Exhaust Ventilation
An exhaust ventilation system should only be used in cold and dry climates. The major design flaw being that in humid climates, the drawn-in moisture can cause extensive damage to a home. Although they're relatively simple to install and initially inexpensive, they can raise energy costs over time.
Supply Ventilation
The next step up in ventilation is a supply system. Also on the less expensive and complicated side, these systems provide the homeowner with more control than exhaust systems and are better for hot climates. The use of outdoor and indoor air means a better regulated system overall, but supply ventilation can still increase heating and cooling costs.
Balanced Ventilation
The main benefit of balanced ventilation system is its versatility in all climates. It manages cold climates well without presenting the same risk of moisture damage as an exhaust system. Unfortunately, they're usually more expensive than exhaust or supply systems, but they also provide quality ventilation.
Energy Recovery and Heat Recovery
Energy recovery ventilators and heat recovery ventilators may initially cost more than their counterparts, but they can save money on bills in the future. They're designed for extreme climates, whether hot or cold, and to recover lost energy. Unfortunately, they're somewhat hard to install.
