HVAC Ventilation Design for Clean, Healthy Air
Did you know many homes barely receive proper ventilation? Gaps, cracks, and random airflow aren't enough to provide the fresh, filtered air you need. At PV, we design ventilation systems that bring in the right amount of outdoor air, remove pollutants, and keep your home comfortable year-round.

The Science of Comfort
Engineered HVAC Solutions for Homes
At PV, we go beyond quick fixes to deliver data-driven solutions. Our in-house engineering team uses airflow testing, blower door evaluations, energy assessments, and more to tackle hotspots, hidden leaks, and inefficiencies.
Why Home Ventilation Design Matters
A properly designed ventilation system does more than crack a window or rely on unpredictable leaks.
Here's why it's so important:
Here's why it's so important:
- Cleaner Air — Quality ventilation removes stale indoor air and helps reduce allergens, pollutants, and odors.
- Balanced Humidity — In climates with extreme humidity or dryness, a mechanical system stabilizes indoor moisture levels and cuts down on mold or static problems.
- Healthier Living — Studies show that better air circulation can help alleviate allergies, respiratory issues, and frequent headaches.
- Energy Efficiency — When you control where air enters and exits, you often reduce the workload on your HVAC system—lowering long-term energy costs.
- Atlanta-Ready Comfort — Here in the Southeast, where summers are hot and muggy, a well-designed ventilation system can reduce indoor stickiness, lessen strain on your AC, and keep your home feeling fresh year-round.
Our Ventilation Design Process
At PV, our approach is straightforward yet thorough:
1 Assess Your Home:
Through a home energy audit or as part of an HVAC design consultation, we see how much air enters your home naturally and gauge existing insulation levels.
2 Check ASHRAE Standards:
We reference ASHRAE Standard 62.2, which determines whether your home meets minimum fresh-air requirements (or if it gets too much).
3 Seal and Filter:
If your home is leaky, we'll recommend air sealing. Then we specify filtration solutions to remove dust, pollen, and other contaminants from incoming air.
4 Select the Right Equipment:
Depending on your climate and preferences, we may suggest an ERV, whole-house dehumidifier, or a custom mechanical system.
5 Implement and Verify:
Whether we install the equipment or provide design guidance to your contractor, our goal is to ensure balanced ventilation that fits seamlessly with your HVAC system.

All About Ventilation: Key Details, Tips, and Benefits for a Worry-Free Home
Isn’t opening windows enough for fresh air?
It can help occasionally, but it doesn't address humidity or pollution reliably. A mechanical system is more consistent and also filters incoming air, making it healthier and more comfortable.
I live in a hot, humid area—won’t bringing in outside air make it worse?
Not if it's done right! Mechanical ventilation devices like ERVs and ventilating dehumidifiers remove excess moisture from incoming air, so your home doesn't become clammy.
Do I need a ventilation design if my home is new?
Even new homes can struggle with stale indoor air or high humidity—especially if they're tightly built to maximize energy efficiency. A proper ventilation plan ensures you still get adequate fresh air without wasting energy.
What if my home already has an air filter or air purifier?
Filters and purifiers are great, but they don't control how fresh air enters your space. Proper ventilation works alongside filtration to manage both air quality and moisture.
How do I get started?
Contact us! Whether you're building, renovating, or just trying to solve lingering indoor air problems, we can evaluate your home and design a customized ventilation solution that meets your comfort and health goals.
How does Atlanta’s high pollen count affect my ventilation needs?
During peak allergy seasons, opening windows can let in large amounts of pollen. A mechanically controlled system with proper filtration helps limit pollen infiltration, ensuring cleaner indoor air—especially for allergy sufferers.
Will adding ventilation equipment raise my energy bills?
Potentially, but proper system design typically offsets that cost by reducing uncontrolled air leaks. A sealed home with a dedicated ventilation device often uses energy more efficiently than a leaky home that relies on random airflow.
Is a whole-house dehumidifier always necessary in humid climates?
Not always. We assess each home's needs—sometimes, an Energy Recovery Ventilator (ERV) is enough. But in particularly damp conditions, pairing mechanical ventilation with dehumidification can help keep humidity in a comfortable range.
Can ventilation changes fix stuffy upstairs rooms in multi-level homes?
Absolutely. When we evaluate airflow, we can balance ventilation and identify any duct or return air issues that affect the upper floors. That way, every level stays fresh and comfortable.
Do local building codes in Atlanta require specific ventilation standards?
Atlanta follows Georgia's state building codes, which often reference ASHRAE guidelines for minimum ventilation. While not every home is strictly required to install mechanical systems, meeting or exceeding these standards vastly improves indoor air quality.
