Commercial HVAC Retrofit for a Truck Service Center in Illinois, USA

Floor-Standing Heating & Cooling Solutions for Commercial Office Spaces

YUJU EnvironTech is supporting a preliminary HVAC replacement inquiry for a truck service center located in Montgomery, Illinois, within the greater Chicago metropolitan area. The customer is evaluating a cost-effective alternative to an existing rooftop HVAC system that is no longer operating properly.

The proposed solution involves approximately 10 commercial floor-standing air conditioning systems with both heating and cooling functions, designed to improve indoor comfort while evaluating alternatives to replacing the entire rooftop HVAC system.

01. Project Background & Customer Requirements

Customer-provided reception area showing the existing suspended ceiling and air distribution outlets. The interior layout provides a useful reference for evaluating commercial HVAC replacement options.

The facility operates as a truck service center with associated commercial office areas. Its location in northern Illinois creates demanding seasonal HVAC requirements, including hot summers and cold winters.

The customer is considering independently installed floor-standing heat pump systems instead of a complete rooftop equipment replacement.

Note: Final capacity, equipment configuration and quantities are subject to site assessment and load calculations.

02. Commercial Cooling Capacity & Coverage

Existing private office with ceiling-mounted air outlets, windows and internal equipment. Room layout, glazing, occupancy and heat gains must be considered when calculating the required cooling and heating capacity.

For preliminary commercial office sizing, a 60,000 BTU/h (5 Ton) system may cover approximately 1,500–2,000 square feet under typical operating conditions.

These values are intended for initial capacity discussions only. Actual equipment selection depends on building insulation, ceiling height, glazing, occupancy, internal equipment loads, ventilation and local design conditions.

Heating capacity must be evaluated separately, particularly for Chicago-area winter conditions.

03. Proposed Floor-Standing HVAC Solution

YUJU is evaluating commercial floor-standing heat pump configurations that can deliver heating and cooling without necessarily requiring a complete replacement of the existing rooftop unit.

YUJU EnvironTech provides commercial floor-standing air conditioner options with different cabinet designs and project-specific configurations. Cooling capacity, heating performance, available models and electrical specifications are subject to technical confirmation.

Final product selection will depend on available equipment specifications, electrical compatibility, refrigerant selection, outdoor unit placement, heating performance and applicable US safety requirements.

04. Rooftop HVAC Replacement vs. Floor-Standing Systems

Replacing an entire rooftop HVAC unit can involve additional costs for rooftop access, lifting equipment, ductwork modification and installation labor.

Floor-standing split systems may provide an alternative for selected office spaces, especially where independent zone control is desirable. However, the existing rooftop system may also serve ventilation or other building areas that must be evaluated before conversion.

YUJU's preliminary engineering approach focuses on comparing equipment costs, installation requirements, heating performance, ventilation needs and overall project feasibility rather than considering the purchase price alone.

05. OEM & Commercial Project Support

Beyond equipment supply, YUJU EnvironTech supports importers, HVAC contractors and commercial project buyers with flexible sourcing and engineering coordination.

• Equipment Selection: Commercial floor-standing, ducted heat pump and rooftop HVAC options.
• OEM & Private Label: Branding and specification customization according to order requirements.
• Technical Coordination: Capacity selection, equipment documentation and installation planning support.
• Spare Parts Support: Replacement parts and remote technical assistance.
• International Supply: Export quotation, packing arrangements and shipping coordination.

06. Project Status & Next Steps

This Illinois commercial HVAC project is currently at the preliminary inquiry and budget evaluation stage. No equipment delivery or installation has been confirmed.

The next stage involves confirming floor area, existing system conditions, required heating and cooling capacity, electrical specifications and installation constraints before preparing a formal equipment proposal.
