Pissedconsumer.com asked that I write an update. Armtech never offered a refund, discount, apology, nor explanation.
On the bright side, I got both of my appliances repaired for ~$800, as opposed to replacing both of them as recommended by Armtech at a cost of $5000+.
Repairs took a total of 2 hours. My advice is to skip my first step and call someone else.

I needed refrigerator and dishwasher service. I found Armtech on Thumbtack. The first warning sign that I ignored was the fact that he circumvented the app's messaging system and contacted me directly. My fault for listing my cell - but it's noteworthy that he cheated his own business partner (Thumbtack) to save the referral fee. Mr. Massaba made an appointment for 9:00am. He arrived at 1:30pm. He worked on my refrigerator for an hour or so, then called me into the kitchen to help him. He could not disassemble the thing to access the compressor. Then, he could not get it reassembled correctly. This was the second sign I ignored. I should have sent him away immediately. Once the refrigerator was reassembled (with my help), he told me it was totaled, that I should just buy a new one. This is a 2 year old Samsung smart refrigerator, about $5000. According to Mr. Massaba, the many parts needed to fix it would cost more than a new one. The only problem he was intended to fix? One of two refrigerator sections was only cooling to 36 degrees, as opposed to the other section which maintains 33 degrees. The freezer section was running like a champ. Third warning sign and I ignored it. So...on to the dishwasher. I melted a Tupperware lid on the heating element. It only needed a new heating element. It still washed dishes great, it just wouldn't dry them. I told this to Mr. Massaba before setting the appointment, gave him the model number, and asked that he bring the part. He did not. Instead, he told me via email later that evening: "The Heating Element is NO LONGER AVAILABLE, just buy a new dishwasher I will do installation for you." (his caps) It's a stainless Kenmore dishwasher, about 4 years old. I don't know how much a new one costs, because another technician came out and replaced the heating element in mine the next day. In short, Mr. Massaba does not know what he's doing. That's giving him the benefit of the doubt, because the only other option is that he's a crook. He likely makes a pretty good living from his "diagnosis fees" alone and probably installs a few appliances that people may not need. If you ignore these warning signs like I did, it'll cost you.
