How Do I Know If My Air Ducts Need To Be Cleaned?

Air ducts are part of your home HVAC system, but most of the time they remain out of sight and out of mind. They do need regular cleaning, however, and neglecting this important task can lead to all kinds of problems, from higher energy bills to allergies and respiratory problems among the residents of the house. In fact, these are some of the warning signs which tell you to call in the professional air duct cleaners.

This is why it's important to learn the answer to how do I know if my air ducts need to be cleaned? You may also have a related question: how do I go about cleaning them? Below, you'll find a list of things to look out for if you think your air ducts may be due for a cleaning. But, when it comes to cleaning them, it's a task best left to the professionals. They have the right tools, equipment, and training for the job.

5 Signs That Your Air Ducts Need To Be Cleaned

Your HVAC system is the heating, ventilation, and air conditioning system for your whole house. It circulates air through all the rooms, keeping them warm or cool according to the season. Ironically, even though the HVAC system is responsible for keeping your home comfortable and ventilated, it can do the opposite if neglected. Dust, allergens and other particles collect in the air ducts and can cause all kinds of problems.

How Do Air Ducts Get So Dirty?


The HVAC system is essential for any home, but it's also one that is usually neglected. An HVAC system that's functioning efficiently doesn't get much attention from homeowners. This means that very few people actually get their air ducts cleaned on a regular basis. This lets the dirt inside the air ducts build up to the point where it begins to cause noticeable and serious problems.

When your home HVAC system is installed, the air ducts are sealed to keep the heated or cooled air from leaking and to prevent dust and other indoor air pollutants from entering the air duct system. But, over time, dust, mold, dander, and other indoor air pollutants manage to creep into the HVAC system, which then carries these contaminants throughout the whole house.

The HVAC system is essential for any home, but it's also one that is usually neglected.

Another way that dust and other harmful particles get into the air ducts is if you've had any construction or renovation projects done in the house. Even if the workmen take great care to seal off rooms and to clean up after themselves, the HVAC system is not airtight, and some construction debris will end up there. Many construction materials use chemicals that can be harmful and even dangerous to breathe, and if they enter the air ducts, they can circulate through the whole house.

Eventually, the dirt, dust, and debris in the air duct will begin causing problems that you will notice. If you're wondering how do I know if my air ducts need to be cleaned, here are five of the warning signs that you will see.

Signs That Your Air Ducts Need Cleaning

It can be difficult to tell if the air ducts are dirty because they're so inaccessible. But, there are some signs that you can watch out for, and the five most important ones are shared below.

1

Dust Around Air Vents And In The House

If you notice dust and debris around the air vents in the rooms, it indicates that there are contaminants in the air ducts. These may eventually start blocking the flow of air through the air ducts and causing allergies and respiratory illness in residents of the house.


You may also see the dust on surfaces all over the house, even if you clean very often. If you remove a vent grill, you may see dust and dirt adhering to the inside. This is one answer to your question, how do I know if my air ducts need to be cleaned.

2

Your Heating And Cooling Bills Spike Suddenly

There's another important sign that will tell you how do I know if my air ducts need to be cleaned. When dirt, dust, and allergens begin to accumulate inside the air ducts, they block the flow of heated and cooled air. This means that the furnace and air conditioner have to work much harder to achieve the right temperatures. The extra effort will show up on your bills as increased energy consumption.

3

People In The House Start Developing Allergies And Respiratory Problems

With all the dust, dander, allergens, and other contaminants circulating through your house, you may notice that people start developing allergies and respiratory problems. These may include unexplained sinus problems, asthma, or other respiratory problems. In extreme cases, you may also notice red and itchy eyes, sneezing and breathing difficulties.

4

Mold Is Found In The Furnace Or Air Conditioning System

Homeowners are advised to get the furnace and air conditioning system cleaned twice a year. These service visits can also help HVAC professionals to discover the growth of mold if and when it occurs. If they do find mold, chances are that it has also made its way into the air ducts.


Mold can cause serious health problems, such as respiratory illness, eye and throat irritation, rashes and itchy skin, and infections in people with compromised immune systems or chronic lung disease.

5

Signs Of Rodent Or Insect Infestation

If you see any signs or notice bad smells that indicate the presence of rodents in the air ducts, these should be treated as a health emergency. Dropping and debris like this can cause serious health problems. You should call in certified HVAC professionals to clean the ductwork.

