While some of the noises made by your heating system are normal, it’s vital to pay attention if they change or get louder. A damaged belt or a loose component may be the issue, however, other, more significant mechanical problems may also be at play. Brief cycling, which happens when the heater turns on and off too quickly during the day and causes heating problems, is a concern with older heating systems. As a heating system warms up, it should run continuously until your house reaches the proper temperature for heating, at which time it should turn off. Suppose heating equipment turns itself back on too quickly. In that case, various issues, including worn-out heating components, blocked airflow, and even dirty air filters after furnace repair work, can all lead to heating difficulties. An expert can locate these problems and resolve them.
