Hi. I work for a company that specializes in HVAC, plumbing, and electrical. The duct cleaning department is only about 4 years old and is only 2 trucks and 3 people including myself. We have Hypervac H1 trucks. My question is, for those of you with duct cleaning businesses or experience, is duct cleaning an individual job or a team job? I’ve been asking for some help for quite a while now and have been denied so I was just wondering what others are doing.