Should You Clean Your Air Ducts Yourself?

 All of these signs will tell you if your air ducts are due or past due to be cleaned. This is not a DIY yourself project, and for the reasons given below, it's best to call in trained and qualified professionals for the job.

Why Air Ducts Need Cleaning

Keeping the air ducts clean has several benefits for you and your house. First of all, it will lead to a big improvement in indoor air quality and, consequently, in your family's health. Next, it will improve the efficiency of the HVAC system as it heats or cools your house.

This will make the house more comfortable. When the furnace and air conditioning system have to do less work to function efficiently, their life span is extended. And finally, by keeping the air ducts clean, you're preventing major blockages and expensive repairs at a later stage.

Even though it's an important task, cleaning air ducts is not something you should do on your own. Specialized tools and training are needed, and there's always the risk that you may make things worse instead of better.

Why You Should Call In The Professionals

It may be tempting to treat this a do-it-yourself project, but this is definitely one of those cases where it's better to call in the professionals. Doing it yourself may well make the situation much worse. HVAC professionals know the details of each system, and they have the right equipment and training to clean the air ducts.

When hiring HVAC professionals to clean your home's air ducts, look for their NADCA certification. NADCA is the National Air Duct Cleaners Association, and their certification will mean that the job will be done correctly and safely.

When cleaning, the HVAC professionals may also re-seal the joins in the ductwork. This will keep more dust and dirt from entering the air ducts, and it will also keep the cooled or heated air in the ducts from leaking and being wasted. This will keep the air ducts cleaned and also make your HVAC system more energy efficient.

Conclusion

With air ducts, like HVAC systems, a little preventative maintenance can prevent any major problems. It can help to maintain the indoor air quality in your home and keep the HVAC system functioning efficiently which in turn helps in lowering energy bills. Once you learn to recognize the signs that tell you how do I know if my air ducts need to be cleaned, the next step is to schedule a professional cleaning.

You have just experienced a failure of your HVAC system.

Do you check things out and handle it yourself or should you call a professional?

The answer to that question and many more you have about your HVAC system are just a scroll away.

Keep reading to discover everything you ever wanted to know about HVAC systems and how to maintain them.

The HVAC Mystery -- Exposed

HVAC stands for heating, ventilation, and air conditioning. Essentially, your home's HVAC is its temperature control system.

It's what keeps your home cool in hot weather and warm in cold weather.

It is the saving grace on days when temperatures go super high or super low and keeps you from sweating it out or ending up with icicles for fingers.

The fact is:

We use our HVAC system practically every day. And until they break down, we barely think about them.

That needs to change.

You should appreciate the modern HVAC system because, in the past, things weren't always so comfortable.

How they've changed

The idea of heat has been around since fire was discovered. Early people probably built fires in their caves to combat the cold in winter. They huddled around it to protect themselves because they likely had experienced what happens when the human body gets too cold.

woman feeling cold gif

Image via Giphy

On the flip side:

Someone once probably waved their hand in the air and discovered it provided a cool bit of air

Ancient times

Ancient people in Greece and Rome also appreciated warmth. They actually created fire channels that ran under marble flooring to provide radiant heat. These were like the low-tech version of today's radiant flooring.

And that's not all:

The Romans also had the hypocaust, which was similar to the central heating units of today that use radiant heat. They were on top of staying warm and toasty.

Fun Fact: The Romans were the first to use a warm air heating system.

The Egyptians didn't forget about cooling, though. They are famous for their man-powered fans.

These early attempts were okay, but better things were on the horizon.

1400s

Leonardo Da Vince continued with the idea of using a fan for cooling, but he didn't need to enslave people to make his fan work. It ran on water power.

This century didn't really expand on heating. The focus was more on ventilation at this point.

People had long been cooking with wood stoves and were getting pretty darn tired of smoke-filled homes.

With the advent of the chimney, it meant the smoke could flow outside.

Blessed ventilation.

Fans were also used to help remove toxic gas in mines, helping to make mining safer for workers.

1500s

Chimneys came to America in the 1500s, and mines in France really began using fan technology, expanding on the previous decades' inventions.

This century also brought the introduction of the gravity exhaust ventilation system.

Plus, Galileo invented the thermometer.

