"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.
