☀️❄️ YOUR AC MIGHT NOT BE THE PROBLEM.
We’ve all heard the advice:
“Close the vents in the rooms you don’t use.”
“Buy a bigger AC — it’ll cool faster.”
“Crank the thermostat way down when you get home.”
“Just add more insulation.”
“Close the curtains and you’re good.”
But building science tells us there’s a little more to the story.
🏠 Your home is a system.
Your air conditioner, ductwork, insulation, windows, attic, air leaks and even the way sunlight hits your house all work together.
For example:
🔵 Closing vents can increase pressure in your duct system and contribute to duct leakage.
🔵 Oversized AC units can short-cycle, leading to uneven temperatures and poorer humidity control.
🔵 Cranking down the thermostat doesn't make the system cool your house faster.
🟢 Air-sealing before adding insulation can make a big difference because insulation can't stop air that's simply moving through the building envelope.
🟢 Exterior shading can stop solar heat before it makes its way through your windows.
And one of the simplest things you can do?
🔵 Change that HVAC filter. A restricted filter can reduce airflow and make your system work harder.
🌎 At Claro Home Inspections, we believe energy efficiency isn't just about saving money on a utility bill.
It's about comfortable homes, less wasted energy, responsible use of resources, and a healthier environment for the communities we live in.
That's why we like building science.
Don't just look at the air conditioner. Look at the HOUSE.
