Energy efficient homes consider mechanical ventilation as the ideal home building strategy. You may have heard a lot about the whole house fans, whole house ducts, full house ventilation, etc and all these terms possess no significant distinction and somewhat used interchangeably.

It’s hard to sense the effects of failing ventilation system early on. However, homeowners need to keep a close eye to the old or destructive ventilator to pre-avoid any health-related problems. 



What is whole house Ventilation?

Whole house ventilation is the latest expression of a mechanical system where an air continuously moves through the house at a considerably low rate. The aim is to provide your home with a consistent fresh air to maintain impeccable indoor quality.
Generally, two fans and duct systems are employed to remove the stale air and to bring the fresh air in. We classify whole house ventilation into various types, and each has pros and cons associated with it. 
 

Supply ventilation:

In supply ventilation, a home gets pressurized air, meaning a fan is used that pushes outside air inside while a duct or vent helps in leaking the stale air. Supply ventilation is not what we prefer for extreme weather but can go a long way for the mild climates. 

Exhaust Ventilation:

As opposed to the supply ventilation, exhaust ventilation is functioned to depressurize a home by exhausting air from a place. The major disadvantage of this ventilation is that pollutants or mold or dust from the attic, are more likely to draw into your home. 

Balanced Ventilation:

In balanced ventilation, two fans and ducts are used that banish the air wherever pollutants are likely to grow. This type of ventilation is the amalgamation of both supply and exhaust ventilation as the home neither gets pressurized nor depressurized. 

HRVs and ERVs

HRVs and ERVs are the energy system with a tendency to receive 60%-80% of energy exiting the system. These systems are built to minimize energy loss and control the ventilation inside a home.

Signs the ventilation needs attention:

To live in a healthy and comfortable place; we need to ensure our home meets all standards for an authentic style and ideal amount of ventilation.

Feeling tired to the bone due to high fatigue: The poor IAQ (indoor air quality) means the more exposure of occupants with contaminants or dust particle. When the air with pollutant is inhaled, it may impede the function of the lungs, making oxygen circulation difficult and a person feels more overtired or drowsy.

Stuffy air that leads to improper breathing: The visible sign of poor ventilation is when the air feels more stuffy, and you can’t breathe properly. Generally, a malfunctioning ventilation system that does not let the adequate amount of fresh air enter raises such issues.

Horrible smells: A horrible smell more like smelly socks and musty odors or feeling of dampness are the symptoms of poor ventilation. 

What happens if ventilation does not work:

Never let the ventilation system fail as it generates many issues related to your home aesthetics and health, including:

- Running water and moisture from cooking begins to build up around the ducts
- Accumulation of volatile organic compound
- High level of carbon dioxide
