Here’s how to troubleshoot strange furnace sounds or noisy furnace ducts

All HVAC systems, to a degree, make noise while operating. However, how do you know if these noises are normal or an indicator that something is wrong? If you’re hearing strange furnace sounds or experiencing noisy furnace ducts, it could be either business as usual or a sign of trouble. In this article, we’ll review the wide variety of sounds that your furnace and air ducts can make, and which ones should lead to you giving us a call for furnace repair here in Buffalo and Western New York.

Start by ruling out potential furnace problems

Before you start thinking about what sounds are coming from your ducts, you’ll want to rule out that the sounds are coming from your furnace. There are several different furnace sounds that signal potential trouble. Here’s why you need to keep an ear out for popping, screeching, and rattling.

Popping Sounds

The sound of a loud “pop” coming from the furnace could be a sign that the furnace is igniting too much gas in the combustion chamber. In most cases, the root cause of this issue is a defective gas valve or dirty burners. Basically, what you’re hearing is a (small) explosion inside of the furnace.

This is something that you’ll want to get checked out by a gas furnace professional. Eventually, the furnace flame sensor—a safety mechanism that checks for the presence of a flame to ignite the gas—may kick in, shutting down your furnace.

Screeching Sounds

A loud screeching sound is not a natural part of a furnace’s cycle. It’s probably an issue with the blower fan’s belt. As these belts age and wear, they begin to fray and cause strange sounds. If you’re hearing a distinctive screech coming from your furnace, it’s probably not something you want to ignore for too long. Call our team and have us out to inspect the system.

Rattling Sounds

Chances are that you do not have a rattlesnake in your furnace, so the likely culprit of a rattle is something that is loose. The furnace produces a harmless low-frequency hum while in operation. Anything that’s loose—from screws and components to the heat exchanger itself—could start rattling from this natural vibration. Again, this is something you’ll want one of our technicians to help you diagnose. The rattling of a loose part is typically an early warning for an impending breakdown.

Diagnosing the sounds made by noisy furnace ducts

Now that you’ve eliminated the possibility that the noise could be generated by your furnace, it’s time to turn your attention to your ducts. Here are some of the most common sounds made by noisy furnace ducts while your heater is running.

Banging Sounds

Once you’ve ruled out the sound coming from the furnace itself, the next likely explanation of a loud popping or banging sound is the ducts. As hot air enters a cold duct, the metal expands and warps in response to the sudden temperature change. This leads to the metal “banging” as it shifts into place. This same phenomenon occurs when a duct, once filled with hot air, cools down after the furnace has been shut off. This sound is pretty harmless, and it’s natural to hear it whenever your furnace turns on or off.

Rattling Sounds

The rattling noise is most often caused by loose metal ducts that tend to knock against one another. This could be a sign that your ducts have leaks or gaps between them, which will ultimately have a negative impact on the performance and efficiency of your heating system. As ducts age, the connective sealing between them begins to deteriorate or loosen. This isn’t going to cause a breakdown or anything, but it’s still worth having a Reimer technician look into this winter.

Vibrating Sounds

A sound of vibrating or shacking of the duct walls normally occurs due to the blockage of the return side airflow. This usually happens due to a clogged filter that results in a drop in the air pressure that makes the duct walls vibrate and shake.

Booming Sounds

A loud booming noise coming from the ducts typically emanates from the plenum where all the ducts meet. This connecting point tends to endure the greatest swings in temperature. Inadequate expansion of joints or dampers contributes to the noise. What you’re hearing is a loud boom echoing through the supply ducts.

Whistling Sounds

In some cases, you can hear a whistling or rumbling noise emanating from the ductwork. The whistling noise is normally caused due to excessive airflow through the ducts. On the other hand, the rumbling noise could be due to pressure differences between the supply and the return ducts.

Cure the summertime blues with a new AC system, installed by Reimer

Western New York is not known for its sweltering summers, but it does get warm enough here to notice if your air conditioning unit is no longer pulling its weight. After years of protecting you and your family from the uncomfortable effects of heat and humidity, your old unit might not be able to keep up. You may need a new AC system.

