The research activity is descriptive. The study analysis the customer satisfaction with the features of branded A/c in Coimbatore City with the reference of General A/C ETA General Private Ltd., Questionnaire DesignProper care has been taken to ensure that the information needs match the objectives, which in turn match the data collected through the questionnaire. The basic cardinal rules of Questionnaire design like using simple and clear words, the logical and sequential arrangement of questions has been taken care of. The questionnaire includes both open ended and closed ended questions with multiple choices; Open-ended questions enable wide range of responses. Close-ended questions offer a limited choice of response. Sampling DesignPopulationThe universe comprises people of Coimbatore City. Since the population of Coimbatore is large in number, researcher was unable to collect information from all individuals due to limitation of time. So part of the population is taken for analyzing and generating the findings, which is applicable for total market. Convenience Sampling Method:It is a population which is commonly referred to as a sample. It is obtained by selecting convenient population unit. It is suitable when the universe is not clearly defined.Sample unit is not clearComplete source list is not available Sampling Size:This refers to the number of item to be selected from the universe to constitute a sample. This is a major problem before a researcher. The single of sample should neither be excessively large nor to small. It should be optimum. A optimum sample is one which fulfills the requirements of efficiency, representatives, reliability and flexibility while deciding the size of the sample, researcher must determine the desired precision as also an acceptable confidence level for the estimate.The size of population variance needs to be considered as in case of larger variance usually a bigger sample is needed. The size of population must be kept in view for this also limit the sample size. The parameters of interest in a research study must be kept in view, while deciding the size of the sample. Costs to dictate the size of the sample that we can draw. As such budgetary constraints must invariably take in the consideration when we decide the sample size.212 respondents are sample size of the study. Sampling Unit:The set of customers where using A/C in Coimbatore. A decision has to be taken concerning or sampling unit before selecting sample. Sampling unit may be a geographical one such as state, district, village, etc., or a construction unit such as house, flat etc., or it may be a social unit such as family, club, school etc., or it may be an individual. The researcher will decide one or more of such units that has to select for his study. Period of StudyThe study was conducted during the period of 4 months from January -2016.

AnalysisAnalysis is the process of placing the data in an ordered form, combining them with the existing information and extracting the meaning from them. In other words, analysis is an answer to the question what message is conveyed by each group of data which are otherwise raw facts and are unable to give a meaningful information. The raw data become information only when they are analyzed and put in a meaningful form.Interpretation Interpretation is the process of relating various bits of information to other existing information. Interpretation attempts to answer, What relationship exists between the findings to the research objectives and hypothesis framed for the study in the beginning .To study the customer satisfaction towards branded A/C in Coimbatore city a survey was conducted and information was collected from 212 respondents. All the information collected with the help of questionnaire are tabulated and analyzed using data analysis tools like Simple percentage, chi-square test and weighted average method.

Tools used for AnalysisSimple Percentage AnalysisWeighted Average Method Simple Percentage Analysis Percentage refers to a special kind of ratio in making comparison between two or more data and to describe relationships. A simple percentage analysis was carried out for the major part of the data analysis. This is a univariate analysis where the percentage of a particular factor with different categories are calculated, in order to help one get their fair idea regarding the sample and thereby that of population. Without this percentage, the researcher would face difficulty in interpreting results.Statistical Analysis Weighted Average Method:When the relative importance of the various items is not the same, then we make use of weighted average method. Hence we multiply each item by a weight reflecting. The importance assigned to the item is the total and then divide them by the sum of weights.
