Household projects basically no maintenance, can be used like a household split air conditioning, regular cleaning filter can be, if the air outlet blowing out of the wind has a bad smell, you can filter cleaning the inner heat exchanger, geographically different, air quality, etc., according to the actual situation of the maintenance. Water system air conditioning may be regular maintenance every year, because there are places where the water quality is relatively hard, scaling in the pipeline directly affect the cooling and heating effect.
