Commercial units are our main focus
From restaurants and offices to clinics and care facilities, we proceed while watching the flow of business and visitors. Even at sites with many units, we organize the order to break the work into short segments.
Serving all of Hiroshima Prefecture and Iwakuni City, Yamaguchi Prefecture
We restore the air conditioning in restaurants, beauty salons, offices, and clinics from the inside out through dismantling and cleaning.
Grease in restaurants, chemicals in beauty salons, and dust in offices all create different kinds of buildup. At B.grand, we assess the installation environment and build the process for each unit, from protection to high-pressure washing.
A standard wall-mounted unit takes about two hours, while ceiling-mounted units are adjusted based on the number of units and installation height. Stores in and around Hiroshima City, Fukuyama, and Iwakuni can also consult us for schedules that fit their on-site operating hours.
In medical-related sites, retail stores, and sole proprietorships, careful work and clear explanations matter. If you share the model, number of units, and business conditions in advance, we will explain the necessary steps clearly.
We first inspect the site and check the heat exchanger and airflow path for dirt. We then remove the parts and clean them, and after completion we check drainage and airflow to finish the job.
After cleaning, odors around the outlet are reduced and airflow becomes more stable. Regular cleaning once or twice a year also helps reduce the burden during busy seasons.
From restaurants and offices to clinics and care facilities, we proceed while watching the flow of business and visitors. Even at sites with many units, we organize the order to break the work into short segments.
We clean your bedroom and children's room with the same careful process. Because you can consult us about stores and homes together, it is easier to handle travel and arrangements in one go.






In addition to locations across Hiroshima Prefecture, such as Hiroshima City, Higashihiroshima City, Fukuyama City, and Kure City, we also visit Iwakuni City in Yamaguchi Prefecture. Based on travel distance, we also adjust timings so the work can fit between store operating hours.
Even for urgent inquiries, if you know the number of units and installation locations, discussions can move quickly. If you do not have site photos yet, please start by calling and telling us the situation.
