Designing an HVAC system is more than just picking equipment. It’s about creating a system that works efficiently, meets code, installs easily, and performs well long-term. Whether you’re working on a multifamily project, hotel, or assisted living facility, smart planning makes all the difference.
At AE Air, we help engineers, contractors, and developers meet today’s HVAC needs with flexible, code-ready solutions. Use this 6-step checklist to guide your design from the start.
1. Define the Project
Start by gathering key details about the building. Ask:
- What type of building is it? (Multifamily, hospitality, assisted living?)
- How many units or zones will it have?
- What’s the total square footage?
- Are there special indoor air quality needs?
- What’s the expected heating and cooling load per zone?
A clear project profile helps you choose the right equipment from the beginning.
2. Select the Right System
AE Air offers reliable, efficient HVAC products for both new builds and replacements, including:
When selecting your system:
- Match the unit size to the layout and access points
- Pick models that are compact and easy to install
- Choose A2L-compliant units to meet upcoming refrigerant rules
- Focus on quiet, efficient airflow — especially in smaller spaces
3. Do the Math
Proper sizing is key to comfort and efficiency. Use Manual J or a similar method to calculate load requirements. Be sure to:
- Include factors like insulation, windows, occupancy, and usage
- Size equipment and ductwork to match real-world loads
- Avoid oversizing — it wastes energy and leads to poor comfort
Wrong sizing leads to high bills, noise, and frequent service calls.
4. Plan Airflow & Ductwork
Airflow design directly impacts comfort and performance. To optimize:
- Reduce pressure drops with efficient duct layout
- Place supply and return registers in smart locations
- Include zoning or balancing where needed
- Use AE Air’s quiet, easy-to-service fan coils
Need a low-clearance option? Our HH Series delivers high airflow in slim, compact designs.
5. Stay Code Compliant
HVAC codes are changing fast. Make sure your system complies with:
- ASHRAE 62.1 & 90.1 for ventilation and energy efficiency
- The upcoming 2025 A2L refrigerant transition
- Local codes — including ventilation, fire barriers, and access clearances
Working with AE Air ensures you stay ahead of these changes.
6. Coordinate Early with Other Trades
HVAC doesn’t work alone. Avoid costly delays by coordinating with:
- Plumbing, electrical, and structural teams
- Ceiling heights and mechanical clearances
- Access panels, drain paths, and service points
Good coordination means fewer issues during installation — and fewer surprises later.
