im looking to buy a few airconds for my home. A few 1.5hp and 2.0hp and 1 3.0hp
I've been searching online and realised there are 2 refrigerants to choose from; R32 vs R410A.
What would you recommend as I want it to be environmentally friendly ie. less toxic.
I'm looking for the inverter models to reduce electricity cost as well.
So far looking at Panasonic models.
For split unit
Pana X-Deluxe, Daikin FTKU, Hitachi, Mitsu Mr Slim (MSY P/N, not the MHI SRK), Gree Lomo Queen Inverter generally OK. Compare BTU spec for each class (1.5 to 1.5) and warranty.
For cassette or mini cassette
Choices more limited - Pana. Daikin. Mitsu. Acson.
You can consider multi split IF you are not using ALL the unit at the same time. Multisplit is somewhat more economical especially when you are speccing higher hp aircon.

R410A refrigerant models have been phased out, unless it is old stock. Most manufacturers are going towards R32 now. If you looking at Panasonic inverters,
There is the X Deluxe Inverters, Deluxe Inverters and the Standard Inverters. End of the day, it is what features do you need.
R410 may be older model but sometimes much much cheaper for the bigger unit 2hp and above cassette, can be 1k cheaper (or more) vs the R32; it may be better CAPEX to get a cheaper R410 INV than a new R32 NON, for lower OPEX.

My air cond installer quoted RM3.9k for *6unit air cond (conceal + installation job) for my house. Is the price reasonable?
*1unit is back to back and another 5unit involve conceal job w/ average 10-15feet per unit. He is using 0.71mm copper thickness, i saw ceo684
posted it before. So i assume the thickness is fine.
Much appreciated if someone can advise before confirming with the installer.
Not knowing how big ur units are
250-350 per unit give or take 1500-2100 for basic installation.
0.71mm copper is good, preferably acson/daikin pancake
Make sure IDU-ODU is 4-wire. The extra one for signal, use thin wire 1.5mm also nvm. 4 wire (LNE+signal) for safety. Thin wire dont cost much to add on, but its a PITA once u installed as u can't just add on easily.
Rest is hacking cost and concealment.

There are plenty details in the net regarding the 2 refrigerants, invertor and non. Take your time to read and undetstand b4 committing to a purchase.
To add ... if your usage is for long hours, buy an invertor, otherwise a non will do. So you have to decide which room unit is invertor and non. But if you have the budget, then go for all invertor.
Pana is ok .... others no comment.
Inverter for bigger units should save power.
Also depending on usage pattern. Keep at 25-27C very power saving. Running it like freezer 16C best inverter also useless for power saving.
