Air duct cleaning in West Lake Hills can reveal problems that are impossible to spot from the room below. At Andrew and Sons Air Duct Cleaning, LLC, the inspection starts where homeowners usually cannot look, inside the ductwork, around the air handler, and inside the plenum. That is often where years of dust and debris tell the real story.

What Andrew Looks For Inside A West Lake Hills Home

Most homeowners never see the inside of their ductwork.

They see the register on the ceiling or wall. They change the HVAC filter. They notice dust on the furniture. But the part of the system where dust and debris can collect is usually hidden behind the vent, inside the return, or around the air handler.

That is where Andrew starts.

Andrew & Sons serves West Lake Hills as part of its greater Austin service area. Before cleaning, the company says its lead technician inspects the ductwork for dust buildup, blockages, visible damage, and signs of wear.

That inspection matters because not every dirty looking vent needs the same work.

Sometimes the problem is straightforward buildup.

Sometimes the ductwork itself is damaged.

And sometimes the homeowner has been looking in the wrong place entirely.

The Plenum Is One Of The First Places Andrew Checks

The plenum box sits at the air handler. It is not somewhere most homeowners ever think to look.

Andrew & Sons has photographed what this area can look like before and after cleaning. In one documented Central Texas job, dust and debris were visibly caked across the plenum box before service. The same box was photographed after it had been cleaned and sanitized.

That is a much better way to understand duct cleaning than looking at a clean register and assuming the entire system is clean.

The company says the plenum is one of the first places Andrew opens during an inspection because of its location at the air handler and the conditions inside Central Texas homes.

If you are in West Lake Hills and have never had the inside of your system inspected, this is one of the areas worth checking.

A Real Round Rock Job Shows What Can Be Hiding

Andrew & Sons has documented a Round Rock air duct cleaning job where the system had not been cleaned for years.

The company photographed the condition before cleaning and again after the work. The difference is visible. Dust and debris that had accumulated inside the system were removed, giving the homeowner something concrete to compare instead of simply being told that the ducts were dirty.

That approach is important.

A homeowner should be able to ask, “What did you find?”

The answer should come from the system itself.

Andrew & Sons also publishes photographs from actual Central Texas jobs rather than relying only on stock images. Its project gallery includes before and after duct cleaning photos, duct replacement work, and dryer vent cleaning.

What Happens During Air Duct Cleaning?

Andrew & Sons cleans the system one vent at a time.

The vent covers are removed and cleaned. The company then connects a powerful hose from its van mounted vacuum system. A rotating brush at the hose head agitates dust and debris so the vacuum can pull the material out of the ductwork.

The team also cleans the area around the vents as the work progresses.

At the end, Andrew & Sons performs a walkthrough and shows the homeowner what came out of the system.

That last part is worth asking about before you hire any duct cleaning company.

You are paying to clean something you generally cannot see. Being shown the condition of the system and the material removed gives you a much clearer picture of what the service actually accomplished.

Does Your West Lake Hills Home Actually Need Air Duct Cleaning?

There is no reason to clean ductwork simply because a calendar says it is time.

The EPA says there is not enough evidence to recommend routine duct cleaning for every home. Instead, homeowners should consider cleaning when there is substantial visible contamination or another specific reason to have the system inspected.

That is why an inspection is more useful than an automatic cleaning schedule.

You may have recently remodeled and have construction dust inside the system.

You may have pets and find significant pet hair and debris around the returns.

You may have moved into an older home and have no idea when the ductwork was last cleaned.

Or you may simply open a vent and find more buildup than you expected.

Those are situations where looking inside the system can tell you much more than guessing from the condition of the room.

Cleaning Is Not The Same As Replacing Ductwork

This distinction can save a homeowner from paying for the wrong service.

If the ductwork is dirty but structurally sound, cleaning may be appropriate.

If the ductwork is torn, crushed, severely damaged, or contaminated in a way that cannot be properly addressed through cleaning, replacement may make more sense.

Andrew & Sons documents both types of jobs. Its project gallery shows failed ductwork being removed and replaced with sealed, insulated duct runs. One customer originally called for duct cleaning, and after inspection and photographs, the decision was made to replace the ductwork instead.

That is why Andrew’s inspection comes before the cleaning.

The goal is to determine what the system actually needs.

What About Dust, Allergies And Indoor Air?

This is where homeowners should be careful with big promises.

Cleaning your ducts does not guarantee that allergies will disappear or that every indoor air quality problem will be solved.

Dust can enter a home from many sources. Outdoor air, people, pets, furnishings, cleaning activity, construction and other factors all contribute to indoor dust.

The EPA also notes that the relationship between duct cleaning and health outcomes is not fully established.

What cleaning can do is remove accumulated material from the parts of the HVAC duct system that are cleaned.

