Furnaces make some noise, but strange sounds often mean trouble. Let’s check out some common causes of a noisy furnace and how to quiet things down in your Odessa, TX, home.
Banging and Clanking
Loud bangs or clanks might mean your ductwork is expanding and contracting, and this is pretty common when the furnace first turns on. It could also mean a loose panel or a broken part inside the furnace. If the noise continues, it’s best to call an HVAC service technician to look into what’s happening.
Screeching and Squealing
High-pitched squeals usually point to a problem with the blower motor. The bearings might need oil, and the belt might be loose or worn-out. A slipping blower belt can also cause a screeching sound. Don’t ignore these sounds as they can lead to bigger problems if you don’t fix them.
Rumbling and Grumbling
If your furnace makes a growling sound, it could be a burner problem. Dirty burners can cause delayed ignition, which leads to a rumbling noise. This can also be a safety hazard, so it’s important to have a service technician clean and inspect your furnace regularly.
Whistling and Whooshing
Airflow problems often cause whistling or whooshing sounds. A clogged air filter is a common culprit. It restricts airflow and makes the furnace work harder.
Check your filter monthly and replace it when it’s dirty. Leaky ducts can also cause these noises, so make sure the seals are intact.
Popping and Crackling
Don’t worry too much about popping or crackling sounds as they usually happen when the furnace heats up or cools down. In most cases, it’s just the metal expanding and contracting. However, if the popping is excessive or accompanied by other noises, it’s worth investigating further.
If your furnace is making any of these strange noises, it’s always best to call a licensed and experienced HVAC service technician. Call WTR (WTR) to schedule our heating services. We can diagnose the problem and make sure your furnace is running safely and efficiently.
