About the Jacksonville Sheriff’s Office

The John E. Goode Pre-Trial Detention Facility in downtown Jacksonville, FL is the largest pretrial detention facility in Duval County. The 13-level facility contains six main floors with mechanical levels in-between and a basement. Starting in 2019, Simpson Environmental provided the initial comprehensive inspection and subsequent repairs of the HVAC system and equipment of all 13 levels.

Being a detention facility, this work required careful consideration for both security practices and the safety of the Simpson Environmental team. Mechanical repairs were completed one-half floor at a time in non-sequential order, determined by which section of which floor had the least number of occupants at any given time. The majority of the work was completed at night while inmates were asleep, and the Jacksonville Sheriff’s Office performed extensive background checks on all workers, providing them with new clearance badges prior to project commencement.

Several separate air handlers were serviced on every floor, as well as the replacement of the majority of the air dampers, general repairs, and duct cleaning performed on every floor of the facility. The COVID-19 pandemic went into full effect during this project, but Simpson Environmental was able to stay flexible and adjust to the customer’s revised schedule. Limited accessibility and maneuverability in a 24/7 operational facility makes work like this take twice as long as usual, but the project was completed efficiently within the expected timeframe regardless.

HVAC Air Duct and System Cleaning

EIS uses the latest technology and techniques to improve your building’s indoor air quality and HVAC system’s efficiency. Improper air duct maintenance is associated with many dangers, including the release of hazardous allergens and pathogens, which can cause health issues for the building’s inhabitants. 

Duct cleaning involves the cleanup of various heating and cooling system components of forced air systems. Regular maintenance and cleaning of these components help lessen the effects of airborne contaminants present in virtually any HVAC operating system. These include allergic reactions to dust, pollen or other debris, as well as reactions to microbiological contaminants.

We use specialty inspection equipment to assess air quality issues in your commercial and residential building’s air duct system. Our certified expert technicians ensure your air ducts are properly cleaned according to the National Air Duct Cleaning Association (NADCA).
