iQ Drive Systems

Broan iQ Drive air conditioners, heat pumps and gas furnaces are the ultimate home comfort system. They use inverter technology, which was developed to be extremely efficient and very quiet. Here's how iQ Drive systems work:

Innovative inverter-rotary technology. The Broan iQ Drive air conditioner and heat pump utilize inverter technology to convert the electrical current from AC to DC. In doing so, the systems almost infinitely vary the compressor and fan speed motors. You'll also see this technology in Asian mini-split systems. Introduced in 2006, the iQ Drive air conditioner is the first ducted application of this technology for a typical North American residence.

Rarely shuts off. iQ Drive heating and air systems are different in that they are almost always running at a low level. The air conditioner and heat pump can modulate anywhere from 40% to 118% of capacity, instantly adjusting to exactly offset the demands on the home. Because these units do not cycle on and off like a traditional system, they save a lot of energy and reduce noise levels. In fact, sound ratings are 59-72 decibels, the lowest in the industry.

The Broan iQ Drive fully modulating gas furnace operates from 50% to 100% of capacity, and then as low as 15% of capacity by using time proportioning through the patent-pending controller. The system analyzes the indoor temperature once every 60 seconds and adjusts its percentage of firing accordingly. The three-phase motor makes the furnace very quiet.

Dehumidification mode. The iQ Drive air conditioner and heat pump deliver whole-home comfort, in part, through a dehumidification mode function. In very humid climates such as Alabama and Florida, you may still want a separate dehumidification system, but for average- to low-humidity areas, iQ Drive can provide an excellent source of humidity control.

Good Air Tip

Because iQ Drive systems are so unique, they require specialized factory training before installation. Make sure your Broan dealer is iQ Drive certified.