That is a much more useful claim because it is tied to the actual service.

And Then There Is The Dryer Vent

Andrew & Sons also handles dryer vent cleaning, and the company’s documented jobs show why this service deserves more attention.

In one Cedar Park job, the homeowner called because clothes were taking two cycles to dry. The company found a substantial amount of lint inside the vent line.

Other documented dryer vent work has involved a bird nest blocking a side wall vent cap and long roof runs where lint can accumulate. Andrew & Sons notes that upstairs laundry rooms often have longer vent runs that travel up and over the house.

These are not problems you can solve by cleaning the lint screen.

The lint screen is only one part of the system.

If clothes that normally dry in one cycle suddenly need two, the vent line is worth checking. Andrew & Sons specifically identifies multiple drying cycles as one of the clearest signs of a restricted dryer vent.

Air Duct Cleaning And Dryer Vent Cleaning Are Different Jobs

It is easy to lump these services together because both involve hidden ductwork.

They are not the same thing.

Air duct cleaning deals with the duct system connected to your heating and cooling equipment.

Dryer vent cleaning deals with the exhaust line carrying hot, moist air and lint away from the dryer.

Both systems can develop blockages.

Both can be difficult for a homeowner to inspect completely.

And both can benefit from professional cleaning when an inspection shows significant buildup.

Andrew & Sons provides both services in the greater Austin area, including West Lake Hills.

What Should You Ask Before Hiring An Air Duct Cleaner?

Start with one question.

“What did you find inside my system?”

A reputable company should be able to explain what it inspected and why cleaning is recommended.

Ask which parts of the system will be cleaned. Ask how the dust and debris will be contained. Ask what equipment will be used. Ask whether the company will show you the condition of the ductwork before and after the service.

The EPA also recommends asking a duct cleaning provider to show you contamination that would justify cleaning and to explain the methods it will use.

Andrew & Sons says its process includes an initial inspection, detailed cleaning, cleanup, and a final walkthrough showing the homeowner what came out.

That gives you a much better basis for deciding whether the service is necessary.

Why West Lake Hills Homeowners Call Andrew & Sons

Andrew & Sons is family owned and based in Round Rock. The company says Andrew has more than 25 years of experience working with Central Texas duct systems, and that he works the jobs himself.

The company also publishes photographs from real jobs.

That includes dirty and cleaned plenum boxes, duct cleaning, failed ductwork being replaced, and dryer vents packed with lint.

For a service where most of the work happens in places homeowners cannot see, that documentation matters.

You can look at the company’s real job gallery before you call and see the type of work the team actually performs.

Frequently Asked Questions About Air Duct Cleaning In West Lake Hills

What is air duct cleaning?

Air duct cleaning is the removal of accumulated dust, debris and other material from accessible parts of a home’s HVAC duct system. A proper inspection helps determine whether cleaning is warranted and which areas need attention.

How often should air ducts be cleaned in West Lake Hills?

There is no single schedule that applies to every home. The EPA does not recommend routine duct cleaning for every household. The condition of the system and the presence of substantial contamination are more useful factors when deciding whether cleaning is needed.

How long does air duct cleaning take?

Andrew & Sons says a typical Austin home with one system can take about two to four hours, depending on the number of vents and the amount of material collected in the trunk lines. Larger homes and homes with two systems can take longer.

What does Andrew look for during the inspection?

The initial inspection checks for dust buildup, blockages, visible damage, and signs of wear or needed repair. Andrew & Sons also documents inspecting the plenum and other accessible areas of the system.

Can air duct cleaning fix an HVAC problem?

Not necessarily. Dirty ductwork and damaged HVAC equipment are different problems. If the ductwork itself is torn, crushed or badly damaged, replacement may be more appropriate than cleaning. Andrew & Sons documents both cleaning and duct replacement projects.

Does air duct cleaning remove all the dust from a home?

No. Dust enters homes through many sources, including outdoor air, occupants, pets and household activity. Cleaning the ductwork addresses material inside the system being cleaned, not every source of dust in the house.

What are the signs that a dryer vent needs cleaning?

Clothes taking two cycles to dry is one of the clearest signs. A hot laundry room, restricted airflow at the outside vent, a burning smell, or visible lint around the dryer can also justify an inspection.

Should I clean my dryer vent every year?

Andrew & Sons recommends annual dryer vent cleaning for most households. More frequent cleaning may make sense for homes with heavy laundry use, long vent runs, roof vents, or frequent loads of pet bedding.

Does Andrew & Sons serve West Lake Hills?

Yes. West Lake Hills is listed among the communities served by Andrew & Sons across the greater Austin area.

Will Andrew & Sons show me what was removed?

Yes. The company’s stated process includes a final walkthrough where the homeowner is shown what came out of the system. Andrew & Sons also publishes before and after photographs from actual jobs.
