They arrived on time as promised but that's where the good service ended. The technician overcounted the number of registers, which he corrected after I challenged him, and when he was cleaning the ducts, much of the dirt from the ducts ended up in the living space all over the furniture and floor. He used a useless vacuum to sweep up some of the debris but there is still dust and dirt everywhere. I would have thought they would have a shroud for the registers to contain the dirt.

I would never recommend them to anyone.
