Site assessment and sizing: the foundation of a reliable installation

A precise site assessment prevents many common failures. Our approach includes:

• On-site walk-through and documentation of the installation space, clearances, and utility access
• Detailed load calculations tailored to the application: Manual J or residential sizing for home units and commercial refrigeration load analysis for walk-ins and display cases
• Evaluation of existing ductwork, insulation, drains, and electrical capacity
• Assessment of environmental factors specific to Miramar, such as roof exposure, direct sun, prevailing wind direction, and proximity to salt air and roadways
• Identification of necessary structural supports, curb-mounted units, hurricane straps or wind-resistance considerations, and compliance with local permitting requirements

Proper sizing addresses both steady-state load and transient loads like frequent door openings, warm product loads, and defrost cycles. Oversizing leads to short cycling; undersizing leads to temperature instability. Accurate calculation prevents both.

Choosing the right unit for Miramar conditions

Selecting equipment involves balancing capacity, energy efficiency, refrigerant type, and durability. Considerations we evaluate:

• Corrosion resistance: units with coated coils, stainless steel components, or protective coatings are preferred near coastal environments to resist salt corrosion
• Energy efficiency: high-efficiency compressors and components reduce operating costs and may qualify for local utility incentives or rebates
• Refrigerant compatibility: systems must use refrigerants compliant with current EPA regulations and the Florida Building Code. Newer low-GWP alternatives are available for many applications
• Load profile: variable-capacity compressors and modulating controls can optimize performance for spaces with fluctuating demand
• Defrost method: electric defrost, hot gas defrost, and smart defrost strategies are selected based on use case and energy trade-offs
• Accessibility and serviceability: equipment should be installed to allow safe and easy access for maintenance and service
