Why Is My Furnace Making a Banging Sound in Pace, FL?

December 20, 2021

In an ideal world, all of our appliances would function smoothly and soundlessly. If you notice that your furnace is making loud noises, it’s important to find the source. It may be a sign that something is wrong with your HVAC system. Here are some of the furnace noises in Pace, FL.

Banging Furnace

If your furnace is making a banging sound, then there could be a problem with the ignition. The heating system gets a signal from the thermocouple to start a cycle, and the gas supply valve opens. The pilot light then ignites the gas immediately.

If the ignition system is faulty, gas may build up in the combustion chamber during ignition, producing a banging noise. The sound travels through the air ducts and moves throughout the house. The noise can be due to clogged burners or the pilot light burning ineffectively.

Whistling Furnace

The furnace makes whistling noises when something interferes with the flow of air. When a heating system produces a whistling sound, something is clogging or blocking the air filter. You need to clean or replace the air filters to clear the whistling sound and improve indoor air quality.

It may also produce a whistling sound because of trapped objects in the ductwork and vents. Clean the ducts, filters and ensure the vents are open to solve the whistling sound.

Humming Furnace

A humming noise from the furnace is not a cause for alarm because many heating systems hum during ignition. A new heating system may hum as the transformer tries to adjust to the current flow. If the furnace motor makes a humming sound throughout the cycle, then the motor is faulty and you should call an HVAC technician.

If the fan wears out, the furnace makes a humming sound. To identify when a humming noise is a cause for concern, listen to the volume of the hums. If the murmurs are persistent, call a technician to inspect your system.
