Any time a sudden change in the function of your home’s heat or cooling system happens, seek out the help of a repair technician as soon as possible.
If you’re wondering, “Why is my furnace so loud all of a sudden?” The answer could be a number of factors, including a stuck igniter, damage to the unit’s motor, or other potential concerns. Fortunately, an AC repair company in Las Vegas, NV, can help.
Hear a Noise – Call for Help
Before doing anything else, if you hear any type of change in the function of your HVAC system, call a heating or air conditioning repair company for fast and reliable service.
Our team will give you insight over the phone on what steps you should take. Most often, you will want to follow these guidelines after contacting us:
- Turn off the system at the thermostat.
- Switch off the breaker if possible.
- Avoid turning it back on until you have the system inspected by a licensed professional.
This is important for numerous reasons. If the igniter is stuck, there is a high risk of carbon monoxide buildup in your home, a life-threatening situation that could warrant calling the fire department after you leave.
The sooner you call our technician, the faster we can provide guidance on the best steps to take right now to protect yourself with our satisfaction guarantee.

Furnace Conditions that Could Cause a Loud Noise
A variety of factors can cause changes in the way your heating system operates, which can change the overall sound of it. Most often, this indicates you need to have your system inspected by a licensed technician to determine if there are any issues.
Consider the following common causes of sudden noise changes in a furnace:
- Humming sounds: A low humming sound is normal, but if that sound gets louder, it may be due to changes in the blower fan or capacitor, both of which need inspection. Repairs to the blower motor are common.
- Popping–like sounds: A popping noise is likely to be a new change in operation. This could be due to sediment building on the gas burners. The debris will pop when the heat comes on.
- Buzzing sounds: A buzzing, or sometimes a rumbling sound, can occur for a variety of factors, but often is due to a component becoming loose, causing vibration. Many of the electrical components can become dislodged over time, causing this.
- Scraping sounds: Scraping sounds typically are the result of wearing on the ball bearings. In other cases, it could be due to the blower wheel not remaining tightly in place.
- Shrieking, loud noises: This is one that is sure to get your attention and often means that there is a belt that is dislodged or damaged. Catching this early is critical to protecting your motor.
Any sound that changes, even seemingly becoming louder than it was, should be inspected. If you notice that your furnace is loud suddenly, chances are good that it has been occurring for a long time, which could mean it is changing significantly.
For an inspection and repair, turn to a technician from Ambient Edge, and be sure to ask about our 10-year warranty.
You May Not Hear a Change in Some Cases
When your system’s sound changes, it is a warning sign not to be ignored. However, you cannot assume the system is operating properly if you do not hear anything. It takes routine inspections and annual preventative maintenance to keep your system running properly.
It is quite important to do this consistently because of the risk of carbon monoxide buildup. As an odorless, colorless gas, it can infiltrate your home’s air supply and spread rapidly through the HVAC. A carbon monoxide leak can be hard to notice, but it can also be fatal if you or your family breathe it in for any length of time.
In some cases, you may feel that your furnace is loud all of a sudden due to damage to the heat exchanger, but other times, there is no change.
This is one key reason to have a tested and working carbon monoxide detector in your home: to detect these gasses immediately. If your system sounds off, leave the home and call the fire department.
