Why Does Hot Weather Make Ventilation Difficult?
While spot ventilation and natural ventilation have their place, these methods are easily overpowered by extreme heat. Additionally, they can worsen your home’s indoor air quality because they lack filtration mechanisms. Spot ventilation circulates existing indoor air pollutants and natural ventilation welcomes outdoor air pollutants. Together, these ventilation methods are a potential nightmare during the summer.
The alternative is mechanical ventilation. A mechanical ventilation system is more effective than spot and natural ventilation because it brings in filtered fresh air and exhausts stale air while helping cool the entire home.
These tasks may be difficult for A/C units in extremely humid or dry climates or for the A/C system alone. When temperatures are high, your HVAC condenser unit must work tirelessly to provide a comfortable atmosphere. This may lead to system failure if your HVAC system is unbalanced, lacks a dehumidifier or has an unclean air filter. And, consistently running the A/C will dramatically increase your utility bill. All of these factors can make summer season ventilation difficult. However, the right mechanical ventilation system will succeed.
Tip # 1
Use Spot Ventilation: These are localized mechanical ventilation systems that are useful in response to daily actions. For example, turn on range hoods and exhaust fans when cooking or showering as these activities increase indoor humidity. Also, ceiling fans and portable fans help reduce heat in a particular room.
Tip # 2
Natural Ventilation … But Wisely: The classic summer breeze … but there’s a smarter way to do it. Opening windows and doors in the early hours of the morning or in the late hours of the evening will be more beneficial than any other time of day. There won’t be as many cars on the road and the sun will not be at its peak. Also check the outdoor Air Quality Index and keep things closed on poor air quality days.
Tip # 3
Upgrade to Mechanical Ventilation: Turn on the A/C unit and enjoy cool, refreshing air throughout the day. A mechanical ventilation system installs directly into the HVAC system making an efficient upgrade. Ensure that home air filters and air vents are clean so as not to circulate contaminants.
Tip # 4
Consider Humidity Control: Regardless of ventilation method, a dehumidifier will remove moisture from the air thus reducing humidity. And in desert climates, a humidifier retains moisture indoors.
