How often do I need to clean the air filter?

A heat load calculation comprises of many factors such as size of area, size of windows, roof type, building material, whether there is insulation, external shading, or internal shading etc. Incorrect sizing will lead to temperature control issues.

Question 4

Will using the air conditioners timer improve energy efficiency?

Accepted Answer

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. You can also be strategic about these timings and set the timer to turn your air conditioning on before peak heat load conditions to counter the impact of peak summer or peak winter conditions, so the air conditioner doesn’t have to work as hard.

Question 5

What is an inverter?

Accepted Answer

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.

Question 6

How do I find the model number of my air conditioner when I only have the remote control?
