1. duct cleaning

   Generally  in the air conditioning system to send, return, exhaust duct with air  flow control valve, muffler, silencer fittings, with baffle elbow and  air filter, these parts in the operation of the air conditioning system  is the most easy to adhere to dust , And it is not easy to carry out cleaning. In  some duct system only set the air outlet, no air volume control valve  and silencer device, for these places you can remove the air outlet to  check. In the air duct connection, especially the flange, the gasket is also the most easy to adhere to dust. Air  conditioning system in the run for some time, due to the fouling within  the pipeline, will affect the use of air-conditioned room effect. Therefore, regular cleaning of the duct is necessary.

   When  cleaning, you can open the duct inspection port or remove the air  outlet, into the duct to clean up, or use the scrub method, you can also  use a vacuum cleaner to clean up. If the duct can not enter, conditions permitting, you can remove the duct by paragraph cleaning and then re-install.

   2. Maintenance of ducts

   In the use of air conditioning system in the duct, insulation structure will inevitably produce some such as security

Temperature layer or moisture layer roll angle, and wood keel separation and so on. Where found the situation, that should take timely measures to repair, in order to achieve the original insulation effect. If found due to various reasons caused by the deformation of the duct,  it should promptly take remedial measures to ensure the normal  operation of the air conditioning system.
