Our Comprehensive Commercial HVAC Design Process
A high-performing HVAC system is the result of a deliberate and scientific approach. We leave nothing to chance, employing industry-leading standards and advanced building science to create a system that operates efficiently and reliably for years to come.
In-Depth Load Calculation (Manual J)
The cornerstone of any successful commercial HVAC design is an accurate load calculation. We go far beyond simple square footage estimates. Our team conducts a comprehensive analysis based on ACCA Manual J standards, evaluating factors unique to your facility, including:
- Total square footage and ceiling height
- Window size, type, and orientation
- Insulation levels in walls, ceilings, and floors
- Air leakage and building envelope tightness
- Local Garland climate data
- Occupant load and internal heat-generating equipment
- Roofing material and color
This precise calculation determines the exact heating and cooling needs of your facility, ensuring equipment is perfectly sized—not too large or too small.
Custom System & Equipment Selection
With the load calculation complete, we select the ideal commercial HVAC system. Oversized equipment cycles inefficiently, while undersized systems struggle to meet demand and drive up energy costs. We guide you through the best options—from high-efficiency air conditioners and boilers to commercial heat pumps and ductless systems—ensuring the chosen equipment meets your facility’s unique thermal profile and operational goals.
Meticulous Ductwork Design (Manual D)
Ductwork is the circulatory system of your HVAC system. Poorly designed ducts can lose up to 30% of energy. We use Manual D standards to design a duct system that delivers balanced airflow throughout your facility, optimizing duct sizing, layout, sealing, and insulation. The result is quiet, efficient operation and even temperatures throughout your building.
Strategic Zoning Strategies
Many commercial facilities experience uneven temperatures across zones or floors. HVAC zoning solves this by dividing the facility into separate zones with dampers controlled by independent thermostats. This approach provides precise temperature control where it’s needed and energy savings by not conditioning unused spaces.
Integrating for Energy Efficiency & Air Quality
Our designs go beyond temperature control. We incorporate energy-saving strategies and enhanced air quality features, including smart thermostats, high-MERV filtration systems, humidifiers/dehumidifiers, and energy recovery ventilators (ERVs). This holistic approach ensures your facility is comfortable, efficient, and healthy.
Who Benefits from Professional Commercial HVAC Design?
- New Commercial Construction: Builders and property owners start with a professional design to ensure energy-efficient, comfortable, and cost-effective operation from day one.
- Facility Renovations & Expansions: Modifying a facility changes its heating and cooling requirements. We design systems that integrate seamlessly with existing equipment or provide dedicated solutions for expanded areas.
- Existing Facilities with Operational Issues: Facilities experiencing uneven temperatures, inefficient systems, or high energy costs benefit from a full redesign to restore performance and efficiency.
- Complete System Replacement: Replacing aging HVAC units without a proper design can waste the investment. Our custom design ensures new systems operate at peak efficiency and deliver reliable performance.
