""If you’re shopping around for insulation, save yourself the time and call Geo-Insulation. As a military retiree, I truly value honesty and professional execution, and Tom (owner) and his team delivered on both. After comparing four different quotes, it was clear that Geo-Insulation was the best choice. I told Tom I was looking for a reasonable ROI, and he was incredibly upfront about which upgrades would yield the most savings. His pricing was fair and transparent—unlike several competitors I contacted. The installation was fast, clean, and professional. If you want an honest local business with no-pressure sales and expert work, look no further than Geo-Insulation!""

"They recommended that I did not need roof insulation. Very honest and professional opinion and advised if they performed the insulation (since he determined my insulation was very good), I would not realize any benefit. I really appreciated that honest evaluation. Would recommend them to anyone needing insulation; they are not a fly by night firm and in explaining what they do and how they do it, separate themselves from the rest of the pack."

"AHC kept me informed of when the work would be done. Weather caused some delays in getting to my project, which I fully understand. AHC kept in touch with me giving me updates and I greatly appreciated that they did so. AHC s spray work was done very well. There was no mess or over spray to clean up. I did the required prep work such as filling in places where the insulation spray could escape. Also, it is important for you to cover areas that you do not want the spray to cover. AHC did a great job follwing the plan. I am very happy with their work and would definitely recommend them."

"Excellent attention to detail. Also does A/C install and repair work. Will have them do all of my preventative maintenance, as well as install insulation over my garage ceiling."
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.
