Horrible job - do not use
I received a Groupon as a gift for vent cleaning. The tech showed up 2 1/2 hours after calling to say he was on his way. He showed up in a beat up van with no company markings. He kept trying to upsell me, even though I refused every time and told him I would not be giving him any additional money today. 10 minutes after he started, another woman walked into my house, with no invitation and no introduction, and acted as his "assistant" although she clearly had no idea what she was doing. They made a mess, got dust everywhere, and required me to cover up my furniture with my own sheets. I had asked if any preparations needed to be made before they arrived, and was told no when I scheduled the appointment. They never used any type of vacuum on any of the vents. He didn't even bring a ladder. Instead, I later discovered that he was standing on one of my dining room chairs to reach a ceiling vent. Horrible, unprofessional service.
