"Great service and a pleasure to work with. The whole process from the initial estimate through the installation of the additional insulation in our attic was easy and fast. Work was completed on time and on budget. They even completed the paperwork for rebates from our local power and gas companies, which knocked about half off the total cost. Would definitely recommend."

"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"

Insulation FAQs, answered by experts

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Through R-value assessments based on climate and existing insulation.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.
