Why is my Fujitsu air conditioner not cooling or heating well?

Several factors can affect performance: check if the air filter is clogged with dirt; ensure intake grilles and outlet ports are not blocked; confirm proper thermostat temperature settings; check that windows and doors are fully closed; during cooling, check for direct sunlight entering through windows; disable heating equipment or computers that may add heat to the room; and verify the unit is not set to Super Quiet mode, which reduces output.

How does a Fujitsu air to water heat pump work?
