What is R32 refrigerant and why does Fujitsu use it?

R32 is a refrigerant with significantly lower environmental impact than older refrigerants. It has 67 percent lower global warming potential than R410A and requires 10 to 15 percent less refrigerant charge for the same capacity. R32 also offers superior heat exchange properties for more efficient cooling and heating performance.

Can I control my Fujitsu air conditioner with a smartphone app?

Yes, compatible Fujitsu air conditioners can be controlled using the FGLair or AIRSTAGE Mobile app on your smartphone or tablet. This allows you to operate your air conditioner from anywhere, adjust settings, and monitor operation. A wireless LAN adapter is required, which may be built-in or available as an optional accessory depending on your model.

What sounds are normal from my Fujitsu air conditioner?

Several sounds are normal during operation: water running in the pipe during operation and shortly after shutdown; refrigerant circulating for two to three minutes after you turn the unit on; slight squeaking as the front cover expands or shrinks due to temperature change; and sizzling sounds during heating mode caused by automatic defrosting.

How does a multi-zone Fujitsu system work?

A multi-zone system connects multiple indoor units to a single outdoor unit, allowing independent temperature control in different rooms or areas. Each zone has its own thermostat, so you can set different temperatures in each room. This allows you to cool or heat only the areas you are using, saving energy compared to whole-house systems.

How does a Fujitsu air to water heat pump work?

A Fujitsu air to water heat pump extracts heat from outdoor air and transfers it indoors using heat pump technology. The system requires only 1 kW of electricity to generate 3 to 5 kW of heat energy, substantially reducing primary energy usage compared to conventional heating methods.
