The Benefits of a Home Air Ventilation System

Home air ventilation systems are extremely energy efficient – not only are they cost-effective; they’re able to recover nearly 70-80% of the heat contained in the indoor air that leaves your home. In addition, home ventilation systems eradicate harmful pollutants and allergens in the surrounding air without changing the temperature of your home. Installing a ventilation system in your home will also help to control the humidity levels in your home. Why is this important? Because overly dry or too-humid air can contribute to a variety of negative factors – possible sickness, damaged furniture or electronics, moldy bedding, and other unwanted occurrences.

Expert Tips

Frequently Asked Questions

Modern energy-efficient homes are tightly sealed to reduce heating and cooling costs. This tight construction limits the natural air exchange that historically diluted indoor pollutants. In Louisiana's climate, low ventilation concentrates humidity, VOCs from building materials, cooking byproducts, carbon dioxide from occupants, and biological contaminants indoors. Proper mechanical ventilation maintains healthy indoor air quality while allowing the home to remain energy-efficient.
Ventilation brings fresh outdoor air into the home, diluting indoor pollutants and replenishing oxygen. Air filtration cleans the air already inside the home by removing particles as it circulates through the HVAC system. Both address indoor air quality but through different mechanisms. Bienvenu Brothers installs both systems and advises on how they work together for comprehensive indoor air quality improvement.
Bienvenu Brothers installs energy recovery ventilators (ERVs), heat recovery ventilators (HRVs), exhaust-only ventilation systems, supply ventilation systems, and balanced ventilation configurations integrated with existing HVAC ductwork for residential and commercial properties throughout the New Orleans area.
An ERV is a mechanical ventilation system that brings in fresh outdoor air while exhausting stale indoor air. The key feature is a heat and moisture exchange core that transfers both heat and humidity between the incoming and outgoing air streams. This pre-conditions the incoming fresh air, reducing the energy cost of ventilating. ERVs are ideal for Louisiana's climate because they also transfer moisture, preventing the incoming humid outdoor air from overwhelming the HVAC system's dehumidification capacity.
An ERV is the better choice for Louisiana. HRVs transfer only heat between air streams. ERVs transfer both heat and moisture. In Louisiana's humid climate, an HRV would bring in outdoor air without managing its high moisture content, adding significant humidity load to the home. An ERV transfers a portion of the outdoor air's moisture to the drier exhaust air, significantly reducing the humidity penalty of fresh air ventilation.
In summer, the ERV exhausts hot, stale indoor air while pulling in hot, humid outdoor air. The exchange core transfers heat from the incoming outdoor air to the cooler exhaust air, pre-cooling the fresh air before it enters the home. It also transfers moisture from the incoming humid outdoor air to the exhaust stream, reducing the dehumidification load on the AC system. The result is fresh air ventilation with substantially less impact on indoor temperature and humidity than simply opening a window.
Yes. Bienvenu Brothers works with builders and general contractors to design and install ventilation systems for new residential and commercial construction throughout the greater New Orleans metro area. Louisiana building codes and ASHRAE 62.2 standards for residential ventilation guide our design recommendations.
ASHRAE Standard 62.2 specifies minimum ventilation rates for residential buildings based on floor area and number of bedrooms. A typical Louisiana home requires 30 to 60 CFM of continuous fresh air ventilation. Bienvenu Brothers calculates the appropriate ventilation rate for your home's size and occupancy during the installation assessment.
Ventilation does add some heating and cooling load because outdoor air must be conditioned. However, an ERV reduces this penalty significantly by pre-conditioning the incoming air. The energy cost of controlled ERV ventilation is modest compared to the health benefits of maintaining good indoor air quality, and it is far lower than the energy impact of ventilating by opening windows.
Stagnant indoor air with high humidity provides ideal mold growth conditions. Proper ventilation dilutes indoor moisture, reduces the concentration of airborne mold spores, and maintains the air movement that inhibits surface condensation on walls and ceilings. Combined with a whole-home dehumidifier, controlled ventilation provides comprehensive mold prevention.
Yes. Bienvenu Brothers installs and replaces bathroom exhaust fans, kitchen range hood venting, and laundry room exhaust fans. Proper exhaust ventilation in these high-moisture spaces prevents localized humidity accumulation that leads to mold growth on surfaces and deterioration of materials.
Balanced ventilation brings in and exhausts equal amounts of air, maintaining neutral pressure in the home. Exhaust-only or supply-only systems create pressure imbalances that can draw unconditioned air through wall cavities or push conditioned air into wall spaces, both of which cause moisture and energy problems. ERVs provide balanced ventilation by design and are the preferred approach for Louisiana homes.
Signs of inadequate ventilation include persistent musty odors, condensation on windows in cool weather, elevated indoor humidity despite AC operation, visible mold growth on surfaces, frequent headaches or respiratory discomfort when indoors, and carbon dioxide accumulation causing fatigue or reduced alertness. Bienvenu Brothers assesses ventilation adequacy during whole-home comfort assessments.
Yes. VOCs from building materials, furnishings, cleaning products, and paints accumulate in tightly sealed homes. Controlled ventilation dilutes VOC concentrations by continuously introducing fresh outdoor air. An ERV provides this dilution with minimal energy penalty compared to opening windows or doors.
Yes. Crawl space ventilation prevents moisture accumulation from ground evaporation and infiltrating outdoor air. Louisiana's high groundwater and frequent rain make crawl space moisture management particularly important. Bienvenu Brothers advises on crawl space ventilation and moisture control strategies appropriate for Louisiana's specific conditions.
Cooking produces particulates, moisture, grease aerosols, combustion byproducts from gas ranges, and odors that concentrate in the kitchen without adequate exhaust ventilation. Proper range hood ventilation exhausted to the exterior removes these contaminants at the source. Bienvenu Brothers installs and connects range hood ductwork to exterior exhausts as part of kitchen ventilation projects.
Maintaining indoor relative humidity below 50 percent through combined dehumidification and ventilation reduces the humidity that dust mites require to thrive. Lower dust mite populations mean lower allergen concentrations in bedding and upholstered furniture, providing meaningful relief for dust mite allergy sufferers.
ERVs can be connected to the existing HVAC ductwork, using the air handler fan to distribute fresh air throughout the home. Alternatively, they can operate with their own dedicated ductwork independent of the HVAC system. Bienvenu Brothers determines the appropriate integration method based on your existing system layout during the installation estimate.
Yes. ERV and HRV systems require filter cleaning or replacement every three to six months and core inspection annually. Exhaust fans require periodic motor lubrication and grille cleaning. Bienvenu Brothers includes ventilation system maintenance in annual HVAC service programs.
Radon levels in Louisiana are generally lower than in states with granite bedrock geology. However, sub-slab depressurization and proper basement or crawl space ventilation remain important where radon is present. Bienvenu Brothers advises on ventilation solutions in the context of radon mitigation when relevant.
Yes. Sick building syndrome symptoms including headaches, fatigue, eye and throat irritation, and respiratory discomfort are frequently linked to inadequate fresh air ventilation in tightly sealed buildings. Controlled mechanical ventilation that meets ASHRAE 62.2 recommendations addresses the primary cause of these symptoms.
Yes. Bienvenu Brothers installs and services commercial ventilation systems including makeup air units, energy recovery ventilators, and exhaust systems for commercial buildings, restaurants, offices, and multi-unit residential properties throughout the Metairie and New Orleans metro area.
Mechanical ventilation system installation typically requires a mechanical permit in Louisiana jurisdictions. Bienvenu Brothers handles all permit requirements as part of every ventilation installation project.
Louisiana residential construction follows the International Residential Code (IRC) which incorporates ASHRAE 62.2 ventilation requirements. Tightly constructed homes below 5 ACH50 air changes per hour require mechanical ventilation. Bienvenu Brothers designs and installs ventilation systems that meet current Louisiana code requirements.
Yes. ERV and HRV systems can typically be installed in existing homes using the existing HVAC ductwork for distribution, requiring only modest duct modifications for the fresh air intake and exhaust connections. Bienvenu Brothers minimizes the invasiveness of ventilation installations in existing homes.
For most Louisiana homes, an ERV providing balanced fresh air ventilation is the most impactful ventilation upgrade. It addresses indoor pollutant dilution, maintains appropriate air exchange, and manages the humidity of incoming fresh air, which is the critical factor that differentiates ERVs from other ventilation approaches in Louisiana's climate.

