problem.

Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

Could be an air lock in the hot water system.
Normal procedure is to slacken a hose clip at the highest point and bleed the air out.
Don't try this when the engine is hot or someone could get scalded. Surprised the dealer didn't bleed the system as they would have a special radiator cap that allows the system to be put under pressure
You can try stop leak, but don't expect great results. If the leak is big enough to lose more than 8 oz in a few days, you have a major leak. And using more than one can of stop leak can cause problems in the system.
First thing to do would be check the thermostat. Sounds like it may be stuck open and needs replaced. If it sticks in the open position the engine never warms up properly an d will give you little or no heat.
This is a common problem when the AC system has a low charge. If this is the case, you have a leak somewhere. Do not try to fix it yourself without the proper equipment.
