First the good news. Atiar was able to come by to our house just a couple of hours after I called him--very prompt service. Also, his charges are very reasonable.
Now the bad news. Our 20 year-old refrigerator was having some problems: 1. the ice-maker was working very sporadically, and 2) the temperature in the main part of fridge seemed to be higher than normal (I had bought a cheap $3 thermometer from Home Depot and it was reading about 46 degrees Fahrenheit, much higher than the recommended levels of 35-37 F. Atiar discounted the reading from my cheap thermometer; and said the temperature in the main part of the fridge was normal--and his method for determining that was to briefly touch items in the fridge with his hand!
His diagnosis was that a new ice maker was needed and so I agreed that he should order that part (it would take 4-5 days to arrive). Between the time of his first visit and the arrival of the part I borrowed a better thermometer from my neighbor and I also purchased a special Taylor refrigerator thermometer from Amazon (they are very cheap, by the way). All three thermometers now read the same thing--the temperature in the main part of the fridge was now at 50 F--much too high.
So, I no longer trusted Atiar's diagnosis. I had also decided that it was time to buy a new fridge. So I called him. The new ice-maker had arrived, and I told him that I no longer wanted it as I was buying a new fridge. I offered to reimburse him for the time he had spent ordering the part, and any expense associated with returning the part, but he declined. Like I said above, his charges are very reasonable!
However, I do believe that Atiar mis-diagnosed the problem with my fridge. Hence the poor rating. Looking at all of the other reviews, he does appear to know his stuff and provide very good service. But not this time.
