Whether it’s a high-rise in New York, a sleek office in London, or a temperature-sensitive warehouse in Dubai, the “lungs” of these structures are the HVAC system that can either be a masterpiece of engineering or a massive energy drain.
At Fluxiss, we don’t just “install ACs.” We engineer environments. Through research and years of seeing projects go from messy sketches to high-performance realities, we’ve realized that the difference between an “okay” building and a “Gold-standard” one usually comes down to three non-negotiable steps: precise calculations, smart picking, and surgical ducting.
One thing about failed builds is that “eyeballing” the size of an AC is the fastest way to ruin a budget. If the system is too big, it cycles on and off constantly (short-cycling), killing the equipment and leaving the air humid. If it’s too small? Well, enjoy the heat.
For every project we handle, from Los Angeles to Abu Dhabi, we use HVAC load calculation software like Carrier HAP or IESVE. These aren’t just calculators; they simulate the sun’s path, the number of people in the room, and even the heat given off by your computer monitors.
We often get asked, “Which system is better?” The truth is that it depends entirely on your local “Part L” or “ASHRAE” codes. In 2026, the shift is massive. In the UK and Europe, we’re seeing a total takeover by heat pump system design because of the push for electrification. Meanwhile, for massive industrial builds in the USA or UAE, chiller system design remains the king of heavy-duty cooling.
At Fluxiss, HVAC system selection is a personal experience for us. We sit down with the client’s budget and the building’s 20-year energy outlook. We look at energy-efficient heating and cooling systems that aren’t just green on paper but actually lower your monthly utility bills in cities like Chicago or Manchester.
You can have the best chiller in the world, but if your duct sizing design is off, you’ll have a noisy, drafty mess. We’ve walked through buildings where the “whistling” of the vents was enough to drive anyone crazy. That’s usually a sign of poor mechanical duct layout planning.
Our team focuses on optimized airflow and ventilation design. We use Revit MEP to create mechanical drawings for HVAC projects that ensure:
We provide a full-spectrum HVAC mechanical design package:
At the end of the day, HVAC system design isn’t just about pipes and wires; it’s about the comfort of the people inside. A well-designed system transforms a workspace, making it more productive and significantly cheaper to run. Whether you are in the USA, UK, UAE, or Europe, Fluxiss is here to make sure your building’s lungs are in perfect health.

Imagine wearing a winter coat in July; that’s an oversized AC. A proper heating and cooling load calculation prevents "short-cycling," which destroys compressors. At Fluxiss, we use HVAC sizing and capacity planning to ensure your system only uses the energy it actually needs, saving you thousands.
With current energy-efficient HVAC design trends, heat pump system design is winning for carbon-neutral goals, especially in the UK and Europe. However, for massive cooling demands in the UAE, chiller system design is often still the most robust choice. We help you choose based on ROI.
In case your ductwork design is either leaky or limited, your fans will be forced to work twice. This is referred to as high static pressure. We optimize the airflow and the design of your ventilation which saves you the load on your fans and can save you as much as 15 percent of your HVAC energy.
Absolutely. We specialize in HVAC design and drafting that meets local codes in the USA (ASHRAE) and UK (CIBSE). Our mechanical drawings for HVAC projects are detailed enough for any contractor to follow, ensuring the physical build matches the high-performance engineering on paper.
We’re proudly serving clients across the USA, UK, UAE, and Europe. From corporate giants to research labs and the shipping industry,
