"I scheduled a tune-up service for my AC for 9-12 o'clock. At 11:35, I called to see if they were still coming, and she tells me 'sorry, the tech is running behind. He will be there closer to 1:00'. I accepted that, then waited until after 1:00 to call them again, only to find out the tech was still an hour away, working on another job. I thought the whole point of a service 'window' was to provide flexibility for the tech in case they get held up. I had to leave my house by 2:30, so I canceled the appointment. I took out an entire day for absolutely nothing."

"It was an excellent experience! My old Kenmore fridge (probably from the 90s) quit cooling/defrosting. After looking to replace it and finding thanks to the pandemic refrigerators are on backorder for months, I called 3 appliance repair companies who didn't call me back. I found Neli and was able to set up an appointment at a time I picked.. An incredibly patient tech (Chris C.) came chat on at the appointed time. I waited about 5 mins as he was wrapping up another call. I walked me through the diagnosis using a virtual support app on my phone. He was able to help me with taking things apart, helped me use our multimeter, and diagnosed the problem. I can do this repair myself. He gave me the exact part numbers and told me what I need to do. All for $35 for an hour on a Sunday. I can't believe how great this was. I thought I had to replace my refrigerator, but for $35 + $111 in parts (I could have gone cheaper but chose OEM) my refrigerator will return to health. Their website lists the tools you will need for a diagnosis/repair, make sure you have them ready. For refrigerators, you need a screwdriver (flat & phillips), a socket set, a multimeter, and theoretically a pair of pliers but I didn't use them. Also make sure your phone is charged (lesson learned)."
