Rooftop Units


Rooftop Units

We make it our business to service yours.

Over the past twenty years, the concern over the indoor air quality of businesses has grown. Studies show that people spend as much as 90 percent of their time indoors. Pollutants such as dust, dead skin cells, dirt, allergens, mold spores, and many other contaminants collect in the HVAC system of your commercial building and filter throughout the air you breathe. Amistee offers complete cleaning of the entire ventilation system, including the rooftop unit, which guarantees the removal of anything that has the potential to become airborne. Our team of professionals is dedicated to providing a thorough and comprehensive cleaning that will ultimately improve the indoor air quality of your commercial facility.

Rooftop units are typically installed in mid-sized businesses and represent over 60 percent of the commercial space in the United States. A rooftop unit (RTU) is an air handler that is designed for outdoor use. During the heating or cooling process, it is used to circulate air. It is made of many components including an air filter, a coil, and a blower. As the air flows over the components of the rooftop unit, debris and particulates can build up and be circulated into your indoor air. Without proper cleaning and maintenance, the rooftop unit can also increase energy costs and decrease the lifetime of your heating and cooling equipment. Amistee takes pride in offering a complete cleaning of your rooftop unit so you can be confident that the work was done properly.

Amistee has both the knowledge and experience to clean every aspect of your HVAC system, including the rooftop unit and all its components. Our professional technicians are trained according to the National Air Duct Cleaners Association (NADCA) to give them a full understanding of the most innovative and up-to-date methods used in the commercial duct cleaning industry. We also put our technicians through a thorough and comprehensive training program at our on-site training facility, which offers hands-on experience before they even enter the field. The owners of Amistee take the additional steps needed to make sure our team members are properly prepared and qualified to represent our company name.

A rooftop unit has many components and without the proper knowledge, a cleaning can cause more damage than good. Amistee understands how important it is to have the rooftop unit cleaning done the right way. That is why we make every effort to be sure our team has the proper tools to provide an honest and quality commercial cleaning service.
