Countywide Mechanical (CM) charged me well over $500 to repair my shower head's weak pressure issue. At the time, I was renting my condo unit to tenants, and paid the fee. Less than 2 month's later, the issue reoccured. I drove down from LA to examine the issue for myself. It simply had calciu buildup on the shower head. I went to Home Depot and paid $20 for a new shower head and installed it myself - issue fully resolved.

I called CM several times to complain and they gave me "run around", always passing my call to some worthless supervisor who would never return my call. This is such an unethical way to conduct business! CM was recommended to me by my building's HOA. I informed my HOA of my unpleasant experience, and I haven't seen any CM van's around for a while. I'm going to make sure my story/experience spreads.

Oh yeah, what goes around comes around. It goes without say, I would have given CM a negative rating if I could. Update: my HOA had other issues with CM and does not use their services anymore. I'm happy they saw the light!

I had a great experience with Countywide. I call to schedule on Thursday afternoon and they arrived the next day for an appointment at noon. I needed a couple shower valves replaced, and the technician, Ruben, was super friendly and had the process done in no time flat. They provided great, timely service at a very reasonable price, and I'm glad I know I can rely on them in the future. Stoked!

Critical: Professionalism A driver from County Mechanical cut me off on the freeway as we were merging. He then honked his horn and gave me a look like I was in the wrong. Clearly he wasn't paying attention to where he was going. I would not use a company that has employees with that kind of attitude.

The a/c technician that came to do the repair was awesome! He was professional and very knowledgeable in his trade. I believe his name was Terrance. He explained everything and answered all my questions and concerns. Great customer service!

Critical: Professionalism Driver 251 of a Chevy Pick up doesn't merge properly, cuts people off, and was going 15 over in a school zone. All this happened in a matter of minutes I can only imagine what he's driving like the rest of the day.
