HVAC Ventilation Design

Ventilation Design Services

Fresh, filtered air is essential for indoor comfort. But most homes are either improperly ventilated or barely ventilated at all.

Let the PV team deliver a house ventilation design that ensures you're always breathing clean, healthy air!

What are the advantages of house ventilation design?

A properly designed ventilation system does so much more than opening a window or relying on your home's passive ventilation. Advantages include:

  • Cleaner, healthier air
  • Better humidity control
  • Removal of indoor air pollutants
  • Reduced airborne allergens, like mold and pollen
  • Improved and consistent odor control

Homeowners who work with us on ventilation system design report improved quality of life in the ways such as:

  • Less humidity in summer and more humidity in winter
  • Fewer issues with allergies
  • Lower susceptibility to headaches and colds
  • Fewer lingering odors from pets, VOCs, and cooking smoke
  • Homes that feel less stuffy due to "old," stale air
  • I have had nothing but great experiences with PV Heating and Air. They have been servicing my home since 2007 and have always gone above and beyond my expectations

How to get started with home ventilation system design

At PV, we typically deliver house ventilation design as part of our HVAC consulting and design services.

In addition to designing and sizing your home's heating and air conditioning system, we ensure you get a ventilation system that delivers exactly the right amount of fresh air to your home. Here's how it usually works out:

  1. A homeowner, contractor, or builder approaches us for a home energy audit, Manual J load calculation, or other HVAC consulting service.
  2. As part of the process, we determine whether your home is getting enough (or too much) ventilation per ASHRAE Standard 62.2, which is a common standard for calculating the right amount of ventilation for a given home.
  3. We also consider how you're getting that ventilation now, whether it's through negative pressure ventilation or the home's passive ventilation (e.g. gaps and cracks where air enters and leaves).
  4. After that, we determine whether your home needs air sealing, filtration, and what kind of ventilation system, if any, is needed for the home.
  5. Given your home's attributes and your HVAC design, we guide you to the right ventilation equipment for your needs.

Controlled ventilation vs. uncontrolled ventilation

Uncontrolled ventilation is what you probably have in your home today. Air infiltrates your home via gaps and cracks around floor and attic penetration, not to mention doors and windows.

  • With this kind of ventilation, there's no way to control whether you're getting too much or too little air. And never mind humidity and airborne pollutants! You're at the mercy of mother nature and your home's construction quality.
  • It's the "bad" kind of ventilation that people often call us to tame.

Controlled ventilation usually involves a mechanical system. After determining where unconditioned, unfiltered air infiltrates your home, a home performance or HVAC contractor seals the offending air leaks and installs a ventilation device that's tuned to your home's needs.

  • The type of device depends on your home and your ventilation needs. In humid climates, the most common options are an energy recovery ventilator (ERV) or ventilating dehumidifier with fresh air. Occasionally, a custom system with ventilation fans and dampers is required.
  • With a controlled ventilation system, you can control the amount of ventilation you receive, keep humidity levels at a comfortable level, and filter all incoming air!

Does home ventilation design mean I'll need new equipment?

Possibly! In most homes where we provide home ventilation design, we recommend one of the following:

  • Energy Recovery Ventilator (ERV): An ERV is a mechanical ventilation system that simultaneously removes air from the home and introduces air from the outdoors. It also transfers heat and humidity from the more humid airstream to the less humid airstream, so your ventilation efforts don't result in too much or too little moisture in the air.
  • Whole-House Dehumidifier: A whole-house dehumidifier interfaces with your home's HVAC system and ductwork. It removes extra humidity from the air when your air conditioner can't remove enough on its own. You can also set up the dehumidifier to pull in fresh air and dehumidify it before introducing it to the home.

Other homeowners might also add fresh air systems or air cleaning systems, depending on their air quality priorities.

Those are the most common ventilation systems for homes here in the Southeast. When we provide ventilation design to clients outside this region, we might suggest a heat recovery ventilator (HRV), which works like an ERV except that it doesn't transfer humidity among airstreams.

Why choose PV for home ventilation designs?

Ventilation is serious business. Here's why you can trust us to get it done:


  1. We don't just design ventilation systems. We install them, too. This means we can anticipate challenges that other consultants have never encountered since they don't actually navigate sweltering attics or slog their way through crawlspaces like we do.
  2. Yours won't be the first ventilation system we've designed. Our seasoned team has numerous successful projects under its belt and knows exactly what steps to follow so that you enjoy A+ ventilation design.
  3. You get a lot more than just home ventilation system design. When you work with us, we include ventilation as part of an overall HVAC consulting package that ensures your home is as comfortable and energy efficient as possible.
