The clever folks over at TipHero have a solution: Turn on your ignition without starting the engine. This might seem like it’s hindering the heat from pumping, but it’s actually the best way to get hot air quickly and, after about five seconds, you should hear the fuel pump priming the engine.
The thermostat may be stuck partly open if it takes longer to warm up than it used to as long and the outside air temperature is not below freezing. If outside air is very cold than the engine would cool down quick and take longer to warm up.

How do I know if my thermostat is stuck open?
Remove the radiator cap and idle the engine. If the coolant flows right away, your thermostat is stuck open. If it is not flowing, wait until your engine warms up. The coolant should warm to the right temperature and begin to flow after 10 to 20 minutes.

Does flushing the heater core work?
Flushing out the tubes in the heater core will allow the coolant to flow more easily so there will always be warm coolant to heat up the air going into the cabin. This is especially true if it has been a while since you last changed the coolant as all the buildup can eventually end up in the heater core.

Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn’t just work to keep the engine from overheating: It’s also the source of heat supporting the heating system. If there isn’t enough coolant in your system, the heater core will blow cold air into your car.
