The cherry blossoms are over, and it’ll be getting warm soon. The days when we’ll start using the air conditioner are coming up…
Is dust or mold building up inside your air conditioner?
When you turn it on for the first time in a while, you might notice a strange smell…

Reservations already seem to be filling up this year
Don’t we all tend to rush to book air conditioner cleaning once it gets hot? According to ROKU, one of the Nishitsu Friends, reservations usually start filling up around after Golden Week, but
this year, as of mid-April, they’re already booked out two weeks ahead… Wait, already that much??

↑Whoa.This is inside an air conditioner
If you’ve been thinking, “This year I really should get it done,” it’s best to act now instead of waiting until after Golden Week.
This is how black the water gets when a pro washes it
This is what it looks like when the inside of the air conditioner is being pressure-washed↓

That black stuff comes pouring out. Thinking that this was mixing into the air in your room…
If you get it done before it gets hot and humid, you can avoid that “It stinks! Mold!” moment in summer.
What is ROKU? A local service for Nishinomiya, Ashiya, and Higashinada
ROKU is a locally based air conditioner cleaning service mainly covering Nishinomiya, Ashiya, and Higashinada.

The representative, Mr. Kobayashi, carefully cleans each unit one by one. He has been in business for 5 years and has over 10 years of cleaning experience. He is a certified air conditioner cleaning technician accredited by the Japan Air Conditioner Cleaning Association, and keeps his skills updated through training several times a year.
Another nice point is that they use eco-friendly detergent that’s gentle for babies and pets. It’s easy to request even while you’re at home, which is really helpful.
They’re also covered by liability insurance, so you can feel secure in case anything unexpected happens.
Here are the prices
Here are the prices↓
| Type of air conditioner | Price |
|---|---|
| Standard air conditioner | 9,000 yen |
| With self-cleaning function | 18,000 yen |
| Built-in wall type | 14,000 yen |
No travel fees and no extra charges. The amount you’re quoted at the beginning is exactly what you pay, so it’s reassuring that there won’t be any “additional fees later.”
Plus, there’s a small bonus right now
Anti-mold antibacterial coating, normally 2,500 yen, is free for one unit
And on top of that,
For air conditioner cleaning done on the same day, the second unit and onward are 1,000 yen off per unit
It’s a good deal if you can get multiple units done on a day that works for the whole family.
Booking through the form is recommended
You can also casually ask through the form, like “What type is my air conditioner?” or “Can you handle one with a self-cleaning function?”
By the way, Mr. Kobayashi is often unable to answer the phone while working, so
if you’re comfortable using a computer or smartphone, please use the reservation form.

Finally
Reservations are apparently starting to fill up much earlier than usual this year, so if you’ve been thinking, “I should probably get it done soon,” taking action early is the easiest option. If you’re interested, definitely take this opportunity to contact ROKU.
