When managing a commercial property in Riverside, CA, staying compliant with HVAC regulations isn’t just about avoiding fines—it’s about ensuring energy efficiency, tenant comfort, and long-term cost savings.
At Avalon Air Conditioning & Heating, we specialize in helping businesses navigate California’s complex HVAC codes while optimizing performance and efficiency. In this post, we break down the key HVAC regulations affecting commercial buildings in Riverside and how to ensure your system is compliant.
1. California Title 24 Energy Efficiency Standards
What is Title 24?
Title 24 of the California Building Standards Code sets energy efficiency regulations for commercial HVAC systems. It requires:
• High-efficiency HVAC units to reduce energy consumption
• Demand-controlled ventilation (DCV) in buildings with high occupancy
• Smart thermostats & building automation systems (BAS) for energy management
• Regular duct leakage testing to prevent efficiency loss
Why It Matters:
Non-compliance can result in hefty fines and higher energy bills due to inefficient HVAC operation. Avalon Air helps businesses upgrade to Title 24-compliant systems and optimize energy savings.
2. California Air Resources Board (CARB) Refrigerant Regulations
Why Businesses Need to Phase Out HFC Refrigerants
The California Air Resources Board (CARB) has set strict rules on refrigerant use, targeting hydrofluorocarbons (HFCs), which contribute to climate change.
• Commercial HVAC systems using R-410A or R-134a refrigerants must transition to low-GWP (global warming potential) alternatives.
• Businesses must report refrigerant leaks in systems containing 50+ pounds of refrigerant under the RMP Rule (Refrigerant Management Program).
How Avalon Air Helps:
We offer refrigerant retrofitting and leak detection services to help businesses transition before deadlines hit.
3. South Coast Air Quality Management District (SCAQMD) Compliance
Regulations for Rooftop Units (RTUs) & Boilers
Riverside falls under the jurisdiction of the South Coast Air Quality Management District (SCAQMD), which enforces strict emissions limits on HVAC equipment.
• Rule 1111: Requires low-NOx (nitrogen oxide) emissions for commercial heating equipment.
• Rule 1146.2: Sets emissions standards for boilers & water heaters above 75,000 BTU/hr.
Why It Matters:
Non-compliant systems may be banned from operation, forcing property owners to replace HVAC units before their expected lifespan ends.
Avalon Air can help assess whether your current HVAC system meets SCAQMD regulations and recommend cost-effective compliance solutions.
4. Indoor Air Quality (IAQ) Requirements for Commercial Buildings
New Filtration Standards for Workplaces & Public Buildings
With California’s growing focus on air quality, commercial properties in Riverside must meet higher indoor air quality (IAQ) standards.
• MERV 13 Filters: New regulations require commercial buildings to upgrade to MERV 13-rated air filters to reduce airborne contaminants.
• Ventilation Improvements: California OSHA (Cal/OSHA) mandates enhanced ventilation rates in workplaces to protect employee health.
• Air Purification & UV-C Technology: Many buildings must install air scrubbers or UV disinfection systems for compliance.
How Avalon Air Can Help:
We offer IAQ testing, filtration system upgrades, and HVAC modifications to ensure your business meets the latest IAQ standards.
5. HVAC Maintenance & Inspection Requirements
Annual Inspections & Preventative Maintenance
Under California law, commercial HVAC systems must undergo routine inspections and maintenance to remain compliant with Title 24 & SCAQMD rules.
• Annual HVAC system check-ups are required for commercial buildings to maintain energy efficiency.
• Duct work inspections help identify leaks that could be causing up to 30% energy loss.
• Filter replacements & coil cleaning are essential to meet indoor air quality (IAQ) standards.
Avalon Air’s HVAC maintenance programs help businesses stay compliant while avoiding costly repairs.
