Air Quality Services and Mold Remediation
Ductwork, air handlers, evaporator coils, blowers, drain pans, and especially the ceiling plenums where coastal humidity lets mold take hold. PrOzone treats the entire HVAC system with EPA-approved antimicrobials and ozone shock treatment, with before-and-after documentation — for homes and businesses across Los Cabos and Todos Santos.
Brushing and vacuuming a duct pulls out loose debris, but it leaves behind the mold spores and bacterial film living on coils, drain pans, and plenum liners. We follow mechanical cleaning with EPA-approved antimicrobial application and ozone shock treatment so the system is actually sanitized.
Most homes and offices here use the ceiling cavity as a return plenum. That space is warm, humid, dusty, and never inspected — which makes it the single most common place we find active mold growth feeding the entire building's air.
Whatever grows inside the equipment is pushed into every room each time the A/C runs. Treating the air handler, coils, and plenums is the difference between fixing the source and re-treating symptoms every season.
Dust settling on surfaces again within days of cleaning
A musty or sour smell in the first minutes after the A/C starts
Allergies, congestion, or headaches that improve when you leave the property
Weak airflow, uneven cooling, or rooms that never reach temperature
Rising electricity bills from a system working harder than it should
Before
AfterReal results from residential and commercial air conditioning systems in Los Cabos. Every job is documented with before-and-after photos.
Full supply and return runs mechanically cleaned, then treated with EPA-approved antimicrobials — flex duct, rigid duct, and lined trunks.
Our specialty. We open, inspect, clean, and disinfect the ceiling plenum spaces where humidity and dust let mold establish unnoticed.
Evaporator coils, blower wheels, housings, and drain pans cleaned and sanitized — the components that stay wet and feed growth.
After disinfection we run a controlled ozone shock through the system and the space to neutralize residual spores and odors.
Air or surface samples analyzed through our alliance with Hayes Microbial when you need documented proof of the result.

"Jose has helped us with mold issues on and off for years. Living right on the beach makes your property more vulnerable. He used an ozone machine to purify the air, which worked very well, and also deep cleaned our 4 mini-splits as general maintenance. He also installed a dehumidifier that makes a big difference in humid season. He is honest, reliable, and very knowledgeable at his craft."
