Fort Pierce, FL
Smoke odor removal gets rid of the smell a fire leaves behind by removing its sources, not covering it. That means removing burned materials, cleaning soot and residue, cleaning or replacing HVAC components, sealing surfaces that cannot be fully cleaned, and then using deodorization methods such as thermal fogging or hydroxyl or ozone treatment where appropriate.

Overview
Smoke particles are tiny and travel into fabrics, insulation, wall cavities and ductwork. That is why a home can smell of smoke long after visible soot is gone, and why air fresheners and candles do not solve it.
Professionals work from the source outward: remove what is burned, clean what can be cleaned, seal what cannot, then deodorize the air and the remaining materials.
Some deodorization methods, such as ozone, require the space to be empty of people, pets and plants during treatment.
Warning signs
Smoke smell returning on humid days or when the AC runs
Odor in closets, drawers and upholstered furniture
Smell strongest near vents or returns
Odor after cleaning walls and floors
Smoke smell from a neighboring unit or attached garage

Straight answers
Without treatment it can last for months or longer, especially in fabrics and HVAC. With source removal and proper deodorization it can usually be eliminated.
Ozone can be effective in an unoccupied space, but it is a lung irritant. People, pets and plants must be out during treatment, as the EPA cautions.
A method that disperses a deodorizing agent as a fine heated fog so it reaches the same places smoke did.
Air purifiers with activated carbon can help with airborne odor but do not remove residue in materials, which is the main source.

Contents

Sealing and painting
Primer and repainting add materials and labor.
Common causes
Carpet, drapes, upholstery, insulation and unsealed wood absorb smoke.
Ducts and filters collect smoke particles and spread odor when the system runs.
Burned food creates a stubborn, pungent odor.
Wall cavities, attics and behind cabinets can hold smoke residue.
Safety first
The U.S. EPA warns that ozone at levels effective for odor treatment can harm health. Ozone treatment should only happen in an unoccupied space, with people, pets and plants out, and the space ventilated afterward as the provider directs.

On site
Odor is traced room by room, including HVAC, attic and wall cavities.
Burned materials are removed and remaining surfaces are cleaned of soot and residue.
Fort Pierce context
In Fort Pierce's humid climate, smoke odor can seem to come back on muggy days as moisture releases trapped odor from porous materials. Removing sources, not masking them, is what keeps it from returning.
Homes with interior air handler closets should have the system cleaned and the filter replaced after a fire.
