It's a great company and I highly recommend them.
I hired Micro Clean to clean have my ducts and dryer vent cleaned, and I was right in hiring them as the company is extremely professional and nice. I have been amazed by their customer service.
The quality of the work seemed good. They took before and after pictures of my vents and there is certainly a huge difference! They also did a great job of cleaning up afterwards and inspecting all of the places that they did work to make sure everything was clean and orderly. It's a great company and I highly recommend them.
