Commercial and residential duct systems have very similar construction. However, a proair duct cleaning equipment can assist you in cleaning them both equally well. Cleaners always look for efficiency while working. Yet, identifying the differences is also a must for accurate outcomes. Knowing the ductwork and the built well helps in cleaning the parts efficiently. Thus, here we are going to aid you in differentiating between the two for more effective working.

Differences between commercial and residential ducts

There are quite a few variations between the two. Noting them is a must for all cleaners to perform well.

  1. Construction

As per studies, the construction of commercial ducts is as follows:

The construction usually uses stainless steel round or rectangular sheets. Further, metal ducts are fixed in large parts with tinier sections that make up the convertible elbow joints, leading to the ducts’ bends. The sturdy stainless steel construction assists in longer life and better durability.

Also, non-metallic ducts are extremely light and simple to change because they are built of a unique material that supports more flexibility. These ducts are finest for areas that have a larger metal HVAC system. However, using them might not be practical due to restricted space or a random pattern without or with hurdles.

On the contrary, the components utilized for residential ducts are entirely different. Also, the structure and pattern of these ducts are different from that of commercial ducts. Understanding the material type is essential to note cleaning methods.

  1.  Maintenance

The cost of keeping a building’s HVAC ductwork clean is certainly because of the extensive and vast system it has. Also, the cleaning demands expert tools for apt work.

However, you can use similar tools to clean these two ducts. Yet, the price may vary on a major basis.

  1.  Placing

Another chief distinction in residential and commercial HVAC units is where these ducts are located. Both the ductworks are located in different areas. In the case of residential HVAC systems, they are normally situated close to the ground. However, commercial HVAC systems are located on the top regions like the roof. The reasons for this elevated location are:

  • Big size
  • To perform easy cleaning and maintenance without disturbing the entire space
  • Shielding against vandalism
  • Complete safety against the interference of any kind
  1.  Parts

Both the ductwork systems are located on the inside. Yet, residential HVACs are generally in splits, which means that two systems work in compliance to heat or cool a space. The indoor components comprise the blower, condensate drain, and evaporator. At the same time, the outdoor part comprises the compressor, condenser fan and the condenser.

On the contrary, Commercial HVAC systems are generally a single unit with all these parts in one cabinet located on the outside. Only the zone dampers are placed in the building along with the ductwork.

  1.  Extras

In the case of residential units, they cannot be built upon and are standalone systems. Here both indoor and outdoor parts need to function in compliance. Also, the system demands an alternate even if there are any problems with the duct system. It comprises any alteration to metal ductwork like specific cooling and heating needs.

In the case of Commercial units, they are modular; you can change these ducts as per need. Experts can also add extra modular components and shift smaller parts of this huge unit with complete ease compared to the residential unit. Yet, these ductworks are not changed very often.

  1.  Complexity

Commercial places are more intricate and particular when compared to suburban or residential places. Buildings mostly utilize a trunk-and-branch pattern in their ducts since they are produced from silica-based glass or fiberglass vent duct boards, the expenditure of which is the least.

This fiberglass ductwork is bigger since it is prepared to heat up and cool down hugger indoor places with more tenants. Thus, the wastage structure must be larger, and a larger amount of windows are needed for the exhaust.

Housing units usually have minor ductwork structures, only one wastage system and fewer amounts of windows to reduce exhaust.  

Why is Cleansing a Vent Cleaning vital?

Sanitizing dryer vents help keep people, houses and administrations safe from hazards. Professionals advise owners to look for specialists to check vents and sanitize them frequently. It is vital to cleanse the combustible pile corner and keep other elements hygienic with the birds’ nest.  

Standard clean-up of dryer vents will advance your appliance’s operation, decrease light bills, stop vent outbursts, and improve the inside quality of air. A deficit of good air conditions can lead to harmful gasses like CO in the area.

How often must Domestic and Commercial Vent Dryers be Sanitized?

Skilled professionals recommend that domestic dryers must be checked and sanitized frequently. Therefore, owners must frequently clean away the duct channel after every vent dryer series. It will facilitate in preventing large blockages.

The vent dryer channels in commercial places and multi-residential cabins and apartments must be sanitized annually. Many organizations present discounts on the latest yearly vent dryer duct sanitizing plans.

The price approximate generally includes:

  • Multiple levels of the building structure.
  • The size of vent dryer channels.
  • The placement of exhausts.

If there are more components, the total cost will be greater. Simultaneously, the price per component reduces as the quantity of components increases. Top levels would need an additional rent for an elevator, where the owners will be charged in the total invoice later.

Leading service providers hire professionals that deal with places of all sizes and deals. Selecting yearly contracts with these organizations creates reliability and sureness with developments, making the plan simple. So, if the place is rented, you ensure protection to your renters.


Differentiating between the two is a must for efficient work. Use the assistance and vary between these duct systems to clean them well. Opt for the finest ways and get maximum outcomes. Add-on fine tools and make the most effective cleaning to make your HVAC work more powerfully. Prep yourself with the finest knowledge and offer profitable services.
