4 Furnace Noises You Should Not Ignore

A furnace is known for making strange and popping noises during normal functioning. As a homeowner, you are accustomed to such noises and should be able to detect any unusual or weird noises coming from your furnace. 

The good thing is that each type of noise has a specific reason that may or may not require professional assistance. This article aims to share general information on common malfunctions of furnaces that can produce weird noises from the heating system.

Normal Sounds Produced by a Furnace

Popping of the Ducts

New or cleaned ducts produce a loud popping sound when switched on, which is completely normal. It is heard when the blower fan is switched on, which increases the pressure inside the duct and creates a popping sound.

Click Sound When the Furnace Ignites

A single click heard after switching the on and off the furnace is completely normal. If the clicking sound persists, it’s likely due to fan malfunction and requires professional assistance. For furnace repairs in Ardmore, OK and surrounding areas, contact Allied Services/Hoyle Holt.

Chirping Sound When the Ignition Starts

Dust starts accumulating inside the furnace and the ducts when you do not use your furnace for a long time. It’s normal to hear a chirping sound when you first switch on your furnace after a few months, which usually resolves after cleaning. Schedule a professional tune-up and cleaning services just before the onset of the winter season to enjoy maximum benefits.

Four Furnace Noises You Should Not Ignore

Squealing Noises When the Furnace is Switched On

A high-pitched squealing noise is a major concern and requires professional servicing. A worn-out component, usually a motor fan or a blower, is responsible for the squealing noise. You should switch off the furnace and quickly contact Allied Services/Hoyle Holt for heating services in Ardmore and the surrounding areas. The expert will assess the full system and probably suggest the replacement of the broken component. 

Loud Popping Sound When the Furnace is On

Continuous loud popping sounds require your attention and call for action. Over time dust and dirt accumulate over the ignition chamber that causes a delay in the ignition. The burning of gas produces a loud noise that can damage the chamber and the heat exchanger.

Further, if you have metallic ducts, expansion and contraction of the ducts can produce a loud popping sound. In both these cases, it is advised to switch off the system and call for professional servicing. For heating replacement in Ardmore, OK, contact Allied Services/Hoyle Holt for the best solutions.

Scraping Noises are Coming From the Furnace

Scraping noises are usually caused by loose, broken parts that bang against metallic surfaces. Motor fans, loose screws, worn-out belts, and broken condensers are all responsible for scraping noises coming from your furnace. They all require emergent fixes and replacements. Book your professional service appointment today to prevent further damage to your system.

Low-Pitched Continuous Humming Sound

A malfunctioning motor fan or condenser produces a low-pitched continuous humming sound that the homeowner notices. It affects the heating capabilities and substantially increases your furnace’s energy consumption, generating higher utility bills requiring costly replacement of broken parts.

Carbon Monoxide and Its Harmful Effects

Many furnaces and heaters use carbon monoxide gas to produce heat. Any cracks in the ductal network can cause carbon monoxide leakage in the air. Carbon monoxide leak is colorless, tasteless, and odorless and can be deadly if inhaled in large quantities over a while. Early symptoms of carbon monoxide include fatigue, nausea, and fainting. Contact your health physician and a professional HVAC service technician immediately if you notice any of these signs.
