You might feel like your home needs more fresh air from time to time. Apart from opening the windows, you could also make use of the ventilation system that is part and parcel of your HVAC system. Most homeowners are familiar with how the other letters in the acronym work, but they aren’t so sure exactly how their house is ventilated.

This could be the result of the several different types of ventilation systems that your home might have. Ventilation is very important because it helps to improve the overall quality of your indoor air. It allows the fresher outdoor air to take away from some of the significant indoor pollution. We’re going to give you a crash course on how the most popular ventilation systems work.

Local Exhaust Fans

Almost all homes have exhaust fans installed in key areas such as the kitchen or the bathroom. These fans draw up air that is unwanted in the home, such as humid air or smoke from a burnt dinner. The air they draw is released outside the house, allowing more room for fresh air to enter the room. This is ideal for getting rid of fumes, odors, or moist air in a specific room of the house but it won’t affect the entire home.

Supply Systems

Supply systems work in the opposite way of local exhaust fans. Instead of drawing air out of the room, ventilation systems are known for pushing air into the entire house and creating more pressure. This pressure forces the other air to leak out of the home through windows, doors, or any other available outlet. They will not control moisture or humidity, so you might want to consider that before deciding on a supply system for your ventilation.

Balanced Systems

Balanced systems should give you the best of both worlds when it comes to exhaust fans and supply systems. Using ductwork, a balanced system pushes new air into the home. There are also plenty of fans to release air out of the home, creating a system that has neither high pressure nor low pressure. This method still does not change the air to make it more or less moist upon entering the home.

Energy Recovery Systems

These are the most expensive ventilation systems to put in a home, but they work much harder than the other options. In an energy recovery system, moisture and heat will transfer from incoming air to the outgoing air. This makes your overall home environment much more comfortable and lowers your overall heating and cooling costs. Unfortunately, it might not lower your costs enough to offset the initial cost and installation of this system. The primary benefit here is in the quality of your indoor air.
