What are those noises from my basement ???

Alpine Heating and Cooling • September 21, 2021

 As the temperatures drop and your furnace kicks on for the first time this year and begins it’s six month journey heating your home and keeping your family warm this winter you may hear noises you haven’t heard in awhile.

 

 
While it is difficult to diagnose an exact issue and repair needed going by the noise alone it can give you and your service tech a good starting point. Below is a list of a few of the noises you may hear coming from your 
furnace and what the issue they may be linked to.

 

 
Grinding-
 This is a telltale sign that you have a problem that needs addressed ASAP. More than likely your furnace has parts that are broken or loose and they are rubbing up against other parts. Don’t wait and give us a call as soon as you hear this sound. Additional damage and cost could add up if this is left unattended.

 


Rattling-
  If you hear a ratting noise traditionally this is not a huge issue. It could be something as small as a loose screw or something needs tightened down. You will want to get to the bottom of the situation but typically not an emergency.

 


Whistling- 
 A whistling sound is almost always a sign that you have air flow restriction. The sound you hear is your furnace trying to draw air and move it where it can’t, which creates gaps. We recommend replacing your air filter as that clears up the issue most of the time. If you replace your filter and still hear the same sound. It’s probably time to give us a call.

 


Buzzing sounds-
 Again, like the grinding this should be looked at by a professional ASAP. We’ve seen a numerous amount of these sounds end up as an electrical connection issue.

 


Banging or loud pops- 
 This sound often comes from your ductwork and typically happens when your furnace kicks on/off. This is pretty common as metal will expand and contract

 


Squealing noises-
  Belts on furnace blowers just like the belts on your car will need replaced from time to time. As they begin to wear down you may hear that annoying whining or squealing noise. when your furnace kicks on/off.

 


This is not an all-inclusive list and when in doubt give us a call and we can dispatch one of our certified technicians to come out to diagnose and repair your 
furnace issues and maybe at a price less than you expect.

Most HVAC problems don’t start with a breakdown. They start quietly—months or even years earlier—because of one simple habit almost every homeowner has. They wait until something stops working to think about their HVAC system.  HVAC Systems Don’t Fail Suddenly—They Wear Out Your furnace or air conditioner doesn’t usually “just die.” It wears down gradually through: Longer run times Higher electrical draw Rising internal temperatures Increased vibration and stress By the time a system shuts off or trips a safety, the damage has often been happening for a long time. That’s why emergency breakdowns almost always come with higher repair costs. What Actually Causes Premature HVAC Failure Contrary to popular belief, age alone isn’t the biggest killer of HVAC equipment. The most common causes are: 1. Small Issues Left Unchecked A weak capacitor, dirty flame sensor, or failing blower motor doesn’t always stop the system—but it forces other components to work harder. That added strain shortens the life of the entire system. 2. “It’s Still Working” Syndrome Homeowners often delay service because: The house still heats or cools The system hasn’t locked out There’s no obvious warning light Unfortunately, HVAC systems can operate while slowly damaging themselves. 3. Deferred Maintenance Costs More Than Repairs Skipping routine service doesn’t save money—it shifts the cost to: Larger repair bills Emergency service calls Shortened system lifespan A simple maintenance visit can prevent a $1,500 breakdown. Why Breakdowns Always Happen at the Worst Time There’s a reason furnaces fail during cold snaps and ACs quit during heat waves. Extreme weather forces systems to: Run longer Start more frequently Operate at peak capacity If a component is already weakened, that’s when it finally gives up. What “Normal Operation” Should Actually Look Like A healthy HVAC system should: Start smoothly Run consistently (not constantly) Shut off cleanly Maintain temperature without drastic swings Sound the same month to month Changes in sound, runtime, or performance are early warning signs—not inconveniences. The Smarter Way to Think About HVAC Ownership Instead of asking: “Is it broken?” A better question is: “Is it operating the way it should?” That mindset shift alone prevents many major HVAC failures. Final Thought Your HVAC system is one of the most expensive mechanical systems in your home. Treating it as something to react to—rather than maintain—almost guarantees higher costs and shorter lifespan. The homeowners who get the longest life and lowest total cost aren’t lucky.
