The timing between filter cleans can vary depending on how often you use your air conditioner, but it is recommended every two to four weeks with regular use. If it has been a year or more since your air conditioner was installed, consider getting it serviced by an air conditioning professional. Not only will the system run more efficiently, cooling your home better, but it will also extend the life of your system.

Yes, operating air conditioning unit in set hours can can definitely help save energy and money. Setting the timer will minimise the hours your air conditioner is in use.

Inverter air conditioners use a variable frequency output to control the speed of the compressor. The compressor is then able to ramp up and down to meet the cooling or heating load. When the cooling or heating demand is met the compressor will slow down, in return reducing running costs. Inverter air conditioners reach the desired room conditions faster, and then constantly adjust to maintain the desired set point. Inverter air conditioners are more economical to operate and quieter to run than fixed speed units but need to be correctly sized. All Mitsubishi Electric Air conditioners come equipped with inverter technology.
