Greater care for your indoor air Two-stage models are available with a super-quiet, high-efficiency variable-speed ECM fan motor option which circulates air for longer periods at a fraction of the cost. Longer run times mean fewer hot and cold spots and longer periods of air filtering, resulting in cleaner and more comfortable air. Plus, fewer starts and stops make variable-speed models 24 times less noisy than conventional furnaces.
