When the City of Ojai needed the air moving cleaner through its Public Works office, staff building, and City Hall, they called Kelly Cleaning of Ventura County. This is the story of that job. It shows how our crew handles a large municipal building, room by room, over two full days of careful work.

The Job at a Glance
On Saturday, July 11, our team went to work for the City of Ojai. The goal was simple. Clean out the air duct system that runs through three connected city buildings.
Here is what the project covered:
- The Public Works office
- The staff building
- Ojai City Hall
Everything went smoothly from start to finish. Other than the vents being very dirty, there was nothing out of the ordinary with the ventilation system. That is often the case in older public buildings. Dust and grime build up slowly over the years until the ducts are packed with it.
A public building is used by many people every single day. Staff, visitors, and the public all breathe the same shared air. That is why a job like this matters, and why it takes real planning and the right crew. Work of this size is a good example of what our commercial cleaning team is built to handle.

Why Clean Ducts Matter in a City Building
Clean air ducts help prevent health hazards. Duct cleaning can remove dust and mold spores from a building’s ventilation system. That is a big deal in a place where people work and gather all day.
Several unwanted things can hide inside a duct system:
- Allergens
- Fungus
- Mildew
- Bacteria
These particles do not just sit there. They get pulled into the moving air and spread through the whole building. Over time, that dirty air is what people breathe at their desks and in the hallways.
There is another reason a cleaning like this is smart. If a building has recently had a mold issue, or dealt with some other unhealthy problem, an air duct cleaning is highly recommended. It helps make sure the problem is fully gone and does not come back later. For a busy city office, that peace of mind is worth a lot.

How We Inspect Before We Clean
We do not guess about what is inside a duct. We look first. Our company uses video camera inspection systems to check the ductwork before any cleaning starts.
The camera helps us:
- Find blockages inside the system
- Spot problems built into the layout
- See what kinds of contaminants may be present
This step matters on a big commercial job. It means the crew knows exactly what they are dealing with before they lift a single tool. On a three-building project like the one in Ojai, that kind of planning keeps the whole job on track. It is the same careful approach we bring to our full range of cleaning services for offices and public spaces.

The Two-Day Cleaning Procedure
A job this large does not happen in an afternoon. It took two full days to do it right. Our crew followed a clear, step-by-step process across all three buildings.
Here is how the work went:
- The crew used a rotobrush system to break loose and pull out the built-up dirt inside the ducts
- Every register was cleaned and then sanitized
- The air supply source got a deep cleaning
- A sanitizing fogger finished the project by eliminating bacteria and allergens
That last step is a nice touch. The fogger reaches into corners and surfaces that a brush cannot, so the whole system gets treated, not just the parts you can see. When the crew packed up, the city’s air was moving through clean, sanitized ducts again.
This is the kind of steady, detail-driven work our janitorial team in Ventura brings to every commercial account, whether it is a single office or a full city campus.
Serving Public Buildings Across the Area
Kelly Cleaning is based in Ventura County, and we are proud to serve the towns around us, including nearby Ventura. Ojai is one of our neighbors, and being able to help the city with its buildings meant a lot to our team.
Public and commercial buildings have needs that a home does not:
- More rooms and longer duct runs
- Higher daily foot traffic
- More people counting on healthy indoor air
- Schedules that have to work around staff and the public
We plan around all of that. Our crews are used to working in real, busy buildings without getting in the way of the people who use them.
A Simple Tip to Keep Air Fresh
Good air does not stop the day the crew leaves. There is one easy habit that helps any building stay healthy between deep cleanings.
- Always change your filters every 3 to 4 months
Fresh filters catch dust before it settles back into the ducts. Thanks to the thorough two-day cleaning, the Ojai facility will not require another full cleaning for at least two years. That is the payoff of doing the job right the first time.