Air conditioners eventually start running less efficiently and may do so for years before failing. You may begin noticing higher electric bills in the summer or your AC unit struggling to keep your home at the
desired temperature.

With a new AC system, you will start to see and feel some immediate benefits. Here’s what you can start to expect with new AC installation from Reimer:

Depend on having a working unit

It is a nice feeling to wake up every day knowing that your AC is far, far less likely to cause you trouble.

Getting rid of that old air conditioner and replacing it with a new AC upgrade could save you more time, irritation, and discomfort than you initially realize. A new system—with a new manufacturer’s warranty— gives you the peace of mind that if something does go wrong, you are adequately covered.

Stretch your energy dollars

As your older unit starts working harder to cool your home, you may start noticing your electric bill climbing.

By taking the energy-savings step of investing in a new, more energy efficient model, you should see your electric bill falling back in line and allowing you to keep more of your money for summertime fun.

Enjoy better cooling

An air conditioner is supposed to get your home to a cool and comfortable temperature and keep it
there, no matter what the weather outside is doing. If the temperature inside your home noticeably
fluctuates during the day, it is probably time to consider replacing your existing unit.

Don’t do it yourself: the dangers of DIY plumbing repair

The Internet has profoundly changed our lives. Of its many impacts, one of the most significant is that millions of people now have instant access to tutorials, videos, and instructions on how to do or build things themselves.

Don’t pour boiling water on your pipes to unfreeze them.

From building your own coffee table to “lifehacks” that turn old bike handles into in-style wall decor, “Do-It-Yourself” (DIY) is more popular than ever. Here’s where you should draw a line, though: unlike bottles recycled into planters, DIY plumbing repair is never a good idea.

In this blog, we’ll go over why you should only trust your plumbing repair needs to a professional plumber who has the right equipment, training, and more to get the job done.

Situation #1: Frozen pipes

Every winter here in Buffalo, frozen pipes pop up all across the city. And, every winter, homeowners decide that they want to take matters into their own hands. In one of our previous posts, we addressed why this is bad idea. Put down the hairdryer or—especially—the blowtorch and call Reimer, instead.

Seriously: no blowtorches.

Any kind of “hack” for unfreezing your pipes could make the situation a lot worse. Frozen pipes are very volatile: the expanding ice has placed the pipe material under immense pressure.

A professional plumber has the equipment and finesse to gently thaw the ice and relieve this pressure with no further damage to the structure. Other methods, however, risk the pressure building further and the pipe bursting. Not good!

Situation #2: Drain cleaning

As plumbers, we believe that it’s important to know what you’re getting into before each and every project. Drain cleaning is a good example: we use equipment to figure out what is down the drain before we attempt to remove it.

Many homeowners resort to using store-bought chemicals. Here’s the thing, though. If these chemicals are harsh enough to eat through whatever’s down there, aren’t they harsh enough to also damage your pipes? The answer is yes, which is why we think drain cleaning chemicals should be rarely used, and only as a last resort.

Instead, call Reimer. Our plumbers have a variety of professional snake tools that we use to clear drains, depending on what the obstruction is.

Situation #3: Re-piping

The popularity of home renovation shows on TV has prompted a number of homeowners to try to give their own property a makeover. That’s great: as long as you enlist the help of some professionals, opening up that kitchen will really bring your home up-to-date.

However, there’s two areas where you should really call in a specialist: plumbing and electrical. Reimer can help with the former. Moving pipes, sealing pipes, and any kind of re-piping should really be left to the experts.

The last thing you want is to get everything the way you want it, go to turn on the water supply to your home again, and disaster strikes. It’s just going to ruin everything you worked so hard for, and it can be prevented by calling in an expert.

DIY some things, call experts for others

Sure, there are some things that homeowners should try taking on themselves. However, we recommend calling Reimer if you get in over your head, or if you’re tackling something big, potentially dangerous, or technically complex.
