The time has come to sort out my house for winter and summer.

Need two units, one for the lounge and one for our room. Room is ~20 sqm and lounge around 25 sqm but has open spaces leading to other areas of the house, so I'm thinking 12,000 BTU for the room and 18,000 for the lounge.

Who would you guys recommend for supplying and installing? And what sort of prices would be the ballpark?

Needs to be inverter units and wired to the DB. I'm not fussy about brands, just whatever will be the most reliable and least disruptive in terms noise etc...

I went with AC Direct. They had the Samsung AR4500 18,000 BTU for R12,999 which seemed like a very good price. Took the installation and warranty as well.

Problem is I only got told afterwards that they don't wire it into the DB, their installer isn't qualified for electrical installations. Now I need to get a sparky out to do that part sigh...

A 18000btu can work off a wall plug iirc.

yes. an 1800 btu runs at around 9 amps if running higher its overgassed ...but it should be on a dedicated socket outlet because of the initial startup or locked rotor current.which can be as high as 49 amps so 2.5 mm wire minimum or 4mm preffered.on a well maintained unit it will run at around 7 amps on a regas i fill to 8 amps unless its a full vacuum and recharge then its by weight.startup current is usually around 14 amps well within a standard SABS socket outlets rating .

It can but I prefer it on a dedicated breaker because of the startup amp spike. The last thing I need is to fry my TV...

your startup is less than a home air compressor the power still comes from the same phase so it wont influence anything electrically but an aircon on an isolated supply is allways better just make sure the breaker is a 5kva breaker and not a 2.5kva and you wont have issues .also a dedicated in dist board lightning arrester is recommended

hahaha i like the way you answer questions .thats why if youre arc welding in the garage you turn your fridges off as well as aircons the continual spike will pop the compressors .

No... appliances running inverter technology have a much lower startup surge if at all. 1.5x running load normally. But some newer ones does not go above running amps on startup.
I run my not inverter 18 000 btu aircon of a plug for the past 15 years with no problem. Actually legislation only require that for 24 000 btu and up.
 
Nice, I have 2 x 24k BTU Samsung inverters and then I recently got a 12k BTU Midea for my office. The Midea we ran off a plug. The other is wired to the DB.

we do lots of non invertors off a plug never had issues .these days the problem comes in with the wiring of newer houses they use 1.5mm where 2.5 mm is ideal for a aircon .1.5 can still handle the current but i personally dont like it
