"Chris with Tyson Energy Solutions provided very thorough estimate after a close look at my 1940's home in Fresno. He is very knowledge about insulation & attic/gable fans in providing greatest energy efficiency during both hot summer months & cold winters. The work was done on time at a very reasonable cost, including attic insulation & a very good attic fan. The cooler temperature of the home was distinct right away; the noise while running the cooler on roof is much quieter. The attic fan & insulation together make a very distinct improvement. I would recommend Tyson Energy Solutions without any hesitation."

"I'm extremely impressed with Luis and Icon Insulation. After moving into a 115 year old house about 5 months ago, and having a lot of contractors doing various jobs, Luis was a breath of fresh air! I had him Insulate my attic, and then I had him back again to insulate under our floor. I would highly recommend Icon Insulation to anyone I know. They are very responsive and answered all my questions before our appointment, punctual, professional, and have a great work ethic. (Something hard to find these days.) Thank you for your great work!"

"I was impressed with Aaron, the owner. He thoroughly explained what he was going to do, and took before and after photos of the job. I have noticed a big difference in the comfort level of my home. The HVAC unit rarely kicks on, as the insulation is holding the temp much better."

"Fantastically well! I would highly recommend America One Insulation to anyone requiring insulation removal and installation. Their team worked non-stop to remove all the old insulation in our attic; putting in a 12 hour day. David, the owner of America One Insulation, followed up prior to the team arriving (a father and son) during the removal process, as well as that evening. One could not ask for a more professional company to do business with."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."


Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
