What You Should Do If Your Heater Is Making Noise In Norwood

Does it sound like there is something unusual happening within your vents? Are you worried your HVAC system is on the brink of a breakdown? Whenever your heater is making noise in Norwood, you have good reason to be apprehensive. Even though some sounds are part of normal operation and are able to be fixed rather easily, you might have a situation that necessitates professional attention. Learn about the various heater sounds you may hear and what you are able to do about them.

Common Heater Noises in Norwood And Reasons Why

The only sound you really want to hear from your HVAC equipment is a pleasing continuous humming that indicates normal operation. Other noises are less welcome. If your furnace gives you the impression of a plane about to take off, you may have an issue. Many noises may be put into these categories:


This is one of the most common heater noises in Norwood and may take place for a few different reasons with your heating equipment.

  • Problems igniting: Does your natural gas furnace or boiler emanate a noticeable bang when it starts? Your system might not be starting in a proper fashion and gas could be building up. When your heater ultimately gets going, the surplus of fuel is combusted, which delivers the telltale bang. Your system’s ignition ought to be examined by professionals and burners addressed if warranted.
  • Boiler issues: Air stuck inside boiler tubes may cause banging. You might need to bleed the pipes. Once you’ve turned off the equipment, rotate the bleeder valve counterclockwise to free the unwanted air. After the air is released and you notice a bit of water, turn off the valve. You may also encounter limescale buildup on the heat exchanger. This could also give a whistle like a teapot called kettling.

  • Ducts: An additional type of bang you may hear comes from air ducts. When your system functions and warm air travels across cold ductwork, it may lead to the metal expanding. Once the air stops going through the system, the ducts may contract, resulting in the banging noise. Fortunately, this is normal and doesn’t signify a problem.


In a similar fashion to the sound your car produces when there’s a problem with your belt, you could notice a squealing noise with your HVAC system. The belt that connects your fan and blower motor may get loose or slip out of place. Turn the power off, open the blower compartment, and inspect for a loose-fitting or misaligned belt. If you find in excess of a half inch of play in either direction, the belt should be realligned. Rotate the bolt on your blower assembly or place a call to Thomas & Galbraith Heating, Cooling & Plumbing for skilled help.


If your heater is making a noise in Norwood when the fan is running, you may have a problem with your appliance’s blower motor. You’ll observe a distinctive grinding noise when the motor elements aren’t appropriately lubricated. This may occur if you pass over your normal maintenance. Schedule an appointment and have the parts addressed to prevent damage to your motor.


Something as harmless as an unsecured access door may be generating a rattle. On the other hand, it might be something serious if a piece is detached in your heater. If fastening your door doesn’t solve the problem, reach out to a heating and cooling professional in a hurry.
