Q: Should ductwork be wrapped in insulation?

Upgrade Remodeling did a fair job at a fair price and did it quickly. However, I did not get the plumbing fixtures agreed upon nor did I receive the type if glass enclosure agreed upon. There was also no post installation follow-up. Overall, I would cautiuosly recommend this company.
