2. Frosting is the initial stage. If there is sufficient moisture in the air, then the ice slow builds up. 3. The gas leaks mostly from the filling point, and then from the joints. As the air expands to produce the cooling in the Indoor Unit, that is where ice starts forming, and not at the leakage point (unless the pipe in the front condenser is punctured) Again, first check if there is sufficient air flow (bad blower, clogged filters or choked passages). If it is fine, only then suspect gas leakage. One point alluded to in one of the previous posts is that if there is moisture in the gas, then an ice crystal can choke the gas passage. That happens either due to moist gas when filled , or a leakage. As there is a moisture trap (desiccant) in the gas circuit, first the desiccant has to be used up, and then the ice crystals form and choke the gas line. A sure way to confirm it is to switch the AC off for half an hour. On switching the AC the cooling will be perfect till the crystal form and the gas stops circulating. In your case there is cooling and ice formation, so you can rule moisture in gas out. | |

The ice formation patten definitely points to a gas leak, but clean the parts and then check. | |

Senior - BHPian ![]() | ![]() Hi Folks please provide me some valuable suggestion on buying an a/c for my room (specs attached). I am looking for a 1.5 t split a/c below 35k. I have shortlisted the following ones - LG - LSA5AR3T - 32k - 3 star Hitachi - RAU5186SDD - 35 - 5 star Last edited by girishglg : 15th April 2012 at 15:30. |

It does not come with the 4m piping. See the brochure of website. It's for people who already have piping from a previous split. It's a good Ac though. Hitachi is better than LG by miles. You should keep this in mind too. | |

Would a leaking gas leave such a uniform pattern of ice? I thought it would be more like a spot-cooling with ices forming more like an irregular blob rather than a perfectly laid strip of ice. | |

| ![]() Formation of ice at the evaporator unit is because of blocked air or low freon pressure. Two things to check 1. Functioning of fan motor - coil, capacitor; One of them should be weak requires a repair/replacement. 2. Low freon gas pressure in the compressor. Check if the gas pressure at the suction side (low side input) reads somewhere between 70-75 psi. Anything lesser would need a recharge. If you have a clamp-on meter, you could check the current drawn when the compressor switches itself on. For a 1.5 ton unit, the reading should be around 11A when the unit starts and should slowly come down between 8.5-9A. |

Some key statistics - Room Size - 140 sq ft Window direction - East Floor - Top floor Usage - 8 hours mostly night times most of the year Also since it is the first time purchase of an ac please educate on -

Senior - BHPian ![]() | ![]() Bought a Panasonic 1.5 Ton 3 Star AC on Friday and got it fixed on Saturday, the cooling is very good and absolutely silent. Cost me 29K excluding fixing charges. Here is the model number CU-YC18NKY-1. One thing that is bothering me is, my earlier older window AC had a mode called Sleep mode (or night mode) in which it used to switch off the compressor after sometime when running at night, making the temperature not too cold. It also probably meant low electricity consumption. This feature is missing on this AC. Any idea why? or should i have gone with the 5 Star rating one? At the moment we are manually switching off, or setting a timer to switch it off. |

| ![]() You could set the thermostat or use an off-timer and have a table/floor/ceiling fan running all night. An alternative would be to have a high-end generic remote control that can be programmed to automatically send a signal to the AC. Off the top of my head, I can think of the Sony universal remote controls. I know for certain that the Logitech Harmony series of universal remote controls don't have a timer so you would want to cross that off your list. |

| ![]() Was looking for an AC to purchase under EMI. Was very happy with the Reliance Digital offer of 15 EMI (5* only) and a new outlet opened in Sahakarnagar which would have made life easy. However the did not have stock for Samsung 5*. I ended up going to Mantri Mall and visiting the Samsung Shop. They have an 18/4 option from Future Capital. They did not have stock of the new 3*, so got an offer for AS183BGC at Rs30150/- (installation extra rs2500/-) This is last years model, mar 2011, so the 3* is actualy a 2* Got it installed yesterday, inital impression very cool ![]() Unfortunately i have noticed there is water dropplets appearing near the power swtich/display. The AC does not seem to be installed very straight, sligt slope. Not sure if that is the cause. Any ideas, we have called the installers to check. so let see what he has to say. |

Team-BHP Support ![]() ![]() | ![]() Guys, planning to install an ac in our rented apartment in Chennai. I'm a complete newbie when it comes to ac. Never needed it back in Kerala, but Chennai is a different story. Hence, totally confused after going through this thread. Requirement is for a normal sized bedroom, on the top floor. (Hence you can imagine the heat in Chennai summer!). Will a 1T ac suffice? Or do i need to go for something bigger? Which is the reliable brand at prices less than 30k? I'll prefer it to use as less electricity as possible. 1T, 5* split ac will be a good choice? As mentioned - priorities are reliability & low power consumption. |
