Bellows Plumbing, Heating, Cooling & Electrical can help you simplify California’s complicated HVAC building code, focusing on Title 24, the state’s primary code for HVAC systems. Compliance with California heating and air conditioning laws is critical for any construction or renovation project.
Here’s a brief guide to help you understand the requirements of residential HVAC code and navigate the California air conditioning code efficiently.



Title 24 Commercial HVAC Code Requirements

Title 24 aims to improve energy efficiency standards across commercial and residential buildings in California. Compliance involves proper sizing of heating and cooling equipment, reducing air leakage, and installing energy-efficient control systems. The US Energy Information Administration (EIA) highlights significant energy use for air conditioning and heating. Title 24 addresses this by setting standards for duct installation, HVAC sizing, and thermostats.

Duct Installation Standards: Ensuring Energy Efficiency

Under Title 24, HVAC ductwork must be sealed and insulated to prevent air leakage, complying with the California air conditioning code. Adherence to Home Energy Rating System (HERS) standards is crucial.

Heating and Cooling Equipment Sizes, Optimal Efficiency

Proper calculation of heating and cooling loads is essential to avoid inefficient equipment operation as per California’s air conditioning laws. Correctly sized equipment maintains comfort without excessive cycling.

Thermostats: Enhancing Control and Efficiency

Installation of setback or smart thermostats is mandatory under Title 24 to reduce energy consumption during unoccupied periods, meeting residential HVAC code requirements. Each thermostat must offer programmable features.

Zonal Control and Energy Optimization

Implementing zonal controls can reduce energy consumption by deactivating HVAC systems in unused areas, aligning with California’s air conditioning code. Buildings with multiple climate zones may qualify for energy compliance credits.

Implications for Property Owners, Managers, Engineers, and Architects

California’s focus on energy conservation through codes like CalGreen and Title 24 impacts HVAC projects significantly. Bellows can streamline compliance and install energy-efficient HVAC systems tailored to meet California air conditioning laws.
