An example of an negative review: Hired these guys to replace condenser fan motor on roof top ac unit in July 2011. The technician just happened to have the correct replacement on the truck, installed it, and ac unit worked. $400. So I use ac all summer. Next summer rolls around, and the motor is wobbling and sometimes wont run. I decide I will replace the motor myself, and I found a do it youreself supplier here in vegas called appliance parts center. The parts guys had to call the mfr, and get the exact correct part. The bad part was apparently the incorrect rpm rating, causing it to fail so soon. I learned that commercial cooling and heating had installed the wrong motor. They also should have replaced the fan blade, but did not. I learned a new condenser motor should last at least 5 years, and usualy when replaced, the fan blade should be replaced as well, to ensure a warped fan blade does not cause premature motor failure. I also learned that they had over charged me for the motor. I got the correct new motor and fan blade for a total of $230, and installed it myself. The motor was $150. commercial cooling and heating is a complete price gouging rip off operation. On top of that they dont even install the correct parts and do not care. I did a bit of research and the nevada state contractors board shows they have a history of not paying their suppliers, and home owners getting liems put on their homes. Might want to avoid these clowns.

An example of an positive review: I'm not sure if they are new owners or if the other reviews are just off or what but I had an incredible experience. I bought my scooter used from AZ Scooter (also very nice folks), but got it serviced here at Performance Scooter (they are a few blocks from my house). They gave it the once over, replaced a valve stem, tweaked the engine a tad, and tightened up a few things like the mirrors and were extremely nice and pleasant about the whole thing. I think maybe folks have some unrealistic expectations when they buy a cheap scooter, and that may be at the heart of the other reviews. Had I known these guys were just down the street I would have bought from them. Knowing my very used (but well loved) scooter will need replacing in the next year I am definitely planning on buying from them. They were super nice and honest about my scooter and it's condition. For what it's worth, they gave the same assessment as the dealer I bought it from so unless they are all in cahoots I think these guys are pretty honest.

An example of an negative review: Pretty disappointed. I was excited to try this place out for a late dinner, after reading all the previous reviews; just wanted to go and place a to-go order. Arrived at 9:35pm, and they told us the kitchen was closed. Most restaurants have to serve until their closing time (which was 10pm). Maybe it's just Chinese places that stop serving? I'm not sure. But I'm not used to walking into a place BEFORE they close and being sent away. They lost my business for good. I know I should have called beforehand. I normally wouldn't go to a restaurant that close to closing time, but when I do, they at least take my money!
