Searching for a contractor that can clean the makeup air unit of your commercial building's HVAC system?

Amistee Air Duct Cleaning & Insulation is recognized as a leader in the commercial duct cleaning industry. Industrial buildings create some of the most polluted indoor air due to the activities that occur within the large facility. Contaminants and debris can accumulate within the building's ventilation system and can result in poor air quality and damage to the HVAC system. The Environmental Protection Agency (EPA) recommends having a preventative maintenance schedule in place to improve the indoor air quality of your commercial facility and maintain the longevity of your heating and cooling equipment.

According to the EPA, "The plan should include monitoring, inspecting and cleaning HVAC components such as outside air intakes, outside air dampers, air filters, drain pans, heating and cooling coils, the interior of air handling units, fan motors and belts, air humidification, controls, and cooling towers." Amistee provides professional and affordable cleaning of your entire ventilation system in order to improve the indoor air quality of your commercial building. There is not a ventilation system that will prove to be too complicated for Amistee. We have demonstrated our expert level of knowledge of commercial duct cleaning since 2005.

A makeup air unit is one essential part of your commercial building's ventilation system. Makeup air units are a mechanical device that introduces outside air into a space that has used all of its existing air. Typically, makeup air units are found in large industrial buildings because the existing air cannot be recirculated and outside air must be brought in. Hospital operating rooms, kitchens in restaurants, and manufacturing paint booths might also be practical applications for a makeup air unit. Typically, a large vertical shaft is connected to the unit and runs down through the building's multiple stories.

A horizontal duct is connected to the shaft and provides a source of air to each floor. When debris and contaminants build up within this section of the ventilation system, it is then filtered into your indoor air. Amistee takes pride in providing a comprehensive and complete cleaning of every component of your HVAC system, including the makeup air unit.

Amistee is a company that has built its reputation on integrity and hard work. The owners of Amistee believe that professionalism depends on every detail and that is why no part of our process is too small to be evaluated.
