"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

Insulation questions, answered by experts

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

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.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.
