Throughout the world, climate and lifestyle changes have resulted in a shift from outdoor environments to airtight and energy-efficient environments at home and in workplaces, where people spend a substantial part of their time. In these environments, inadequate maintenance of air conditioners, poor building or home design, and the activities of its occupants can lead to poor health conditions, which may include respiratory diseases. Under a descriptive, cross-sectional cohort study, 104 apartment-type family residences with acclimatization systems in Split-type rest rooms were evaluated. Positive results for dermatophytes were obtained in 34 of the 104 samples (33.65%), while filamentous fungi and yeasts were 27 cases (25.96%). The concentration ranged between 17 and 227 CFU/m3 and from 9 to 46 CFU/m3 for dermatophytes and for filamentous and yeasts, respectively. The species of dermatophyte fungi isolated in the air were Trichophyton rubrum and Trichophyton mentagrophytes, the most frequent being Trichophyton rubrum, which appeared in 73.52% of the positive samples, representing a frequency of occurrence of 24.04%; mixed colonies with both species at the same time were not observed in any of the samples. In the group of non-dermatophytes, Penicillium spp. it was present in 10.58% of the evaluated samples, being the most prevalent fungus of this group, with counts that reached up to 46 CFU/m3. This group in the 27 positives, evidenced at least two species of fungi and additionally in 14 cases a yeast. This study showed that not applying corrective measures and the air conditioning cleaning system can compromise the health of its inhabitants, especially due to respiratory problems, due to the presence of fungi.
