I've gut renovated four houses and these guys are by far the worst plumbers, and the worst…read moresubcontractors, I've ever encountered. For example, they installed a free-standing tub backwards with the drain exposed to the room, installed a sink that was smashed on one side close to a wall (apparently hoping we would not notice the damaged they caused), and forgot to include parts on three Duravit in-wall toilets that have caused constant leaks. I'm sure there are more plumbing problems in our house that haven't been revealed yet. Our GC (who was awesome) fired them in the middle of the job and replaced them with StraightEdge Plumbing. The StraightEdge team is everything CZ is not - professional, reliable, and knowledgeable.

These guys are absolutely the worst company I have ever dealt with. We only used them because the…read moreprevious homeowner used them and I thought it would be easier. They do not care one bit about their customers. The whole staff is so nervous to give you any information on when they can get you scheduled or where a part is or when it's going to show up. The entire organization is programmed to evade responsibility it is always someone else in the organization who could possibly answer your question, and they are not available but would call you back. Never happened. I needed a part for my A/C it took 6 days for them to place the order .... I had the exact same part number on Amazon could have had the part in two days, but I didn't want to void any warranties. In hindsight it would have been much smarter than living without A/C in July for two weeks. Never again with these guys. Total run around!!! Please use someone else if you can. Trust me on this. I never write reviews, but this feels like a completely coached organization. They would have gotten zero stars if it was possible. Their overall score is a lot higher than it should be because people have to give them at least 1 star.

When I asked for ballpark, they said sounds like your 15 your-old system is too old to fix (coolant is no longer being used, so hard to re-charge system, etc. etc.), so could be $12-15k to replace. That's when I cold-called Action Air, just based on favorable Yelp rating and long time (9+) years in business. The woman I spoke to said they'd be there LATER THAT SAME DAY (Fri) and would keep me posted when he was in the nabe. I got a text at 4 pm saying tech on his way. David showed up within minutes. He was courteous, knowledgeable, efficient ... and honest. Made a quick circuit of our equipment (compressor, air handler, thermostat), and promptly determined it was just a thermostat issue. He went out to his truck and replaced the thermostat, explaining how it worked and giving us the user's manual from the box it came in. While there, he checked our air filters and the compressor, took a couple readings at the compressor and told us everything looked great, and that we should just hose out the grill around the outdoor compressor fan, noting that it was located close to a dryer vent so needed extra attention. Bottom line: This is just what. you want and need in a repair company, particularly when you're talking about equipment you may know very little about so could be at the mercy of dishonest vendors. Can't recommend Action (and David) highly enough. Saved me possibly thousands of $$$.
