what is your temperture gauge show? Is it point to middle or low?

If low, it could be your themosat or there is air lock in your heating system.

Air lock means air traped in your heating system, and it cause low heat.

In that case, you have to pay someone to release the air inside the heating system.

most likely a bad thermostat.. otherwise could be a blocked heater core or air bubbles.
