Between Cool & Chaos - Cejas Cooling & Construction

Because comfort isn’t guaranteed — it’s engineered.

They say comfort is a luxury. We say it’s engineered. Join me where pressure meets poetry and cooling a room becomes an act of defiance.

A meditation on the invisible battle between man and climate—and the steel, copper, and current we wield to win it.

Between Time & Comfort

Before comfort had a thermostat, it had a story. A story of fire, frost, and the engineers who dared tame both. Journey through the decades where human resilience met mechanical revelation, and learn how we carved climate out of chaos

Between Cool and Catastrophe

It’s not the thermostat that keeps you cool—it’s a volatile cocktail of pressure, chemistry, and molecular violence humming behind the drywall. This is refrigeration 101: walking a razor-thin line between engineered balance and total system collapse.

Between Heat and Heaven

Unlock the hidden laws that govern your comfort—temperature as the pulse of matter, heat as a restless wanderer, and pressure as the invisible weight of the world above us. This isn’t just physics, it’s the secret language your HVAC system speaks fluently.

Between Pressure and Ice

Discover how modern refrigeration systems manipulate pressure, temperature, and phase change to fight heat and preserve comfort. Learn the science behind compressors, evaporators, refrigerants, and the delicate balance that keeps your world cool.

Between Sweat and Science

Uncover how temperature, humidity, and airflow create true indoor comfort. This deep dive into psychrometrics reveals how HVAC pros use science, not guesswork, to control moisture, energy, and the invisible feel of the air around you.

Between Substance and Spark

Explore the physics behind your comfort—how gases behave, how energy moves, and why every flicker of electricity and flow of refrigerant obeys the laws of matter and thermodynamics. This isn’t just science, it’s the heartbeat of HVAC.

Between Phase and Flow

Discover how the evaporator sets the stage, how superheat protects the compressor, and how phase changes turn science into symphony. This is the unseen choreography of pressure, heat, and transformation that powers every refrigeration cycle.

Between Evaporation and Pressure

Learn how airflow, ambient heat, refrigerant load, and even humidity all conspire to push your system into balance—or chaos. This isn’t just about readings on a gauge, it’s about understanding the pulse of pressure and the poetry of BTUs.

Between Pressure and Pulse

Discover the heartbeat aka compressor of refrigeration systems—from subtle suction shifts to the quiet scream of a failing compressor. Learn to decode the pressures, temperatures, and frost lines that separate true diagnostics from guesswork.

Between Sky and Skin

Explore how sunlight, insulation, and airflow collide to shape the climate inside your walls. This is where HVAC meets architecture, where what’s above us and what surrounds us decides whether comfort thrives…or wilts.

Between Sparks and Circuits

From the quiet flow of electrons to the brute force of motors, this is your guide to how matter and energy shape comfort, one spark at a time.

Between Oil and Machine

Unlock the soul of the system—from the chemistry of refrigerants to the physics of superheat, this guide dives into the fluids, pressures, and components that turn cold air into a calculated artform.

Between Precision and Control

Step into the quiet heart of the cycle—where pressure drops, boiling begins, and a tiny valve decides whether your system thrives or crashes. Learn how TXVs and EEVs tame entropy with every degree of superheat.

Between Fire and Comfort

Before the warm air fills your home, there’s a controlled explosion behind the scenes—an engineered blaze where molecules collide, pressure builds, and precision makes the difference between comfort and catastrophe. This is combustion, decoded.

Between Sparks and Silence

Discover the understated power of electric heat—from the elegance of resistance heating to the choreography of sequencers and contactors. In a world chasing cleaner energy, this is comfort without combustion, warmth without warning.

Between Breath and Burden

Explore how ductwork, filters, and forgotten corners of the HVAC system shape the air we breathe—and why the fight for clean indoor air is no longer optional. This is about lungs, not just load calculations.

Between Signals and Circuits

Discover how thermostats, sensors, relays, and control boards form the nervous system of HVAC—translating temperature and pressure into precision comfort. When these signals go silent, everything else falls apart.

Between Wind and Will

Explore how airflow shapes every breath of indoor comfort—from duct design to static pressure, CFM, and the hidden physics that determine whether a system breathes or breaks.

Between Walls and Windows

Understand how heat moves through your home—from wall insulation to solar gain—and why load calculations shape the size, efficiency, and longevity of your HVAC system.

Between Loss and Load

Explore how blower doors, duct leakage tests, and infrared scans reveal the unseen gaps stealing your comfort—and how a true energy audit becomes the blueprint for a smarter, healthier home.

Between Velocity and Volume

Uncover the hidden physics of airflow—from duct sizing to pressure balancing—and learn how mastering invisible forces turns HVAC systems from noisy guesswork into precision comfort.

Between Torque and Tenacity

Explore the unsung force behind HVAC systems—how motors turn electricity into motion, torque into flow, and quiet grit into comfort you never notice… until it stops.

Between Panels and Practice

Step into the art and grit of HVAC installation—where ductwork meets discipline, voltage demands precision, and every bolt, strap, and brazed joint becomes the spine of comfort itself.
