7 Strange Noises That Call for a Furnace or Air Conditioner Repair

HVAC systems sometimes hum to remind you that they’re running, but hearing such a sound isn’t always a cause for concern. However, it’s a different story when they suddenly make abnormal sounds. If you hear any of these noises, it means you need to call a technician and schedule a furnace or air conditioning repair:

7 Strange Noises That Call for a Furnace or Air Conditioner Repair

1. Popping

If your system uses metal ducts to circulate conditioned air around your home, you might hear pops from time to time. Explosion-like sounds might be unsettling, but they’re usually not that serious. Normally, it signifies that the metal is expanding and contracting from extreme temperature swings.

2. Clanking

Clanking is a sign that some parts are loose. Out-of-balance components clank when they rub against one another. Hearing some clanking shouldn’t compel you to panic right away, but the situation would only get worse when left unchecked.

3. Banging

Loud banging is indicative that something’s broken. It’s your unit’s way of telling you that you need a new crankshaft, piston pin, connecting rod, or even compressor.

4. Clicking

Air conditioners click when they start to run or shut down. However, intermittent clicking could suggest electrical issues. It could mean that your thermostat or control is shot, but you can’t diagnose your unit’s true problem without a professional inspection.

5. Rattling

A rattling noise is not a harmless sound to your AC. When something rattles in your system, it implies that there’s a tangible obstacle to its operation. When the noise originates outside, there might be trapped debris. But when it comes from the inside, call a technician and leave your system off until help arrives.

6. Whistling

High-pitched whistling is the menacing sound of a refrigerant leakage. Don’t use your unit until a professional checks it to avoid putting your family’s health in jeopardy.

7. Hissing

Hearing hisses is catching air in the act of leaking out of the ductwork. This is particularly true when the noise is coming from the walls. When the hissing isn’t loud, it still pertains to leakage but not concerning to airtight filters.
