Keep Heat Where It Belongs Year Round

Campbell Air Conditioning provides attic insulation installation and upgrades in Trussville and surrounding areas to reduce energy loss, stabilize indoor temperatures, and lower heating and cooling costs.

If your home in Trussville feels drafty in winter, stays hot during summer afternoons, or has utility bills that climb despite normal HVAC usage, the attic insulation may be insufficient or unevenly distributed. Attics without proper insulation allow heat to transfer directly through the ceiling, forcing your heating and cooling system to run longer to maintain comfort.

Campbell Air Conditioning installs blown-in fiberglass or cellulose insulation to achieve the recommended depth for this region, typically between 13 and 15 inches depending on the material used. The process involves air-sealing gaps around recessed lights, plumbing penetrations, and attic hatches before adding insulation, which prevents conditioned air from escaping into unconditioned spaces. You receive a more consistent indoor temperature, reduced strain on your HVAC equipment, and measurable savings on monthly energy bills.

How Attic Insulation Affects Your Home Comfort

When you schedule attic insulation service in Trussville, the technician measures the current insulation depth, inspects for moisture damage or compression, and identifies areas where insulation is missing or has settled. Air sealing is completed first, followed by blowing insulation evenly across the attic floor to the target depth.

After installation, you will notice that second-floor rooms stay cooler in summer and warmer in winter, your HVAC system cycles less frequently, and there are fewer drafts near ceilings. Properly installed insulation also reduces the risk of ice dams in winter by keeping the roof deck cold, preventing snow from melting unevenly and refreezing at the eaves.

This service does not include replacing roofing materials or repairing structural damage, but it does address insulation voids, compression from storage, and gaps around attic access points. Moisture barriers and vapor retarders may be recommended if condensation or mold is present during the inspection.

What Homeowners Ask About Attic Insulation

Homeowners in Trussville often ask how much insulation their attic needs, whether old insulation should be removed, and how long the installation takes.

What depth of attic insulation is recommended in Trussville?
Most homes in this climate should have insulation with an R-value between R-38 and R-49, which translates to 13 to 15 inches of blown-in fiberglass or cellulose. Your technician will measure current levels and recommend an upgrade if needed.
How does air sealing work before insulation is added?
Technicians use spray foam or caulk to seal gaps around wiring, plumbing, recessed lights, and the attic hatch. This prevents conditioned air from escaping into the attic and ensures insulation performs as intended.
When should old insulation be removed before adding new material?
If existing insulation is wet, moldy, compressed, or contaminated by pests, it should be removed before new insulation is installed. Dry, intact insulation can usually remain in place and be topped up to the recommended depth.
Why do some Trussville homes have uneven insulation coverage?
Insulation settles over time, especially in high-traffic areas of the attic or near vents. Homeowners who store items in the attic may also compress insulation, creating cold spots that allow heat transfer through the ceiling.
How quickly does attic insulation reduce energy bills?
You will see lower energy bills starting with the next full billing cycle, as your HVAC system no longer works as hard to maintain set temperatures. The reduction depends on how much insulation was missing and how extreme outdoor temperatures are during that period.
