Heating, Ventilation, and Air Conditioning (HVAC) systems play an integral role in maintaining the comfort, safety, and energy efficiency of buildings. Whether it’s a cozy home or a large commercial property, HVAC systems ensure that indoor environments stay livable while optimizing energy use. But as the world continues to prioritize sustainability, energy efficiency, and health, HVAC codes and standards are evolving rapidly.
For building managers and homeowners, these changes demand attention. If you’ve been wondering how shifting HVAC standards affects your property—or what you can do to stay compliant—you’re in the right place. This article explores why HVAC standards are changing, highlights key updates, and offers practical strategies to help you avoid falling behind.
Why Are HVAC Codes Evolving?
Codes and standards for HVAC systems are continuously evolving, and for good reason. These updates reflect advancements in technology, a growing emphasis on environmental sustainability, and the need to improve the performance of systems that are critical to everyday life. Here are three key reasons driving these changes:
- Energy Efficiency Priorities: Government and industry bodies are introducing stricter energy efficiency targets in the fight against climate change. HVAC systems account for nearly 40% of energy use in buildings, making them a significant focus for energy-saving initiatives.
- Environmental Concerns: Changes in refrigerant types are a direct response to global efforts to reduce greenhouse gas emissions. Many older refrigerants have been phased out due to their high Global Warming Potential (GWP).
- Health and Safety: Improved indoor air quality (IAQ) is now a top priority. Updated standards emphasize proper ventilation and system design to promote health and well-being.
For building managers and homeowners, these updates mean more than just compliance paperwork—they can also lead to cost savings, improved system performance, and increased comfort when implemented effectively.
Recent Changes You Must Know
Wondering what’s changed in the HVAC landscape? Several key updates in recent years are impacting how buildings will operate moving forward. Below, we’ve broken down the most significant changes for you:
1. Higher Efficiency Standards
New regulations for HVAC equipment now require systems to meet higher energy efficiency standards. For example, the U.S. Department of Energy (DOE) introduced an updated Seasonal Energy Efficiency Ratio (SEER) rating standard in 2023, raising the minimum SEER rating for air conditioners to reduce energy usage.
How it impacts you: Expect newer HVAC systems to use up to 10–15% less energy compared to older models. If your system predates 2023, upgrading to one with a higher SEER rating could save you on utility bills while ensuring compliance.
2. Refrigerant Updates
Older refrigerants like R-22 (commonly known as Freon) are being phased out globally due to their environmental impact. New systems now use eco-friendlier refrigerants such as R-32 or R-410A, which have a much lower GWP.
How it impacts you: If your HVAC system still runs on phased-out refrigerants, it may become harder (and costlier) to maintain or repair. Consider transitioning to systems compatible with newer refrigerant types to future-proof your setup.
3. Advanced Ventilation Standards
The latest updates to standards by organizations like ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) emphasize better ventilation to improve IAQ. This includes increasing outdoor air exchange rates and using advanced filtration technologies.
How it impacts you: Proper compliance with updated IAQ standards ensures healthier indoor environments, especially in workplaces and shared spaces.
4. System Design and Sizing Guidelines
Codes now stress the importance of appropriate sizing and design for HVAC systems, focusing on minimizing inefficiencies caused by improperly sized equipment.
How it impacts you: Over-sized or under-sized systems waste energy and fail to maintain indoor comfort levels. Following updated sizing guidelines will ensure you maximize efficiency and performance over the long term.

Adapting to the Changes
Compliance with HVAC standards doesn’t have to be stressful. Here are some strategies to help building managers and homeowners stay ahead of the curve:
1. Schedule Regular Maintenance
Routine maintenance ensures your HVAC unit runs efficiently and meets code requirements. Partnering with a reliable HVAC service provider can help detect and resolve potential issues before they become costly.
2. Invest in System Upgrades
If your current HVAC system is outdated, upgrading to a newer, code-compliant model can save you money in the long run. Higher efficiency systems reduce energy consumption and qualify for government rebates in many cases.
3. Partner with Experts
Work with trusted professionals, like the team at Shafer’s HVAC, who can help analyze your current setup, recommend the best path forward, and guide you on code-compliant installations or retrofits.
