Fault Sensing In Air Conditioners

  • Radhika, Ankita, Priya Chaturvedi, Surabhi Singh
  • To develop a mechanism that automatically senses the fault (issue) in
    air conditioners and reports to the user about the same (this can  be used to detect fault in other appliances also, which are programmed
    in some or other way), and also fetches from the manufacturing
    company right way to approach the problem, and cost that will be
    incurred.

  • AC Users, Individuals as well as organizations where ACs have been installed.

  • Interviewee 1

    Q1. Do you have an AC?

    Ans. Yes.

    Q2. Have you ever faced any problem with it? If yes, what was it?

    Ans. Yes. It stopped cooling abruptly.

    Q3. How do you know this was the exact issue with your AC?

    Ans. Private mechanic told us.

    Q4. Why didn't you call the customer care?

    Ans. We called them. But they didn't respond. Also, we thought it would take the electrician (that offered by the company) time to reach and also they take long to repair and install back the AC. So we just called the electrician from a nearby shop. This was the first time. Then onwards after a year or so it's cooling keeps on decreasing so we have to take for servicing after every nine-ten months.

    Q5. How much did you spend on this solution?

    Ans. I don't remember the price. He was my father's friend so we got a little discount but I don't remember how much did we pay him.

    Q6. Did you compare this price rate with that offered by other electricians?

    Ans. No. Since he was a family friend we thought the price was all right.

    Interview 2

    Q1. Do you have an AC?

    Ans. No, we don't have it in our house but we have it in our college.

    Q2. Have you ever faced any problem with it? If yes, what was it?

    Ans. Yes. One day it almost stopped working. So basically it wasn't cooling anymore.

    Q3. What did you do to solve it?

    Ans. We called a local electrician. 

    Q4. Why didn't you call customer care?

    Ans. It would have taken time. 

    Q5. How much was the cost of repair?

    Ans. Around 4500. He said as he had to change many things so the cost was high.

    Q6. After that the problem was solved?

    Ans. Yes. It started working now. But the cooling was not as good as before.

    Q7. Did you compare the price rates with that offered by other electricians?

    Ans. No. I mean we would have but since we didn't know the exact problem so it was foolish to compare price rates.

  • Miss X and Mr. Z, together bought two air conditioners from Y company. After working well for two years, Miss X's air conditioner started to make weird noises and stopped functioning abruptly. Miss  X, who did not have much experience in handling air conditioner problems kept calm for 2-3 days and then ended up searching Google for the probable issue and the causes. This was not of much help so she decided to call an electrician to fix the issue. The electrician told her that there was some problem with the grills and asked for 5000 bucks to fix it. 

    A week later Miss X's colleague, Mr. Z told her that he faced the same problem and on calling a technician from the Y company to fix the issue, he ended up paying only 3000 bucks. This, of course, disheartened Miss X.

    Sitting at the adjacent desk, was Miss B who overheard what the two were talking about. She jumped in and asked them why they were still not using this new 'gadget' (maybe technology, don't know what to call it) which helps its users to
    identify the exact issue in electrical appliances and also supplies them with the steps to fix the issue and the cost that will be incurred in case an experienced person (technician/electrician) is required.Q
