The evidence — in reviewers' own words
Critical
“I needed my compressor replaced in my three door cooler. After one of the service guys came by to check out the job, he quoted me $1100 over the phone to replace the compressor. He did a good job, everything worked. When he wrote the bill, he added another $95.00 for a "diagnostic" fee. I'm a firm believer in doing what you say. If you say $1100, that's what i'll pay. The service guy and his partner were very, …”
“I rarely leave reviews. I do not know, how everyone else had 5 star left reviews. Two technician came on 8/8/2023. They came in my store 1:29PM and They found out what was problem 2:08pm(tooks 39min). They go back to my parking lot 2:10pm and they left 3:03pm. When they check my cooler, They did not know what was the problem first. They called someone to check the problems. The other technician is not technician. He …”
“A scam of a company. I would not recommend it to anyone. Charged me an insane amount and didn't even fix the issue, due to insufficient diagnostics being performed and "assuming it would fix it," leading to additional "trip charges" to properly diagnose it, and then trying to charge over $4k on top of that to fix it. No care that the tech didn't previously diagnose the problem correctly, leading to incorrect charges …”
Positive
“Brandon did electrical work for us. He was knowledgeable, courteous, and professional, and did good work.”
“JD is awesome! He cleaned up nicer than it was before he got here and he gave lots of good advice, and was very pleasant to work with. I even had to stop him from doing our dirty dishes lol. They were able to come within 2 hrs of our HOA maintenance guy calling them and got the drain cleared in under an hour.”
