As buildings become smarter, codes get stricter, and business owners demand lower energy costs, HVAC designers face mounting challenges. Each stage of the process, from concept to commissioning, presents opportunities for innovation, but also pitfalls that can result in significant losses in efficiency, comfort, and reliability. Informed by 2025’s latest industry standards, here’s a deep dive into the Top 10 HVAC Design Mistakes in 2025 and the emerging best practices that will set your projects apart.

1. Failing to Perform Proper Load Calculations –

The foundation of a robust HVAC system is a thorough load calculation. Relying on outdated rules of thumb or rough estimates remains one of the industry’s costliest errors. Without accurate Manual J (for residential) or sophisticated software models, systems end up oversized, causing rapid cycling, poor humidity control, and higher utility bills, or undersized, resulting in inadequate comfort and short system life.

Today, designers must analyze building envelopes, orientation, occupancy, insulation levels, window specs, and microclimate data. New software enables precise modeling, taking into account advanced materials and dynamic occupancy to ensure every system aligns with real requirements, not arbitrary numbers.

2. Overlooking Ductwork Design –

Ductwork hides behind ceilings and walls, but it is the lifeblood of a successful HVAC system. Improper duct sizing, sharp bends, poorly sealed joints, or misrouted runs restrict airflow, create hot and cold spots, increase noise, and leave the system working overtime. Best practice calls for Manual D calculations that optimize duct sizing, minimize turns, and require professional sealing and insulation, especially in unconditioned spaces. High-performance systems are only as good as their weakest link.

3. Ignoring Modern Ventilation Principles –

Indoor air quality (IAQ) is not just a health issue; it’s a legal, reputational, and performance concern. Inadequate ventilation leads to elevated carbon dioxide, volatile organic compounds, allergens, and dangerous gases like carbon monoxide. Failing to meet ASHRAE Standard 62.1, or simply re-circulating stale indoor air, has drastic consequences. In 2025, IAQ-focused designs feature ERVs/HRVs (energy and heat recovery ventilation), real-time sensing, advanced air purification, and humidity controls. These create healthy, productive environments and help future-proof buildings against new standards.

4. Poor Thermostat and Controls Placement –

A smart control system will fail if its sensors are in the wrong location. Many designers still place thermostats near heat-producing devices, in direct sunlight, or in drafty hallways, guaranteeing inaccurate readings and erratic comfort. Thermostats, sensors, and control modules should always be centrally located, away from direct environmental influences. For larger sites, zoning with multiple sensors guarantees balanced comfort, allowing smart systems to truly “learn” occupant patterns.

5. Skipping Commissioning and Airflow Balancing –

Commissioning is the final exam of an HVAC install – yet it’s too often skipped. Without post-installation testing, airflow can remain unbalanced, refrigerant levels can be incorrect, and controls can be out of sync. The result is an operational building with hidden faults that cause callbacks and angry tenants or clients. All modern best practice demands rigorous, documented commissioning: airflow balancing, system startup tests, and digital verification logs are now industry standards for any high-performance project.

6. Lack of Coordination with Other Services –

Modern buildings require coordination between multiple trades: HVAC, electrical, plumbing, fire safety, and architecture. A failure to coordinate duct runs, equipment placements, or control access panels can quickly render a design impractical during construction. BIM (Building Information Modeling) and pre-construction coordination meetings prevent clashes and expensive site changes. Digital collaboration isn’t just a trend in 2025; it’s a mandatory best practice for competent designers.

7. Selecting Inefficient or Outdated Equipment –

Cutting costs by choosing older technologies is short-sighted. High SEER-rated components, inverter-driven compressors, heat recovery ventilators, and variable refrigerant flow systems offer dramatically better energy performance and comfort. Codes now require compliance with new efficiency standards for both residential and commercial systems, with green certifications becoming standard in competitive real estate. Incorporating equipment that meets future standards instead of just passing current ones is critical, especially given the rapid pace of HVAC innovation.

8. Weak Static Pressure Planning –

Static pressure is not just a theoretical number; it dictates how well air moves through your system. Once neglected, now it’s at the forefront for efficient, quiet operation. If static pressure exceeds manufacturer guidelines, even the most advanced equipment will struggle. Designers must measure, balance, and document static pressures, optimizing fan selections, duct sizes, and air distribution layouts accordingly.

9. Forgetting About Sustainability and Decarbonization –

Building project today faces pressure to be greener and more sustainable. Failing to specify low-GWP refrigerants, renewable energy integration (like solar-assisted HVAC or geothermal), and electrified heating systems means higher operating costs and compliance risks. Many modern projects already require net-zero energy solutions or seek carbon-neutral certification. Sustainability is not a buzzword; it’s a design imperative that affects building value, occupant health, and regulatory compliance.

10. Insufficient Documentation and Operator Training –

A sophisticated HVAC system is useless if operators don’t know how to run it. Incomplete maintenance docs, vague wiring diagrams, no training plans, and poor handover create a dependency on emergency service calls and expensive troubleshooting. Today, vendors provide digital manuals, QR-code guides, and training videos as part of the handover. Designer responsibility now extends beyond installation, ensuring facility managers and operators can easily troubleshoot and optimize the system for years to come.

Best Practices for HVAC System Design

Modern HVAC design is both a science and an art. It merges smart modeling, hands-on craftsmanship, digital collaboration, and a focus on health, efficiency, and sustainability. Here’s how the best in the business are excelling in 2025:
