Your furnace has one job—keeping your home warm and safe when the Albuquerque winters are at their harshest. But if it starts making an odd rattling noise before it blows heat, that’s a sign something’s not right.
At B. Carlson Heating, Air Conditioning & Plumbing, we’ve been helping Albuquerque homeowners stay ahead of furnace issues since 1971. We’re not just here for quick fixes—we’re here to be your trusted partner in home comfort. If your furnace is rattling, here’s what it could mean and what you should do next.
What’s Causing Your Furnace to Rattle?
Not all noises mean trouble, but some indicate a potential system failure. Here are the most common culprits:
1. Loose Panels or Screws
Albuquerque’s temperature swings mean your furnace is constantly expanding and contracting, which can loosen screws or panels over time. If the rattling sound happens before the blower kicks on, it could be something as simple as a panel that needs tightening.
2. A Blower Motor That Needs Attention
The blower motor is responsible for circulating warm air throughout your home. If it’s loose or starting to fail, you may hear a rattling noise before the heat turns on. Ignoring it could lead to reduced airflow and higher heating costs.
3. A Cracked Heat Exchanger – A Safety Hazard
A cracked heat exchanger is one of the most serious furnace issues because it can lead to carbon monoxide leaks. If your home has uneven heating, increased energy bills, or an unusual smell, it’s time for an inspection. At B. Carlson, safety comes first—if you suspect a heat exchanger issue, call us right away.
4. Expanding or Loose Ductwork
Metal ductwork naturally expands as warm air moves through it. If your home’s ductwork is older or wasn’t installed correctly, it might rattle or pop when the furnace turns on. Properly securing and insulating your ducts can help reduce the noise and improve efficiency.
