At MCX Air Systems, our System Design service takes the guesswork out of building or upgrading your HVAC setup. Using industry-standard Manual J load calculations, we assess your building’s size, layout, insulation, window exposure, and occupancy to determine the precise heating and cooling capacity your space requires. From there, we design a complete system — including equipment selection, ductwork layout, zone planning, refrigerant line routing, and thermostat placement — all tailored to your property and budget.

Every design we produce is optimized for energy efficiency and fully compliant with California’s Title 24 energy code, ensuring your system performs at its best from day one while keeping long-term operating costs low. Whether you’re constructing a new building, replacing an outdated system, or expanding an existing setup, MCX Air Systems delivers a design that’s built for your space, your climate, and your comfort — backed by licensed expertise and real-world installation experience.
