Perfect Window™ Fresh Air Heat Recovery Ventilation Systems as heat recovery ventilators provide proper levels of ventilation with energy savings by transferring heat between the exhaust and fresh air streams. The Honeywell Perfect Window™ Fresh Air Ventilation System removes stale, unhealthy air and replaces it with a stream of fresh air. Its powerful centrifugal blowers bring fresh air into your home and at the same time, exhaust stale humid air in an equal amount. Both incoming and outgoing airstreams pass through a heat exchange core where the energy from the exhaust air is efficiently transferred to the incoming fresh air. An air duct system supplies the fresh air brought in by the Perfect Window™ ventilator and distributes it throughout your home. Another duct draws the existing stale, humid air back to the Perfect Window™ ventilator and then exhausts it outdoors.

The main feature of the energy transfer core is that it will not waste your cool indoor air in the summer, and will not waste warm indoor air in the winter; 80% of the energy is saved which will means lower utility bills while you enjoy fresh air. This feature also makes this model versatile for climates of all temperatures, hot or cold alike.

The climate conditions where you live will determine whether you need a Heat Recovery Ventilator or an Energy Recovery Ventilator. HRV's are usually recommended for colder climates with longer heating seasons. ERV's are used for warmer, more humid climates with long cooling seasons.  Please see our helpful reference map to assist in selecting the right unit for you.
