| ![]() There is a thin capillary tube, just before the cooling coils on the indoor unit. If you see frosting there, then the gas topping is required. In your case since this is already done, the mechanic should be looking at the pressures before and after the compressor, maybe the compressor is leaking at the valves. |

| ![]() Which model(s) of Daikin Split Inverter do you have ? Looking at the 2014 model range was wondering if the FTKE25/35 Or FTKD50/60/71F would be better ? These models use the R22 refrigerant but considerably cheaper than the R410A and R32 models. The R32 models aren't available with most dealers here in Bangalore and they expect to receive stock in about 2 weeks. |

Previously I had a 13 year old Hitachi Window A/c which conked off last year. We have started using the new A/c only from March 15th this year. I will have to wait until April 15th to know the extra cost for power in running this a/c. My usage is 8~10 hours per day. The a/c has been performing quote good so far. The major difference I noticed is the remarkable improvement in the uniformity of cooling and temperature maintained with the inverter a/c which gives undisturbed sleep compared to the window a/c. Noise is another factor. All the best in your hunt for the suitable a/c. Daikin_Ac_Quotation.doc | |

3. I used to do this. If you have a pedestal fan, keep the bedroom door open, with the pedestal fan at the door, to further propel cool air towards the living room. That way the living room does get cooled without needed to get the bedroom freezing cold. The dissipation via the passage depends on how much air flow is present . | |

As you said, it is always better to buy it from an AC accessory shop rather than from the company. I got 3m copper cables each of the two sizes which came with thick insulating material for the entire length. Cost me close to 2600/-. The guy said that the copper is imported from Malaysia and is of the best quality. Took it with a pinch of salt. | |

Most air conditioning companies in India import the indoor units, usually contract manufactured by some Chinese company cause they mass produce and hence cheaper to build. Midea is one company that comes to mind. | |

India produces very little copper, hence most of it is imported. For most of the tubing it is either Malaysia or China. Good copper tubing is ductile and reasonably soft. Bad tubing is brittle and slightly whitish tinge. When you cut it, the edges will be a bit ragged. | |

An iitb person claims that white cement, dolomite powder and nano acrylate lasts long and is cheap, any idea where to source dolomite powder? And if tiles, wouldn't vitrified be a better option as water absorption would be low. | |

| ![]() I bought a Daikin 1.8T R32 series Inverter AC model FTKV60NRV16. Paid 53.7K. Thank you all for your valuable inputs and guidance. Today, the guys came for installation and there is a problem. During the construction of the house, the builders made a provision for installation of the AC. The wall on which the AC is an internal wall. So, they have provided a 3" concealed PVC pipe on the wall which is brought out on the external wall. Due to some obstacles, this PVC pipe has one elbow joint on each end. The AC installation guys say it is not possible to pull the copper pipe through the two elbow joints as the copper pipe is very thick. The copper pipe has a dimension of about 3/4" outer diameter and is quite strong (they are charging me Rs.350/ft. for this tube). It would definitely not be possible to pull this tube through the elbow joints. The only option left to me now is to move the AC to the external wall and punch a hole. The trouble with this approach is that this wall is covered with the sloping tiles and I have to break the tiles and the concrete to do this. I would like to explore all other possibilities before doing this. I have a few questions: 1. Is there any other flexible copper pipe that can be routed through a bent PVC pipe? 2. Does any other member here have an AC mounted on an inner wall and had to route the copper pipe to an external wall? How did you manage this? 3. What is the nominal price of copper pipe? As this is my first AC I am not sure if Rs.350/ft is the right price. The quality of the pipe looks very good though. Thank you in advance for all the guidance.

| ![]() Thanks for the reply, Turbanator. I dont have a false ceiling, so that option is ruled out as well. I also got a second opinion from another AC installer and he also confirmed it is not possible to take the copper tube through the bent pipe. So it has to be the harder way :( |

| ![]() I have not used but white glazed ceramic tiles are considered the best. The glossy finish reflects most of the heat. You do not have to buy new tiles. If you have access to used / broken tiles, its economical and achieves its objective. |