Finally, people had a way to tell just how hot or cold it was, but his thermometer wasn't really accessible to everyone.

You've probably seen the modern version of a Galileo thermometer.

Back in his day, though, it wasn't as easy for the average person to read.

For that, people had to wait until the 1700s.

1700s

We'll skip the 1600s because there isn't much that happened on the HVAC front, but in the 1700s inventors really got back into the swing of things.

Daniel Gabriel Fahrenheit introduced the mercury thermometer in 1714.

Now, when Aunt Tilly complained about being chilled, you could check the thermometer, see it was 70 degrees, and tell the lady to put on a sweater because you weren't about to fire up the wood burner.

The first centrifugal fan ventilator came out of this decade, too.

But wait, there's more:

Benjamin Franklin invented the first steam heating system, and direct fired heat exchangers were first used in England.

The 1700s also brought us the boiler system and hot water heating systems.

Yay! No more heating pots on the stove and lugging them to the bathtub!

1800s

By the 1800s, things were heating up.

In 1861, William Siemens invented the electric furnace that had heated coils and fans.

Fun Fact: While Siemens electric furnace may have been a thing in 1861, but electric in homes wasn't. By 1925, only half the homes in the U.S. had electric.

The first blast furnace came in 1885 from inventor Fayette Brown.

1900s

You could say the 1900s were a real boom for HVAC. So much happened that the whole concept of HVAC was forever changed.

Here's what happened:

In 1902, Willis Carrier created air conditioning using coils, refrigerant, and a fan. However, it wasn't until 1906 when Stuart Cramer coined the term air conditioning.

So, before then, I guess people called it the cool air thingy?

Fun Fact: Because air conditioning hadn't been invented yet, schools started giving children a break over the summer because the schoolhouses were too hot.

By the 1920s, people had air conditioning in their homes, but it still wasn't feasible for many people due to cost. So, it became huge for movie theaters to install air conditioning systems and use the cool air to entice patrons inside.

Fun Fact: AC in movie theaters lead to the creation of Summer Blockbusters because so many people went to the movies in the heat of summer.

AC was first put in vehicles in 1939, but it was such a huge hassle people really didn't want to deal with it. You had to get out of the car to turn it on and off.

No thanks. I'll just let the wind cool me off.

In the 1930s, J.Q. Sherman and H.H. Schultz invent window air conditioners to really help spread this invention to the masses.

Fun Fact: Herbert Hoover installed AC for the first time in the White House.

The 1900s also was when the heat pump became a thing. It was a more economical way to heat and cool a home.

In 1998, due to environmental regulations, there was a need for a new type of refrigerant. So, the Carrier Corp introduced Puron refrigerant.

By the end of the decade, solar-powered HVAC units were introduced to help save energy and make use of this renewable energy source.

2000s

Renewable energy is still a popular idea. Geothermal energy systems are being introduced.

One of the most popular...

Zoned systems. These let you control the temperature in each area of your home instead of having one control for the whole house.

Talk about ideal comfort level.

Plus, many systems are Wi-Fi enabled, and you can control them remotely through your smartphone.

It really is the future.

HVAC sure has come a long way since people used open fire to stay warm and hand-held fans to stay cool.

Getting the Right Temperature

The whole point of an HVAC system is that it works properly to provide you with a temperature-controlled environment. An effective HVAC system will keep your home cool in warm weather and warm in cool weather with proper ventilation for excellent indoor air quality, no humidity, and no dryness issues.

This is a tall order.

To ensure effectiveness, your system needs the right components and set up to suit your home and needs.

HVAC Components

Regardless of how complex or high-tech a system is, it will have four main components:

  • 1
    Source
  • 2
    Delivery system
  • 3
    Ventilation
  • 4
    Control

The source will be your furnace, boiler, heat pump, and air conditioner.

A furnace is a forced-air system that runs on electric, natural gas, propane, or wood. It blows air with a fan through vents in your home to deliver the heating.

A boiler is radiant heating. You will have a radiator delivery system.

A heat pump works in conjunction with a furnace. It will either take air from the ground, air or water and heat or cool it based on your needs. It
uses your general heating system delivery method.

Fun Fact: You can save up to 40 percent on energy costs by using a variable speed heat pump.

