Hello,

I need to buy new AC for 190 sqft room top floor (sun directly hits the roof). So I know I need at least 2 Ton, but confusion is many people says that few brands 1.5 Ton AC's cooling is equivalent to 2 Ton in the other. So which brand I need and what tonnage?

A bit history on why I want new AC.
My first AC was 1.5 ton Voltas non inverter, It ran good the first year but cooling reduced from next year.
Many technicians have visited only to tell me that my AC is running perfectly. God knows what happened. But it won't chill the room as it used to do before and the compressor continues to run and room temp goes down but very slow. After so many diagnostics I came to a conclusion that because the unit was not vacuumed at install time, it's cooling efficiency was reduced but all technicians deny this fact. But I don't want to waste anymore time and money on this, I would rather buy new. My current AC already 5 years old now but this problem started happening since 2020, I bought it in 2019. In a nutshell I want to avoid this voltas brand all together.


Back to where we were, this post is about which brand's AC is must buy and what tonnage do I need 1.5 or 2 and it's cooling capacity, I want non inverter only.


Regards!

That is BS. Regardless of the length of the pipes, its necessary so that the refrigerant is not used in place of the vacuuming process thereby reducing the total quantity of the refrigerant which comes from the factory and hence reduced cooling.

Exactly. No compromise on vacuuming.

I was wondering if you could suggest the best place to install indoor unit. My room is 10x19, my last ac was installed on the 10 feet wall (marked as B in plan) as this seemed like the best place at that time and due to the limited length of the copper pipe that came with it, outdoor had to be placed directly facing the sun.

This time I'm thinking of placing the indoor unit on 19 feet wall (marked as c) between window and door which also happens to be the center of the wall. Another option is directly above the window. Which would be better place? In both of these places, outdoor unit will be in shade away from sunlight.

Last option is wall d but if I install there, copper pipes have to go sideways and will be shown, will require breaking the plastic piece on the side. If wall c is not good then I will be forced to install at d. What do you think?

Added a room plan for convenience.

Placing the ODU in shade is a good idea. It is going to get pretty hot when running and the heat from the sun will add to the existing heat, thus making it work more to cool thereby increasing the power consumption.

Have decided to place the IDU above window, this way it will be far from door, the pipes will just go straight out from behind and ODU should be inside shade and less hot area than before.

Either o general non inverter 1.5 ton or any other brand 2 ton.

If you guys have any last tips to share please do. I might buy today evening.
