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."

Since 2012, Air Tech has offered quality services with professional attention that our clients deserve. Contact us to know more about Air conditioning repair service.

"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

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.
