Mobile air conditioning units require unobstructed air flow to function most efficiently. If the exhaust is blocked, the device will shut down to prevent overheating.
Analyze the exhaust hose from the mobile ac unit into the exhaust location, typically a drop ceiling or an exhaust vent mounted in a window. Verify the hose is installed correctly and has no kinks that would interfere with air flow.
The hose should be as straight as possible as each curve increases air friction and reduces efficiency. Never stretch a hose to reach a remote exhaust port. Exhaust hoses are already as long as they have to be and extending them raises air friction.
Unit Runs Continuously or Does Not Appear to Be Cooling
The most common cause of poor mobile air conditioning system (which is also known as ” ระบบปรับอากาศ ” in the Thai language ) performance is a dirty filter. Air filters should be inspected and replaced regularly.
If the unit isn’t functioning correctly, the first thing to check for is a dirty air filter. Don’t vacuum and reuse disposable filters since it’s not possible to wash them satisfactorily for efficient operation.
Check for barriers at the air intake and exhaust. If the air isn’t flowing smoothly, the device must work harder to cool what little air makes it to the system. Something such as a desk pushed up against the air intake will inhibit the unit’s performance.
Close open windows or doors. You shouldn’t have windows open in a room with mobile air conditioning and doors should be kept shut, opened only when entering or leaving the room.
Unit Is Quite Noisy
Portable air conditioning produces a certain amount of noise, which is inevitable. But the noise level shouldn’t be jarring or be deflecting. Rattling or groaning isn’t normal, nor is a sudden increase in sound level. Noisy units are typically not flat, causing tingling. Check the unit to make it on a flat surface and isn’t touching other objects which may be vibrating.
Unit Is Leaking
Portable air conditioning produces water because cooler air holds less moisture. Some units have the ability to eliminate the moisture through the exhaust port while some have inner tanks to collect the water. Check to find out whether the tanks are full and have to be emptied. Ensure drain plugs and tank caps are secured. When relocating the unit, always empty any water tanks prior to moving.
