If one part of the house is always hotter than the thermostat says, the attic is usually the reason.
The exact scope depends on your home and what the inspection finds.
Every project begins with a free professional inspection. The final scope depends on the home, existing system, and requirements.

Why the ceiling, not the windows, is where a Hill Country home loses the fight in August. What 14 inches of blown-in insulation means, when topping up works and when the old material has to come out.

An AC that never shuts off in a Texas summer is usually not broken. Attic ducts, a dirty coil, a thin attic and a leaking plenum are the common causes, and most are cheaper to fix than a new unit.

Not always. If it is clean, dry and simply thin we can top it up. If it has been wet, contaminated, or compressed below the joists, adding on top just seals the problem in.
That is the depth that brings a Central Texas attic to the recommended R-value with blown-in material. We leave depth markers so you can check it yourself.
No — we install blown-in insulation only. If spray foam is genuinely better for your house, we will tell you.
Most homes out here are a single day. Larger attics or difficult access can run into a second day, and that is in the estimate.
It depends on attic square footage, existing depth and access. We measure, then leave a written estimate. Free to have us out.
Start with a free professional inspection. We look, photograph, and put the price in writing before any work.
