🔥❄️ Furnace Making a Whistling Noise? Your System May Be Starving for Air ❄️🔥

A high-pitched whistle when your furnace runs is usually an airflow warning sign. It often happens when air is being forced through a tight spot—like a clogged filter, blocked return, or leaky ductwork. The furnace may still heat, but restricted airflow can cause overheating, short cycling, higher energy bills, and premature wear on the blower motor.

At Uptown Heating & Air Conditioning, we locate the restriction, check static pressure/airflow, and restore smooth, quiet operation.

⚠️ Common Signs It’s an Airflow Problem
✔️ Whistling starts when the blower ramps up
✔️ Weak airflow from vents
✔️ Some rooms are colder than others
✔️ Furnace shuts off and restarts frequently
✔️ Filter looks dirty fast or collapses inward

⚠️ Most Common Causes of Whistling
✔️ Dirty/restrictive air filter (most common)
✔️ Closed supply vents or blocked registers
✔️ Return grille blocked by furniture, rugs, or a dirty return filter
✔️ Duct leaks or loose duct connections pulling air/sucking noise
✔️ Dirty coil or blower wheel restricting airflow
✔️ Incorrect blower speed settings / airflow not set correctly

✅ Quick Checks You Can Do (Safe)
Replace the air filter (make sure it’s the correct size)
Open all supply vents and check returns for blockage
If whistling continues, schedule an airflow diagnostic