We are a BBB A+ rated, 4th generation family-owned HVAC company serving Louisiana since 1937. We understand the specific ventilation challenges of Louisiana's climate, particularly the need for humidity-managed fresh air ventilation that an ERV provides. Our licensed (LMP#7214WSPS) team designs and installs ventilation systems correctly, handles all permits, and provides ongoing maintenance to keep your indoor environment healthy. 89 years of regional expertise backs every recommendation we make.
A well-sealed home needs controlled mechanical ventilation more than a leaky one because it cannot rely on random air infiltration to dilute indoor pollutants. An ERV provides that controlled ventilation in a measured, efficient way. The tighter the home, the more important the ventilation system becomes. In Louisiana where energy-efficient construction is increasingly common, Bienvenu Brothers recommends assessing ventilation needs alongside any air sealing or insulation upgrade work to ensure the home remains healthy after tightening.
In Louisiana's climate, outdoor air is typically more humid than indoor air for much of the year, so standard ventilation without moisture management would add humidity. An ERV manages this by transferring moisture from the incoming humid outdoor air to the drier exhaust air stream, significantly reducing the humidity penalty of ventilation. Combined with a whole-home dehumidifier handling the residual moisture load, ERV ventilation provides fresh air exchange without undermining the home's humidity control. Bienvenu Brothers installs this combined approach as the recommended whole-home air quality solution for Louisiana homes.
