Keeping the air in living environments fresh with a total heat exchange type 24-hour ventilation system.

Following an amendment to the Building Standards Act of Japan in 2003, the installation of a 24-hour ventilation system in all buildings became mandatory.
By taking in outside air after using heat exchange to bring it to room temperature, the “total heat exchange type 24-hour ventilation system” by MAX reduces the amount of energy
consumed when using the cooler or heater and elevates the level of energy-saving and comfort in living environments.
We provide various products for the needs of “replacing” equipment when renovating a house.
Of course, we have set up an after-care system to respond to the need for replacement work.

With dependable work rendered from the manufacturer itself, from repairs to replacement, our after-care system has been well-received by customers.
MAX has mechanisms and systems in place for providing after-care services, for we give consideration not only to the sale of our products, but also to what will be done afterwards.