An air conditioner uses a condenser and evaporator system to cool and remove moisture from the air that it delivers to your home. Depending on the type of air conditioner, it may use the same vents as your furnace or blow out directly from the unit using a fan.

Fun Fact: A home feels cooler with lower humidity levels. This is another way air conditioning makes your home comfortable.

Every system will also include proper ventilation. This removes air from your home, remove byproducts of the heating and cooling process, or filters the air coming into your home.

The good news is:

Ventilation is usually built into the heating or cooling source.

But the control panel depends on your system set up. Often it's mounted on the wall or the unit and allows you to set the desired heating or cooling level based on what temperature you want your home to be.

Your system will surely include various other components, but may not include all of these components. For example, some systems don't include an air conditioner. And some may have a fan built in that you can operate independently of the furnace. Or you may not have a central unit that delivers heat but instead use electric heaters in each room of your home.

There are many ways to design an HVAC system using various components.

How they work

Just as all HVAC systems have the same general components, they also work in much the same way. The general concepts of heating, cooling, and ventilation do not really change.

Here's an idea of how each element in an HVAC system works.

Controls: A control panel that allows for temperature setting for heating and cooling. May also provide fan control.

Heating: Heating options are usually a furnace or boiler.

A furnace uses vents that run throughout the home and blows air from the furnace into the vents with a blower fan.

A boiler uses pipes that send heat to radiator units in each room of the home.

Air Conditioning: Air conditioning removes heat and humidity from a home and introduces dry, cool air.

Ventilation: Ventilation is built into the heating and cooling units to remove hot or cold air and to remove byproducts of the heating and cooling process, such as carbon monoxide and smoke. It also includes things such as kitchen and bathroom exhaust fans and ceiling fans. Some systems may also remove allergens, dust, and dander.

Keeping Things Working

You can get the best possible HVAC system installed in your home, but it still won't last forever.

I know -- bummer.

Just as with a vehicle, you have to do HVAC maintenance on your HVAC system regularly to keep it running right.

Fun Fact: Energy efficiency is a huge deal. Due to standards from the U.S. Department of Energy, from 1993 to 2003, people saved $29 billion on heating and cooling.

What and why

You should get your HVAC system maintenance done twice a year. You want to do it before each major season, which is summer and fall.

Pro Tip: Have your HVAC system maintenance in late winter and later summer to avoid the rush and ensure you can get an appointment.

In addition to those two routine checkups for your system, you should also change the filter monthly or every three months, depending on your use.

Here is a checklist of the tasks that should be done during the bi-annual maintenance.

hvac maintenance checklist

Clean blower assembly

Clean burner assembly

Wipe down exterior shell

Check for combustible material around unit

Clean combustion blower housing

Wipe down exterior shell

Check ductwork for leaks and blockages

Inspect electrical components and tighten or replace as needed

Flush and treat drain pan

Check tightness of flue system

Check for gas leaks

Inspect heat exchanger for damage or leaks

Adjust ignition system as needed

Lubricate motor

Check motor belts

Test safety devices

Adjust gas pressure

Test thermostat

Check tubes for damage

Inspect fan blades for wear

Check refrigerant pressure level

You should be aware there is not an industry standard for what is included in bi-annual maintenance. So, make sure to check your agreement with your technician to see what he or she is doing on each visit.

Typically, a technician will do some basic tasks each season.

For the AC in the spring:

The technician will probably tighten electric connections, inspect controls, clean coils, lubricate as needed, replace worn parts and the filter, check the fans, check pressures, and verify the operating temperature.

For the furnace in the fall:

The technician will likely tighten electrical connections, inspect for leaks, clean the blower, clean the burners, inspect the ignition switch, clean the flue, replace any worn parts, and inspect the controls.

Benefits of HVAC Maintenance

You want to do regular maintenance to keep your furnace running properly and to avoid safety issues.

Maintenance also helps to prevent costly repairs, lowers energy bills, and helps your system last longer before you need to replace it.

Fun Fact: Proper maintenance can help prevent up to 35 percent loss of heat.

Here's a deeper look at the benefits of regular maintenance.

Efficiency

Your home will be more comfortable all year long.

Safety

A properly running system is a safe system. Gas leaks or carbon monoxide build-up can be deadly. In addition, there is also the risk of fire in an unmaintained system.

Saves money

You'll find you have fewer repairs, lower energy bills, and the system will last longer.

