Behind the Build: Air Quality – Protecting the Home from What You Don’t See

One of the details we pay close attention to during every renovation is air quality. You may not see it in photos, but it plays a huge role in how your home feels, and how healthy it is.

For this project, we created a new mechanical room at the back of the powder room, housing the second furnace for the home’s upper levels. To reach those bedrooms and bathrooms, the ductwork had to pass through the garage, the only spot in the house where bulkheads were visible.

That, of course, introduced another problem: air quality and temperature consistency. Garages are unconditioned spaces, often exposed to fumes, dust, and outdoor temperatures. Running ducts through that environment can lead to energy loss and even potential contamination if not handled properly.

So, we took extra precautions. Every joint in that ductwork was sealed as it was installed, ensuring no air leakage. Then we applied closed-cell spray foam over every bulkhead and encapsulated every pipe running through the space. The result is a system that keeps conditioned air exactly where it belongs, cool in the summer, warm in the winter, without any crossover from the garage environment.

It’s not the kind of thing you’ll notice when you walk into the house. But it’s absolutely something you’ll feel — fresher air, balanced temperatures, and peace of mind knowing your home’s invisible systems are working hard behind the scenes.

Because the best builds aren’t just beautiful; they’re built to breathe right.

Tune in to hear about this strategy from Kellen.

💬 FAQ: How Does Ductwork in a Garage Affect Air Quality?

Q: Is it safe to run ductwork through a garage?
A: It can be, but it requires careful planning and sealing. Garages are considered “unconditioned” spaces — meaning their air isn’t filtered or temperature-controlled. Without proper insulation and sealing, fumes, odors, or temperature fluctuations could travel through the ducts into the living areas.

Q: What steps does Juxta take to protect indoor air quality?
A: We seal every duct joint during installation and then encapsulate the entire run with closed-cell spray foam. This not only prevents leaks but also acts as a barrier between conditioned and unconditioned air. It helps maintain clean airflow and reduces condensation risks.

Q: What’s the benefit beyond air quality?
A: Properly sealed ducts are more energy efficient. The HVAC system doesn’t have to work as hard to deliver consistent temperatures throughout the house — which means a quieter, more efficient system and lower energy costs over time.
