I’m not an expert, but I’d never heard of chemical cleaning until I came to Singapore. I’ve always thought it was a scam!ttac wrote: ↑Fri, 01 Apr 2022 8:14 pmHi everyone looking for some advice.
Have been ghosting on the forums for a while..
My tenant for my place did not keep servicing records for the air con and we had to call up the aircon service to provide some documents at the end of the tenancy. Nevertheless they had not serviced it at the required intervals. The aircon service person had recommended a chemical cleaning during the 1.5 year rental period and had reflected this on the receipt. The tenant claims they had misplaced all receipts and were not told that chemical cleaning is required. From my understanding, aircon maintenance includes chemical cleaning, or am I mistaken?
That's a complete and utter load of crap. "Piping" never gets "clogged". I live in Houston, Texas, where we have much hotter summers and equal or worse humidity. Chemical cleaning is unheard of. In fact, most homes use central air conditioning, as opposed to window units or split units.ttac wrote: ↑Mon, 04 Apr 2022 1:42 pmSpoke to the aircon guy and another 2 just to be sure. apparently cos of the humidity, chemical clean is needed to take care gooey stuff become it turns into some sludge that clogs up the whole piping. They claim it's part of aircon servicing maintenance and they make recommendations as to when it is needed, which is roughly every year if aircon is used heavily.
Ouch, MD. Grab him by the cojones, you did. The OP is the Landlord apparently. Good one. Love it!Myasis Dragon wrote: ↑Mon, 04 Apr 2022 10:28 pmThat's a complete and utter load of crap.

It's almost impossible to reach the evaporator coils in a central air system because they are inside the plenum, in the attic. My central air conditioner lasted for more than 25 years before I replaced it, and the only reason I replaced the evaporator coil was that the new, more efficient system required it. It was never cleaned with anything.
Bottom line: At most, you face the possibility of having black mold grow on your evaporator coils. The solution to this is simple. Get a can of Lysol disinfectant spray or similar. With the unit running, spray the disinfectant into the intake grill. It kills the mold, and no more problem.
The only problem you might have is landlords who have been bamboozled by air con guys and insist that you, as the tenant, pay for this useless, and expensive, charge. I'd make sure that the lease says that the landlord pays for this expense, and then, I'd bet it never happens.
I had to put up with this nonsense while renting in Singapore. I paid it only because the landlord was otherwise pretty good at taking care of issues.sundaymorningstaple wrote: ↑Tue, 05 Apr 2022 6:12 pmOuch, MD. Grab him by the cojones, you did. The OP is the Landlord apparently. Good one. Love it!
