I seem to be allergic to mold. It causes a constriction in the lower respiratory tract and significant breathing difficulties. This makes staying in hotels with central air-conditioning rather unpleasant. Are there any workarounds? I intend to get myself tested for the mold allergies to have a clearer picture, but is there any way to address the issue?
Is it mould or "pollen" alergy?

There are Pollen Filters available in West. They just plug in the nostrils and filter out all the pollen and dust. You can try it.

Re: The home / office air-conditioner thread

Guys I need some advice on the wiring of my AC (inverter split) that was recently installed in my house.

Is it really safe to extend the original wire of the indoor unit if the 15A plug point is located slightly far from the unit? So what the AC installer has done is he joined additional wire to the original AC wire so that it could reach my plug point. Point to note is that he joined the three internal wires separately and taped them up. Should I be worried? and should I just get rid of the extra wire and shift the plug point closer to the AC? Heck, even that 'might' result in extending the 15A plug point wire, no?

Sorry, but I am complete noob when it comes to electricals.

No need to worry, as long as the electrician has used sufficiently thick wire, which he probably has.

If the wire to extend your AC cord is of same thickness or more, there is no problem. After all moving the plug will also require the wire to be extended.

The only problem that I see is cosmetic. He could have used a regular 3 core cable of sufficient thickness.

Re: The home / office air-conditioner thread

Thanks a lot guys. I am little more relieved now. I think the thickness is fine. But this reassuring. Thanks again!

Many thanks for the suggestions. Let me get myself tested first to discover the nature of the allergy.

Re: The home / office air-conditioner thread

For those looking to buy Mitsubishi Electric ac ,
ME has some models where they do epoxy coating on the indoor unit coils for anti-corrosion purposes and they specifically mention that this is keeping in mind Indian conditions where gas leakage is prevalent.
I bought their cheapest JP series non-inverter 4 years back and this model has this coating mentioned in its brochure and I have faced no problems so far.
A model above this is GK series which doesn't mention this coating in its brochure and a ME technician confirmed this saying that GK series is an older model so it doesn't have coating whereas JP series is a newer model. Although GK series has thicker copper tubes than JP series.
Top model GS series once again mention epoxy coating in its brochure.
Prospective buyers may keep in this mind.

Similarly Fujitsu General has some models without epoxy coating on indoor coils.

Also this epoxy coating is different from blue fin coating which is done on aluminium fins whereas epoxy coating is done on copper tubes and copper bends and both serve different purposes.
I think that this is the best possible option for those living in areas which are prone to gas leakage.

Re: The home / office air-conditioner thread

Folks, I am on the look out for a multi split AC. While this listed most OEM's web sites, dealer don't have them. Checked with several. DO et me know if you come across one in Blr.

Multi splits did not succeed in India. I had also looked for them a long while back and only carrier/Toshiba and O General had them, and even then getting information and quote for them was like extracting teeth, and they were not able to give even one reference where it had been installed.

A few years later I remember seeing ads by sharp for multi splits but that lasted a short while only.

I personally would not pursue this path as servicing could become a problem even if installed,

Multi split units are cheaper versions of the VRF airconditioners.

VRF (Variable refrigerant flow) support multiple IDU's and multiple ODU. They are at least thrice as expensive as domestic AC, but last much longer as they are designed for Commercial/Industrial environment.

VRF is mainly used for medium sized applications - 5T to 20T and 5 to 20 IDU. Central airconditioning on a medium scale.

Normally if you need 4 or more AC and at least 2 at a time, these systems make sense. But if you use only one AC mainly (bedroom) and a few poccationally, the these make less sense.
