No one wants a noisy furnace that keeps them up all night in Westwego, LA. Though some level of noise from your HVAC system is normal, an increase in volume or the introduction of new sounds always warrants a call to an HVAC professional. Keep reading to learn more about some strange furnace noises your Westwego, LA heating equipment might make and the causes behind them.

1. Squealing Startup

A furnace that whines or squeals at startup is likely doing so because of a problem with the belt. The belt may be wearing out or becoming loose due to age. This problem doesn’t require a major repair, but it should still get fixed by an HVAC professional.

2. Buzzing or Humming

If your furnace sounds like it’s run by a hive of bees, there’s probably a simple problem to blame, like a loose door or screw. The furnace filter may have also gotten installed incorrectly and need adjusting. If these simple fixes don’t help, give us a call as soon as possible.

3. Flapping

If you hear a flapping noise while the system is running, that is probably due to a small object that got sucked in through a vent. This isn’t serious and can get remedied during a fall maintenance appointment. However, it has the potential to be more serious if you neglect removing the object.

4. Grinding

Grinding sounds while your furnace is operating is a sure sign that you need heating repair. The blower bearings make the system grind when they’ve become worn down over time. Leaving this isn’t an option; worn-down blower bearings will eventually damage other system components.

5. Scraping

A scraping or screeching noise is likely the blower wheel wearing down and beginning to shed small metal pieces into your system. Catching this early is key to avoiding costly repairs or replacements down the road.
