Get rid of the Smell from the air con - indoor unit (Hong Kong air con)

Why my air con smell?  - Hong Kong air con

One of our customer told us, there's smell from the air con we cleaned few months ago. He told us yesterday while he turn on the air con , the air con has a moldy smell come out from the indoor unit. But in this few months he has never use this unit which locate in the guest's room. 

After the inspection, we did not find any dirt on top of the air con unit, The fan of the indoor unit is clean, the coil and water tray also clean. So we turn the unit is heating mode and spray disaffection alcohol on the coil and let it run for 5 - 10 mins, the alcohol kills the mold inside machine and it won't hurt the coil. 

To avoid smell problem happen like above, you could switch your air con on even two week for 30 mins in dry mode. (no condensation while u turn that on dry mode)

Air Con not turning on - split air con repair -E1 error

Air con on for 1 minute and turn off by itself - Air conditioner repair

Our customer is using a cassette type air con and after replace insulation foam, the air con switch off by itself after 1 min, we found out the signal wire is not working properly so it can;t tell the outdoor compressor to run. For the auto protection function, the indoor machine send signal to circuit board to stop the unit. The error fm the machine show " E1" error, which could be few reasons. After we replace new wire , the problem solve. The air con work again. 

How To Identify Your Air conditioner - Heating and Cooling System (Hong Kong)

Is my Air conditioner Heating & cooling or only cooling ? 

Recently, One of our customer told us her air con is not generate heat air during this cool weather. So we went to her place to check the air con, we found her air con function are Dry/ Fan / Cooling. There is no heating function of this unit. Mostly the air con in Hong Kong market is cooling only because of the long summer. 

To find the type (heating & cooling , Only cooling) of your air con 

1: there has  information label of your air conditioner at the left hand side/ bottom to tell you the model number of this unit. You could check the model number online to find out the what function your air con provide. 

2: In the label above, it usually tell you what the cooling capacitor it has provide every hour, if it only said cooling function, and did not mention heating. That means it is cooling only. 

3: For heating and cooling air conditioner, the outdoor air con require a water tray to hold condensation, so if you see there are water pipe at the outdoor unit, it mostly is a cooling and heating unit.(a small amount customer also install water tray for their outdoor unit because it was too rusty)
