We spend 90% of our time indoors. So when we breathe in and out we slowly replace the fresh, oxygen-rich air inside with stale air that has high levels of CO2. In addition, the humidity also increases, such as when showering. Without proper ventilation in the house, mould and moisture problems develop.
Poor HVAC airflow can cause inconsistent temperature control, poor quality, and discomfort in your home.
Proper circulation is critical for temperature regulation, air quality, and even health and well-being. If you've noticed reduced airflow in your home, it's important to determine the root cause and improve circulation throughout your home.
Poor ventilation can have a significant impact on our health and well-being, especially when it comes to indoor environments like your home. Without proper air circulation, indoor spaces can become a breeding ground for harmful pollutants and toxins, leading to a range of negative health effects.
Effects of Poor ventilation can lead to a buildup of indoor air pollutants, triggering respiratory problems and allergies. Additionally, it hampers cognitive function, as increased carbon dioxide levels affect concentration and decision-making.
Poor ventilation in an indoor space can lead to carbon dioxide buildup. As a result, the oxygen levels in your indoor air will be reduced. This can cause a number of symptoms, such as fatigue, shortness of breath, decreased cognitive function and headaches.
CO2 levels that are higher than 1150 ppm will typically occur in bedrooms that are not fitted with a ventilation system and where windows and doors are closed. Above 2600 ppm: Insufficient ventilation—both sleep quality and next-day performance are adversely affected.
Air flowing freely throughout your home helps to regulate temperature, prevent buildup of particles and mold, and it makes breathing easier for everyone in your family. Also, if you enjoy cooking or use a lot of hobby supplies (glue, spray paints, epoxy, etc.), good air circulation can help dissipate odors and fumes.
How, then, to keep your IAQ A-OK? Prevailing wisdom is that at least 5 minutes—and ideally 15 to 20 minutes—a day of ventilation significantly improves indoor air quality. For a strong ventilation, open the front and back door, along with windows on the path in between, to get the baddies out.
To increase ventilation in your home, you can: Open windows and screened doors. Do not open windows and doors if doing so poses a safety or health risk to children or other family members (e.g., risk of falling or triggering asthma symptoms). Operate a whole-house fan, or an evaporative cooler, if your home has one.
Persistent Odors: Homes should refresh and clear out odors naturally through proper ventilation. If cooking smells, smoke, or other odors last longer than they should, it's likely your home isn't circulating air properly.
Good airflow helps keep the area dry and stops moisture from building up. This is important because too much moisture can cause mould and damage to the home. Subfloor ventilation usually uses vents and fans to move air. Vents are small openings that let air in and out.
So changes would be even smaller in most homes. Simply put, humans don't take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed, airtight room for 12 full days! Running out of oxygen in a room is quite unlikely.
Check your vents to see if they are not obstructed in any way. Remove any furniture or drapes blocking the airflow. While you are checking all the vents in your home, take a piece of cloth to clean the dust off the vents' grills. Fix any leaks and holes in your HVAC ductwork.
At low levels, stale air is uncomfortable, but at higher levels, stale air can become unhealthy. Breathing in unhealthy levels of stale air can cause skin irritation, headaches, and fatigue, and can be especially dangerous for individuals with underlying conditions like allergies or respiratory problems.
If there isn't a sufficient volume of air circulating through the system, the cooling and heat output will be greatly reduced. Insufficient airflow also leads to greater energy waste and higher energy costs. It also puts extra strain and increases the wear on the AC, furnace or heat pump as well as the blower.
Without proper ventilation in the house, mould and moisture problems develop. These are the possible consequences: Damage to the structural health of the home. Moisture problems and persistent mould patches.
If it's safe to do so, open doors and windows as much as you can to bring in fresh, outdoor air. While it's better to open them widely, even having a window cracked open slightly can help. If you can, open multiple doors and windows to allow more fresh air to move inside.
With a single opening in the room the main driving force for natural ventilation in winter is the thermal stack effect, where the air will flow into the room in the bottom half of the window and out of the room in top half of the window. The main driving force in summer will be the wind turbulence.
Change your furnace filter regularly. Avoid burning in your home, including fireplaces, wood stoves, gas appliances, and candles. Avoid chemicals such as air fresheners, sprays and cleaning products or use a healthier option. Vacuum your rugs and carpets regularly.
The Secret to Comfort is Balanced Airflow
The current Supply Air vent pressurizes the room, until (in many instances) the pressure inside the room slows the airflow coming from the Supply Air vent! When we install the Return Air vent, the pressure is alleviated. The Return Air vent balances the Supply Air vent.
Lack of ventilation or low ventilation rates are associated with increased infection rates or outbreaks of airborne diseases. High ventilation rates could decrease the risk of infection.
When air does not circulate properly in a space, patches of moisture, mould, or bacteria can grow. This may ultimately spread to other rooms or cause damage to your property. In extreme cases, it can also trigger allergies and health issues.
