Its one thing if you just need to pull the covers up. Its an entire different problem if your heating system is working improperly or not operating at all.
With a little do-it-yourself experience you can fix and repair your heating system yourself. Your best choice though is to have an upkeep check list for your heating system to avoid the problem.
Today I have something that will make you seem like you have the knowledge to take on some heater repair work.

Furnace is not producing heat - try to reset the Circuit Breaker
Here are any number of small reasons that this might occur. Initially verify that the thermostat is set to "Heat." Then attempt moving the dial up or down a few degrees to inspect if a noticeable difference is felt.
If there is no outcome check to see if possibly a circuit breaker or fuse was tripped or blown.

Manually evaluate the breaker. Turn it back and forth.
Make certain it is staying in the "On" position.
This will reset the breaker. If this does refrain from doing the trick you have an issue with either the electrical wiring in the circuit or the circuit breaker itself.
The heater is not producing sufficient heat. Check and change a stopped up filter.
A furnace that has a hard time to produce heat is a various matter from one that has somehow quit working.
In the case of a poor-performing furnace that does not warm the home sufficiently first ensure that the air filter is tidy and in good condition if not new.
