Can anybody tell me how much a typical air conditioning installation costs 12000/13000 BTU per room. Thanks.

It's a "how long is a piece of string question. Just to replace an existing, about B1,500

Are the evaporator/inside units going to be mounted on the inside of an exterior wall?

Wiil the condenser/outside units be mounted on the outside of the same exterior wall?

Is the electrical service already in place?

Are the drains already in place?

Are you replacing existing units?

Are the units to be on the ground floor?

Condo or house?

Replace existing means they take the old one out and replace with the new unit, and use the existing electric and drain and condenser mounting brackets. If you buy from HomePro or Modern Air, this type of installation is often "free".

New installation needs to have the electrical service run, and a drain needs to be installed. The drain is for the condensate/water the is removed from the air.

How far is your electrical panel/consumer unit from the AC locations, and do you have two extra breakers or space for two new breakers?

It will be a new installation. Sorry I don't know all the details. I was enquiring on behalf of somebody else. They quoted figures that seemed very high, not that I have any idea of what the installation should cost. The quoted cost to install 12000/13000 BTU between 35,000 and 42000 baht. Bearing in mind in the UK I can buy a 12000BTU A/C for 22400 baht, just all the parts installation on top then the Thai price seems very high. UK will include 20% VAT. I am guessing the basic equipment in Thailand is cheaper anyway, much larger market. Talking near on a thousand pounds to buy and install an air conditioner, I don't believe it.

Where are you?

Just order from HomePro or Modern Air.

A new 12,200 Carrier Copper 11 inverter with wifi B14,900 installed. the electric is extra.

Again, how far is your electrical panel/consumer unit from the AC locations, and do you have two extra breakers or space for two new breakers?

If you do not have enough power, and need a new service, that can cost quite a bit.

I am in the UK but going to stay in Pathom Thani. The house has no A/C at present or so I understand. The house owner offered to install A/c at the prices I mentioned. But given the prices quoted it seems a rip off.

In Pattaya installation job ( or moving an existing one to new location) 1500-2000 depending on how easy or difficult the location.

Aircon prices then another story, big variation depending on brand model and where you buy.

I am in a new to me home and we are installing all new AC.

Three 3-phase ceiling cassettes, one 60,000BTU and two 38,500BTU with wifi capable wired remotes

Three single phase 18,000BTU with wifi capable wireless remotes

Installation will be about 80,000 baht

The unit prices are 40% off list

I am seeing quotes of 30,000 baht for a single unit which seems very expensive

Do you even have enough power to increase the size of your panel?

If you need a new meter and larger service, 30K is a bargain.

You are not providing enough information to get a realistic idea of what it should cost.

I don't actually know the details, I am not in Thailand at the moment. It may well be that the price is reasonable. All I know it is a new build house in one of these villages. I will be very surprised if there was not provision for the inclusion. There again it is Thailand so I should absolutely expect the provision for A/C has not been included in the build. If 30,000 is not unreasonable at least I have something to go on.

Most A/C guys are reluctant to install only.

These guys make more money selling the air-conditioning unit plus installation.

The margin on the units from list is typically 35-55%, that's why they give "free" installation.
