"This company is absolutely amazing I have yet to meet somebody that makes mostly all of their materials from their own sawmill and can make doors, trim shelves, custom encasements, and just about anything vanitys countertops, fencing framing it’s absolutely amazing. Their work speaks for itself and I give them five stars all day and the amount of money they saved me on my remodel was 50% less than any other contractor out of the seven we had estimates from"

"I had an Absolutely Fantastic Experience!! My husband & I were so lucky to have gotten Jason Scharf to come out to our home, he was very insightful, helpful, courteous and very professional. Jason explained step-by-step what he was doing along the way & what would work best within our home with 4 different price ranges that would work for us. Jason was very informative. He mentioned and advised me on some items that would require attention on a monthly basis which I was grateful for. Upon completion, he reviewed the bill and explained any questions that I had. I was very pleased. Overall, Jason’s work was outstanding. I would recommend Jason from Astar to anyone I know that is in need of a central air system in their home. He was one of the kindest, funny and coolest Design Specialists by far. Thanks again Jason you're the Best! We can't wait for everything to be completed."

"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

Insulation FAQs, answered by experts

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.
