Banging Sounds Coming from Your Ductwork

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air around your space, and a capacitor, which starts the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be due to something minor, like an unfastened screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating pros at 432-203-4881 for assistance.

If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We realize that maintenance frequently slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping
