Why Is My Furnace Making a Loud Noise?
Your home’s furnace is going to make some noise when it’s operating. You can expect a dull roar as the burners light up and the fan pushes warm air through the ducts. However, if you start hearing sounds that seem to be out of the ordinary, that’s when it’s time to bring in heating and cooling professionals from Guaranteed Comfort Heating & Cooling to inspect, diagnose and address the issue. The following are some fairly common furnace sounds that should be cause for alarm.
A Booming Sound Coming From Your Air Ducts
If your air ducts are weak, damaged or too small, they can make a loud booming noise when the furnace turns on. This is because the heat from the furnace is changing the pressure in the ducts and causing them to flex.
Our HVAC professionals at Guaranteed Comfort Heating & Cooling in Windsor can address this problem in a number of ways from sealing and insulating ducts to patching up weak sections.
A Bang When Your Furnace Lights Up
If your furnace burners are caked in dirt, they can have a tough time igniting. The furnace will slowly fill up with gas, oil or propane, and when the burner finally catches, it causes a mini-explosion.
You can avoid this problem through yearly inspections and maintenance work from Guaranteed Comfort Heating & Cooling.
Rattling and Scraping Coming From Your Furnace
While these sounds can indicate a variety of issues, the bottom line is that they are almost always a red flag.
Rattling can be caused by components that have become loose. Fixing it might be as simple as tightening a few screws or bolts. If you hear scraping, especially metal against metal, it indicates that an interior component is in need of repair. It could be the motor.
