My wife had actually booked this job to happen while I was to be working from home. Plans changed and when I called ISO to rebook they were clear and helpful on the phone. They offered me a few other time slots and everything worked out. The job itself was done in the time they promised and unlike the company we had out a couple of years ago.. they explained what the heck they were doing. I am not going to get too excited about Duct Cleaning but the price seemed fair and the guys were clean and on time. Sure thats to be expected but as many of us know... it is not always the norm. I would call them back again no problem. On another note. The guys didn't leave a card or flyer behind.
