Your Home’s Dirty Little Secret: One Interior Design Tip That Could Save You Thousands

In a recent episode of Designing in 5D, I sat down with Steve Reynolds, founder of Gulfshore Air, to talk about why ignoring your HVAC during an interior design remodel is one of the most common—and costly—mistakes homeowners make.

And let me tell you: this is your home’s dirty little secret.

Why HVAC planning should be part of your remodel from day one.

When people start dreaming about their remodel, they often picture countertops, flooring, or paint colors—not air ducts. But there’s one crucial system silently running behind your walls that can make or break the success of your renovation: your HVAC system.

What Most Homeowners Get Wrong

Most people don’t think about their heating and cooling systems until something breaks. But Steve shared that he’s seen time and time again how poor HVAC planning can derail an otherwise stunning remodel.

From mold buildup in old ductwork to improperly sized units that can’t handle new square footage, these oversights don’t just impact comfort—they can seriously affect your health, utility bills, and even the longevity of your finishes.


👎 Real Talk: What Can Go Wrong

Here’s what can happen if HVAC isn’t considered upfront:

  • Brand new ceilings have to be ripped out because of old or moldy ductwork

  • Contractors unknowingly trap moisture or poor airflow into new additions

  • Clients are forced to cut the pretty things from their budget to retrofit HVAC later

  • Brand new units get clogged with dust and drywall debris during construction

  • Indoor air quality suffers, leading to allergies, mold, and even illness

Steve shared a story about a home where beautiful ductwork was ruined by a careless subcontractor—and the homeowner had to pay thousands to fix it.


🛠️ The Design Tip That Changes Everything

Bring your HVAC pro in at the start.

Not mid-demo. Not when the ceilings are going up. Not after the finishes are ordered.

In our EED Process at Elizabeth Erin Designs, we advocate for early, intentional collaboration with professionals—including HVAC specialists like Steve—during the initial planning phase. That way, we can value-engineer the right solutions, protect your budget, and prevent surprise costs down the line.

Whether you’re:

  • Knocking down a wall

  • Adding a new room

  • Rethinking your ceilings

  • Trying to solve for hot/cold spots
    …the airflow and air quality must be part of the conversation.


🌿 What You Can Do Today

Want to know how your current system is doing?
Steve recommends grabbing an affordable tool to measure your home’s humidity levels:
🛒 This AcuRite Hygrometer (only ~$15!) can tell you right away if your home is at risk for mold or poor air quality.

🧠 Final Thoughts

Your remodel deserves more than just surface-level beauty—it deserves a healthy foundation.
Think of your HVAC system like the lungs of your home. If it’s overlooked, your investment—and your well-being—could suffer.
