Commercial HVAC Equipment Selection Guide 2023: Professional System Design & Installation

Real Commercial Case Study: A 4,200 sq ft restaurant in Addison installed an oversized packaged unit based on “industry standard” sizing. Within 6 months, they faced:

• $3,400 monthly energy bills from inefficient short cycling
• Constant humidity problems creating customer comfort issues
• Food spoilage losses from temperature and humidity fluctuations
• Equipment failures costing $12,000 in repairs during peak season

The devastating total: $85,000 in lost revenue, energy waste, repairs, and emergency replacement before professional system redesign solved their problems.

Professional system redesign with properly sized, restaurant-specific HVAC equipment cut energy costs to $1,850 monthly, eliminated humidity issues, and provided reliable operation that protected their business reputation and profitability.

The critical truth: 74% of North Texas commercial HVAC installations use inappropriate equipment selection, costing businesses thousands in energy waste, comfort problems, and premature equipment failure.
