First let me say I don't write reviews in general. It's just not something I do but this company is truly amazing and they really deserve more than just a good review. They went so far above and beyond what was required of them in the contract to make sure that I was happy with everything and I couldn't be more pleased with their work. They were extremely professional but also extremely friendly. After the original installation there were a few issues and they came back immediately to fix them. In fact when I called and left a message late Saturday afternoon when they were closed, "Little Mike" called me back within 5 minutes offering to come over immediately to try and diagnose the problem although I know he was home with his family at the time. They also did work that was not covered in the contract and I was not charged one cent extra. I'm sure they lost money on my job but they never made me feel like I was a burden or that I was being difficult to please. They spent about a day and a half extra after the original installation making sure the job was done right including replacing and upgrading the brand new unit they had just installed. Not once during that time did they act annoyed or frustrated, you could genuinely tell the only thing they wanted in the end was a happy customer. Once all the work was finished they checked back with me several times to make sure that everything was working properly and that I was satisfied. You just can't find companies that run their businesses like this anymore. I know if it had been any other a/c company I would have been charged an arm and a leg for all the extra work they did, if I could get them to come back at all. This company has had a great reputation for a long time and now I know why. A huge thanks to "Little Mike" and the wonderful crew at Clean Air Systems, they truly are one of a kind business.