Better air quality

A good working system can remove contaminants more effectively.

More environmentally friendly

When you use less energy, it benefits everyone and everything on Earth. You have less exhaust from your system when it is working at peak performance and use less fuel.

DIY vs. Professional

When it comes to maintenance for your HVAC system, you may wonder if you can do it yourself or if you should hire a professional to do it for you.

If you have training and skills in HVAC, you may be able to do it yourself.

But how many of us do?

Not too many.

Your best bet is usually to call in a pro.

However, there are some tasks that you can DIY.

Just make sure you understand the difference between those things you can do and when you need a professional.

Listen up:

Working with gas and electricity is dangerous. If you try to do something that you do not have the skills to do, it could be a deadly mistake.

In this case, it really is better safe than sorry.

I can do it myself

One of the things you can do yourself when it comes to maintaining your HVAC system is taking care of the filter.

Not only should you change it regularly so you aren't running a system with a dirty filter but also you should consider using high-efficiency filters.

Here's why:

The filter keeps dust out of the system. It ensures the system runs more efficiently and prevents breakdowns due to dust buildup.

You can also keep the area around your unit clean. Dust, debris, and dander are no good when they pile up around an open flame. All it takes is one wayward spark to send your home up in flames.

Also, pay attention to operating sounds. You can often tell if something isn't quite right by just listening to the unit when it's running.

It's also fine to check things out visually. Look for damage or wear.

Not only that:

Stay alert for odd smells, too. Gas leaks are nothing to play around with.

Now, DIY can be great for many things:

  • Building a shelf
  • Painting the bathroom
  • Installing a new sink

But it can also be bad for other things, namely maintenance on your HVAC system.

Professionals go through quite a bit of training to learn how to work on these systems.

They learn about safety. Not only how they can stay safe while working but also how to ensure a system is safe to use.

Making a mistake by trying to do repair work yourself can cost you big time.

If you don't happen to get injured, you could break something and end up having to replace the whole system.

And that's pricey.

Plus, most warranties are only valid if a professional technician works on the unit.

If all that is not enough, you could also get yourself into some legal trouble.

imprison woman gif

Image via Giphy

It's true!

There are laws about handling refrigerant and working with other parts of the system. If you don't know the law or have the proper training or licensing, you could end up in jail for your DIY escapade.

I need some help

So, are you good and scared about trying to tackle HVAC maintenance on your own?

scared family guy gif

Image via Giphy

That wasn't the point, but at least you understand trying to do it yourself is a risky move.

You should call in a professional to do the bi-annual maintenance of your system at a minimum, but you may also call a pro to do any repair work, as well.

Here's what to leave to the pros:

  • Thermostat calibration check
  • Electrical connection tightening
  • Lubricating
  • Inspection and cleaning of the condensation drain
  • System control check
  • Blower cleaning and adjustment
  • Evaporator and condenser coil cleaning
  • Refrigerant check
  • Fuel line checks

When choosing someone to work on your HVAC system, make sure they are licensed to do so in your state if required.

gavel icon

Legal Fact: Most states do require licensing for HVAC professionals. In states that don't, some local governments may require licensing.

Icon via Flaticon

Also, check their experience. They should have years working on systems either as an apprentice in training or on their own.

Make sure they are insured as well.

You can also look for someone with certification from a professional organization, such as North American Technician Excellence.

And it never hurts to get referrals and references, too.

Don't hire just any old Joe off the streets, people!

Replace or repair?

Whenever something is giving you a fit, you usually stop and think if it is worth repairing or if you should just buy a new one.

When it comes to the HVAC system, buying a new one is a huge investment, so you need to think about this for a bit.

Think about this:

There are some common signs it might be time to replace your system instead of doing another repair. These include:

  • It's over 10 years old
  • Repair costs are over 50 percent of the replacement cost
  • It's outdated, and parts are difficult to find
  • You have rising energy bills
  • It's no longer properly heating and cooling your home
  • You have humidity issues
  • It's constantly breaking down
  • You have dust issues
  • It's excessively noisy

Obviously, if you have a newer system, you will always go with repairing it over replacing it.

There is an exception:

If you're moving, ignore everything above and do a repair instead of replacing it.

It usually is not worth it to replace the system as it won't help with the sale of your home or get you more money on your asking price.

As long as it is safe, fix it and move on.
