Request ServiceLaunched in spring 2020, our Healthy Air Initiative helps protect our partners, their employees and their guests.
MAS has an affiliate relationship with PreVasive, the maker of BAC (Botanical Antimicrobial Cleaner). BAC is a ready-to-use cleaner with safe active ingredients, including whole essential oil and white thyme. When we service any HVAC unit, we clean and treat the evaporator with BAC to help circulate clean, treated air.
Many of our multi-location restaurant partners have had MAS add these clean air protocols to their next round of preventative maintenance. Our team has completed all necessary field training.
The evaporator coil is cleaned with a very light coil cleaner, the drain pan is cleared, and the compartment is vacuumed out.
BAC is applied with a pump sprayer as a very fine mist, in measured amounts, to the evaporator coil and compartment, then left to dry.
Add a proactive filter change to your service. MERV 13 filters help capture smaller particles, unwanted bacteria and virus carriers.
Ultraviolet air purification systems install easily in existing equipment. They kill bacteria, viruses and mold, and reduce odors and VOCs.
