When it comes to selecting the right ventilation system for your home, there are several options to consider. The choice depends on factors such as the size of your home, the layout, and the specific ventilation needs of each room.

Here are a few common ventilation system types to consider:

• Exhaust-only ventilation system: This type of system relies on exhaust fans to remove stale air from the house. It works by expelling air from rooms that generate the most moisture and pollutants, such as kitchens and bathrooms. The expelled air is replaced by fresh air drawn in through natural ventilation sources like cracks, gaps, and vents. This system is more suitable for smaller homes or individual rooms that require targeted ventilation.
• Supply-only ventilation system: In contrast to the exhaust-only system, a supply-only system focuses on supplying fresh air to the house. It uses fans to draw fresh air from outside and distribute it to various rooms. This creates positive pressure inside the house, forcing stale air to exit through natural ventilation sources. A supply-only system is often a good choice for homes with poor natural ventilation or when you want to control the source of fresh air.
• Balanced ventilation system: A balanced ventilation system combines both exhaust and supply features. It typically incorporates separate fans for exhaust and supply, ensuring an equal amount of air is brought in and expelled from the house. With this type of system, you have better control over the air exchange rate and can maintain a balanced airflow throughout your home.
• Energy Recovery Ventilation (ERV) system: An ERV system is designed to recover and transfer heat or coolness from the outgoing stale air to the incoming fresh air. This helps to reduce energy loss during the ventilation process. ERV systems are particularly efficient in climates with extreme weather conditions, as they minimize the amount of additional heating or cooling required.

Consider the specific requirements of your home and consult with a ventilation professional or HVAC specialist to determine the most suitable system type. They can assess your home’s unique needs and provide expert advice on the best ventilation system to install.
