Hotel-Specific Air Conditioner Cleaning "Catalyst Power" Expands Disassembly Cleaning for Concealed Air Conditioners Nationwide

HONU Inc. (Headquarters: Minato-ku, Akasaka, Tokyo; Representative Director: Kenichi Uchida / Service Brand: "Catalyst Power (HONU)" / Trade Name: "KOHKIN LAB") is expanding its disassembly cleaning service for "concealed air conditioners," common in hotel and ryokan guest rooms, to hotels nationwide. The service provides a one-stop solution, from mold removal and anti-mold treatment within the visible louvers, which are often overlooked, to the cleaning of the main unit (drum and aluminum fins). The cleaning is performed during vacant periods between guest check-out and check-in, and with a capacity to clean over 10 units per day, disassembly cleaning is achieved on the shortest possible schedule without interrupting operations.

Background: "Concealed" air conditioners are mainstream in hotel rooms, but few companies offer disassembly cleaning.

Concealed air conditioners, where the main unit is housed within the ceiling, are the standard in hotel and ryokan guest rooms. Because only the louvers are visible, it's difficult to notice accumulated dirt on the internal aluminum fins, drum, and drain area, and standard cleaning methods cannot reach the interior.

Disassembly cleaning requires specialized work to access the main unit within the ceiling, and the limited number of companies capable of this service is a challenge for the industry. As a result, issues such as reduced airflow and wind speed, decreased heating/cooling efficiency (leading to increased electricity costs), and moldy odors or returning smells tend to go unaddressed for long periods in guest rooms.

Feature 1 [Main Feature]: One-stop service from mold removal to anti-mold treatment within louvers HONU's primary feature is its ability to provide a comprehensive service that extends beyond the disassembly cleaning of the main unit (drum and aluminum fins) to include mold removal and anti-mold treatment within the louvers.

The interior of the louvers, despite being in direct contact with the guest room air during each airflow, is a narrow and hard-to-reach area that is often overlooked. If mold remains here, even thorough cleaning of the main unit will result in odors and mold being expelled into the room during operation, causing "moldy smells to return after cleaning."

HONU offers a package that includes mold removal from inside the louvers and anti-mold treatment to suppress recurrence long-term. Few companies can handle both disassembly cleaning and anti-mold treatment as a single service. This eliminates the need to divide the work between different contractors, allowing for a single point of contact to achieve a state where returning odors are minimized.

Feature 2: Cleaning performed during guest room vacancy, without interrupting operations ────────────────────────────────────────── HONU excels at performing cleaning tailored to hotel room operations. By conducting disassembly cleaning during the vacant period between check-out and check-in, air conditioner conditions can be restored without taking guest rooms out of service.

Schedules are created considering cleaning routes, room occupancy, and peak seasons, thereby minimizing operational losses.

Feature 3: Capacity to clean over 10 units per day for the shortest schedule

HONU has assembled a specialized team for cleaning concealed air conditioners in hotel rooms, with a capacity to perform over 10 disassembly cleanings per day. They can handle large-scale requests for multiple rooms or entire floors with concentrated, short-term efforts.

This allows for the planned cleaning of the required number of units without necessitating large-scale floor renovations or long-term room closures, addressing the unique hotel challenge of wanting to clean multiple rooms at once without extended downtime.

Feature 4: Reporting effectiveness with numerical data through pre- and post-cleaning airflow tests

HONU conducts pre- and post-cleaning airflow tests for all air conditioner cleaning services, reporting the results numerically. This allows for confirmation of improvements based on measured wind speed, rather than just a subjective feeling of effectiveness.

Reduced airflow and wind speed directly correlate with decreased heating/cooling efficiency, increased electricity costs, and the spread of odors. Visualizing the condition with numerical data allows for an objective assessment of the necessity and effectiveness of the cleaning.

Track Record: Over 6,000 rooms nationwide. Measured data shows wind speed recovery of approximately 4x during comprehensive guest room non-smoking renovations.

HONU has performed cleaning services at accommodations nationwide, including major city hotel chains, with a cumulative track record of over 6,000 rooms cleaned (as of June 2026).

In a comprehensive non-smoking renovation project for 21 guest rooms at a city hotel in the Kanto region, the average wind speed at the air outlet recovered from 0.50 m/s before cleaning to 2.00 m/s after cleaning (approximately a 4x increase) due to the inclusion of disassembly cleaning for concealed air conditioners. Improvements in airflow were confirmed in all 21 rooms. (※ Measured in March 2026, actual values from a comprehensive non-smoking renovation project where pre- and post-cleaning measurements were taken under identical conditions).

To customers who ask, "Wouldn't it be cheaper to hire a local company?"

HONU sometimes receives inquiries from hotels comparing cleaning costs with other companies, asking, "Wouldn't it be cheaper to hire a local company?"

HONU's accumulated know-how from past projects significantly reduces the period rooms are taken out of service. Furthermore, they can flexibly respond to any troubles that may arise during cleaning, ensuring that the process does not halt midway.

Taking rooms out of service directly translates to lost revenue for that period. By considering the total cost, including lost revenue during the downtime, in addition to the cleaning cost alone, customers can truly appreciate the value of choosing HONU.
