One of my most hated tasks in this business is insulating duct work. I know that it is a necessity for some applications and obviously, more work means a bigger invoice. However, it is one of the most tedious of the jobs that I have and can eat up hours quickly, leaving me little time for other work. I know that it comes with the territory though and for the first time this year I have a full day of pinning and insulating. Any business is good business.
