We are new to Angie’s but are experienced with anything insulation related! Home Shield Insulation is proud to bring the benefits of energy efficiency, comfort, and improved air quality to home owners in the Charlotte metro area.

"Poor communication around the amount of dust that the installation would leave or that we would need to remove any belongings from the attic or most importantly the adjoining closet where my wife stored her wedding dress. The install crew was also careless, leaving very noticeable scratches and dings on window and door frames. Management promised to address these repairs and dry clean the wedding dress but gave us the run around for months without addressing any of the issues caused by their crew. What’s arguably worse is we haven’t seen anything close to the amount of savings on energy bills that was promised in our first summer with our new insulation."

"We will never use this company again. They were not upfront on their labor charge for a part under warranty and then threatened us to send us to collections when we asked to meet them half way. They also tried selling us an air scrubber yet neglected to tell us the reason we are having a mold issue is because the seal between the house and the unit has holes in it. They also did not put back things moved to get to the unit and crawl space. It is unfortunate that there are companies out there who choose to do business in this manor."

Energy Efficiency Auditing questions, answered by experts

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

Costs depend on pipe length, accessibility, and whether additional services are required.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.
