When it comes to heating and cooling, everyone’s an “expert” — until the energy bills spike or the system breaks down mid-summer. From old wives’ tales to well-meaning advice from your neighbor, HVAC myths have been circulating for decades. But believing these myths can cost you comfort , efficiency , and money . It’s time to set the record straight. Let’s bust the 10 most common HVAC myths —once and for all. ❌ Myth #1: "A bigger HVAC system means better performance." Truth: An oversized system doesn’t cool or heat faster—it short cycles. This causes uneven temperatures , higher energy bills, and excessive wear and tear . Always size your system based on proper load calculations, not just square footage. ❌ Myth #2: "Closing vents in unused rooms saves energy." Truth: Nope. Modern HVAC systems are balanced. Closing vents can increase duct pressure , causing leaks or damaging your system. It actually makes your HVAC work harder , not smarter. ❌ Myth #3: ...

For decades, air conditioning has been synonymous with comfort, providing a much-needed escape from soaring temperatures. But modern AC systems are far more than just cooling devices. They are evolving rapidly, driven by a global push for energy efficiency, improved indoor air quality, and seamless integration with our increasingly smart lives. As a global HVAC and MEP Consultant with over 30 years of experience, I've witnessed firsthand the transformative journey of this essential technology. Let's delve into what makes today's AC truly remarkable and what we can expect from the climate control solutions of tomorrow. Beyond Cooling: The Multi-Faceted Benefits of Modern AC The primary function of air conditioning remains cooling, but the latest innovations deliver a host of other advantages: Exceptional Energy Efficiency: Gone are the days of energy-guzzling units. Modern AC systems boast significantly higher Seasonal Energy Efficiency Ratio (SEER) ratings, with some reach...

In the intricate dance of HVAC systems, the Air Handling Unit (AHU) plays a pivotal role. It's the heart of a building's ventilation and climate control, responsible for filtering, heating, cooling, and distributing air throughout a space. Given their critical function and often bespoke nature, ensuring these units perform flawlessly from day one is paramount. This is where the concept of the Factory Acceptance Test (FAT) becomes indispensable, and it's the precise focus of the book, "Air Handling Unit, Factory Acceptance Test (FAT)" by Charles Nehme. Charles Nehme, a highly respected global HVAC and MEP Consultant with over three decades of international experience, brings his extensive knowledge to the forefront in this specialized guide. His profound understanding of building systems, honed across complex industrial, large-scale commercial, and intricate residential projects worldwide, makes him uniquely qualified to address the crucial topic of AHU validation ...
